A bit pricey in my book. If I was designing up a board, it would be cheaper
to get a controller and integrate the design onto the board.

Actually, the one I have promoted is 445.925 the lowest of the simplex
voice channels. It is for "APRS and APRS voice coordination"... Thus it
is in the voice part of the band. Using PL like we use for VOICE ALERT,
APRS and voice are compatible for local use.
All other uses of APRS on UHF will probably need to be coordinated
link-by-link, because to get the throughput we need on the LAN-to-LAN
backbones, you need to run each link on a different frequency...

I found an old email in the SIG archives regarding 441.125 as a national
APRS freq. According to the Alabama Frequency Coordinator listing, there
are no *coordinated* repeaters on this freq. in Alabama. Yes, this is in
the Amateur Fast Scan allocation.
Wondering what others have found regarding APRS on 440.
Tnx es 73,

But maybe NOW is the time to attempt to establish a "Nationally" recognized
70cm frequency for LAN use.

Yes, exactly! 445.925, though our definition of LAN must be different. We
-don't- want another 144.39 with all inputs, all outputs, and all cross
area traffic on the one frequency. We only want the INPUT to be on 445.925
so that someone will always be heard. The full time outputs need to be
elsewhere serving local area needs without adjacent area interference...

I sent a subscription request to the APRS Florida list (aprs-fl) back on the
6th but have never heard anything back. Is this list still active?

Well, I'm talking about an EXACT version of 144.390... only on 70cm... BUT
the WAN connections to other LANS should be on a case-by-case basis. 70cm
won't have the coverage of 2m and the interest will make it even more
scarce...
If you put up LANs on a common frequency but then connect these LANs with
WANs, then this would be an interesting network... I'm not real sure about
packet routing through the WAN... how we would want to construct or define
these collections of LANs. I'm sure that this is a very needed addition to
the existing network.
Do you have a .txt file on this, yet?

The second half of the page is all about UHF links in APRS...

Can an APRS WX station also be configured to act as a relay digipeater at
the same time? What would need to be changed? The station is using WinAPRS
2.51.

Being that it has been a LONG while since I used WinAPRS I won't be able to
tell you HOW to do it, but the short answer is yes. I have a stand-alone
weather station that is also a RELAY digipeater.

Aiming for a common frequency on UHF is far too limiting. Any packet
frequency can be used. Use 144.39 to announce the alternate lans.
Smart software, similar to Bobs magic Satellite Tracking version
of Aprsdos, APRSTK, could automatically control radios like the
Kenwoods.

Dumping the inflexible TNC style digis and going to a smart system
like Digi_ned makes inter-digi inter-lan communication trivial.

Is there any legacy 300 baud packet activity (APRS?) on 10 meters? I have
unused ports on a KAM and an unused HR2510 rig. Given the apartment
situation, going to 10.151 makes for more of an antenna issue.
If so, what's the frequency?

I have previously HEARD of such a frequency, but never noticed ANYTHING on
it myself.
It is/was not an "APRS" active frequency; "per se", but a different
"service" (don't recall name).
Surely SOMEONE else will answer you.
I USED to run 1200bps " regular " Packet in Japan on a
NATIONAL Packet frequency of 29.090 with a PL of 88hz.
This is/was, I believe, a " JARL " suggested band plan.
There was USUALLY, SOMETHING/someone on there, and made use of the band up
there, but as YET, NO SUCH operation is allowable on this continent for
that segment of 10M band....seems like quite a WASTE, just like 220Mhz
before Novices were authorized to use IT. I, for ONE, would be VERY
interested in operation on 29Mhz @ 1200bps....Oh well.

It's not my station so I'll have to find out the rest of the particulars.
I'm trying to get some gaps in our mobile coverage between Norfolk and
Omaha, Ne filled and have to do everything via e-mail.
