    I don't know all the names that what you're looking for could possibly go by but perhaps your searching skills would be enhanced with ... I don't know ... I'm a stump.

I thought I was on 1590, and I was. I was also clear on 290 as well. Two double A batteries so let's hope it was just a house-wide thing with the little antenna I had.
    Maybe not...

    All the world’s a stage, but obviously the play is unrehearsed and everybody is ad-libbing his lines. Maybe that’s why it’s hard to tell if we’re living in a tragedy or a farce.

    Okay, how about this one, then? ;)

    Yeah. Those things send out engine jamming waves at low frequencies.

    This is a little home brew HF station that I scratch built years ago . It works on 160, 75/80, and 40 meters. The transmitter on the right is a 6L6 crystal Oscillator. The receiver on the left is a single tube 6SN7 regen. The unit in the middle is a two tube audio amp/power supply for the receiver. The transmitter was built on the chassis of an old Heath lunch box. The receiver and audio amp/power supply were bread boarded. I made the front panels from the doors of an automotive parts cabinet. I can use the transmitter on AM by running the modulated B+ from another lunch box right to the plate of the 6L6.

    Oh, sure, go ahead and duck your responsibility.

    Very nice. I want to construct a multiband, solid-state all-mode transceiver/receiver combo some day but the bike homebrewing tends to take all my free project time.
