When I measured the transmit IMD from my K3 (using a dummy load and a directional coupler that feeds into a second rig's receiver), I found that the best transmit IMD for a PSK31 signal occurred when the 5 bar just turns on, but is solid and not flickering. 73 Chen, W7AY __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
Re: [Elecraft] [Elecraft K3] ALC readout
Four solid bars with a barely flickering 5th. The first four bars are a VU system of sorts. Once the 5th bar more than flickers occasionally your getting some ALC action and need to back off a skosh (scientific term of the day).

Re: [Elecraft] [Elecraft K3] ALC readout
Dave, Lyle's the designer and he has stated that for data modes, 4 bars with the 5th bar flickering is correct. The 5th bar indicates the onset of ALC. For voice modes, go up until the 7th bar flickers (turn off compression first). After setting the audio level, then add back compression as desired. These steps can be done in TX TEST so no RF is transmitted. 73, Don W3FPR On 2/2/2011 12:33 PM, David Robertson wrote: > Greetings everyone, > I am a bit confused about the exact number of bars in the ALC meter that is > used for VU.
