I was trying to work some 40 meter digital this evening but there are stations that have some audio extending down to 7070 which makes it difficult to use digital up at 1500 up from 7071. In fact, for a while PJ2/WK4Y was operating LSB right on 7071.5 which I think would put his passband right over the PSK31/digital mode waterhole.
I was calling CQ in MFSK16 and Frank, K1CRU came back to me from CT. I was only able to copy a small percentage however he was able to copy me 100% because he did not have the interference. We tried switching to Olivia 500/16 but that was worse and copy was barely 10% on my end, but again, 100% on his. I then suggested we try Domino EX 8 which is available in Ham Radio Deluxe/Digital Master 780, but was not able to copy him after that. I would like to hear opinions on other's experiences working through voice splatter? I know that MT-63 can work except that the wider versions can not work as deep in the noise as you find with modes like MFSK16. What have you found that worked and what did not work. 73, Rick, KV9U
