Thank you for all the replies and great information.
I have another question on code selection. Other than 411 being a code used for
open repeater, what is the criteria for picking a DPL code.
Also it looks like PL being preferred to DPL is not RFI specific as I have seen
on frequency lists with PL being used in high RFI locatations.
What do you think about leaving the squelch open and letting the DPL control
the COR.
Thanks again...
The DPL list I found.
