not compatible  Time owned: 0 to 3 months
OK I own an ID880 which is great for d-star, so thought the 4100 would be good too,
biggest issue is its not compatible with 90% of the repeaters in my country, so mobile its useless. it is not capable of correctly decoding repeaters running ircddb software, only G3 Icom software repeaters, so it thinks its an FM signal and gives digital noise...currently trying to resolve with my icom dealer....
also why sell a mobile rig with a remote head cable, but no radio mounts? its a mobile radio, doesnt make sense to me.
the 880 beats the 4100 hands down for sensitivity, the 4100 gets scratchy inplaces where the 880 would still give a perfect copy.. so over all very disapointed with what should have been a really good radio

Poor display for driving  Time owned: 0 to 3 months
Just got a 4100 to replace the 880, and the display is just so hard to read, in VFO mode with just freq displayed its great, change to named memories with name shown, its tiny and most of the screen is left blank, a real waste of display real estate.. with the 880 and named memories its easy to read, the 4100, almost impossible in the vehicle... I am sure a firmware update to make it bigger or even scrolling would improve it greatly... otherwise its a nice radio

Excellent D-Star and FM  Time owned: 3 to 6 months
I love this radio. I have had the ID-4100A for about 3 months. It is being used in my shack and not mobile. It replaces an IC-208H.

The ID-4100A has excellent selectivity and receive audio. I continually receive excellent audio reports from D-Star and FM contacts. Plenty of functions and easy to operate D-Star. I totally recommend getting the RT software and program cable, it makes programming both FM and especially D-Star easy and you will get more out of this radio. RT software will gladly help you program over the phone which can be a must for new users.

I have been licenced since 1968, this is the finest mobile 2 and 70 radio I have owned or used.

Terminal & Access Point Mode Issues  Time owned: 0 to 3 months
I bought this radio to replace my ID-880H and use it for EMCOMMs in our local EOC on the DSTAR reflectors in either the Terminal or Access Point mode. This radio is a big improvement on the ID-880H. It has more features and the menu is much easier to use. However, the Terminal and Access Point modes do not work like a "DV Hotspot" as in a DV or DVAP Dongle or SharkRF. "You should be aware Terminal and Access Point modes only work using ICOM Callsign Routing. This means when you connect to another gateway through the internet and transmit, you will be heard there, but users who want to reply will need to know how to use Callsign Routing and capture your callsign (usually by pressing the radio's Callsign Capture button while you are still transmitting).  If they don't do that, you will not hear their reply.  The same applies to when you want to reply to a callsign routed call. This means Terminal and Access Point features do not support linked connections to reflectors. This fact is not always obvious from reading the sales literature."
I found out the hard way after purchasing one and trying to connect it up as a DV Hotspot. Here is ICOM response to my queries:
"The access point and terminal modes found in the ID-51A PLUS series and the ID-4100A are based around the JARL’s D-STAR protocol for callsign routing.  The functionality to connect to reflectors is based on third-party software, like dplus, that resides on most of the D-STAR repeaters.  While this is the functionality you desire, the limitation is that of their software to not recognize the ID-4100A as an access device to their network.  Once the third-party software providers incorporate the ID-4100A into their software, you should be able to have the capabilities you desire.  Until that date, the callsign routing functionality is all we can guarantee." ICOM offered to help me send it back to Gigaparts without paying the restocking fee, but I declined. Guess I'll have to wait for the third party solution to come along. The radio would be a 5+ if all the features worked as advertised.

Awesome Rig!!!  Time owned: 0 to 3 months
Purchased this little radio a month ago right when it came out and now that I have had time to play with it some I can honestly sit here and say it is GREAT... It has a nice receiver and I get terrific reports on my audio all of the time! If your looking for a nice compact dual band radio I highly suggest you pick one of these up!

Great Entry Level D-Star Transceiver  Time owned: 0 to 3 months
I'll readily admit that this is my first 'real' radio. I've had my Technicians license for a couple of months and stepped up from the Baofeng.

Analog works very well as expected andI've had no trouble hitting local repeaters. There are many scanning modes (and SO much faster than the Baofeng). There are 1000 memories and they can be grouped into up to 26 banks. A GPS is built-in.

D-Star is a fairly complicated subject and the manuals are very little help and actually confuse the matter to us noobs. If you check out the videos and help guides for the ID-5100, you can get enough help to work your way though. I've only managed to have 2 contacts in D-Star, but the sound quality is outstanding, very clear.

Since I'm a newbie, I'll list a few things I see as issues: The manual is pretty weak for D-Star. I've tried for hours and cannot seen to link to a gateway or Reflector. I'm fairly sure I've got the settings right. The menu system is fairly complicated and takes sometime to get the hang of where things are stored. If you set a priority channel scan, you'll get a gap in your reception every 4-5 seconds. This was hard to find. The use of YOUR and MY Callsign must be much easier to understand in Japanese. Why not use Local and Remote or similar? Including a light sensor to adjust the screen intensity at night would be helpful. Programming cord is overly expensive. Where is the Mac software for programming?
Icom tried hard to cover the complexity of programming DV, but in reality, they've made parts a bit more difficult. There are 4 settings required to contact a reflector, for instance. You can select the settings from a menu, but to see how the radio is set, you have to search the main menu for an item called 'Callsign' to check the settings.

Scanning near repeaters (DV and FM) is very cool and helpful. Capturing callsigns from the contacts is easy. Despite the complaints about the screen and the mike cord, I really didn't have an issue with them. On my mew MFJ meter, I get 5, 20, and 50 Watts transmitted.

This seems to be a throttled back ID-5100. The screen is a bit smaller and it doesn't have a touch screen. The 4100 doesn't have dual transmitters.

Overall, I'm happy with it. It's a good performer and I'll eventually get the D-star stuff worked out. For the small difference in price, I probably would have given the 5100 a little more consideration.
