I'd like to see the xtal set schematic too (very nice layout!)

He is approximately 15 miles away from me. My other 2 videos show reception from much farther away.

@@WasyaSokoly Looks like I had the BFO signal from the analyzer set at -34dBm. I probably could have been set lower than that.

@@k9yk thx i will use my xiegu X6100 HF radio with 60db attenuator to transmit BFO

There’s no ‘toggle’ to select upper or lower sideband. If you tune the BFO below the SSB signal, then you are receiving upper sideband. Tune the BFO above the SSB signal and you are receiving lower sideband.

The BFO signal is feed into the coil on the far left. The middle coil is connected to the antenna. The big coil all the way on the right is the tuning/tank coil connected to the variable condenser. The diode is tapped into the tank coil at 20 turns. The tuning condenser goes through the switch labeled "Band Shift" and the two position of that switch go to the taps at 60 and 80 turns. The tank coil has a total of 100 turns (the 100th turn tap isn't used). Flipping the switch on the right up (labeled 160m/broadcast) puts a small trimmer cap in series with the main tuning condenser to lower the capacitance and tune the 160m band.

@@k9yk Thanks. The design looks to be a good one. I just had a somewhat clever idea for a project I will never do. I presume you know what a "stolen power radio" is but I will explain for others who may read these comments. Basically you need two crystal radios and a strong station you don't want to listen to. You tune one crystal radio to the strong station and put a large capacitor on its output. The voltage from the capacitor can be used as the power supply to run an amplifier connected to the other crystal radio. This lets you get a louder signal from a weak station you do want to hear. Now for the project idea. I wonder if I could make a BFO that takes so little power that it could be run from stolen power.
