Martin, question please,

Can the MPSA06 Transistor be replace with any NPN transistor?

Thank you.

Here are a couple of In-process pictures of the Antenna tracking controller.

I added the I2C Compass because it was just here collecting dust. I plan to display the compass heading on the Serial Display along with the LAT/LAN readings received.

Yes you can. Any low power signal will work. I just have a few hundred of them to use. A 2N3904 works well also.

Rims,

I am also adding a LCD to the OpenDiyAT.

Are you using a 2nd atmel to "feed" the LCD??

The LCD is an all-in-one that I purchased on Ebay, there is no vendor name or brand to it however there are many others including I2C versions. This one communicate at 9600 baud and I am using SoftwareSerial to create a second serial port using pins 7 & 8 but you can use any pins your like. An Example of SoftwareSerial is included in the Arduino IDE. I have not started integrating this with your code otherwise I would just post a copy.

What is the purpuse of displaying compass heading, is it for calibrating the antenna direction?

Jalves any news on "video telemetry"? (at least regarding hardware you are going to use)

Right now, it serves no real purpose but to let me know what direction the antenna is pointed.

msev,

This will take time, I have to "study" the PAL signal, the Overlay captions and finally the encode and decode of the telemetry.

As you can see, it isn't a trivial task

Could you please share the info for the continuous servo mod.
