> monitoring the APRStt simplex channel (147.51). Soon your TH78
Whoa! Where did this frequency selection come from?
It's not a 20k spaced channel.
Both 147.50 and 147.52 are in use in my state - even way out here in
EL17HQ I hear traffic on both, often. It is more used in the Houston and
San Antonio area. With some other problems, (see below) 147.50 may be
unusable due to D-Star.
You should at least pick a frequency which is OK with 15k and 20k band
Also be aware, there is a proposal here in TX to use these pairs for
D-Star 2m repeaters:
I do not think this is a good idea, and it is not yet in the standards;
yet there are a few (3 that I am aware of, as a non-D-Star user) systems
already on the air on some of these frequencies. So, in TX, the D-Star
useage is reducing the available 2m simplex channels for FM voice.
Further details here:
Note that this proposal was NOT passed at the August 08 Society meeting.
But it is still under consideration.
