Reading about 3-wire cages and the like, I feel a serious case of shunt envy. Mine is a single wire about 18 inches from one corner of my Rohn 25, connected to the tower at about 50 feet. I used an o

I ran across a sketchy reference to this idea, described as a way to block common mode signals from making it into the shack by cutting off the paths from the coax shield to the RX input. Is there an

Just to add a bit to understanding of how CQ Skimmer and Skimmer Server work to measure SNR. The SNR for a given spot is measured over a 50 Hz bandwidth in the moment when Skimmer decides that the sp

I'm planning to build and deploy 4 receiving antennasfor 160M this summer - some mix of BOGs, K9AYs, etc.Question is, where would you aim them, from a QTH 60 miles NW of Washington DC. My main object

Thanks for the info, Tim. ON5KQ is one of our long-time RBN contributors, with something like the reference configuration (QS1R receiver, Skimmer Server 1.40.0.138, Aggregator 4.1). I wonder if maybe

I was recently reading a web page by LZ1AQ <http://www.lz1aq.signacor.com/>. It is full of fascinating data and design equations for the use of small magnetic loop antennas. There were two points, in

I should have been clearer - all his work is with small loops, typically 1 meter diameter. My interest was in the possibility of improving the performance of my omnidirectional active Skimmer antenna

By all means, please don't leave, Tom. Until recently, this sort of junk stayed on CQ-Contest. Perhaps we can give it the cold shoulder and it'll wither away. This is still the place I look to for se
