Hi all, I just received my OT1+ SMT, and I am headed out to get parts for it after work. Does anyone know what voltage the LED pins are supplying? I looked at...
Thanks for your suggestions. I had already tried the software DCD as is without any luck. I was able to replace the two 10k resistors with 100k and this...
All outputs are 5 volts. There are no current limiting resistors on the board, so you'll need to select something appropriate for your LEDs. Actually, on one...
I haven't ohmed out the cable yet. I think there are four wires. You can see in the bottom view which pins are present, at least. There's also a button on...
You can try higher value resistors, but at some point the impedance of the ADC input is going to be the limiting factor. There's no harm in leaving the higher...
Another "thought" on this... The pair of 10k ohm resistors (R5 & R10) is to 'bias' the ADC input at mid-point, right? How about INSTEAD of increasing the...
... The Alinco '580 uses the same wiring as early Icom HT's. Also, the Opentracker uses same connections as TinyTrack. Cables and diagrams are available from...
Yeah, that ought to keep the proper bias, though it's going to be a little uglier to implement. I think it ought to work anyway with software DCD off, if the...
Touche...I didn't look at HOW R5 and R10 are placed on the OT1+ board but, now that I have, it doesn't look TOO bad. It looks like the end AWAY from the...
Yeah, I'm trying to avoid making more PCB changes unless there are some real benefits to it. If I can get low audio level support with firmware tweaks, I'd...
Thanks. I was hoping to build the cables myself. I'll figure it out.... _____ From: opentracker@yahoogroups.com [mailto:opentracker@yahoogroups.com] On Behalf...
Hi Group I've just built a new OT+ & it worked well except for a problem where it would transmit every second with the GPS connected with no fix. Anyway, I...
... That happened to me 3 hrs ago, the problem was due to low voltage. Check the voltage feeding the regulator and out of the regulator. ... - check voltage...
Steve, Configs saved in versions of otwincfg PRIOR to this latest version (Built 7/22/2007) are NOT compatible with this version. I'm surprised that it loaded...
I'm using the OT+ with a Magellan SporTrak Color and it works as well as my old TinyTrak for sending APRS data, but my GPS isn't receiving any of the waypoint...
I thought that the Magellans could handle the GPWPL waypoint format, but apparently it needs to be in the proprietary PMGNWPL format. Let me see if I can get...
So I take it the firmware worked? Does the 'APRS' text show up in the comment? I may in the future add limited support for comment text and maybe a couple of...
It sure did. I loaded it up and within a few seconds there were waypoints in my GPS. The APRS text does in fact show in the comment field, and from what I can...
Thanks for the replys. Turns out low voltage is the problem, it just happened to become a problem with the new firmware load. I normally run my OT from 10.5v &...
What was the voltage at the regulator output? It should be fine down to at least 6.7 volts, and the voltage requirements should be exactly the same as the...
I know Garmins track just fine - I chased a balloon for 150 miles that way - but I didn't try it with a Magellan. On the Tracker2, I spent weeks getting the...
