One thing I noticed is that the TX capture only captures the tx and not the full time between transmissions (I was giving 10 seconds between transmissions all of which is removed of course) I think that makes it a bit worse on the PSK31 for the testing. > Please keep in mind that the RSID signal might act as noise if the RSID > is disabled.

I will issue the recommendation not to use RSID below PSK125 for PSK modes. 73 and commiserations on only managing a silver in the Ice Hockey ;-( Roger G6CKR
