[Lowfer] Active 1750 meter beacons

What frequency is IZJ on? Perhaps moving the freq might cure the problem.
If the beacon is in the house maybe moving the beacon will cure the
 problem.My Beacon is about
160ft from the house. I can receive quite well on 137 and on 500 khz
 without desense, I can often 
copy WEB without desense. My beacon is on 187.492khz , I set my rec to
 189150 usb when coping
WEB. Evidently the lower sideband rejection is enough to eliminate  the
 beacon signal. Most wwvb rec
in clocks are trf with narrow selectivity.
All my wwv clocks are battery power, maybe a bypass on the batteries would
 reduce rf pickup.
Interesting problem Ed, wonder if anyone else has any ideas.

My IZJ beacon has been off the air for some time because it interfered  
with the WWVB clocks in the house. I wonder if anyone else has had a  
similar experience?
