If I recall correctly that microphone is an electret. You have to set the bias on the mic setting for it to work.
Go to Main:Mic Sel setting. While in that setting hit 2 to turn bias on or off. You may also want to play with sensitivity setting (hi or lo) by hitting 1. See manual p.20. These settings are available for front and rear mikes. -----Original Message----- From: elecraft-boun...@mailman.qth.net [mailto:elecraft-boun...@mailman.qth.net] On Behalf Of Lew Phelps K6LMP Sent: Wednesday, March 31, 2010 4:37 PM To: Donald Wines Cc: 'Elecraft' Subject: Re: [Elecraft] K3: Mike input no longer works. What filter is set? If you have a narrowband filter installed in addition to the stock 2.7K filter, and if you have been working CW/digital modes with a narrowband filter, and if the settings somehow got messed up on the mode-by-mode filter selection, you might be trying to transmit SSB through a narrowband filter. the K3 doesn't like that. lew K6LMP On Mar 31, 2010, at 3:49 PM, Donald Wines wrote: > I haven't been on sideband for several months and this past weekend I > decided to try to pick up a country or three during the contest. > > I switched the K3 over to USB on 15M, put the Heil Proset on, turned on VOX > and gave a little whistle and nothing happened.
