Here is the foto of my finished receiver assembled during Diwali holidays. All modules and box was made earlier. I assembled it or to be exact reassembled individual modules made earlier for different project. Put. A xtal qrp tx on 1/4 wire antenna. (for this transmitter see this post :- https://vu3inj.blogspot.com/2014/12/7159kc-beacon-cw-tx.html ) .
receiver sounds good. Tested enough. Now need to increase tx power and see whether i can be received on 7159 kc xtal around 100km ?
i am putting the front end band-pass filter to load external antennas. its a very standard design i used with my other 40 meter xtal receivers.
