[Lowfer] SIW, WM EAR mid day...

[Michael Sapp]

Hi All: Captures of SIW, WM and EAR on a rx converter configured around a (reversed) ZFY-1 Mixer, Isotemp 3.0 MHz OCXO, and 2N3904 preamp and NW EWE antenna, plus some

brick wall low pass and band pass  filtering....


SIW WM  (437.2 and 422.6 miles)  about 10~12 dB out of noise

I dialed up 20 Hz from 188.83 to 188.85 and lowest peak noise with no signals detected was -70.9, less the -48.4 signal from EAR is approximately 22.5 dB

out of the noise.
