CT-28B Adapter Cable

Two weeks ago my Yaesu FT 70D malfunctioned. After loading the radio with a large list of frequencies, the radio speaker stopped working. I called RT Sys and spoke with Karen. She went beyond the call of duty in helping me determine the the cause of failure.. It turned out that when I was recording a net for training purposes. I used a 2 ring stero jack and should have used a 3 ring jack. I appreciate the high level of support Karen provided. BTW I love the RT Systems software. It allows one to easily program their radio.
