Repost from MicroTrack Mailing List:


Well, I just sent out my prototype board for production to try a 30 Watt, single channel Micro-Trak transmitter. The board is 4.7 X 2.4 inches and has a BNC RF output. With a 17 volt supply, it could potentially produce 45 Watts of output power! 

Today I realized that the next larger sized amplifier module is in the same size case, and it might even be possible to drop in the 60 Watt module ( 75 Watts at 17 VDC!) I can visualize APRS purists filling their molotov cockatails even as we speak....

I have taken crazy-extravagant precautions to prevent the RF from swamping the PIC, but there is ony one way to know for sure if its going to work. I should have the boards back in a couple of days and will let you knwo how it works, and put up photos (unless if fails massively, in which case, forget I even brought it up!)
