At the time the 2800 was one of the best dual band mobiles and it's still good today, with its large colour LCD display. It's 2 separate radios (one for 2 and one for 70) rather than a dual band transmitter with 2 wide receivers like you would get today in a dual bander. Not much use if you wanted to leave it transmitting APRS on 144.800 while you scanned other channels on 145 MHz.
Also the front panel was never meant to be joined on to the main body of the radio, but hidden away somewhere in the car, but there's one small problem - the microphone socket is on the "black box" so you would also need a very long mic cable.
I had the 2800 at home as my main VHF/UHF from 2000 to 2004, then I got the FT-8900, so it sat doing nothing till I had in the car from 2006 - 2008 (replaced by the 8900). Then it was put away until now. Outside the amateur bands, receive sensitivity is as good as the IC-7000 and better than the FT-8900.

I had an Opera beacon transmitting last night on 7.038 and was received by RW3ADB and K4RKM.
Ordered a USB TV tuner which uses the RTL2832U chip, so it's compatible with SDR# software defined radio. Now waiting to see just how good or bad a £6.51 dongle will work as a communications receiver. I know they're meant to be about 40KHz off frequency (which wouldn't matter for a TV tuner).
