[Lowfer] CFH on 73.6 kHz

[wa3tts at verizon.net]

Garry, John: I'm hearing an MSK station on my analog converter at  73.6 kHz  in mid afternoon along with fairly co nstant S9+ static crashes on my e-probe. Perhaps 10 dB or more above the QRN in a 500Hz CW filter.

Several well placed AC line filters here in the house have greatly improved LF/MF/HF e-probe.  My DVR and the digital controller in the gas stove were particularly prolific noise sources.Having 5 uninterruptle power supplies in the house was an issue as well.  A little DSO-188 pocket scope and clip-on ferrite bead inductor with a short coax jumper to the scope inputtracked down all the major AC line noises quite handily....

Nice to see CFH active again on 73.6 kHz. Haven't noticed it for awhile.
