hsmith61 I wish I could help. Like you I downloaded EasyPal to try and decode Dr. Benway's broadcast the other night. I had the same problems, all I did was close and restart the program and I started to get the decode. I just opened the program again and I got the same messages that you got I also got one telling me that EasyPal was in the basic mode. Again not sure what I did to get it to work, I later Googled EasyPal frequencies and tried to decode something but got nothing.

I struggled trying to decode Undercover Radio from last night (3/3/2013) but could not get anything to decode. I tried this morning on 7173 LSB with the hams, and got it to work, but the signal were stronger. It does seem to be rather sensitive to signal level and SNR.

I went back to the SDR recordings of Undercover's 2/25 transmissions, and it was the same. I could get the IO and Time markers on the Sync indicator to turn green, and very rarely the Frame, but that was it.

You need to, at a minimum, assign an RX soundcard device to EasyPal.

When you EasyPal, navigate through the menus as such:

Setup -> Setup c/s-soundcard-PTT -> Soundcard

By default it appears EasyPal will try to grab your default Windows recording device (audio input). If you have multiple sound cards, or like me, you have a radio that connects with USB to the computer and thus appears as a sound device, you need to either set this as your default recording device in Windows sound control panel before you run EasyPal, OR you need to instruct EasyPal to use the device that is feeding receive audio into your computer. It sounds more complicated than it really is.

One definite bug in the EasyPal program is that you will get a very cryptic error, and the program will not start, if there is either NO recording device active in Windows or you disable the recording device. I found this out by trying to start EasyPal before I turned my receiver on (which subsequently appears as my default sound device in Windows).

Otherwise the program will work with the defaults to decode EasyPal transmissions. I have good success with it, but a strong signal (SNR) is required for reliable decode.

Thanks for that input . I did that and got rid of the error message for the input sound card . One Q do all the green need to be showing for proper decode. Would think so as i just tried to decode on 7173 and wasn't  a good strong Signal .
