How to Program an IC-7100 — Step by Step

The radio with the wedge-shaped head. HF, 6, 2 and 70 centimeters plus D-STAR, in a two-box design where the whole control panel comes off on a cable and sits on the desk at an angle. A touchscreen, five soft keys, and no multi knob at all.

This page covers: Icom IC-7100. One model, so nothing here has to be translated from a near relative — every step below was written for exactly this radio.

Two things people copy from other Icoms that are wrong here

First, there is no USB SEND on this radio and no USB keying items. Those exist on the IC-7300, the IC-9700 and the IC-705, and guides written for those radios get copied onto this one constantly. The IC-7100 keys the transmitter from a computer by a CI-V command, by VOX, or by a hardware line into pin 3 or pin 7 of the ACC socket. There is nothing to switch on. Second, the USB cable presents two COM ports and only the first of them speaks CI-V. Icom says so plainly: one of them is USB1, used for cloning and CI-V operation. Point your logging software at USB2 and you get silence with no error, and there is no setting anywhere that moves CI-V onto it. There are also none of the later radios' CI-V USB items — no CI-V USB Port, no CI-V USB Baud Rate, no echo back. The baud rate and the address are global and shared between the USB cable and the round REMOTE jack.

No multi knob, no function keys — the MENU key pages the soft keys instead

If you have used an IC-7300 or an IC-705 you will look for a MULTI knob and there is not one. What this radio has instead is a pair of concentric knobs marked M-CH and BANK, and a MENU key that swaps what the five on-screen soft keys do. Push MENU once and you are on M-1, which carries scan, split, A over B, VFO and memory, and memory write. Push again for M-2, which changes with the mode. AGC is there in SSB, SSB-D, CW, RTTY, AM and AM-D and nowhere else — in FM, FM-D, WFM and DV that key is simply not on the row, which is why hunting for AGC on an FM channel gets you nothing. Beside it, the compressor and transmit bandwidth appear in SSB, the keyer in CW, the decoder in RTTY, and tone squelch in FM. Push again for M-3, with MEMO — which is the memory menu, not the memo pad; the memo pad has its own MPAD key on the front panel — plus the scope, the SWR meter and VOX. In D-STAR's DR mode it is two menus rather than three. MENU is also the universal back key: inside almost any sub-screen, pushing it takes you up one level. The concentric knobs change job too, and two lamps tell you which: with both out they select memory channels and banks, with the green one lit they are the passband tuning, and with the orange one lit the inner knob is the RIT and the outer one does nothing at all.

What you can do on this radio

Rather do this on your phone, standing at the radio?

The app walks you through the same steps one at a time, on a screen sized for a phone.

Open Radio Rosetta

Set the radio up for FT8 and other digital modes on an IC-7100

Two touches for the mode, and one menu item for the thing that actually matters — which socket your computer's audio arrives on. The factory setting is not the one most people want.

  1. Touch the mode icon to open the mode selection screen.touch the mode iconThe screen should show: SSB, CW, RTTY, AM, FM, WFM, DV — and in SSB, AM or FM, a DATA block as well.
  2. Touch DATA. The screen closes and you are in a data mode.touch DATAThe screen should show: The mode icon gains a -D.Watch out. Check the sideband before you go any further. This radio picks USB above 10 MHz and LSB below it, and LSB-DATA is a perfectly valid mode it will happily sit in. On 40 meters that means DATA comes up on lower sideband, which is not what FT8 wants. Touch SSB again to toggle it to USB.
  3. Push SET, go to Connectors, then DATA MOD, and choose USB.SET›touch Connectors›touch DATA MOD›touch USBThe screen should show: DATA MOD with MIC, ACC, MIC and ACC, or USB.The default is ACC — the thirteen-pin socket on the back — because this radio predates everybody running one USB cable for everything. If your computer is on the USB socket, this has to say USB or nothing you send will be modulated. The touch is the save; there is no confirm.
  4. While you are in Connectors, USB MOD Level is the drive control for that socket. It runs 0 to 100 percent and ships at 50. Push SET to leave.touch USB MOD Level›touch the plus and minus›SETWatch out. There is a matching ACC MOD Level, and turning that one down while your audio is coming in over USB does exactly nothing. Adjust the one that matches what DATA MOD says.

One setting in the same menu can silently kill your decoder and it is easy to wander into: ACC and USB Output Select. On AF, which is the default, the USB socket gives your computer receive audio. On IF it gives a 12 kHz intermediate frequency instead, which exists for software-defined-radio and DRM work. Flip it looking for something better and WSJT goes deaf with no error anywhere. Two other things. Install Icom's USB driver before you ever plug the cable in — the manual says never to connect the radio to a PC until the driver is installed. And the manual's own note about which of the two data connectors the DATA MOD Level item scales is genuinely unclear: there is a DATA1 jack and a DATA2 socket, DATA is not one of the choices in DATA MOD at all, and Icom never reconciles it. For a USB cable and a computer, none of that matters — USB MOD Level is your control.

Taken from the manufacturer's own manual for this model.

Connect the radio to a computer on an IC-7100

The settings themselves are simple and the defaults are mostly right. What stops people is not a setting at all — it is choosing the wrong one of the two COM ports the cable creates.

Have these to hand before you start

  • Icom's USB driver, installed before the cable is ever plugged in.
  • The knowledge that the cable gives you two COM ports and only one of them works.
  1. Install Icom's USB driver before connecting anything.install the USB driver firstWatch out. Icom's instruction is in capitals in the manual: never connect the transceiver to a PC until the USB driver installation has been completed.
  2. In Windows you will see two COM ports appear. Choose the first one — USB1.pick USB1 in your softwareIcom's own words: one of them is USB1, used for cloning and CI-V operation. The other is USB2 and does something else entirely. There is no setting that moves CI-V onto USB2, so if you pick the wrong one you get complete silence and no error message. It is the first thing to check.
  3. Push SET, then Connectors, then CI-V, then CI-V Baud Rate.SET›touch Connectors›touch CI-V›touch CI-V Baud RateThe screen should show: 300, 1200, 4800, 9600, 19200 or Auto.Auto is the default and is usually right — the radio matches whatever the software is using. Pin it to a fixed rate only if something is unhappy.
  4. Push MENU to come back up to the CI-V list, then touch CI-V Address. It is 88h on this radio — that is the number your software wants in its rig address box.MENU›touch CI-V AddressThe screen should show: A hex value between 01h and DFh, with 88h as the default.Watch out. Leave it alone unless you have two Icoms on the same bus. Change it and every piece of software you own has to be told the new number. Note that this one setting is shared — the USB port and the round REMOTE jack use the same address and the same baud rate.
  5. Push MENU again to get back to the list, then touch CI-V Transceive. It ships ON, which makes the radio announce every change you make on the front panel. Turning it off is often the fix when software keeps losing track. Push SET to leave.MENU›touch CI-V Transceive›touch OFF›SETThe screen should show: OFF or ON.That unsolicited traffic arrives in the middle of a conversation and some logging and digital software reads it as a reply. If the address and the port are right and it still misbehaves, this is the next thing to try.

Now the part the family note above flags, and that is worth repeating here because it is where people lose an evening: there is no USB SEND on this radio and no USB keying items. Search this radio's whole menu and you will not find one. What the IC-7100 has instead is three ways to key it from a computer — a CI-V command, VOX, or a hardware line. The hardware line is pin 3 or pin 7 of the ACC socket, taken to ground; which of the two depends on band, and the VSEND Select item decides where the split falls. Pin 3 of the DATA2 socket does the same job. There are also none of the later radios' CI-V USB settings. If a guide tells you to turn on USB SEND on an IC-7100, it is describing a different radio.

Taken from the manufacturer's own manual for this model.

Set the drive level for digital modes on an IC-7100

One level item per socket, and a power control that is a key and a knob rather than a menu.

  1. Check DATA MOD first. Whatever it says is which level item you need.SET›touch Connectors›touch DATA MODThe screen should show: MIC, ACC, MIC and ACC, or USB. The default is ACC.This coupling is the trap and Icom never spells it out as a warning. If DATA MOD says USB and you turn ACC MOD Level down hunting for less drive, nothing whatsoever happens.
  2. Push MENU to come back up to the Connectors list, then touch the level item that matches. USB MOD Level, ACC MOD Level and DATA MOD Level all run 0 to 100 percent and all ship at 50. The dial adjusts them too.MENU›touch USB MOD Level›touch the plus and minus›SETThe screen should show: A percentage.50 is the sensible starting point. Move it a few percent at a time.
  3. Touch the meter to switch it to ALC before you transmit.touch the meterThe screen should show: The meter cycles through power, SWR, ALC and compression. Touching it for a second gives you all of them at once.Watch out. Icom prints no ALC target for data mode anywhere in either book. The usual rule applies — a small amount of ALC deflection, well short of the top — but that is our advice rather than theirs, so watch your own signal.
  4. For power, push MIC/RF PWR and turn the outer BANK knob.MIC/RF PWR›dial → BANKThe screen should show: The output power adjustment window.The ranges are 2 to 100 watts on HF and 6 meters, 2 to 50 on 2 meters, and 2 to 35 on 70 centimeters, with AM lower again. And the setting is remembered separately for every band, so setting 30 watts on 20 meters leaves 2 meters wherever it was.
  5. Push MENU to close the window.MENUWatch out. Icom prints two different keys for this in two different places — MENU in the procedure, and a second push of MIC/RF PWR in the panel description. Both are in the same book. Either is worth trying; neither will hurt anything.

One thing that follows from DATA MOD and is worth knowing before it puzzles you: when you are in a data mode with the modulation coming from the back of the radio, the microphone is muted. That is deliberate, and it is why Icom's microphone gain procedure lists SSB, AM, FM and D-STAR and pointedly does not list the data modes. If you drop out of DATA to make a voice contact and the microphone seems dead, check which mode you are actually in.

Narrow the filter to shut out the station next door on an IC-7100

Three filter slots per mode, and each of them is a number you can change rather than a piece of hardware. The whole thing is done by touching one icon on the screen — briefly to switch, for a second to edit.

  1. Touch the filter icon at the top of the screen to step through the three filter settings.touch the filter iconThe screen should show: The chosen width and shift appear in a window for a couple of seconds.Which filter you last used is remembered per mode, so your CW choice does not follow you into SSB. On the optional HM-151 microphone the FIL key does the same thing.
  2. Touch and hold the same icon for a second to open the FILTER screen and edit the widths.touch the filter icon›hold it for a secondThe screen should show: A trapezoid of the filter shape, with BW and SFT down the left and the mode and filter number at the right.This is the good part. The three slots are not fixed hardware filters — you can set each one to whatever you want within the range for that mode.
  3. Touch BW, turn the dial to the width you want, then touch BW again to set it.touch BW›dial → the width›touch BWThe screen should show: BW blinks while you are editing and the trapezoid changes shape.In SSB the factory widths are 3.0, 2.4 and 1.8 kHz and you can put any of the three anywhere from 50 to 500 Hz in 50 Hz steps, or 600 Hz to 3.6 kHz in 100 Hz steps. Data and CW start at 1.2 kHz, 500 Hz and 250 Hz over the same range. RTTY tops out at 2.7 kHz. AM gives you 9, 6 and 3 kHz adjustable from 200 Hz to 10 kHz. FM, FM-D and D-STAR are fixed at 15, 10 and 7 kHz. WFM is fixed too and is the odd one out — a single filter at 280 kHz, with nothing to choose between.
  4. In SSB, data and CW there is also a filter shape — touch the fifth soft key to swap between sharp and soft.touch SHARPWatch out. The label on that key tells you what is selected now, not what pressing it will do. Icom's own screen callouts say so: when SHARP is selected, touch SHARP to select SOFT. Read it as a status light rather than a button.
  5. Push MENU to leave the FILTER screen.MENUHolding the filter icon for a second again does the same.

Three things to watch. Changing a passband width clears the passband tuning shift on that filter, so set the width first and shift afterwards. In FM, choosing filter 2 or filter 3 does not only narrow your receiver — Icom says it changes your transmit modulation to the narrow 2.5 kHz setting as well, which is a receive control quietly changing what you put on the air. And DEF held for a second puts a filter back to its factory width, which is the way out if you have narrowed yourself deaf. For continuous narrowing rather than three fixed choices, the passband tuning is the other tool: push the M-CH switch until the green lamp lights and the two concentric knobs become the passband controls, in 50 Hz steps on SSB, CW and RTTY. Holding that switch for a second puts the passband tuning back to center.

Turn on noise reduction on an IC-7100

A key and a dial. Fifteen steps, and Icom is explicit that more is not better.

  1. Push NR to switch it on.NRThe screen should show: NR appears among the function icons.
  2. Hold NR for a second to open the level screen, then turn the dial. Clockwise is more reduction.hold NR›dial → the levelThe screen should show: A bar graph with a number beside it.The range is 1 to 15. Icom prints no default anywhere, so the number in their illustration is an example rather than a specification — we are not going to publish it as one.
  3. Push NR again to close the screen. Another push switches the noise reduction off.NRWatch out. The same key does both, one after the other — the first push closes the adjustment, the second turns the function off.

Icom's own guidance is worth quoting rather than paraphrasing: a large rotation of the noise reduction control results in audio signal masking or distortion, and you should set it for maximum readability. In other words find the point where the voice or the code is easiest to copy, not the point where the noise is quietest. Those are usually different settings, and the second one tends to be too high. If you need a reference point, DEF held for a second on that screen puts the level back to factory.

Taken from the manufacturer's own manual for this model.

Turn on the noise blanker on an IC-7100

For pulse noise. Same shape as the noise reduction — one key, held for a second, gets you the settings — but this one has three of them rather than one, and the third is the useful one.

  1. Push NB to switch it on.NBThe screen should show: NB appears among the function icons.Watch out. It works in SSB, CW, RTTY and AM only. In FM, wide FM and D-STAR it does nothing at all.
  2. Hold NB for a second to open its settings.hold NBThe screen should show: The NB screen, with up and down arrows and a DEF key.
  3. Use the arrows to pick which of the three settings you are on, and the dial to change it.touch the arrows›dial → the valueNB Level is the threshold, 0 to 100 percent, default 50 — how big a pulse has to be before the blanker acts on it. NB Depth is how hard it cuts, 1 to 10, default 8. NB Width is how long a pulse it blanks, 1 to 100, default 50, and that is the one worth experimenting with: a blanker set for short sharp ignition pulses does nothing against the long ragged ones from a switching supply or an electric fence.
  4. Push NB to come back out.NBWatch out. DEF held for a second puts whichever setting you are on back to factory, which is the way back if you have made things worse.

Icom's own warning, near enough verbatim: with the blanker on, received signals may be distorted if they are excessively strong, or if what you are trying to blank is not actually pulse noise. Their suggested fix is to set the threshold shallower or turn the function off. In practice that means a blanker turned up hard on a crowded band will make a strong nearby signal sound broken, and it is worth switching off as a test whenever something sounds wrong that did not an hour ago. One documentation oddity for anyone following along in the book: Icom prints the on-and-off gesture as a touch on the display in one line and as the physical key everywhere else. The rendered page settles it — NB is a physical key on the center bottom of the head.

Notch out a whistle or a carrier on an IC-7100

Both kinds on one key, and which one you get depends on the mode you are in.

  1. In SSB or AM, push NOTCH to cycle the notch between automatic, manual and off.NOTCHThe screen should show: AN appears for the automatic notch, MN for the manual one, and no indicator at all when it is off.Those two letters in the function icon row are how you tell which one is running. The automatic notch hunts for a steady tone and pulls it down by itself, even as the tone drifts; the manual one you place where you want it.Watch out. The three-way cycle is only SSB and AM, and only if both halves are enabled. Two Set mode items decide that — Function, then [NOTCH] Switch (SSB) and [NOTCH] Switch (AM), each of which can be set to Auto, Manual or Auto/Manual. Both ship on Auto/Manual. Set one to Auto and the manual notch is simply not in the cycle any more, which is worth knowing before you conclude the key is broken.
  2. In CW and RTTY the key is a two-state switch and the only notch you get is the manual one. In FM it is also two-state and the only one you get is the automatic.NOTCHThe screen should show: MN in CW and RTTY, AN in FM.So there is no automatic notch in CW — which is just as well, since a CW signal is exactly the steady tone an auto notch is built to remove.
  3. With the manual notch already on, hold NOTCH for a second to open the NOTCH screen. Touch WIDTH to pick WIDE, MID or NAR, then turn the dial slowly until the tone disappears.hold NOTCH›touch WIDTH›dial → the notchThe screen should show: The NOTCH screen, with the notch position on it.Icom asks for slow — the filter is sharp enough that a normal tuning rate walks straight past the null. The range depends on the mode: minus 1040 to plus 4040 Hz in SSB and RTTY, minus 5060 to plus 5100 in AM, and in CW it is your pitch frequency plus or minus 2540 Hz.Watch out. Icom's procedure has you turn the manual notch on first — push NOTCH once or twice until MN shows, then hold. Whether the hold does anything with MN off is not something either book states.
  4. Push NOTCH to leave the NOTCH screen.NOTCHThe screen should show: Back to the normal display.

The automatic notch is the one to reach for against a steady carrier in a voice mode — it finds it without your help, it copes with a tone that drifts, and Icom's own illustration shows it handling interference whose frequency is changing. The manual notch is the one for when you want to see exactly where the null is sitting, or when the automatic one keeps grabbing something you wanted to keep, and it is the only one available in CW and RTTY. Two practical notes. The width control on the NOTCH screen is worth using: NAR against a single clean carrier does far less damage to the signal around it than WIDE. And if you have set one of the [NOTCH] Switch items to Auto or Manual to simplify the cycle, remember you did — it is a Set mode item nobody thinks to check.

Work a DX station that is running split on an IC-7100

The quick way is a one-second touch, and there is a second trick underneath it that most people never find: you can type the offset in kilohertz instead of hunting for it.

Have these to hand before you start

  • The frequency the DX station is transmitting on.
  • Where he is listening — up 5, or a range.
  1. Tune VFO A to the station you can hear, in the mode you will use.dial → the DX station's frequencyThe screen should show: His frequency.
  2. Push MENU until you are on the M-1 screen, then touch SPLIT and hold it for a second.MENU›touch SPLIT›hold it for a secondThe screen should show: SPLIT appears, and the transmit frequency shows alongside.That one gesture switches split on and copies your receive frequency into the transmit VFO. Quick split is on from the factory. If your SPLIT Offset is set to something other than zero it applies that offset at the same time — with the factory setting of 0.000 MHz it simply equalizes the two.
  3. Hold XFC down and turn the dial to set how far up or down you will transmit.hold XFC›dial → the offsetThe screen should show: You hear your transmit frequency while you hold XFC, and the display goes back to the receive frequency when you let go.This is the part worth learning. You find out whether the frequency you picked is already occupied before you call, rather than after somebody tells you. While XFC is held you can change the band and the mode on the transmit VFO too.
  4. A plain touch on SPLIT turns it off again.touch SPLITThe screen should show: SPLIT disappears.

Two things worth setting up before a pileup. The first is Split Lock, which is off from the factory and which Icom describes exactly right: without it, accidentally letting go of XFC while you are turning the dial moves your receive frequency instead of your transmit frequency. Switch it on under Function, SPLIT and DUP, SPLIT LOCK, and then hold SPEECH and LOCK for a second while split is running — after that a slipped thumb costs you nothing. The second is the typed offset. Touch the megahertz digits, touch F-INP, and you can key the shift straight in: 1, 0, then SPLIT gives you 10 kHz up. For a downward shift, touch the minus first — the SPLIT key changes to minus SPLIT to show you it is going the other way. The range is plus or minus 9.999 MHz in 1 kHz steps. One last note: switching on the one-touch repeater function turns split off automatically.

Taken from the manufacturer's own manual for this model.

Save a frequency to a memory channel on an IC-7100

All of it happens on one screen, with five soft keys along the bottom — and the key that stores and the key that erases are next to each other, both fired by a one-second hold, neither with a confirmation.

  1. Set the frequency, the mode and the filter you want kept.dial → the frequency›touch the mode icon›touch the filter icon
  2. Push MENU until you reach the M-3 screen, then touch MEMO.MENU›touch MEMOThe screen should show: The memory screen, with LIST, SEL, MW, M-CL and V/M along the bottom.
  3. Pick the channel you want with the inner M-CH knob, using the outer BANK knob if you are working in banks.dial → M-CH›dial → BANKThe screen should show: BLANK under the number means the channel is empty.Not the main Dial. With the memory screen open the Dial still retunes the frequency in the channel you are sitting on — the concentric knobs are what move between channels.
  4. Touch MW and hold it for a second to write.touch MW›hold it for a secondThe screen should show: BLANK disappears.Watch out. Two things at once here. A tap does nothing — it has to be a hold. And Icom's own note: if you do this on a channel that already has something in it, the previous contents are overwritten, with no prompt. The key immediately to the right, M-CL, erases the channel on exactly the same one-second hold. One key-width of finger error is the difference between saving a channel and destroying it.

Two more one-second holds on the same row, both of which do something you might not expect. V/M held for a second copies the channel you are looking at into the VFO — and Icom's own illustration caption is worth repeating: the display does not change. A destructive write to your VFO with no visual feedback whatever, on a key sitting right beside the erase key. And on the memory list screen, pushing QUICK and touching Edit Name gets you the name editor — QUICK does not offer Edit Name at all if the channel is blank. If you are about to do any bulk memory work, back up to an SD card first; the radio can write its whole configuration to one.

Run the antenna tuner on an IC-7100

There is no tuner inside this radio. Icom's own key description says optional automatic antenna tuner, and that word is doing real work — the TUNER key drives an accessory you have to buy.

  1. On HF or 6 meters, push TUNER/CALL to switch the tuner in or bypass it.TUNER/CALLA short press is the in-or-out toggle. Nothing is tuned by it.
  2. Hold TUNER/CALL for a second to tune.hold TUNER/CALLWatch out. The radio transmits to do this. Make sure an antenna is connected and you are on a frequency you can legally use before your thumb rests there.
  3. If it cannot find a match within twenty seconds the radio bypasses the tuner automatically and stops.wait for it to finishThat is a documented timeout rather than a fault. Twenty seconds of trying and no match means the antenna is outside what the tuner can do, and the answer is the antenna rather than another attempt.

Which tuner you have changes the rest of the story. Both the AH-4 and the AH-740 are remote units that live at the antenna. The AH-4 matches a long wire — more than 7 meters of it, 3.5 MHz and up — which is why it is popular with portable operators. The AH-740 is a whip system in its own right, covering 2.5 to 30 MHz with the whip Icom supplies. An AT-180 is a conventional in-shack tuner for coax-fed antennas. Both are driven by this same key, and both have their own full procedures in Icom's Full Manual rather than the Basic one. On 2 meters and 70 centimeters the key does something completely different — it is the call channel key up there, which is why the legend has two words on it.

Set the CW keyer speed and weight on an IC-7100

A dedicated key, and both of the concentric knobs do something useful once you have pushed it.

  1. Push SPEED and PITCH to open the adjustment window.SPEED/PITCHThe screen should show: The key speed and CW pitch display.
  2. Turn the inner M-CH knob for the keyer speed. The range is 6 to 48 words a minute.dial → M-CHThat is the keyer's sending speed. Send with the paddle while you set it.
  3. Turn the outer BANK knob for the CW pitch — 300 to 900 Hz in roughly 5 Hz steps.dial → BANKThis shifts both the tone you hear on receive and your own sidetone together, without moving the frequency you are actually on. Worth setting to whatever is comfortable to listen to for an hour.
  4. Push the key again to close the window.SPEED/PITCH

The rest of the keyer is in its own menu rather than the main Set mode, which catches people out. In CW, push MENU to reach the M-2 screen and touch KEYER. Out of the box that lands you on the KEYER SEND screen rather than the keyer root — the "KEYER 1st Menu" item in the Function Set mode ships on KEYER-SEND — so push MENU once more to come up a level, and from there touch SET on the screen — not the SET key — to reach the keyer settings — the sidetone level, the dot to dash weight, the paddle polarity, the keyer type and the repeat time for the memory keyers. That is a separate tree from everything else on the radio and nothing in the main Set mode will take you to it.

Taken from the manufacturer's own manual for this model.

Reset the menu to factory settings on an IC-7100

Two resets, and the gentle one really is gentle — Icom prints an eleven-item list of what it leaves alone. There is also a power-on key combination, and it is worth knowing which of the two it does.

  1. Push SET, then Others, then Reset.SET›touch Others›touch ResetThe screen should show: Two entries: Partial Reset and All Reset.
  2. Touch Partial Reset, then YES at the prompt.touch Partial Reset›touch YESThe screen should show: PARTIAL RESET appears and the radio restarts.This puts the VFO frequencies, the VFO settings and the menu contents back to factory and leaves a great deal alone: your memory channels, the D-STAR repeater list, the call sign memories, your transmit messages, the GPS memories and messages, your programmed band edges, the memory keyer contents, the DTMF memories, the RTTY memories, and the reference frequency adjustment. That last one matters — it is the calibration, and a reset that took it out would leave the radio off frequency.
  3. All Reset is the other branch, not the next step. The partial reset above restarts the radio, so come back through SET, Others, Reset first. All Reset then asks twice: touch All Reset, read the warning, touch NEXT, then YES.touch All Reset›touch NEXT›touch YESThe screen should show: The first box asks if you are sure and tells you to read the next caution. The second says it clears all settings and memories and disables DR mode.Watch out. That second warning is the real one. All Reset wipes the D-STAR repeater list, and the repeater list is what DR mode runs on — so afterwards the radio cannot do DR mode at all until you reload it. Icom's own recommendation, marked recommended in their manual, is to save everything to an SD card or to a PC with the CS-7100 software first.

There is a power-on combination for when the touchscreen has stopped responding and you cannot get into the menu at all: hold SET, SPEECH and LOCK, and MPAD together, then push the power switch. Be clear about what that does — it is an All Reset, not a partial one, and it runs with no confirmation dialog whatever. There is no power-on shortcut for a partial reset. So if the radio is merely behaving oddly rather than unusable, go through the menu and choose Partial, because the combination is the destructive one. Back up to an SD card before either.
