[Elecraft] K3 HRD/DM780 PSK31 problem

[Twan at pa0kv.nl]

Problem solved! Tnx for all the responses.

After lots of trail&error (only errors) I fired up my TR7 and hooked it 
up to my PC.

SAME problem. But I did get one QRZ! So they did hear me.

A wild guess. I replace the sound card in my PC.     FIXED!! :-)

The line out of the other card is damaged and gives a distorted signal.

>> Hi!
>> I'm having troubles with transmitting PSK31.
>> Normal setup which worked perfectly for several years.
>> Setup: K3/100, HRD/DM780, separate sound card line-in/line-out to K3
>> line-out/line-in.
>> PTT control by HRD, K3 VOX ON and K3 MIC SELECT on LINE-IN.
>>
>> For several day I can't make a QSO.  I receive perfectly but when I call, no
>> answer.
>> Also calling CQ on 15m with the band wide open, no answer.
>> The K3 is putting out about 30 watts, antenna (yagi) and SWR are perfect. I
>> also hear the normal sound of transmitting from K3's monitor.
>> It look like I'm receiving and transmitting on different frequencies. In HRD
>> the offset is zero (0).
>> Using USB or DATA A makes no difference.
>>
>> Another thing I noticed; when HRD is finishing a CQ macro, K3's transmitting
>> output drops to zero but PTT stays active.
>> Pressing the XMIT button twice will release PTT and K3 go on receive again.
>> K3 VOX DELAY is zero.
>>
>> Are there any config settings I might messed up? Or hardware issues?
>> I reinstalled HRD/DM780. No effect.
>>
>> CQ CQ CQ....
