Jim,

I have the AX5043 working on 145.835. It ranges correctly and receives packets. At least it receives them some of the time. It seems to be quite deaf compared to wje it was working on 436.8, which is my 70cm RX frequency. That receives every packet without error.

I had the same issue on 70cms until you told me to tweak the frequency. But with the TXCO it seems to be right on frequency. I ran a test to TX on the RX frequency and it seems to be correct according to my TinySA.

thoughts?
