K3 - 2 meters and MARS/CAP

[J. Heide]

I just ordered the 2 meter option and the new wattmeter. On the VHF module, will it be able to work on MARS/CAP frequencies and/or RX outside the ham band? Just curious since the K3 is slowly replacing almost all the other radios in my radio room as more features and options get added.

Th3 K3 seems to do almost everything. I hunt down DX when I'm in the mood, talk with friends on 160 meters, but mostly work my 6 meter repeater on the main VFO and listen to 910 KNEW on the sub receiver.

Not currently. It covers 144-148 MHz, all modes.

What frequencies ranges are needed for 2M MARS/CAP?

Well, the Mars mod for an ICOM 7000 gives 118-173MHz tx coverage.
The Mars mod for the ICOM 91AD handheld gives 137 to 174 MHz tx coverage.
The Mars mod for the ICOM 746PRO gives 108-174 Mhz tx coverage.

Of course the RX coverage is at least as large as the tx coverage.

Now, this is what the most popular current ICOM radios provide after the MARs MOD.
I think the AM Air Band used by aircraft and airports is 108 to 137, so for MARS 137 to 174 would do very well.

However, what is "needed" is probably less.

I find that in my area, MARS tries to keep their VHF frequencies close to the 2M ham band - probably so that existing 2m antennas will function.  However, I know of DHS emcom frequencies that are considerably further away from the 2m ham band.

My two cents,
Hope it helps.
