quick addon. I found something weird by experimenting:

On the filter the offset frequency is marked -0.89. If I set the filter offset to less than -.70 the tuner finds a match on all bands tested. Regarding the mic gain / ALC problem I'll go to a friend with equipment and look at the spectrum. I agree that also with a good peak wattmeter it is not possible to see the spectrum ;-) 73! de Werner OE9FWV -- View this message in context: http://www.nabble.com/K3%3A-two-problems-tp16943980p16953710.html 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.
