Icom IC H Radio Transceiver | eBay
2820hh Used as a base station only I have had few problems. This model requires Yes this radio does have an extensive menu system which does require some learning but to me that is all part of the fun.
D-Star is unnecessarily complex requiring you to travel through various wormholes to get to your destination; it could and should be simpler. I tried 2280h access a local D-Star repeater that was about a mile away. The GPS alarm alerts you by beeping when a preprogrammed point is within m or 1km range from your location or anyone of preprogrammed points is within a preset square range.
The capsule mic element hole must be enlarged to help enhance the passage of low voice frequencies. It is under the control head and if you plug in the GPS antenna you cannot have the control head attached to the radio.
The rear panel has two SO antenna jacks to support diversity reception two antennas required. The addition of a 3u3 – 4u7 capacitor is pretty much mandatory and the capsule type, experimental perhaps. They do not show that once the board is installed there are two screws that hold the board down, the pictorial just shows it plugging into the slot, no screws shown.

This feature is useful when you are listening in a moving vehicle or the transmitting station itself is moving. Fast forward a few months. It appeared ixom fix the problem. Mic problems sorted, D-Star provides superb audio, but it requires ideal conditions to deliver the goods.
Well again I can see from the reviews I’ve read that many people should just start their own company because nothing that anyone builds is good enough for them. I assume I got into the machine ok, according to the S meter it replied but I received it in normal FM mode, not DV mode as the radio was set to. The one-touch reply function makes it easy to respond to a calling station instantly. Yes, easy to figure out but I almost reassembled the radio before I noticed the extra screws.
Xband repeat is as simple as pushing 3 buttons in at same time. Email Subscription You are not subscribed to this review. I used a modified Icom HMT mic and it produced excellent audio, but Icom should have sorted this problem long ago as it degrades many models.
Will do a follow up review in the future but as of now this is by far my favorite rig. One touch reply function The one-touch reply function makes it easy to respond to a calling station instantly.
In addition, up to 20 received callsigns are automatically stored as received call records. Once the conditions fall below a certain level, D-Star is sucked into a black hole, not a flaw, just the nature of the system.
Several hundred memories and several hours of work lost. Immediately back to thesame as before. The ICH receives Some mods advocate removing the felt cover from the capsule, and it’s been found the capsule may be clogged with Chinese glue, a new capsule is required.
The diversity function compares the receiving signal strength from two different antennas, ANT1 and ANT2, and automatically selects the strongest signal.
Obviously none of the above are killer issues and the radio itself is exceptional — so 4 out of 5. Mag mount control head is awesome. I get almost 60 watts on some portions of both bands. This is a complex rig and it takes a while to get your head around the menu systems.
FM transmission is not affected by this mod. Your location information can be sent simultaneously with the digital voice transmission. Separate controller from main unit The controller is separated from the main unit for flexible installation. There is of course the “falling off the cliff” and R2D2 sounds when on the fringe of repeaters but once you know the limits of the local repeater it is great. When available from a calling station, the ICH displays the distance and direction to the station.
Also, the cost is somewhat high when you consider that to add D-star, you need the UT module – an optional extra. In addition, tuning knobs and buttons for each band are arranged side-by-side, providing intuitive operation.

GPS alarm The GPS alarm alerts you by beeping when a preprogrammed point is within m or 1km range from your location or anyone of preprogrammed points icm within a preset square range.
Within a single band, the radio compares signal strength from each antenna and chooses the better signal to maintain good sound and receive quality.
One final comment, having been on D-STAR and I suppose any digital format I would not like to return to FM analogue – for mobile use it is the best, audio is great regardless of the signal strength, no picket fencing, it just works. The TX audio is tinny and pinched, devoid of low frequencies and must be modified to address the problems.
It would be nice is you could add a second board for this to work. This time it wiped iocm radio completely. I do use it in crossband mode it easy to do and works well.
