I just dismantled a Cidco Mailstation 250 after giving up on hacking it's mail settings away from it's locked down state (another story). I looked inside and...
Does GODA mean anything? GDP-003 94V-0 This would be a sweet display to use. As one user pointed out it may be too much for the PIC as far as interface...
I don't know how practicable it is, but for us Brits, having a display in the local National Grid Reference (Ordinance Survey Grid Reference), rather than...
I'm having limited success... I dropped a 18F252 into the slot and managed to get it programmed through J6 (that was a trial in itself!) with a simple test...
That's it! I'm migrated to 18F252 now. I had two troubles along the way... one was a solder joint on my board that kept me from In-Circuit Programming ... the...
This is my last 18F252 related post for a while as I know the majority of PICPACers will be 16F876 based for some time... Just to say that I have successfully...
I had a similar problem with a different project I'm working on (also with a PIC16F876) where the oscillator woudn't run unless I removed the MAX232ACPE from...
I put 1uF Elec tin can type... In the hole in the NE corner of the inner J4 pads for Pin 5 and I passed the lead of the capacitor through the big circular hole...
Ok ... let me see if I got this right. You put a cap across Pin 5 of J4 (which is GND) and Pin 2 of J1 (which is +5V). I'm not sure how that is adding a cap...
If you follow the tracks from J4 they aren't far from the MAX232A. I left the existing C's in place... I effectively just added C5 which is the decoupling...
Alas i could not get the picpac to work with the frmw available, i can only show data from gps or gps simulator attached to the serial port, but nothing from...

Enrico, I've uploaded a file which has been successfully used by Lucio to decode APRS and send the data out at 4800 baud. When we have had problems (and still...
I have a question reguarding the file that was uploaded 3/13 for decoding APRS. Could it be used to to send data to a PC for an IGATE. Receive only. Whats the...
It's just Byon's decode file tweaked for 4800 baud. It is the last simple program that I have and I know it works since Lucio told me it did. I believe he...
I have an intermittent, annoying behaviour that I'm trying to diagnose. I've got the picpac attached to a Yaesu VX-5, with the 2.2K resistor in the connector....
BTW, I have just finished up a bunch of perl code to decod MIC-E packets (for a different project). If someone would like to take it as a model for a picpac...
I have fixed this: it appears that the VX-5 wants a fairly large cap (10 uF) on the MIC line. I don't know a lot about the specifics of a TNC interface, but...
I also have a VX5R which I connect to my PICPAC for ARDF practice. I drive the VX5R from the tone from the MX614. I find that the output of the chip is...
... I've adjusted the picpac's drive pot to about 60% of travel. That seems to work OK. ... Not obviously, but I haven't done real measurements. The problem...
... today ... it ... out ... Make sure you have RX Save turned off. You need this disabled for all APRS type digital traffic. That's Menu Item #14 73 Gavin ...
... Thanks, I had actually remembered that this time. Turns out that I had added to improve the energy detect performance of the MX614 had gotten tweaked and...
I've been running the pic-trak code on my commute for a few days now. I can't seem to get they waypointing feature to work the way I want - I have selected a...
... 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...
