What is the difference between the OT version 4 vs. OT1x? Most of the pictures of new OT prototypes show the DB9 connectors with locking DB9 connectors. Is...
The Rev 4 kits don't come with locking connectors yet. It's going to be at least a couple of weeks before I've got cases ready. The OT1x has locking ...
I must have been looking the other way when this one came out... One thing that tends to happen with email and other such things on the web is that people fail...
... The real question is what has he granted a license TO? APRSdos? That's fine - copyright law says it's his, and he can add license terms to its use that...
It's something I'll be looking at in the future, but it's not a simple thing to implement. I've been more interested in using bluetooth to communicate with a...
Depends on what exactly it needs to detect that it's connected. I've used a firmware tweak in the past to activate certain GPS receivers - it just changes the...
I am having what appears to be RF problems with my tracker. I built a self contained tracker in a small rubbermaid container. With the parts spread out a...
Ferrites are always a good idea. I don't have any listed on the store (was hoping to find some that'd fit in the DB9 shells) but I've got a couple small bags...
I have a couple of Rockwell Jupiter GPS engines. The serial output is TTL and I have built an interface board to do the TTL to RS232 conversion but it doubles...
Sure, check the schematic. It varies a bit depending on which version you have, but there's a transistor and pull-up resistor that serve as a buffer/inverter....
I'm going to be showing off OpenTracker stuff at Dayton this year, in booths 213-214. I've got 16' of backdrop space to do something with, and I'm hoping to...

I'm new to this as well, and do have a bias (Scott is my brother, so the bias can go both ways!), but here is some of my basic understanding. Physically and...
I vote for better and different. A sister who claims her brother means that you are both better and different as well. I got my first OT kit Monday and got it...
Here's my comparison page - it was getting a little out of date, but with the exception of the revision 4 changes and the TT3+, I think it's up to date now. ...
... Right, revision 4 has a larger regulator - not as big as the OT1x or the TT3+, but plenty big enough for a Deluo or GPS 18. I ran one for a week solid at...
... That shouldn't be taken to mean that internally they're the same - you can't swap chips between the two. It's the external connections that are the same,...

Scott, i think you're a blessing to us APRS users with your company and products. You are smart, candid, and support what you say and produce. Customer...
Hey now, I can assure you Scott's products are clean and you're not going to pick up any of that from this forum! Scott does swear that it's not his boards...
