Have you tried setting it as a stationary GPS so it's no longer waiting for a lock? Those wires might have damaged the GPS. I realize that it not decoding...
Did you download the firmware file manually or using the 'web' button? If it was manual, can you send me a copy off-list? A few people have reported that bug...
... Yes, I've been over the code looking for possible problems but it's still a possibility. If you can make a note of the callsign and time at least, that...
I was using the otusb plugged into a 5v usb adapter plug on my vehicle and the power flashed off and on quickly, now the otusb will not light up with either...
It would be very nice if this issue would be solved: we have currently six digis that, frequently, stops digipeating or stops also the Beacon... 73 de Guido,...
Chris, Thanks for the ideas. I'm not able to make any setting changes the way it is now. I have access to another GPS and can try that in a day or two. I...

The latest beta firmware version includes a safe mode - if you mess up your configuration, you can still force it back to defaults and access it via USB. Scott...
Its not getting 5 volts with the usb powering it or with 12v. The odd thing is with 12v power source the voltage regulator isn't getting 12v either. Looks...

... It's not just that it takes a lot of time, it's also that with phone support I make less efficient use of the time I've got. You'll notice I answer a lot...
What's the 12v power source? If it's one of our tracker cables with a cigarette lighter, unscrew the tip and check that the fuse is OK. The left side of the...

Using your 12v cigarette lighter adapter into a 12v battery: I get 12 v in from the DB-9 U1 registers no voltage difference between the CN4 8 pin (ground) and ...
some further testing shows that D3 has 12v in and nothing out, so that is probably the culprit, although c3 seems to not be functioning either (no voltage...

A small solar panel would do the trick! I have a panel on my truck and it keeps my auxiliary battery charged. My radios run off the battery and do not run off...
Thanks for the responses. Actually, a tracker drawing negative current would be ideal! Sadly, the laws of physics prohibit such a tracker. I wasn't aware that...
Hi, ... Have you put an ammeter on it to check what it's drawing? The GPS receiver will probably draw around 50 mA, and an OT1m maybe around 12 mA. For...
