I did a similar receiver using a 602 IC for 14Mhz LO oscillator and mixer, it works great on 20 meters. It needed a 1k ohm pot in the antenna input to ground to control the input RF gain. Building the 20 meter receiver and listening to Lebanon with 10' of wire for an antenna here in Illinois USA was neat. Keep building it is cool seeing what others are doing. 73 Jimmy, ARRL TC, WX9DX
Peter that receiver is a little ripper! Well done on yet another educational video. I like the way to explain what's in the box. Keep up the great work and I look forward to another QRP contact soon! 73, Craig VK3CRG
What a great little Rx I am currently helping a couple of lads (11 and 14yr olds) to get the foundation license This would make a great project form them. Do you have a circuit diagram I could give them to try and build. I have watched most of your videos here on TH-cam. Thanks for making them. 73's Steve 2E0UEH

Another great video Peter, many thanks ....
Very cool
@superdallasdj I did not understand that either!
how much tuning do you have around your crystal L.O. grt vid
Awesome Peter

Heyy mate Nice receiver!!!!! could you please email me the schematic for this? or is there a place i can find it??? thanks a million!
Prefect for swl work. Nothing better than "roll your own" gives the feeling of owner ship. Unlike buy it from the shelf clones don't give tks de kV4li
Any schematic ?
I think regen is better... DCs work without RF amplification
yes!
I have always enjoyed.
This particular receiver is very interesting.
I am also looking forward to the next. ７３！

he didn't understand what he says, i think :))
