Howdy,
I have been busy coding for months now and have started to put some
scripts down on my web site. This will increase. Hope this inspires
others to have a go also.
Cheers Andy VK4TEC

Subject: Re: 100 HZ PL
From: Ron Gilson WA2WWK
Originally, if a 60HZ power supply was used, 179.9 PL was not recommended
and if a 50HZ power supply was used, 100 PL was also not recommended. This
was because the early decoders were either reed or simple filters which
would respond to both the fundamental and harmonic frequencies. With the
newer generation of decoders, this problem seems to be eliminated. One
local two way shop uses 179.9 exclusively on 20 shop repeaters without
problems.

Subject: Digi-ing?

To anyone with some time to spare:
My friend and I are trying to understand the concept of digi-ing APRS
transmissions. He has a D700. We also have D7's. He set his D700 up to
digi and we sat within 50 feet of his tower and it never seemed to digi
anything.
My question is... What would I have seen if it digi-ed? And I guess I
really don't have a good grasp on what the terms RELAY, WIDE, and all the
variations of those words.
The area my friend lives in need a digi to fill a necessary gap, along an
interstate, but the doco in the manuals and books assumes that one of us
understands the true concept.
If we could understand these functions, I believe the whole APRS experience
would benifit and we could also understand what the folks on the SIG are
talking about sometimes.
Thanks and I realize that these questions are pretty low level, considering
the discussions that show up here, but if I could understand more, I could
progress a lot.

Yeah I read that story, too. I received it through a different mailing
list, too. It would set a really bad precedent if the CBer loses this case
(regardless of the actual interference issue). Only the FCC should be
allowed to enforce FCC regulations regardless of service.
The BPL/PLC industry will make sure their services will not interfere with
consumer appliances. You can safely bet on that. I don't think there's
anything to gain for us if the city would win in this case.
If you read the story carefully you'll notice that the ordinance was
obviously a targeted campaign against this individual. I wonder how many of
the 28 petitioners are on the city counsel.
Off topic? Just imagine it's packet racket interfering with the baby
monitor.

Thanks for the report, did you get any indication what crashed it? I
have been connected to the second.aprs.net internet feed for almost
12 days without a problem.

Search for digis.txt in the original APRSdos docs.
A google search on digis.txt came up with 54 copies out there...

I'm not much of a bleeding edge theorist, and months ago when Bob suggested
APRS Voice Alert it sounded like a good idea. Especially for APRS users
who have the Kenwood mobiles.
As time passed, I have seen discussions on the list about the ALOHA theory,
APRS traffic load on the frequency, inconsiderate digi paths (like around
the world via 80 digi's or more), and numerous other APRS 'breaking edge'
litmus tests.
I've also seen some mention here that a minuscule number APRS users have
actually experienced a Voice Alert contact. Although, a few have admitted
they should have followed good amateur practice and QSY'ed, they did not.
In QST I have seen Amateur's lament about throwing out their callsign on
the National Simplex Calling Frequencies and going unanswered, as well as
calls on local repeaters being answered with silence as well.
I have also read of FCC enforcement actions being initiated against
amateurs for not observing band plans, which I believe someone mentioned
the APRS frequency is recognized in the band plan as a digital data
frequency.
Those of us who have a dedicated Radio & TNC most likely have at least one
other transceiver in the car, house, boat, plane, etc. for voice contacts
and either monitor, or scan, other frequencies. I suspect even the Kenwood
crowd probably has some other frequency set on the 'B' side of the radio
for voice.
Based on the above, Herb & the NW APRS groups idea listing the frequency
monitored in the posit comment seems the most useful and prudent idea.
Most APRS software allows you to view the information about a station of
interest (speed, dir of travel, elevation, last position/packet, status,
weather, posit comment, etc.) and the frequency monitored by that user
seemingly belongs right there as well.
A couple of simple and overlooked benefits come to mind. Mobile APRS
stations can find 'active' or monitored simplex and repeater frequencies in
unfamiliar areas easily; in an emergency, selecting an APRS station nearby
with a frequency listed should, in most cases, be the most direct link to a
911 call to the proper Public Safety agencies.
There are probably other benefits and drawbacks I can't think of offhand.
Yet, while the amount of spectrum we occupy isn't luxurious, do we need to
attempt to cram as many simultaneously different radio activities into use
on one frequency ... to prove we can live with less spectrum?
We, as amateurs, have plenty of 6m, 2m, 220 & 440 mhz simplex and repeater
frequencies going unused for voice at all times of the day and night, but
only one frequency for APRS data that is constantly being utilized.

Yes, this is the best thing to put in your STATUS text... If you stay on
one freq. It can also be very frustrating when you are not on that
frequency and people keep trying to call you there.
In my STATUS text, its easy. I put the frequency I am "always" on. It
says:
"Voice alert PL100".
It is always right and it always works and anyone can always call me there.
BUT it is much better to have the BAND-B freq there as you noted. What I
would like someone to do is to invent a PIC processor attached to the
unused serial port of my D700 mobile that periodocially checks the radio to
see whats on my Band B and then to WRITE that into my STATUS text.
