Mike, Thanks for pointing that out - I had completely forgotten about that option. I guess it's time I printed out a new copy of the manual! Of course, that changes the answer to James' question #2; if you want the LINE output to be a clone of the headphones output, set CONFIG:LIN OUT to =PHONES.
With CONFIG:LIN OUT =PHONES, when the subRX is off, the main RX is in both channels. This setting seems tailor-made for James' situation (listening to speakers through a sound card). For digital modes, as Joe has pointed out, when SUB is on, you use the two channels to feed two independent copies of MMTTY (or other software). You do not want any mixing of the two signals. Also, you do not want the volume control to affect the audio level going into the decoder. If you use the audio pitch as a tuning aid, you want the ability to turn the audio down or to change the balance between the two channels without interrupting the ongoing decoding of both signals. When SUB is off, you only use (or need) one channel in the sound card. The right channel waterfall just goes black when the sub RX is off. You can use two different decoding algorithms on a single signal by running two (or more) independent decoding programs (e.g. two or more separate copies of MMTTY using different profiles) from a single channel in the sound card. 73, Rich VE3KI NF4L wrote: > Re: point #2. > > I don't have a sub rx, so it's never been a problem for me, but I'm thinking > of > adding one.

Does that give you a level control using the AF knob? > ______________________________________________________________ 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
