I am working on an RX antenna that requires about balanced 800 match to 75 ohm RG-6. I have some type 43 and 73 ferrite binocular cores but since this is just an experimental RX antenna I wanted to u

A nice Jennings 24V vacuum relay arrived in the mail today but I am not sure the best way to detune my cage fed tower on 160. Would shorting the cage to ground be the way? Herb, KV4FZ _______________

N1MM tells me it is 180 degrees but that is generally Antartica and Bouvet lies considerably East of that. Is there any way I can get a polyconic projection online? I want to lay out a 900-foot sing

My tower is a Rohn 45 90 footer and there must be some way of detuning it via the skirt adjustment means to make it non-resonant at 1825 kHz This is similar to electrical towers being detuned near a

Interference from them makes 1840 useless for me. Since they don't respond to my emails maybe WSJT-X could assign 1844 or 1848 to 160 in their next release. Herb Schoenbohm, KV4FZ _________________ S

The 1840 interference from the HK BC station propagates 1000's of miles. I bet they are using a solid state PA without a bandpass filter. Herb, KV4FZ _________________ Searchable Archives: http://www

1844 would be a great solution for FT-8. Now we have to convince the WSJTX people to put 1844 in their dropdown menu we they do the next release. They have 1838 for JT-65 which few ever use today and

The real question is not why W1BB is #1 or W8LRL is #2 but why there are two #3's and no #4. This goes right to the heart of how the ARRL has been wrongfully playing favorites. Herb, KV4FZ __________

Yes indeed about Stew Perry. The ARRL really fooled around with the 160-meter DXCC award. But even worse, when they issued me mine I realized I had the first ever 6-band DXCC. I asked the powers that

This is frustrating indeed as there are no DXCC card checkers in the USVI with 160-meter DXCC which the ARRL requires. They refuse to explain why. OK, so I will send the cards to them. But wait, this

Best to use a 3 or 4 wire cage feed and you will find the match easier. You should tap the tower at 50 feet and work down till you find the sweet spot. A 500 to 750 vac variable will take care of any
