PSK31 on K3

[David Andrews-3]

When I transmitted PSK31 on a K2, I increased the audio until the ALC just
flickered. The K3 Manual suggests that the mic gain is advanced until 4-7
bars show on the ALC. I thought compression and ALC had to be zero to avoid
excessive bandwidth and distortion? Has the K3 got something the K2 hasn't
in this respect?

In a word, yes.

The K3 manual is providing the correct information for use of PSK31 or
other modes on the K3: CMP set to 0, and MIC or LINE IN adjusted for 4
to 7 bars of ALC.

Enjoy!
