That's my mature and considered opinion. I'm probably wrong.
I think you are!!! But PD is just predicting the future!
Now I've looked at your (the OP's) pics on a proper screen I notice they have RX on them. Your radio is receiving signal. When it is receiving it stops scan / DW functions (I don't know which model you have but the MRF57 manuals says:
"if the squelch is set so you can hear a continuous hissing sound the memory scan and tri-watch functions are disabled".
You need to adjust your squelch (if you aren't hearing it make sure you turn the volume up first). If that doesn't solve then willk is already right ;-)
