The dpl would allow for direct addressing of specific stations ARES
teams etc. Or that sounds possible.
We have a repeater here that for years has had a dual level squelch
system with a pl on the more sensitive setting but none required if your
signal strength were greater at the repeater site. This is to eliminate
the intermod wipe out on the top of the mountain that plagues any
receiving equipment there with all the TV commercial broadcast and
commercial and private radio services as well. Works very well indeed
and is quite simple.

Oh, well there is not many then. What is the reason for doing both? I
would think it would be one or the other, and PL seems to be more
popular
then DPL. I ahve repeaters around here that not only use a PL, but when
you are listening you don't hear the repeater's hang time, and this is
if
you have your radio set to only unmute when the PL comes on. I know
what
causes this, but in those cases I have my HT set up where you just send
out the PL when you key up. That never made much sense to me to have
the
repeater set up to where you have it set up to mute right after unkeying
because if you are the one transmitting you will only know you've made
the
repeater if you press MON.
