The point I was trying to make in my initial post is that there is no way to get RX1 audio to Demod #1 and RX2 audio to Demod #2 using VAC. I was thinking about keeping everything "internal" - that is to say using only my 5000A and computer. No extra wires or sound interfaces.
Actually I wasn't trying to accomplish SO2R. My brain is old and slow and I have enough trouble working one radio at a time. What I was trying to do was use N1MM + MMTTY as the main radio interface plus a second instance of MMTTY that was just listening on RX2 to the same signal as on RX1 but using a different antenna on RX2. The idea was to get a little space diversity and hopefully what one RX can't hear the other can. It did not take long to figure out that there is no way that I could see to do this. Dudley's suggestion about hardwiring the second demodulator has at least one problem I ran across. I got out my DXP38 demodulator and connected it to the Flex using the line out/line in/PTT jacks. Then I started an instance of MMTTY running using VAC as the interface. The idea here was to listen to the same signal on the same antenna with two demodulators. Sometimes one will be a little better than the other and might save a contact from being lost. I forget which way it was but one of the audio outputs dropped too low to use when VAC was active. There was some interaction between VAC and the line out audio level. So that approach will not work either. It looks like the only way to do any of this is to follow Dudley's suggestion - use the stereo output, split the RX1 audio from the RX2 audio in PSDR and route the audio channels back into sound cards (or your DXP38). Lots of extra wires. So, in addition to all the other comments about antennas and keying considerations I would request one more: The ability to connect via VAC to each of the RX audio outputs. 73, Mark K5XH _______________________________________________ FlexRadio Systems Mailing List [email protected] http://mail.flex-radio.biz/mailman/listinfo/flexradio_flex-radio.biz Archives: http://www.mail-archive.com/flexradio%40flex-radio.biz/ Knowledge Base: http://kc.flex-radio.com/ Homepage: http://www.flex-radio.com/ Message delivered to [email protected]
