Dear Don, and Topband community, Very interesting topic.
I suffer also from some noise the last period, and I decided to try to find where it comes from.I found on e-bay an vintage RDF Radio direction finder and I am preparing for my efforts.My problem is that the sense antennas have been replaced (it has 2). I have no schematic digramm or any information about this receiver. The question is: Is the LENGTH of the sense telescopic whip antenna CRITICAL ? I am almost sure the owner before used what he found available. And just in case someone of you own such a radio this is it.

My google searches have not yielded much information on something I can use on these bands or what I found was not clear to me on how to make one. My plan would be to make something and then use my mobile setup to drive and try to find the source. Please any recommendations will be highly welcome. What I do believe is that its something that gets turned on in the night hours as its not there during the day and there are times at night when it goes away. Thank in advance for your help.
