[Elecraft] K3 DATA A help needed

[Paul Milward]

Hi
I moved my laptop computer offsite for a few hours this morning. On return I 
reconnected the stereo cables from I/O on the K3 to the I/O on the laptop. 
Everything worked flawlessly prior to the move for PSK operation. The rig still 
receives and the laptop still decodes signals...but the Rig will not transmit 
when the software/soundcard is activated. I have the K3 set to DATA A and VOX is 
engaged. I did not change anything on the radio or in the soundcard software. I 
am using DIGIPAN 2.0.
I did contact my ISP this morning prior to moving the laptop offsite. I had an 
issue connecting to the internet and we, the ISP phone tech and I, reworked 
passwords for network access and email. I deleted Temporary Internet files, 
cookies and history at his direction. But no changes were made to sound card 
settings.
Any suggestions? I really want my PSK fix. Any help appreciated.
