... and ... I am looking to improve the receive performance of my PICPACs and thought I might go down a similar route... it then struck me that the bypass...
Gavin, Below is a list of the hardware changes I've made to my PicPac. I have no idea how these changes would affect anyone else's PicPac (proceed at your own...
Mark, A bad day for my experiments yesterday... I seem to have periodic resets/hangs of the PIC... I think the power supply is my next target for further...
Hi Mark, here's another data point in this saga -- I implemented these changes (except for (1) and for (5) used a 10uf cap instead of 100uf) in hopes of...
Gavin, I added the two caps the the ceramic reonator becuase I was at that point in time taking wild stabs in the dark trying to find the cause of my energy...
More experimentation this evening... I set up my TNC-X next to my PICPAC and then took another PICPAC for a walk. The TNX-X and 1st PICPAC had identical...
1200 baud works. Get a copy of the MX614 data sheet from the web (just google for it). I finally got mine to work more or less reliably - one of the things...
... The MX614 is a bell 202 modem. It's 1200 baud only. http://www.datasheetarchive.com/datasheet/pdf/11/115288.html (the download button is at the very bottom...

I'm getting pretty good results now... I have modified the power supply to have 100uF Electrolytic as C8 and a .33uF Tant as C9. This seems to give a nice...
Hi, Im collecting parts to build a pic based packet box (probably like yours). I was just noticing your comments about audio levels. I have not plugged in my...
Just for info, I have a couple pictures in the Photos Section of the case I milled and used for my PICPAC. Its an off-the-shelf RadioShack metal project box....
hi, it will depend on the reciver , some reciever have limiter , some other did not have limiter,. will be easier if you yuse capacitor 10uf/16v. and 50K vr it...
Hello, I am new to the list and my major interest is about getting a good piece of C code that performs decent decoding in order to base subsequent projects on...
The PICPAC decode2/pptest2.c is a good starting point to be found in the documentation/sample code zip at http://www.byonics.com/picpac/ The hardware in a...

Hi Matteo, You are also welcome to convert my code at www.garydion.com under the WhereAVR link. It doesn't share the same hardware as the picpac or TNC-X as I...
Sorry for the OT post, but Gary, that Video overlay is SLICK! Would you be willing to sell an assembled and tested unit? I've been looking for something like...
I haven't used APRS but since I now have a licence I thought I might give it a go... I've got a GPS, a Yaesu VX-5R and a PICPAC... is that all I need to get my...

I have TSIPMONITOR Program from Trimble,but there is no seting for the NMEA Output sentence format......!? May be other way to do that? Thanks, AE6OR...
Hi group Here is an software to make Lassen to talk nmea in 4800 baud http://tuben.lugn.nu/APRS/Lassen_Init.zip It´s my frind Torbjörn and his friend Thomas...
I've decided to sell my PICPAC. I last used it pretty successfully to run PIC-TRAK; it's got the common added capacitors and decodes packets pretty well. I...
I bought this when they first came out and just every got around to working on it. So, after looking at it for quite some time, I decided it was time for us...
