wires; electrically tuning one of the wires either higher or lower to create a 2 element antenna that might possibly have a lower angle of radiation and maybe some gain? I can get to a height of arou
VK6VZ replied: Hi Bob The loops are spaced about 28 metres at the base and the tops are very close together (about half a metre). My switching/tuning unit is based on one by G3LNP/A45ZZ (from RadCom
VK6VZ replied: Hi Bob You might like to try simply adding 66' of wire at each end of the dipole, and just slope them down to a couple of short poles (say 8' high, to keep the high voltage ends out of
VK6VZ replied: G'day I guess the answer to that question is that it all depends on whether you have any fellow topbanders nearby and what sort of signal levels you get from the rest of the world. The
G'day Down here in Western Australia, RG-11A 75 ohm cable seems virtually unobtainable these days - and VERY expensive on the rare occasions when you can get it. However, RG-6 75 ohm triple- or quad-
G'day Those topbanders who have an Autek QF-1A audio filter and who have difficult reading the very small type of its operator's manual can e-mail me and I will send them a retyped electronic version
G'day all For the last eight months or so, I have been playing around with an Drake R4C, which has been solid-stated up to the first mixer - the only two tubes left now are the 6BA6 RF amplifier and
G'day all For those familiar with those of us who live in Australia, we are very fond of anything that can be called "the largest (whatever) in the Southern Hemisphere". Being so far away from anywhe
G'day all I came on the band at 2225Z and started to call 'CQ DX' on 1833, beaming south and looking for PY2FUS. At about 2238Z, I heard a weak S1 signal and switching the delta loop array to the nor
Hi Bob I put up a brief description of the Uzi yesterday onto the reflector, which should be help. When I am better, I will try to take some photos and perhaps ask Nick VK1AA if I can put them on his
G'day Reading through the recent postings about receive performance, a couple of things struck me. 1. On the basis of 30 years-plus as a radio amateur (and a couple of years as editor of an amateur r
G'day all After inactivity since February, owing to work and family commitments, I was spurred into some activity this morning by Bob W7LR's e-mail. It is actually winter down in the southern hemisph
G'day all It was the final night of the AH3D Dxpedition and an hour before sunrise VK6VZ had anxiously checked the antennas. The previous four days of the DXpedition had yielded S1 (occasionally peak
Hi Bill - made a mistake in the first version - please could you post the version below instead? Vy 73, Steve, VK6VZ G'day all Here in Western Australia, with only Mike VK6HD and I regularly active o
A huge thanks to SP5ENA, K8GG, K8ND, W8CAR, G4VGO, AA1K, K6SE, N7RT N1EU, DF2PY and ZL3IX for their excellent contributions to my query about what kind of filters to buy to improve the signal/noise p
G'day all I noticed there has recently been some stuff on the reflector with regard to the modifying the Drake R4C. My friend Dr Frankenstein (Phil VK6APH) and myself (Igor) have recently completed p
G'day all Does anyone on the reflector know where it is possible to obtain a Murata CFJ455K8 1KHz ceramic filter at a reasonable price? My friend VK6APH and I are looking for one for a project and Mu
I think there is a bit more to Tom W8JI's posting than simply a compassionate gentleman-like one. The reality is that the disappearance of the DX window means that endangered species DX like myself h
G'day all One of the best things about a contest is that it gives you 24 or 48 hours of time in which to observe radio conditions and observe the strange quirks of propagation. This year's CQ 160 was
