Thanks for all the replies. Until I get the degree in electronic engineering , I think I'll just try the shielding and leave the ferrite rod :-) Regards, Mark...

Hi all! Do you know anybody who is interested in receiving of Non Directional Beacons (long wave) or digi modes or stations on VLF band (10-150kHz) with VLF...
Dobrư den, ... Hi Mike, can you tell me if this filter is better for AM or SSB than filters in DX394? Where I can buy it in Europe and how much EUR or USD it...
this filter is much better than the AM filter in the 394, I would not use it for the SSB filter. I can sell it to europe if you can send payment to me in the...
Regrettably, all signs are that the author of the 1972 Ham Radio article on the reciprocating detector, Stirling M. Olberg, W1SNN, has become a "Silent Key" or...
