K3: FM testing going well

[wayne burdick]

We now have FM mode working in the K3, including tone encode on TX with
all tones selectable (by frequency in Hz). Memories will store PL tones
and splits.

I've made a number of contacts on 6 meters, as well as on 2 m using an
Elecraft XV-144 transverter. A nice diversion from HF!

We still have quite a bit of FM-related firmware to complete. We'll
probably have it ready in a couple of weeks. If you have suggestions
for FM features, please send them to me directly.

I'd also like to try 10-m FM. Anyone have suggestions for accessible
10-m repeaters, anywhere in the U.S.? I'll be trying the local
machines, too.

That's great news. My FM filter seems to be stuck in transit somewhere, but hopefully it will arrive by the time the firmware is working!

One suggestion that occurs to me (which you may already have thought of) is have you incorporated two preset levels of FM deviation, for HF and VHF? I used to find that HF rigs transverted to VHF have weak modulation because the deviation level used on HF is lower than on VHF. It's probably less of a problem now that 12.5kHz spacing is used on VHF but when 25kHz spacing was used, with comparably wider filters, the difference was noticeable when compared to dedicated 2m rigs.
