If you grounded that little antenna you'd double your sensitivity--notice the signal increase when you plug in the AC power cord and the electrical ground is connected. Great vid--thanks!
Interesting receiver with battery supply... replace antenna to electrec mic an you can hear bats, rats and same near ultrasound birds... sounds is intresting...
Nice video, i got the 6041 model, pretty same as yours ... i got a 3 way selectivity Hz switch ... wide band, 3100, 50. Need to do some field test, to see what i can hear, away from power lines and daily interference. However first i have to construct a good LF antenna. Good Luck. Ray 9H1RA
+Ray Abela Well you may seem to know what's up in the "radio basement". Are there any voice comms below 520 khz. I used to have a Realistic DX-440 more than 10 years ago and loved listening to all kinds of stuff, but I do remember never hearing anything in voice lower than 520 on the AM broadcast band. Where could I get something that goes down this low? Is the internet the only place I could get one?

Thanks for that demo, it was useful.

an excellent performing small sized antenna for these is a PA0RDT mini-whip, they work between10khz to 30mhz and are easy and inexpensive to build.
Great Thanks
