I just picked up two of them on a bundle sale (one radio with free remote head kit). So far they are very good. My house is line of sight to a mountain with a LOT of 2way stuff on it and I have yet to hear any IM. Maybe in a big city area it will get overloaded, but none so far. I get great TX audio reports.
It does have a couple of quirks:
1- the lowest RX volume level is too high for use at home. I run an external speaker and made an 8dB attenuator out of resistors to cut the level going to the speaker. Now the lowest level is fine for a quiet room and there is plenty of up to go.
2- There is a button labeled TV/SQ which if you hold it it opens the squelch and momentarily changes the displayed channel name to the actual frequency. I like the later. But apparently there is some "TV" function and a "TV" output on the back. Maybe I'm confused, but I'm having a hard time rationalizing what a TV function is doing on a 2 way radio.
3- Bonus dislike: since only 7 characters are required to display the frequency, the channel name is also limited to 7 characters. These days we should get 8 minimum, 12 ideally. So it's a bit odd cramming in a repeater town name into 7 characters, especially where there are several repeaters in the same town and I want unique names for each one.
It has a couple of super great ideas IMHO:
1- the front control can be remote mounted using the remote kit. But, here's the great part, you really don't need the remote kit as the cable between the head and the radio is ETHERNET compatible. It's recommended to use CAT6 Ethernet so you get a larger conductor size to run the head over a long distance. But just not really having to buy a remote kit and using dirt cheap Ethernet cable is brilliant.
2- The fan, oh how I love this fan. It has yet to come on even when the radio is getting quite warm. I keyed down for a long time into dummy load just to hear it come on, and it's super quiet. Unlike several other radios from the past where the fan comes on the moment you key the mic and is so noisy that you have to turn the RX volume up. This radio is done very well in this regard.
3- bonus like: It comes out of the box fully unlocked. Any freq within it's range is all open. Just program and go, TX included.
Longevity, user friendliness and actual RF performance is still TBD.
