[digitalradio] New to SSTV

I just downloaded and installed EasyPal and after a few hours have the code for PTT figured out and have it working from what I can tell on my dummy load. Is there anyone on the group that would meet me on a frequency so I could test it out over the air tonight? Bob AD5VJ

Bob. It has been a couple of years since I have used it but will be glad to try a sked. You can also tune to 14233 and usually find signals to decode.We can use the digitalradio sked page to coordinate things if needed. Andy K3UK On Sat, Aug 8, 2009 at 2:17 AM, AD5VJ Bobrt...@sbcglobal.net
