Since I started using the K3 for PSK-31 contacts, I've noticed that I have to make many fine tuning adjustments during weak signal QSOs. I don't remember having to make as many using the Small Wonder Labs PSK-20 direct conversion receiver. I am using Data-A mode and a SignaLink USB "sound card" to a MacBook Pro running cocoaModem.
There are several possibilities here: * My memory is bad. * The other station is drifting. * The effect is caused by the SignaLink.# * The effect is caused by the K3. # The signaLink is the same one I used with the PSK-20. I have the stock 5ppm TXCO. I try to let the K3 warm up for 10 minutes before serious use, and I have observed the drift after several hours of operation. How do the short-term (5 to 10 minute) drift rates of the two TXCOs compare? I think I need stability to about 1/2 to 1 Hz for the duration of the QSO.
