Topband: BCB interference ?

[wb6rse1 at mac.com]

I had a local BC station start to produce spurs that overloaded an external preamp for my full size RX flag. The Array Solutions W3NQN RX filter did the job. I tried an Array Solutions AS-402 BCB High Pass Filter but it doesn’t have the brick wall response of the W3NQN design. For all I know, my local BC station is still malfunctioning. The Clifton Lab design looks as if it should work comparably to the W3NQN filter.

The Array Solutions AS-RXFEP front end protector should be consider if your RX and RX antennas are close and your run QRO.
