If you really must do this, you should probably set CONFIG:TX ALC OFF once you've adjusted your power level using the PWR control. Otherwise the ALC system will see the Tx output not being what was requested and will increase the gain, leading to power creep and all sorts of other problems. And a side effect is that when you next request power, you'll get alot more than you asked for because the ALC loop now believes the Tx chain gain is far less than it actually is. The ALC 5 bar level is the level to which all transmit system gains are balanced -- at least those that use any sort of audio as the ultimate source. In the latest Beta code I tried very hard to balance levels so that CONFIG:TXG VCE can be set to 0.0dB. This might have been affecting your power control issues. I did extensive testing with Olivia (125/8 through 2000/64) and WSPR to be sure the power levels are as requested and stable. At least on my K3, they seem to be. 73, Lyle KK7P _______________________________________________ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.
