I have been trying to build a simple 27MHz transmitter and receiver but have failed up to now.
I found this circuit from which I can use just the transmitter and receiver part, it all looks simple enough but I cannot figure out how to make the 9:2 transformer that connects the Arial ( or antenna ) . Could someone please tell me what I should use and how to make it?
There is also an inductor in line with the arial, what value should I use here.
I'm not interested in the demodulation and power amp, I simply want to transmit and receive the carrier.
Thanks
Garry
