WHY Oh WHY do ham mfrs insist on using these horrible
almost-impossible-to-wire RJ11 phone and RJ45 LAN connectors for general
purpose I/O and mic connections?
It's almost impossible to produce a decent shielded cable assy with one of
these things, or to make a forked cable that branches to two locations such
as the GPS and RADIO connections mentioned above.
Why not a DB-9 (ala Kantronics TNC) or a 8-pin round mic plug connector.
Or best of all that wonderful two-part connector (don't know who makes it
or what it is called) used on Zetron repeater controllers, paging
terminals, etc. It consists of a header with a single in-line row of holes
with setscrews . You stick any kind of stripped wire ends (either single
wires or individual conductors of cable assys) into the holes and tighten
the setscrews. Then the whole header assembly plugs into a recessed pin
field in the back panel of the equipment. Lets you through together
interface cable harnesses almost instantly.

xxxxx euro is about $xxx us. Depends on the day. The dollar is low right
now against the euro.

The tnc looks interesting. One comment, it says it can be used as a
tracker. OK, $xxx vs $xx for a Tiny Trac. This tnc will be very nice to
laptop users that do not have serial ports and PDA's. And yes, Compaq makes
several models of laptops without serial ports. The Emergency Management
Department I volunteer with has 4 of them. Maybe they should see if they
could find a US distributor.
PM 6.0 and Winaprs. I ran in to Keith over the summer. He said they planned
to support it, but did not give a date.

You might consider putting Linux/Xastir on there instead, and running
Shapefile format maps. It should still run ok on a 486. I'd
recommend starting with ZipSlack (a subdirectory on the Slackware
site), and then adding some X11 disks and then shapelib. That'll
give you nicely detailed street maps, that should be relatively
fast.

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...

Very likely on cost grounds and ease of production (an RJ45 socket is easier
to mount than a DB9).
I certainly agree that they are bad news for the hobbyist (is that not the
market they are selling into?!) unless you have a local friendly network
engineer who can make the leads up for you.
Most manufacturers will sell you an additional lead to convert to the more
common 8 way audio (or DB9 depending on the lead function), but this is a
con!

Is there any other way to check out results? Last night I think I got
digi'ed and I know that I heard a packet or two come back between 8-10am but
I don't see my callsign. I did not have a chance to look at the results
till' now since I am on the road and just got in the hotel.
Nice thing was that 2 times during my trip where I was out of all APRS
coverage I did happen to have a PCsat pass or two. When I heard no .39
activity I switched to the sat channel, I checked .39 here and there for
coverage but if I heard nothing I stayed on the other channel.

Worked fine for me on 2 tries today. Big problem was that I kept forgetting
about Voice alert. I left SE Florida yesterday morning and decided to sleep
for a few hours in Rocky Mount NC just so I could visit HRO in VA this
morning. Upon exiting the Balt/Wash Tunnel I saw WB4APR on the map and upon
calling him he replied. Could not do a QSO since I was a bit far for 52 and
was running a Motorola rig, tough to reprogram while driving!
A few hours later I called a N2 station in South NJ that was nearby but soon
I was out of range for simplex, he also responded to the voice alert. The
idea works fine, most of the trip from FL to NJ no false PL'ed packets that
I noticed. I did run open squelch a few times while in the Carolinas trying
to figure out why digi's a few miles away could not hear me but others
almost 1/2 a state away could! Other than that a quiet trip with no brapps
in the background.

I agree fully! I would much rather break out my crimping tool than heat up
the soldering iron. 3 seconds versus a few minutes connecting a connection
to a wireset is a big advantage to me, IMO.
