Re: [tracker2] All-in-one T2
- Catching up on email again...
The commercial boards will do 136 to 162 MHz in 2.5 kHz steps.
Transmitter attack time is under 15 ms. Current drain at 6 watts is a
little over 2 amps. Receive current is about 80 mA.
They're really not meant for high duty cycles - the PA starts heating up
really fast. For testing, I've bolted a couple of the largest TO-220
heatsinks I had on hand to the thing and it does much better - I don't
have to worry about a software glitch locking it in transmit mode for 20
seconds and cooking the board.
