G'Day All, I am trying to get more to grips with all the digital modes to operate. I currently run HRD w DM780 and MFTTY software on my computer (Love HRD)
I have used DM780 in the past but it was just plug-in and see if it ran, which it did and was able to make some contacts. I have since moved into a new house and have not had the time to set the radio shack up. This is now coming together and hopefully should be back on the air in a week or two. I want to understand the digital operation more so I can understand what is happening and how to make contacts correctly. Let me start with what I am seeing when starting. DM780 through the sound card to Kenwood TS-480S/AT, in the data socket. When I start DM780 and look at the screen, waterfall I see the data mode, in this case PSK31 on 14.081.5, but the radio is showing 14.080. I remember when I first was using PSK31 I could see other stations within the window of the waterfall, they could of been on 14.082.5 or 14.080.6 and that I was able to leave the radio freq alone and just click on the other station and then make a contact. What I was interested in, is, should I have moved the radio freq. to pull the station onto the 1.5Khz above the. (Don't know if I explained that correctly) Also there is heaps mentioned about NO ALC, I have set my TS-480S/AT to the requirements for digital mode, and even dropped the input down further. I was still getting some ALC when in TX. No-body said I was producing a bad signal so I don't know if I was TXing right. Should I set the radio up as stated and then drop back the audio out from the soundcard? Think that is about it, thanks in advance for any responces. Regards Kevin, ZL1KFM.
