The other issue with the SLUSB audio level setting is that if you use a program like DM780 to watch PSK (several conversations at once) then click on one to use, the actual tones used will change. The audio drive at 1KHz will be different than if you select 1.8KHz so the ALC response may (likely will) be different. Using the native PSK of the K line bypasses this issue but denies your ability to see multiple conversations at once (hoping HRD adds PSK in addition to the FSK they've promised).
As for keeping PSK at the 'standard' 25 watts, sometimes I just don't bother making the change in power from my standard 100 watts. If you're running cleanly (not driving so hard as to create IMD), there is no way the other station can tell what your power setting is. The difference between 3-6db of actual power compared to the same amount of antenna gain is negligible; the signal strength will be the same to the other station. If I had more than a simple wire antenna, I might think differently. If the link appears strong, I reduce power, when I remember. PSK is cool that it work pretty well near the noise floor, where power can help. 73 es Merry Christmas, Rick wa6nhc K3, P3, KPA500, KAT500 -----Original Message----- From: Jim Bennett Looks like I misspoke when I said I could leave the K3's PWR set at 90 and adjust the RF output via the SLUSB. Doesn't quite work that way! RF power out stays up in the stratosphere (PSK31 speaking, anyway) so I really do have to set the K3 to about 25-30 watts out on the K3 and adjust the ALC via the SLUSB. Still, it does seem to work pretty well.
