"Raspy" is often the description given a signal from a K2 that is sitting too close to a transformer so the a-c magnetic field modulates the VCO. If you have a power supply, desk lamp with a transformer built in, or any other transformer operated device nearby, try turning it off and see if your signal clears up.
If so, there's a mod for the K2 that will dramatically improve its resistance to magnetic field effects. See www.elecraft.com for details. About the power control, are you expecting it to go to work before your transmit? It won't! The power control sets the "requested" output. The actual output doesn't change until you transmit again, and transmit long enough for the power monitor to note the actual output and adjust the circuit to match the "requested" level you set with the POWER control. It's not uncommon for ops to turn on a rig and notice that even though it's been in receive for half an hour, when the hit the key the power stays at zero for the first dash or several dits, depending upon the keying speed. That's because the power control circuits are only then getting some RF to work with to set the actual power output correctly.

What I have found is that I was wrong in believing the CW was OK - its not - it has a very raspy signal to it. So I will try to track that down first. I am confused about the behaviour of U2 on the SSB board - it seems to take a long time to ramp up if it is setting the PWR level. However, before I worry much more about this one, I'll try and track down my raspy CW signal first. 73 Paul _______________________________________________ Elecraft mailing list Post to: [email protected] You must be a subscriber to post to the list.
