Thanks for chiming in. I think everyone is about on the same path as I was thinking. The repeater is listed with RX and TX tones listed as being the same. My MXT115 only will only do single tone which should work I think with the way the repeater is listed. I’ll try turning my code off to see if I can pick it up. There is a newer model MXT115 from what I have seen that will do split tones. It is identified by the front panel where my older unit has a usb A, the newer split tone model has a USB C plug in the front.
