Topband: 80m carrier
Alerted by previous emails, I listened tonight to 3526; about 30min after my sunset, I could hear the carrier...not very strong, just above the noise level but it was there. Antenna is inverted L with FCPdistance to DC area approx 4500nmCQing into reverse beacon showed 18 to 37 db from NY3A and WZ7I. Whatever the signal source, it has low angle radiationinteresting... 73 Tom CX7TT _ Topband Reflector

After so many ionizations the gas tube will fail and won't clamp on the next strike. For a time Polyphaser made a test set to verify the function of the gas tube. We use those at work to test those in use once a year and every year we find a few that have failed. Polyphaser quit selling the test set (FIST4) several years back so one will need to find another way to test themmaybe a meggar. Cecil K5DL 'snip' Topband Reflector Cecil, That's a good point.
