We have started to play around with PSK-31 on HF (40 and 10 meters) for

Bonnie,
Here is my experience with mobile messaging with Pskmail. This was
done on HF NVIS but I believe the concepts are independent of the

Appreciate your comments on RFSM. Not many have tried it. I have found

Rick, we are doing a bit better on speeds with RFSM8000. We sometimes get up
