Bill, Ian Thanks for the replies. Re: BIAS. I saw the word DYNAMIC on the mic (a Kenwood MC-43S) and a pin out that showed 8V and jumped to the conclusion that bias was needed.
That was seemingly confirmed when I was able to get the mic to work only when I had BIAS on. There could be some confusion because I was dealing with filter tx settings at the same time. I now have FP.L and no bias. 20 meters USB works. I get RF out on the display. On 40 meters LSB I can still hear the mic on the radio but still get no rf out. The K3 Utility under Configuration shows a 2.8 filter TX SSB When I go into CONFIG: FLTX SB FL3 LSB shows. What else could be going on! -----Original Message----- From: Bill NY9H [mailto:[EMAIL PROTECTED] Sent: Tuesday, August 12, 2008 8:59 AM To: Jack Regan Subject: Re: [Elecraft] K3-100 #1433 Will not transmit on 40 meters LSB. the bias should be off for a dynamic element..... could be the bias being on is messing up stuff..... Only an electret requires that bias voltage. bill At 11:52 PM 8/11/2008, you wrote: >The rig works well on all the USB bands. Mic is a Kenwood 600 ohm dynamic >mic. Bias is on.
