Hello Jim,
My mistake, I was testing the upper record and playback buttons not realizing that they recorded samples not audio. I have redone the test with the lower button set and it works perfectly and allows me to play audio samples back over the radio when testing with other stations etc. Sorry about the time waste but on the positive side I learned something from this. The attachment will show what I am calling upper and lower record/playback buttons.
