K3 KRX3 B SET and FREQ ENT

Leigh L. Klotz Jr WA5ZNU

I wanted to set the KRX3 to one frequency and the main RX to another.
So I had the SUB RX set and wanted to set main, so  I used M-V M1 to
recall a frequency for main, but that set SUB RX to some random
frequency I happened to have in VFO B the day I programmed M-V M1.
I thought, no problem I'll use B SET.
So I did B SET FREQ ENT but it doesn't seem to allow direct entry of the
SUB RX.

The M-V behavior isn't unexpected but I was surprised that B SET FREQ
ENT didn't work.

The same applies when scanning. The sub-rx becomes inaccessible.

When "Independence Day" arrives, will there be facilities to scan one
receiver independently of the other, on a different band?

Good point.

Scanning and text decode/display will still be usable only with the
main receiver, initially.

IF output from Sub RX? Re: K3 KRX3 B SET and FREQ ENT

Doug Faunt N6TQS +1-510-655-8604
Since we're on the subject of the sub RX, what would it take to get IF
out from the sub RX in addition to from the main RX?

I'd like to be able to set the VFO B RX frequency with BSET FREQ ENTER.

Thanks for the quick reply, Wayne.  When time permits, the first issue
is to avoid overwriting the sub-rx frequency when a scan memory is
recalled for use by the main rx.
