Curious what you used for a loop antenna?
I am trying to track down a disk to dawn device that puts out 1KHZ wide
signals on 1817, 1825 and 1828. Nowhere else. My Tecsun unfortunately
I had a post-military (comms and avionics) second career of ~30 years
in EMC engineering, and found a small untuned loop works well on some
hand held radios, not so well on others. Loops like the one below work
well enough on an AOR-8000, 8200 and VR500; not so sensitive on a
Kenwood TH-F6A.
It's untuned, but sensitive enough if you get to the general area of the
source, and will pick up local AMBC stations. I started carrying setups
like the one in the link at work; a LOT of engineers -- and their
managers -- don't understand how to use test equipment and couldn't
figure out how I could get good results with uncalibrated equipment.
