I use a Commander HF 2500 with vox operation and the K3 and amp work fine here. I also don't use ALC but I watch to be sure I don't over drive the amp so as to exceed the permissible grid current.

I just key the amp with the K3 and did not have to worry about time delays, etc. I have NEVER used ALC with any rig.

I can't seem to get the amp working with the K3. I have previously used the amp with the 480HX, 1000MP and 706 MIIG. I am using the key out circuit on the back which does activate the relay in the amp but when I release the ptt, the amp stays in transmit and will not release. Before I did use the ALC circuit with the amp but I have been told I do not need to use an ALC circuit with the K3. Do I need a separate t/r relay between the radio and the amp? Is there some other menu item I have overlooked? Any help will be appreciated. 73, Richard N4WDU -- View this message in context: http://n2.nabble.com/Problems-using-a-QRO-amp-with-the-K3-tp524929p524929.ht ml Sent from the Elecraft mailing list archive at Nabble.com. _______________________________________________ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.
