[aprssig] [Kenwood_TH-D74] monitering aprs "Proximity/Voice Alert!"

Mon May 20 10:29:40 EDT 2019

I was astounded that of the 100 people in the APRS forum at Dayton only a
handful knew what voice alert was about.

Im going to start calling it PROXIMITY alert, because that is its real
value.  To hear that someone is in range and after that, then make the
call.  So it will be “APRS Proximity/Voice Alert”.

THe way to do APRS in any radio is to have Four memory channels and ALWAYS
keep the volume UP.:

1) (normal) 144.39 with CTCSS 100 for Voice Alert (and in-range detection)

2) (check) 144.39 without CT so you can check the  channel by ear

3) (Silent)  144.39 with CTCSS (private tone for only your friends to call,
otherwise totally silent)

4) (Event) 144.39 +600 for Events where there is a 144.99 input/144.39
output digi

Sorry, I should have written more specific:

PL on voice on 144.390, not on the APRS signal.

Putting a PL tone on it and that APRS still decodes is fascinating to me. I
will be doing that so I do not need to keep the volume on 0.

Bob B recommend we use pl100 on the APRS side, to squelch the modem tones,
yet have a well known voice channel. Makes sense to me. But I've never
heard anyone on .390. Is such use common anywhere in the country (world)?

Also you can put a tone squelch in on recieve aprs will still decode but
you wont hear anything unless they by some odd chance someone has the same
one in on transmit.
