Looks like they never managed to erect an antenna. Did anyone hear them at all? On Friday the 20m op told me they would be on the following night, but it didn't seem to happen. 73, Greg, ZL3IX ______

TB is always such a thrill! Arrived back from a business trip, and checked the band at SS. G3OLB and G4AMT in the log, for the first G's of the new season. Even though I have worked both stations sev

Hi Eddy, There are one or two members of this group who will contest the idea of one way prop, but I am convinced that it does happen. Even with Rx noise levels and Tx power levels taken into accoun

Having just completed some routine maintenance on my remote Rx array, I find that the buried coax runs have started to degrade quite badly. What appears to happen is that moisture enters via a tiny n

Many thanks to all those who replied to the above. The views are generally that I should either use flooded cable, or protect it with plastic conduit. I am not keen on the plastic conduit idea, as it

Hi Rick, In contrast things were not looking up at this QTH. In the first part of the test we have 2 hours of operation, between 15z and our SR, just before 17z. In that time I only managed 7 Q's by

Will operate at the low end of the band on CW (not in the test). Condx to Eu at the moment are too good to pass up, so I will try to be on CW around my SR Tx 1808, Rx 1813. Hopefully the SSB QRM will

Hi Brad, I did ask him to be on a bit earlier the other day, and he said that he can't often do that because the QRN is still too high at that time. 73, Greg, ZL3IX __________________________________

Today DF2PY took the honours of being the loudest I have ever heard a station from Eu at 5 dB over S9. This was on a rising A index after a big puff of solar wind. The QSO was about 15 min before my

Hi Dan, The problem with cheap connectors is not loss, but the type of plating they use. With the wrong type, and a trace of damp, the micron thick layers of corrosion can make very good IMD generato

Hi Joe, As one of the "DX" stations that you may be thinking of working, I would strongly recommend some "steam". Although barefoot QSO's happen, and fairly often too, they are still the exception ra

Indeed a sad loss, Bill. As a brand new amateur in 1971, I remember working Paul from my home in G-land on 80m for my first DX on that band. My condolences to his family. Greg, ZL3IX, G3ZZI , ex ZS5K

I was waiting for 3B8CF on 1822 at my SR today, when, to my surprise, I heard Tom G3OLB give a test transmission. I gave him a call, but unfortunately, he had QRN at over S9. Tom was 569 with me. Pit

Bob - just hold thumbs that this god allows coupling to the ionosphere from horizontally polarised antennas in OH. There are many locations where he doesn't allow it on TB! (At least not very often)
