Longwave Listening Great Last Night

[WU2D]

Gee maybe I should dig out the old LF RX. I have a homebrew Receiver that I built back in 1990. I will post pictures of it in the Photo Galleries section.

It is basically an upconverting superhet which uses a double balanced mixer backwards, that is, the input is the IF Port and the Output is the RF Port. The thing was set up for narrow CW only with four 4.0 Mhz crystals in a ladder. It used a rechargeable battery for low noise operation. The antenna was an active probe whip which is 3 feet long with a mag mount. This antenna used an FET and a couple of emitter followers.  It looked like a 5/8 wave 2M whip and as you can guess I only operated the rig mobile. This allowed me to go to quiet spots and listen. 

I used to have a beacon on 187 kHz but no more. I could copy my 1 Watt input power beacon 25 miles away at 60 MPH going down the highway..
