Hi All,
I have a modified Philips 828 transceiver which is running on 145.175, the
APRS frequency in Australia.
It is to be set up as an APRS repeater, preferably stand alone. It will be
at a solar site.
What is the latest in available hardware to convert the rig into a stand
alone repeater for APRS at a solar site?
Thanks
Ron Smith

The THD-7 fails miserably at 9600 - the buffer is too small and too slow to
handle any amount of text. This has been thoroughly documented and
discussed here in the past. Yes it'll work for small posit packets, but
not for anything else.

Subject: Cable Modems on HAM bands?

A Cable Modem operates at RF (in a cable TV system).
WHy not simply hook it up to a converter to up/down convert the signal to
a pair of HAM bands and get High data rates on the HAM bands.
This idea came from Ron Parise WA4SIR during a chat around the water
cooler. There's lots we don't know, and maybe someone on the APRS or
AMSAT sigs works in the industry and can fill us in.
Things we assume:
1) Uplink is below 50 MHz, downlink is somewhere in the CATV passband.
2) Since uplink and donwlink are different, then a "repeater" would need
to be installed in the city to tie everyone togther (or a HAM satellite).
This approach at taking a consumer item and modifying it for HAM use has a
certain atttraction, since it gives us an unlimited supply of
cheap hardware on which to build... The ONLY thing we have to build are
the repeaters (or satellite), for all of use users its plug-n-play.
Any experts want to fill in the modem details and the bandwidths and
frequencies?
Bob
Since the uplink (inlink) is low data rate, it could probably fit easily
in the 220 or 440 band somewhere, the downlink (or outlink) might fit in
900 or 1296 somewhere...?

For solar sites, the Kantronics KCP3+ TNC is the no-brainer choice. It has
built-in APRS-specific digipeating "smarts" as a standard feature. Nothing
else comes close for low power consumption -- 9mA (nine milliamps!), even
less with the front panel LEDs disabled. You don't need anything else except
the transceiver and antenna.
By way of comparison:
TNC2 or clone (i.e. MFJ-1270) running UI-DIGI firmware 270mA
AEA PK-232 980mA.
PC running digipeater software 1500-3000mA
(assuming a laptop running on a DC-DC converter - - you will still
need a TNC or soundcard interface if you run the AGW Packet Engine
softmodem)

All I am expecting the d7 to do is send a mic-e once in a while. 9k6 on a
voice channel is not as annoying as 1200baud mic-e bursts.

Presenter at the Square Route Rally, very cool.
Here's the link to my current pictures page.
http://www.urec.net/users/dcreich/pictures.htm
I should have my bike at Marions Saturday night, if you want a closer
look at the tupperware. (^8
Basicly I use a D700, Garmin GPS and an Autocom Intercom.
As far as ABS goes, the BMW Bikes with ABS use special sheilded coil and
plug wires. I tried to get a set, but didn't want to pay the extra
money. As far as the bikes go, BMW invalidates warrenty work for all
kinds of reasons, but I've heard both good and bad stories. I've heard
cases where they've covered things not normally covered under warrenty,
like clutch spline shafts. And I've heard the opposite stories, too.
Your dealer is important here, a good dealer will go to bat for you with
BMWNA. A not-so-good dealer won't.

And it has built-in APRS telemetry, giving you a packet every now and
then with 5 analog values. Nice to know things like:
Battery VOltage
Solar charge current
Battery load current
temperature (ambient)
Termerpture (XMTR)
APRSdos plots these things for you..
etc
See the TELEMTRY.TXT file included in all APRSdos docs...

Gents,
How does this sound, maybe the APRS software GURUS would like to
implement it ?
Half the screen = local area map
Other Half = auto scrolling close in maps.
Just like UI-VIEW has one map now, have two, one fixed and the other
autotracking a car say.
ideas ?

Help!
I cannot get APRS+SA to interact with AGWPE/KIPSS. AGWPE and KIPSS seem to
work OK, but APRS+ does not seem to be able to connect to it.
Any hints?

Are you sure you downloaded the correct file?
You need this: KipSSPE
not: KipSS.
