Control Channel Only in LTR system
I did something with my 346XT in FreeScan that resulted in the screen flashing: Control Channel Search WITHIN a programmed LTR system. It was the only thing going on, even though I had 7 systems in normal scan mode. I have no idea what I did, and have not been able to duplicate.
However, what I tried was to erase all LCN #'s in a programmed system, and selected C/C only. This did not work as I had hoped(it did not identify anything).
Edit: I found a variation on kayleesdad's suggestion. I simply entered each of 10 custom search ranges with SAME begin and end frequency, hold time=0, delay=2, with C/C only selected.
This DID work!! (Just noticed that is what Gilligan said.) I am not sure this is any better than creating 10 sites with the same freq entered into all 20 LCN positions, as suggested in
