I´ve tried to inquire how it works but it has been awfully silent from that direction.
I can tell one story, no science in this but for whatever it´s worth. During a CQWW CW 160 contest I was sitting on a frequency running stations, it was around 19Z so I worked lots of Asia JA´s and stuff. All of a sudden OH8X planted them self 200 Hz from my frequency (go figure). I didn´t move but stayed on the fq, after all I have confidence in my antenna and station. I could hear what they worked and they clearly worked much less JA´s then me, and I clearly worked more stations per hour. Even if they where 30 over S-9 on my TX antenna I could, thanks to Beverage RX antennas, copy the stations calling me. At the time my antenna was a 100ft top loaded vertical over a huge radial field ( about 250 radials). IMO we would have comparable propagation, OH8X and SM2EKM are situated at the same latitude but east/west separation is about 125 miles or so. In any case at that time their 3 el Yagi did not beat my vertical. This has been a interesting topic to follow. Now back into my hole again. 73 Jim SM2EKM ----------------------------------------- On 2012-10-25 10:30, Clive GM3POI wrote:
Yes Gary, After blowing then away in a CQ 160m Contest by 1m points I figured it was rather an expensive lesson they learn. I was using my 51ft top loaded vertical and a lot of wire under it. 73 Clive GM3POI -----Original Message-- Subject: Re: Topband: HFTA, Radio Arcala, general comments As I recall they never blew up the receiver here, unlike TF4M, GM3POI, and others in that direction from KL7 who were consistently available during times of low absorption over the N Pole. Then again, who knows what antenna array they were using or the ERP when heard. I'd still like to know their A/B results as there's something to be learned from all that hard work. 73, Gary NL7Y
