(meteorobs) Backscatter RADAR

[James Beauchamp]

Hi Paul, 

Here in Oklahoma I tried various frequencies with no luck.  We're just too far from the border stations.

You might not want to give up altogether on analog TV transmitters 
either.  I still don't know where the transmitters are, but during 
recent slightly enhanced propagation, I was getting usable returns on 
at least one sub-channel of ATV channel 2, 3, 4 and 5.  And this is 
on a 50MHz 6M halo, not any sort of directional antenna.  In the 
metro Detroit area, I could easily be hearing stations in 
Canada.  Have you tried monitoring each of the three sub-channels on 
each of the 2-6 ATV channels.... with a decent antenna..... for 
several hours to be SURE you can't hear anything?
