[Elecraft] K3 + fldigi problem...

[John Ragle]

Does anyone recognize the cause of the following problem?

1. First, the details of hardware/software:

     (a) WIN 7 (32 bit) Dell XPS, on-board sound and also Infrasonic 
Quartet PCI card. Both sound cards are never active at the same time 
(e.g. the on-board sound is shut off in the BIOS when the Infrasonic 
card is being used.)
     (b) SignaLink USB
     (c) K3/100 & P3
     (d) FLDIGI 3.21.9 7/or DigiPan. FLDIGI is run using RigCat and the 
K3.xml file.

     The SignaLink can be run off either sound source. The problem is 
the same with either.
     BPSK31 (e.g.) can be run off either FLDIGI or DigiPan. The problem 
only occurs with FLDIGI, not with DigiPan.

2. The problem:

     (a) Transmission initiates correctly with both FLDIGI and DigiPan.
     (b) When transmission is terminated with FLDIGI, the K3 is left in 
"TX" mode -- that is, the red LED under the Power switch remains on, 
although the SignaLink powers down properly and the PSK idle carrier is 
no longer transmitted.
    (c) Pushing any front panel button on the K3 changes it over to RX mode.
    (d) When transmission is terminated with DigiPan, the K3 changes 
over to RX mode properly.
    (e) In either case, during transmit, things are working OK -- one 
can proceed with a QSO.
