If you are considering Tinyfsk for FSK transmit with 2Tone
decoder, here is a good buy on an Arduino Board:
http://www.sainsmart.com/arduino/control-boards/atmel-atmega328-au-mini-usb-cable-full-compatible-for-arduino-nano-3-0-a021.html
The cost is $6.92, free shipping, no tax, after applying coupon
code JULY4TH at checkout.
The only other hardware you need is a 2N2222 and 1K resistor to
drive the FSK TX port on your transmitter. After you get it
working, you might want to put it in a little metal box for RFI
protection.
