Found the problem. Immediately adjacent to U2 (volt reg) is the stencil on the board indicating that U2 goes there. Within the "U2" stencil appears to be a...
Hey Scott, On the OT1m, what are the jumper options for JP2, and JP6? I read where I need to pull the jumper on JP1 for the OT1m to properly control my mobile...

I am assembling an OT1x. The pictures show pin header JP1 on the same side of the board as the processor and other components. The instructions I received...
Hello, After a search for the following did not produce the answers I thought I would post. Anyone willing to share the wiring for the OpenTracker and the ...
... The Opentracker has the same pinout as the Kantronics KPC series, so if you find a pinout for those TNCs with your radios, the Opentracker is the same. -- ...
The headers get inserted from the bottom, so that the plastic spacer part is underneath the board. Otherwise the case won't close right. I'm still in Florida...
Thanks! When I finally inserted the long end of the header first ("..so that the plastic spacer part is underneath the board.."), everything made sense....

... It's supposed to. The transmit delay is the delay from PTT until the _data_ starts going through, but a TNC will typically send AX.25 flag characters or...
I'm using a Evermore GM-305 GPS mouse receiver. It is very similar to the Deluo versions. The available NEMA sentences are GGA, GSA, GSV, GLL, RMC, VTG....

Hi Fellas, Need some help with my OT-1m with the jumper settings. Specifically JP1, 2, 3, 4, & 5. I am using along with the OT-1m an Icom-2AT and 1-Wire AAG...
When you are tracking a moving object, aprspoint will record all its positions on the map, and optionally connect them with lines to form a track. If you are...
Not a testpoint, probably a via - it's there to connect traces on the top to traces on the bottom. There was an early version with a via directly under the...
