Garry, Jay & All:  Interesting observations Gary. I seem to hear DHO38 on 
23.4 24/7 and stronger at night, 21.4 NPM is usually stronger in the early 
to mid morning here

and HWU on 20.9 is usually 24/7 but not very strong.  Occassionally I hear 
GBZ on 19.6 but it is not that stong and competes with local 20kHz switching 
supply noise...

When HWU is on 18.3 I hear it fairly well.  No Alphas heard here yet 
although my antenna transformers get lossy below 18 kHz....

I see some cheap 3.000 xtals on e-bay that would match my 3.000MHz LO so I 
may try a 3.000MHz notch filter on the

IF output this winter. If I can get the IF receiver into a non-saturated 
condition with 40~50dB of LO attenuation on the IF, I might actually hear 
something in analog mode other than intermod products below 20kHz...

I see slant mode coming through on SIW....will post shortly.....
