Thanks for the posting! So glad to see competition in the M/M category again. And also to see what's it like to operate from there.

Thank you for this excellent brief Dave. I would like to express my strong support for the 5 year callsign renewal.

I do not support the renewal of callsigns every 5 years. There are a great number of amateurs who do not use the internet and are computer illiterate. This will lead to some amateurs letting their callsigns expire.

Hi from Portugal, Very interesting! Peter CT7ADL

I am interested in a 80 & 160 m antenna and they are on my to do list one way or another. I am strictly 20 watts or less so I aim for an efficient antenna. I had been a user of Mag Loops on receive & gave a transmitt version a go recently. For efficiency I used 4 inch diameter aluminum dryer vent tubing & 3/4 inch copper water pipe for the sense or inner loop. The vent tubing is surprisingly pricey at $8 a two foot piece thus due to price and space issues I made the main loop 4 feet square. Having never built one for transmitting I was not sure if I could by using the simple sense loop achieve a good impedance match. Indeed by trial and error I did. Apparently the larger the ( inner loop's circumfrerence divided by main loop circumference ) the lower the impedance thus a square of 3/4 copper pipe with a 7 foot circumference started giving me impedances that allowed for 1.3 or less SWR readings. I should probably learn to use my nano vna and see what the Smith Chart produced indicates & I will. Right now I have a rather large old double gang high voltage tuning capacitor with a smaller one in parallel giving me fine tuning. This is doing a bang up job on 40 meters for receive and while I can get great impedance matches I have not yet tried transmit & at 40 meters its only supposed to be 27% efficient. I really built it for 20 meters where it should be 79% efficient according to the online calculator. My capacitor is too large at the moment for 20 meters, thus shortly I will look for and buy a high voltage 30 or 40 pf max variable capacitor. Thanks for the info, kc2wvb

Nice video Rick I built the FCP for my very low top band inverted L about 2016 and its still attached to my fence, my bottom fence is only about 11 metres wide so mine folds up both sides coming back towards the house. I did some tests with a now SK amateur comparing the FCP counterpoise with traditional earth rods and grounds radials. The comment I got back was also “your much louder now”. I also constructed a half sized FCP with a transformer for 80 metres with half the turns and this also worked. My inverted L is a temporary winter aerial so very easy to get matched.

I am glad I found your video. I live in a small yard in North Carolina. I did my first experiments yesterday with an inverted L antenna and a 131 foot counterpoise. I made my first 160 meter contacts yesterday. I have some work to do, but it is a start. I learned some new things to try from your presentation.
