simple tx & rx circuit
Hello,
I need schematic for a very simple and implementable Tx and Rx with very low data rate requirements.
ASK, FSK, or any other modulation scheme is OK.
Excluding microcontroller chips, I hope not to use any IC's or ready made T/Rx modules.
Power is required to cover distance of about 20m (none-line of sight)
For antenna size issue, i hope to get operation frequency as high and in free band as possible.
If anyone succeeded to fetch similar circuit or close to its c/cs online or he already designed before, please share.
Thank you all,
Ahmad,
