Hi all, a belated Chrismas present to the Group. As a result of a discussion
with Hugh M0WYE,  I calculated, and simulated a Bridged-T Notch Filter for
136kHz, which should reduce the level of DCF39 by about 30dB which only
giving about 2 or 3 dB loss at the top of the band. Hugh has made up the
filter and from workbench tests it seems promising. It occurs to me that
this may be of interest to those living closer to Burg that we do.

Details on

We would be interested if anyone finds it useful.

Cheers de Alan G3NYK
