I'm having problems with PSK (and other digital modes) on my K2. CW and SSB seem okay.
Rig ------ K2/100, KSB2, power set to 20 watts. RTTY (Reverse) for PSK. MFJ-941E Versatuner to a Carolina Windom about 35 ft in the air. SignaLink USB into an Acer Aspire One running Win XP (SP3) On 80/75 meters, I can get a 1.2:1 SWR. CW and SSB look good (good forward power reading on the MFJ). However, with PSK, the best I can get is 5 watts forward showing on the MFJ, but it needs 5 bars of ALC on the K2. With 1 bar of ALC I get about 3 watts out according to MFJ. On 40 meters, I can get a 1.0:1 SWR. CW and SSB look good, and I can get about 8 watts out on PSK with 5 bars of ALC, and about 5 watts with 1 bar. 30 meters is about the same, but with a few more watts, on 20 meters it's still a few more, etc. CW and SSB are good on all the bands. I also tried PSK using SSB (USB) rather than RTTY (Reverse) and got the same results. Anybody have any suggestions about where I should start looking to see what the problem is? Thanks.
