I found a most recent article in QEX on controlled envelope SSB most
interesting in that it could yield close to 3dB in power by eliminating the
overshoots in filters, etc. I know contesters are always looking for the next

I'm wondering what external station controller you are using. I'm using a

Good thought, Phil. Actually I have an external speaker plugged in, a NCS 8
ohm, and I did try unplugging the speaker to see what would happen. Same
story - no change in hash. The answer has got to be in the cable itself. If
it's verified with a solution, I can actually have another cable made.
Hello:
I've noticed some audio hash on my SSB signal on 6M only when the PA relay

disappears when I use a Kenwood hand mike direct to the K3.

As a follow up, I doubt it's the Goldline mic/cable itself, as I get the
same hash with a Heil headset plugged into the switcher.
