Steve, he was QRV on 1813.5, Wednesday at 0945z, for at least 15 min. I worked him and then he carried on CQ'ing with no takers. He had a good signal here in ZL and I guess there would have been copy

. and Hi John, I would suggest that the only reason you didn't notice the coax getting warm, is that the dissipation is more distributed. I believe the loss would have been similar to the ceramics. A

Let me give the point of view of one particular DX station. I went into the shack after supper on Saturday (abt 08z), fully intending to "give it a bash". I tuned around the band to see what there w

Further to Tom's ealier posting on the above, I would recommend that everyone using "low noise" receiving antennas should read the new article on his web site. It is very enlightening. 73, Greg, ZL3I

Hi Charles, The flag is only 5 dB better in "gain ", meaning that the signal output will be 5 dB greater. The two are almost identical in directivity, which is the important parameter for noise redu

Continuing with the ideas put forward by Herb, one trick I pulled as ZS5K, was to make a remote up converter, which took the Topband signals from the end of my Beverage in a nearby school, and conver

I agree with the general flow of opinion on this subject. I would like to see some experiments on Topband using this mode, but in a different part of the band from standard CW, and not counting for n

Hi Don, I did some tests at VHF simulating these CFA antennas about 2 and a half years ago, while still in ZS5 land. I reported the results on this Reflector, and you may like to look up the original

Hi Folks, 1) I would be really keen to see a few of these beacons on Topband. I agree that they should be at the top end of the band to avoid interference to DX ops in the bottom part. Surely there c

Hi Tom et al, A trick I learned from a relay manufacturer a few years back, is to put some DC on the lines being switched. Just a couple of mA from a few volts is enough. It seems that the micro arc

There is not much doubt about vertical polarisation being better in ZL, Tom, but Rex and I are about 10 deg further south than Steve. Distance between Steve and ZL is over 6 000 km, so the two can't
