Not interested in the repeater-just the radios. I fully expect the repeaters to have an output that indicates valid signal (a COS-type output). Otherwise it's a waste of components. >> Yeah...nope-they're just gonna have to live alongside the rest of us >> that can't spend $1000 on a radio...|cP > > The repeaters are far over $1000 for the band module and the > controller, but the user radios (other than the ID-1) are all quite a > bit below $1000, unless you have your heart set on the IC-2820. > > You can buy TWO IC-800H's for just over the price of the signal 2820 > with D-STAR/GPS board (the D-STAR board is included in the price of > the IC-800H) and have true dual-digital receive.

Not enough below for my tastes...Needs to be under $3-400...but I'm not a big Icom fan anyway...last Icom I've had good luck with was an IC-4AT...
