Jon.... I have been using the radio for about a month now. The audio is better than any previous GRE HT. Quite good, actually -- Substantial volume if you want it. Batt. life depends.... Many people, including me, have trouble reading the screen unless there is some amount of backlight. I have mine programmed as 'always on' at the lowest setting. With this on, I probably get about 6-7 hours continous with NiMh batts. Several owners report up to 12 hours with the backlight off.
There are two common complaints about the PSR-800. One, the device is not dust proof, and dust gets in behind the display glass. I put smartphone screen saver stuff on mine when I got it, but I am not sure that solves the problem -- Personally, I have no dust. Second, ALL user grade scanners have issues of handling Trunk CC handoffs. Some lock on to the strongest, and won't release. The 800 has logic to switch based on signal strength -- this is great -- except that it effects transmissions where there is a momentary fade, and the radio drops the audio for a few seconds. side-by-side with my BC246, the BC holds the audio. I understand there is a User adjustment to CC settings that may correct this, but I haven't played with it.
The free software for your computer is actually quite good. It needs to be, as you wouldn't want to do much customization using the radio's limited keyset. Unlike other GRE's, one can have 200 scanlists to play with -- very helpful in dissecting UCAN into manageable service types by transmitter location -- then, unique to the device, are "ScanSets" where you can group all your scanlists for a particular scan. You must use both Lists and Sets to have any output. What's nice is you can do Set selection from the radio w/o much fuss. To me, this is the best part of the package.
DB loads from RR work as advertised, and if one wants to get crazy with big customizations, You are allowed 20 different complete databases on your computer which can be swapped out with eachother by linking with the radio. I found it nice to pick up Trunk Systems when traveling out of state -- and it can be done from the radio when necessary (always the complete system when adding from the SD card in the radio)
Firmware updates work identical to host software updates -- no issues for me --
Conventionals must be added from the PC -- unless we are doing search mode on the radio -- and regardless of when updates are made to the 'real' RR DB, GRE collects and builds a new server library every weekend.
The radio can switch the headphone jack for UNITrunker, but I haven't tried that yet.
Any other questions?
