I am pleased to announce that WXTrak is now available at www.byonics.com
WXTrak is TinyTrak3 designed to receive weather data, and transmit it in
APRS format. It uses the same hardware, cables, and case as TinyTrak3, and
is the same price; it just has different firmware. It is compatible with
Radio Shack WX200, Oregon Scientific WM-918, and Peet Bros weathers
stations.
Byon
PS: I will be at Dayton Hamvention next month, in the APRS booth.
I'll have TinyTrak3s & WXTraks, and hopefully also PICPACs and
PicCons.

Were they stolen?
You can barely get an ancient 10 memory 2 meter rig for that on EBAY.

Must have been. Other than $25-$50 TNC's at hamfests because people are no
longer interested in packet hamfests are usually a wash out. People think
their trash is gold, even a 20+ year old Midland 13-5?? 2M rig goes for
$100. Some people think that $50 off retail for a 10 year old radio is fair
at a hamfest. I'd rather buy state of the art with a guarantee that smoke
will not come out than save a few dollars, even to save 50%.
They must have been stolen or you were looking at the price for the
extention kit. How much are they?? $75 I can see someone selling them for
$150. Yes.. I have seen at plenty of hamfests people selling products for
more than they retail!

Actually, the best way to do this it so make it a stand-alone full
function separate program so that people haev to use another frequency to
make it work. By all means APRS is only for one liner tactical
coordinatioon messaging., not passing traffic.
But sinec APRS does "APRS" so well, it is time for HAM radio to get back
to being able to use PACKET to send the rest of the needed traffic!

Does it use the one-packet-tells-all complete WX format, or require
separate WX and Position packets which are less efficinent, and guarantee
that many users dont get the full report for quite a while...?
Thanks

Subject: KPC 3+ and Motorola Maxtrac Quesion

I have a kpc 3+ that I am trying to connect with a motorola maxtrac 100 2
channel transceiver. This particular radio has a 5 pin accessory connector
on the back of the radio which allows me to get audio from that connector
for the tnc.
For the transmit audio and Ptt I am getting that from the rj-45 mic
connector on the front of the radio.
So far I have got everything to work except for the transmit audio. I have
maxed out and tweaked and adjust the audio transmitted from the kpc-3+ to no
avail. The audio is not high enough for a proper driving of the maxtrac. Or
so it seems.
Has anyone had experience with the maxtrac when using it with a kpc-3 for
aprs use? If so, how did you hook up the tnc to the radio? Did you use the
rj-45 jack or did you open up the radio and hook everything up inside? Is
there any adjustments needing to be made inside the radio itself? What about
adjustments to the tnc?
I am new to aprs. I tried it way back when it first came out and no one was
on in my area so I dropped it. I am now tyring to get this system to work as
it is popular here in the Denver Colorado area.
So any suggestions would be greatly appreciated.
The maxtrac radio works great when using a mic and programmed to normal
voice freqs. So I know the radio works great.
Thanks for any help..
Dave

Dave,
All of my radios are Maxtrac/Radius radios or Maratracs.
I use just the front mic connector for everything....its all there and makes
for a nice set up.
This works on Radius M100, GM300, etc. You can have your volume turned all
the way down, so this it's barely heard...which is the way I like it. You
will have to adjust the tx level audio with the TNC and no need to exceed 3
Khz deviation on the mark or space tones. I normally set to 2.5 khz and
that works fine.

It appears from the documentation like seperate WX and posit (Beacon). I
wish the WXTrakConfig.exe program came with WIDE2-2 as the default instead
of WIDE3-3 and WX Every 10 minutes instead of every 1 minute. Most WX
stations don't need to send WX over a path of WIDE3-3 once a minute, adding
a posit packet after every 3 WX packets, as is the program default.
APRSWXNET (NWS official use of APRS WX) only samples the WX once every 15
minutes so in most cases more frequent packets are only another source of
excess packet collisions, causing reduced throughput for all the other
users.
Generally, I think this could be a great product though. Thanks, Byon.

If its a mobile and if you interface your TNC at the discriminator,
consider adding a PL-100 circuit on receive and turning the volume back up
to normal. You will not hear any packets, but you are available for a
"voice alert" for anyone to call you by voice using PL100.
All D7 and D700 users run voice alert. Its like a free additional
radio monitoring a standard "APRS" voice calling channel.
