G'day Thanks to all those who offered me suggestions/advice on buying/making a new rotary antenna switch. The most popular options suggested for purchasing a remote antenna switch (i.e. switch box, p
G'day Many thanks to all those who offered advice on my question as to whether I should pursue a rotatable Flag or a rotatable 2-element end-fire array (as per the Titanex and the ON4UN array on page
G'day, Those who are interested in contacting historic lighthouses around the world may like to look out for VK6VZ/6 in the Stew Perry Topband Distance Challenge on 29/30 December. I will be operatin
G'day, To used the Australian vernacular, it looks like I "stuffed-up" my previous posting on the VK6VZ/6 operation in the Stew Perry Topband Distance Challenge on 29/30 December, specifically the po
G'day es HNY, It has been interesting to read the posts of the good conditions (for some) between the USA and Europe - and the disappointment/puzzlement of others with good stations in USA/Europe, wh
G'day all, Since I posted the note about using a 40673 instead of a 3SK88 in the KD9SV premamplifier, I have had several e-mails inquiring about what currently commercially available MOSFETs could be
G'day My friend Phil VK6APH and I are in the process of building a rotatable 1.8MHz receive array, using an Yaesu G800 rotator we picked up cheaply. The G800 came without a control box and although i
G'day As have said previously on the reflector, Phil VK6APH and I are in the process of building a 1.8MHz rotatable rx array. The choice has come down to either a K6SE 'Flag' type antenna, or a 2-ele
G'day Goose/Tom W8JI and all, I guess when Stew Perry was writing this, there was a lot less readily available data on earth systems than there is today. As you say, we now know that a radial system
G'day My friend Phil VK6APH recently built the high pass filter that Greg ZL3IX provided the circuit for - a seven-section Chebyshev. He used cheap metalised polyester film capacitors, from a local h
G'day If anyone has contact with AP2ARS, please could they ask Peter/Robert if they can try 1828 at 2100Z. At around this time, they have RST 589 signals into Western Australia and would find they al
G'day An interesting example of localised propagation of 160m signals occurred last night in VK6. At around 1100Z, I received a call from Mike VK6HD, some 450 km south east of me, to say the 3D2 was
G'day It was interesting to read of the good conditions from VK6 into Europe in the last day - which unfortunately I missed owing to being fast asleep after a very heavy day at work. However, I am no
G'day Tom and the gang A few facts about mainland Australia. It covers an area of of some 7,614,500 square kms and is about equal in size to the USA (excluding Alaska), almost twice the combined area
G'day, A friend of mine Phil VK6APH has recently built the famous KD9SV variable gain 160m preamp, as published in Ham Radio October 1989. As it was difficult to obtain an NEC 3SK88 that Gary used in
G'day all, If there are SSB contest stations outside of the US (Europe, Asia, Oceania or wherever) who try and run US stations (or others) below 1843, then contestants should simply ignore them - or
G'day all, This year I had a clear-out of some old magazines and went carefully through them, looking for nuggets of 1.8MHz information. One of the best pieces I found came from a Bill Orr W6SAI 'Ant
Good conditions into Europe this morning, with an opening extending from Eire west to Germany and north to Scandinavia. Signals were peaking S8-9 (OZ7YY, LA5HE and [heard] G3XGC). As often happens, w
Hi Frank, I worked 150 countries on 1.8MHz using a bent dipole at 45' high - made out of a 3.5MHz flat-top dipole, with 66' of wire soldered onto each end and sloped/drooped semi-vertically down to t
G'day from Glen Forrest Thanks to all those on the reflector who wished me well after the tower/antennas got vandalised. Everthing is back up in the air now - just in time for the equinox - and there
