[aprssig] Clueless WA4SZE Beacon Trashing 30M HF APRS

About 3 or 4 days ago, WA4SZE started operating a non-stop 24-hour beacon on 
10.149.100 MHz.   This seems to be a stepped-power beacon similar to the 
NCDF/IARU propagation beacons on the higher frequencies  This signal, 
originating from Manchester TN, is now disrupting the 10.149.200/.400 FSK APRS 
channel over a large part of North America.

Here on the west coast, this signal is peaking at S7-S8 for many hours each 
day, triggering the AGC on my 30M APRS igate receiver, rendering most APRS 
signal un-receivable.    Being only 100 Hz below the lower of the two tones for 
APRS FSK, there is no practical way to notch this signal out  of the receiver 
IF passband without damaging the FSK signal.
