Subject: [aprssig] Renamed - RJ45 vs DB9
Each to their own... but RJ45 type connectors are far easier to make
than soldering DB9... and the connector uses up lots less space on a PCB
than a DB9.
Every one has their preference... and if everyone was the same it'd be a
boring world. Some of us actually PREFER RJ45 type connections...
BTW... Shielded versions are available... and with the new Power over
Ethernet Spec... getting power over the same cable is going to be
possible in some instances....
Everyone has their own preferences... (mine included) are no better than
anyone else's...

Crip tools are not as expensive as they once were. I have seen them as cheap
as $5 and with DB 9 connectors becoming more expensive and harder to find
it's a good thing. Go to Radio Shack (try a few) and see what they have for
DB9's.. latley all I can get is their Crimp DB9's that I refuse to use.

This was likely been discussed before - I apologize! I am one of the
unfortunate few who purchsed a Kantronics GPS Tracker (KPC3 aand Garmin
GPS35 in a 9612's enclosure). It sure looks like a neat package but looks
can be deceiving! The problems:
1. It remembers where it was first turned on and never changes it's
position reporting.
2. Now that I have taken it off the shelf nd decided to conquer this
little beast - I can't get it to autobaud or get into cmd mode.
Any help is appreciated. Kantronics fails to respond (like they never
heard of the thing. Garmin didn't respond either but at least the GPS25
shows up on their site nd info is available - even though it has been of no
use to me.
I know, "get rid of it and move on/up" but I bought the darn thing new so
there are several dollars involved!

I suggest you do a hard reset, that will get it in to auto baud. Once you
get your baud set it will behave like a regular kpc-3. When doing the
GPS strings remember to put clear at the end or else it will never update
it's gps position. Id read the manual on how to set up the GPS strings
and doing APRS with it.

Larry,
I don't own one but have worked on one that died for a friend of mine. This
unit has a KPC3+ TNC board with the GPS 25 wired directly to it.
He has had two problem over the years. One is that the cable to the GPS
antenna was damaged where it comes out of the case. He wound up replacing
the antenna but I think it could have been fixed by cutting it back. The
other problem was similar to yours. I wound up doing several hard resets
and the problem finally went away. Yes, I mean several hard resets, the
first and second one did not do it! Don't ask me why but once I got the TNC
to respond properly again, it began to work just fine and has worked for
about a year now without any further problems.
Combining the two units into one box was a bad idea since as you found out,
neither Kantronics nor Garmin takes any ownership to any problems. Each
company tells you to contact the other one. I think if you keep playing
with it, you will succeed in getting it to come alive.
Good luck,

I really don't see the problem. I wired up a DB9 to RJ11 for my
digitraveler and I'm sure the RJ11 side took me less time. And I'm pretty
good with a soldering iron. Crimping sets aren't that expensive, and it's
easy to do. Just make sure you've got all the conductors lined up and cut
off evenly before you slide them in, and make sure they go all the way in
before crimping. The jacks are cheap, easy to install, compact, and
lightweight. I'll probably be using them in the next OpenTracker version.

It was busy. I heard many other stations on PCsat.
I made it again on Saturday with only a 1/4 wave on my Suburban.

Agree on the low cost and ease of use of RJ-45, but one point lost was
wa8lmf made was the dual or tripling up of the socket. I think the device
in question had GPS, power and radio interface on a single socket.
The manufacturer did that to save money as well, but it is really cost
shifting, and cost shifting with a multiplication factor. Lets say I want
the device to disconnect from each device. I'd design a device that has a
socket for each device. Three 0.25 RJ-45 sockets. Then I'd use three 0.10
RJ plugs to connect each of my devices.
But to do it with a tripled up cable, I'd need to make a break out cable,
which would end up costing the end user at least 0.85 more, ugly and a pain
to make.
It is just bad form to triple up a cable like that. Clearly, if the
manufacturer was selling a complete system that they had to install, they
wouldn't have done it like that.

Why not set your radio to the regluar/normal APRS freq while driving, and
have the PCSAT freq set to be the PRIORITY channel ?; that's what I do
sometimes.

Subject: Earthquake - N1VG IGATE down

The N1VG IGATE in Santa Maria is down due to earthquake-related power
failure. Actually, the rack should have about an hour of battery power,
but most likely the DSL connection went down. E-mail's down as well.
Not sure of local digi status - 145.14 voice repeater is down. N6CP-1
looks to be up, so is K6SYV-10 (getting IGATE through KF6HJO), KD6DSI-5
looks like it's down. There's speculation here that the Diablo Canyon
nuclear plant may have shut down, which would account for most of those
failures. I have no RX capability here at work, so I can't check local
traffic directly.
Cell phones are mostly working again. We've got a few downed power lines
here on the base, but no apparent structural damage.
Until my home email's up again, I can be reached (hopefully) at
scott.miller@vandenberg.af.mil.

Power's been restored and everything's working here again. The IGATE
server came back up on its own, but the firewall didn't. KVM switch froze,
too. Other than a panel falling off the VAX-6000 everything's OK
physically. All non-critical systems are shut down to conserve backup
power in case it goes out again.

The RJ- series connectors may be great from the manufacturing point of view
but are a major headache from the users' standpoint.
I am talking about making custom cable asemblies AT HOME for devices with
RJ45 connectors. Trying to get the multiple stranded individual
conductors in a shielded cable like a mic cord, or a two-conductor+shield
stereo patch cable for a soundcard interface, or just about anything except
flat telephone wire into an RJ plug, and then reliably crimped, is a pain
without industrial tooling. The braided shield wire is especially
difficult to deal with. (I usually solder a short length of solid #24
phone wire to the braid and crimp on that.)
The problem is especially acute with devices like TNCs that get interfaced
to an almost infinite variety of connectors on the other (radio) end (8-pin
round "CBC-series" mic plugs, 7-, 8- and 13- pin DIN plugs, 6- and 8- pin
RJ connectors, 6-pin MiniDINs, etc) etc. This virtually guarantees that
the end user is going to have to fabricate cable harnesses at home. Not
to mention the forked cable assemblies for combo radio/GPS hookups with
wierd connectors for the GPS side.
