Outstanding   Time owned: 3 to 6 months
I got one of these a short time ago and think it is outstanding.It has lots of bells and whistles and D-Star is Great. I did several test on it and I dont understand why some say it has a SSB power problem. Mine does 117 watts, The secret to a good accurate reading is a meter with "Peak Hold". If your meter does not have peak hold then you have no right to give a SSB power reading. You can get one with FM, but for SSB use the correct equipment. I am pleased and proud it is in my shack.

Good radio that could be great  Time owned: 0 to 3 months
I bought this radio with intent of it being installed in the mobile. The size is right. I love that the head unit is only one cable to the main unit and the mic / headphones connect to the remote head. This is my first Icom so there was a little bit of a learning curve. I was able to get the hang of it rather quickly. In the box you get an abridged manual. The full manual is on the CD. I wish a nice printed full manual was provided. I have worked it on all bands including VHF FM and side band. Good audio reports were received. The main unit is quite small and very appropriate for a mobile installation. Doesn't have an integral tuner but this I knew. I may go with the LDG that is supposed to match this radio nicely.

Unfortunately, the HF sideband output RF power is inconsistent. I am able to get 100 watts (as seen through my MFJ 949E external tuner) on 80 meter and 10 meter for example. 20 meter and 17 meter won't break 50 watts. I went back and forth between my Yaesu FT-991 and the IC-7100. Same antenna, different radio but much less power on the Icom. Of course I knew about this issue prior to purchase and hoped that it was worked out with the new firmware. Sadly, it is not the case. I contacted Icom tech support and spoke to another ham who has the same radio and he confirmed the limited RF output was the radio functioning normally. He sounded frustrated as well. Almost like he didn't know what to tell me. I asked if a new firmware update was in the works to correct this and he stated he did not know.

I was able to program memories via Chirp. That was a welcome surprise. There was no official Icom programming software that came in the box. It appears they want you to purchase it.

I am currently getting used to the radio in the shack and have the head unit connected to the main radio via a 3 foot CAT5 patch cord. Works fine. The longer "official" extension cables are a small fortune. I am going to try a longer cable (probably shielded CAT6) to see if that works well. I am thinking it will work fine. What I want to do a lot of is keeping the antennas and main radio unit in the mobile and setting up a nice chair and table with a long interconnecting cable. You could probably do the same if you wanted to leave the main unit in the shack and kick back on your favorite easy chair.

I have only touched the surface of D Star. Seems already to be more intuitive than DMR. Audio quality maybe a little better. If I find it a nice feature, I may investigate a GPS unit to connect to the radio. Yet another item not included in the box (but I knew that of course)!

The pros may outweigh the cons. I think it will work very well in the mobile. If you are looking to get on VHF / UHF sideband it'll work very nicely. I wouldn't have this as a primary HF rig in the shack by any means however.

Does it all  Time owned: 0 to 3 months
I wanted to get back on VHF-UHF weak signal work with minimal investment so I traded my HF-only rig (TS-590) for this one.
My fear was that it was going to be a big trade-off on HF. Not so.
I am happilly surprised by the quietness of the receiver and the recovered audio. The selectivity is quite good for a rig of this size. Keep in mind that I have modest antennas so overloading is not an issue here. I was not a big fan of separated head design but I must say that combined with the touchscreen, it's make operation a breeze in most situation. It's a very good compromise as a complete
HF-VHF-UHF rig with enough features to keep the operator busy for a long time. The audio from the built-in speaker is loud and crisp, in fact this is the first radio I have that does not need an external speaker to sound good. At the actual street price on the used market, you cannot go wrong with this one.

Very Good  Time owned: 3 to 6 months
I've bought this radio around Christmas time and I could say that so far it has been a very good transceiver. I recommend it to anyone looking to buy an all band / all mode radio.

I like so much I have 3 of them  Time owned: 6 to 12 months
I wasn't a fan of this radio when I first saw it demoed. I bought one and it seemed like the low power complaints had people running for the exits. I paid $850 for the first and much less for the other two. I have one mobile 80 - 70CM, one for digital/second mobile and one for VHF/UHF in the shack. I love the SD card backup. I have the RT Systems software/cable and only need to update one and I can back it up with the others. Lots of memories, more than I will ever use. Low power on SSB, I will never know. If I ever use it for HF I will drive an amp at 35 Watts. I did the firmware update on one and the others were current. Nice radio. I replaced an Icom 7000, 2730 and an 208. I don't use the D Star as it is behind the mountain and I can't hear it and it can't hear me.

Trouble Touch Screen  Time owned: more than 12 months
I've had intermittent trouble with the touch screen since it was new. Sometimes it doesn't respond at all sometimes it responds when "it wants to ". I've done all the resets at one time or another, updated the firmware, to no avail. Only thing left is send it back for repair of an out of the box problem. When it works it's a great radio. touch screen doesn't work reliably. K4JQL owned this radio about 2years.

Great radio, don't do the capacitor mod  Time owned: 0 to 3 months
Had the radio for a few months now and while HF is relegated to another radio, this ic-7100 works great on VHF/UHF! It has much better sensitivity that my IC-7000 this replaced.
I did do the HF SSB mods for higher average power on SSB and I'll tell you this- It's not really needed and the capacitor mod actually messed up my FM mode.
Anything FM had a buzz in it- Apparently the portion of the transmitter that varies the carrier power is adversely affected installing the capacitor.
Adjusting the transmitter power down to drive my vhf/uhf amp stack led to hardly any contacts on repeaters. It made me think my radio or amp was messed up. Also to note the power bargraph looked like it was strobing (flashing) when transmitting. I thought it was odd.
Soooo.... I set up my IC-7000 in the car as the 7100 is in the home shack and I parked the car up the street and set the radio to record 146.520 while I executed some voice checks.
Then I listened to the recording. It sounded like the transmitter was turning on and off about 20Hz making my voice very choppy.
I removed the capacitor mod and all sounded good.
I did leave the soft mod in there jumping over the transistor collector to emitter to test the mod as that was more than enough to peg the meter at 130 watts PEP. I removed that mod too because there is a mic gain problem.
I don't care what your argument is, if you do these mods, you are going to mess up the FM/SSB mic gain balance no matter what. So if you do not plan to use the FM mode all is good.
Now this is what you mess up and no mod will balance this that I know of:
FM modulation gain will be way down versus SSB modulation will be through the roof so doing these mods you will effectively have to manually change the gain on the submenu whenever you change modes. I could not hear myself on 146.520 when I would talk it was so quiet. By the time I had the mic gain up enough (40-50% on FM) that when I switched back to HF SSB I was transmitting about 10W of ambient room noise the gain was so high. I had to turn the mic gain all the way down to about 4-6% to keep my HF mic gain normal.
If you know how to solve all the above issues, GREAT! But as it stands now, inputting 14VDC with a 25A power supply and NO mods with the default settings with the mic 3 inches from my mouth I do get 70-100W PEP with the compressor.
Your mileage may vary, but this is my experience.
Also to note others have mentioned the 15khz roofing filter is way too big for HF activities as it causes the AGC to pump whenever someone else is in the 15Khz passband. Playing with the PBT and setting BPF filter settings to the SHARP shape greatly reduced this action when PBT tuning is properly executed and was much better performing than my IC-7000.
Also don't expect the auto notch to block any agc action, it is after the agc whereas the manual notch and PBT IS in the AGC loop for maximum effectiveness against AGC pumping
Nothing is going to fix this perfectly other than a more narrowbanded roofing filter, I just miss the dual notch the 7000 had as it was much easier to "brick wall" QRM/QRN with the radio Macros in Ham radio Deluxe/ DM 780.
Obviously the roofing filter is stuck at 15Khz to allow FM ops with a simpler circuit so for what it is, it is a slam bang shack in a box with a integrated sound card with included DSTAR functionality.
As an afterthought, if Icom offered a optional color screen upgrade control head, I would not hesitate to buy as I am sure other owners would also jump on such a super option!

Great radio with updated firmware  Time owned: more than 12 months
Lots of controversy over that hack and slash solder job #90 on YouTube.
Icom America says don't do it.

"Thank you for contacting Icom America.
I would strongly advise against performing that modification because:
It voids your warranty
Highly probable that you will introduce ALC overshoot
What I can recommend is add 5-10db of Compression to bring up your average power"

When I took YouTube guy to task he didn't have an intelligent answer.
My radio with new firmware works perfect 98 watts
with a condenser Icom microphone.
If I need more I will buy a solid state amp and not over stress and over heat the radio

Pretty Good  Time owned: 0 to 3 months
I've owned mine about 6 weeks. Haven't had any of the problems mentioned. I need to reprogram it to add 2 and 440 meters and Dstar. Still getting used to it. So far so good.

Very nice radio!  Time owned: more than 12 months
I would rate this a 5 if it were not for the SSB power output issues. The latest firmware didn't help my power output much. I was outputting around 60-70 watts. After adding the 10uf capacitor mod, I regularly output around 120-130 watts now and audio is nice and clean. I use this radio a lot for digital modes and the audio capability in the USB cable eliminates any need for Signalink/sound card interfaces. I use D-Star occasionally. The IC-7100 is my base now, replacing my Yaesu 857D (which I put in my car). The Icom has more and better features. The IC-7100 does like 13.8v but will run down to 11.9v or so. As of 12/2016, it can be had for $869 with rebates. A steal for that price.
