Since two weeks I have a new Mikro-Trak 300. I have problems to decode my signal. Only a very few stations are able to pick up my packets. In my transceiver I...
I am building a few low-loss relay antenna switches for a client ( To use two radios with one antenna for a Balloon application) These will have board mounted...
Jim, I am going to post an E-mail response I sent to an off-line E-mailer to provide more info on the switch below: My relay board is designed to have a very...
Allen, thanks for the information. In my vehicle I do not run more that 5 watts. If 5 watts won't do what I want then that's too bad. I would like to know...

Hello, This email message is a notification to let you know that a file has been uploaded to the Files area of the MicroTrak group. File : /RF...
I have posted a photo in the files section showing where I installed 4700 PF chip capacitors on a Micro-Trak 8000 to prevent RF overload from causing the PIC...

I received my Micro-Track 8000 today. Beatiful workmanship. I intend to use it for APRS. What is pin 13 En for? I would like to switch power for 1, 2, 5, and 8...
John, The EN pin can be set to go high any number of seconds before a transmission occurs. In the regular TinyTrak it is used to switch on a radio or GPS to ...
Hi all. I just fired up my 300 ver1.4 for the first time. It's first transmission works, but then I don't decode any packets after that. I can program it OK,...
I have a problem with my Micro-Trak 300. Whenever I go on longer trips and higher speeds it get stuck eventually and I have to take my laptop outside and hook...
5 volts will not provide sufficient power for the output stage. Providing 5 volts directly to the PIC would keep the GPS, the TinyTrack portion of the circuit,...
Does anyone know where I can get a box to mount this thing to protect it somehow? It looks like the four holes in the corners could be used to mount it ...
There are several well known and well used phrases regarding money. Most of these have been around since the first bank notes were printed and we stopped using...
on Allen's suggestion I went ahead and hooked up the GPS. I can receive it much better now on my kenwood d700 than on my d7, but still most packets are marked...
Group: I'm puzzled by recent results with the MicroTrak 300 in my plane. I've done previous tests with a 9v transistor battery for power, and gotten good...
Bill, The Micro-Trak 300 should run fine on 14 volts. The problem is almost certainly electrical noise from the A/C bleeding into the signal. ( the battery ...
