Trunking?

You won't find trunking on a radio like this...it's a scanner, but it isn't a scanner...it's actually a communications receiver. What's the difference, you might ask? They scan slower, and have wider frequency ranges. I own an Icom R10 and an R7100...sure, they scan, but one bank at a time out of ten. However, I agree with Lindsay...ass kickin' *****in radio! :p

Hello,

I find the use of USB interesting. With the disappearance of serial ports on newer laptops this is a great feature. Unfortunely it appears you can not control the radio via USB.

The other item of interest is ICOM has finally broken through that pesky 1.3 GHz barrier. :)

Sounds like a PITA for Linux and Mac users.

Eric - would you mind patching the firmware to fix this? :D Seriously, that's a shame because it's such an easy feature to include.

Hello,

USB support in a device is really fun to program. :(

Another downside of the R20 is the converter that is needed for the serial comms. My Kenwood D-7A uses a mini jack but it is RS-232 levels. My BC250 actually uses a mini-usb jack. It is nice to just use a cable and plug it into the computer.

I also wonder if it is possible to tap the discriminator and with the dual watch have both a control channel and voice channel receiver for trunker in one radio. I was able to do it with the VR-5000 but I am disappointed in the VR-5000 as a receiver.

So far, from what I read, you can link several or all banks together to scan, PLUS it scans at 100 chan/sec on VFO mode. No word yet on speed for memory scan.

if the icom r20 goes into the 3ghz range.. maybe it has a way to pick up video signals.. and poss a port to output to a monitor of some sort?
havent read that much in depth about it.

I do have a icom rc10 and love it.. esp for mil air AM freq (useful near dobbins AFB that i live near, esp with blue angels coming in 2 weeks)

Yeah, I love my ICR10, too. It is good for military monitoring, and it makes a good emergency receiver for shortwave when a telescopic antenna is connected.
The R20 is pricey...but I just downloaded the manual and read what it can do, and it looks like a worthwhile investment

Hello,

Will the Dual Watch work for two frequencies in the same band? I got the impression that one frequency has to be below 174 MHz and the other above 174 MHz (or whatever the dividing point is).
