[Elecraft] PSK31 neophyte needs help please!

[Julie Royster]

I have made good progress with PSK31 , and thanks especially to David Moes
and Bill Frantz for taking time to help!

I switched to fldigi and have made one QSO so it is transmitting and
receiving using the elecraft USB to RS232 cable.

What do I do to enable fldigi to read the frequency from the K3?  David
mentions the Hamlib file. does that work through the Elecraft cable? (I did
not plug in the PTT part of the SignaLink cable because I have footpedals
for me & Larry in the rear PTT of the K3.)  I guess if needed I could split
the PTT input.

Would you ever change bands from the computer using fldigi, or do you do
that manually on the K3?

Hoping everyone had a restful Thanksgiving!
