Gary as long as the verticals are isolated above ground when not switched in. You should be ok. 73 Clive GM3POI My HF antennas are all wire verticals; 20M vertical, 30M vertical, 40M vertical, 80 INV
Don I should have mentioned that 1.9 or 1.89mhz is a very good figure to aim for before adding the hairpin. 73 Clive GM3POI Hi Clive, Nothing wrong with the hairpin as you mentioned which I really co
Yes Don, I find folding back the top loading easy. Then using a roller inductance to find the value needed to match it followed by the last stage of measuring the inductance and recreating it using A
Paul this was covered a few days ago. Aim to resonate the L at approx. 1.9mhz then put a hairpin coil across the feed point, somewhere in the region of 2.5 microhenries. Then if needed adjust the hor
Paul we know your problem is that the ground losses with your system are probably at least twice what they would be with less radial issues. Removing the L and making it a T would gain you the most.
Having been in Florida in October I can assure you there is plenty of Lightning around. I don't imagine that will die down for some weeks yet. Fully audible here as well as in the US. Check http://en
Peter when testing listening to various stations you should be mindful as to the likely incoming wave angle. I.e do not expect a very good F/B ration if the station is not low angle. Try it and see b
Doesn't say much for the DXCC checking process either. 73 Clive GM3POI hmmmmm Why would anyone with a LEGITIMATE 339 DXCC entities made on 160m made as licensed station OK1RD submit a DXCC total as C
My take on this is that having had a low inverted vee at about 80ft and a top loaded vertical over a very good ground system to compare against each other. I have found the following that despite the
There have been no uploads for OK1YQ therefore it all has to be cards. 73 Clive GM3POI Hi Joel I have the same impression as Bill mentioned. 160m paper QSL requires a card checker, however LOTW confi
JC I think you have to be careful about saying this daytime or that qso could not have happened. "It entirely depends where the station is located." An example, I have a QSL with three QSOS between m
I have been using those plugs for at least 10 years. They come in useful if you have to put on a plug in cold weather and or high winds because no braid soldering is needed. However at the back of eq
Finally, after years of frustration with several types of PL259 connectors, I've settled on the new crimp/solder type from DX Engineering. They're strong, reliable, and easy to install in minutes wh
Reflector problems this is what I wanted to say. 73 Clive GM3POI Well here the RF connection Brass / silver plated have been bought by the dozen over the years. The Compression type whilst coming in
For anyone that doubts the loss of a good 259. Google K2RIW on the subject who knows a thing or two about UHF and did some numbers on the subject. I have used for a good long time the Silver plated T
Seeing I mentioned K2RIW this is a link to his comments about 259s at 70cms much less 160m. https://www.eham.net/ehamforum/smf/index.php?topic=34680.0;wap2 73 Clive GM3POI --Original Message-- From:
I very much doubt EK8ZT. Smells very fishy, all the big EK signals are pretty well known in EU and that's not one of them. I think they saw you coming. HNY Clive GM3POI At sunset tonight I was decodi
George your last point is a good one. Take any vertical array such an 8 or 9 circle array and point it at a resonant electrical 1/4 wave vertical. The pattern will be destroyed at 200 or 500ft. The T
Ash model in also your TX antenna and see whether you need to isolate that vertical on RX with a relay. 73 Clive GM3POI Hi guys, I built a 4 Square Receiving Array for 160m at 3V8SF. I put details in
Dave, I would use a different approach, try 2 sloping wires opposite each other of the same length. They will cancel out the horizontal component of the loading and give you an overall better signal.
