Re: 2Metre SSB up and down the coast VK2

A bit confusing having a primary and secondary calling frequencies on two metres as per the band plan. So I will assume that 144.200 is for AE and M/S from early morning till 2300z and then 144.100 after. 6 metres has a defined band plan so there should be no confusion. 50.100 is not a calling frequ...

Re: Opek HVT-400. Mobile?

I've been using an opec 400 for 3 years and the only problem is the locking screws keep coming loose. After tuning use some loctite should fix. 80m is very narrow but I use a auto tuner so is quite useable,tuner takes care of the bands too. A spring base takes care of most of the whipping about. min...

Re: What are the chances of Aurora signals from VK0JJJ?

Hi Steve,

The only other clue is the time of day.I see you worked vk0ix 14th Jan 1995 at 0800z.
I worked him a week later,31st Jan 1995 at 0930z,thats about the same time of the day.

Has Craigs beacon been heard anywhere as yet?

Hi Wayne, I recently mounted a 5 band vertical on the house roof,its tin and covers a large area. It picked up every bit of crud from inside the house even the crt tvs. I then put it on the tin roof of a large shed,now noise free and works well with good reports. I used rg213 as the shed is about 20...

Re: Looking for fibreglass pole / thick wall tube

Hi Adam

The power companies use a fibreglass pole for pulling fuses.
It is about 2 meters by 40mm with brass fittings so they can be screwed together.
I dont know where to buy but if you know someone in the industry there.
cheers and happy new year.

Re: Element mounting ideas/methods

About the only difference between stauff and pirtec clamps is the colour,pirtec is blue,stauff is green.
Use a large flat washer to get them tighter without sqashing.
Pirtec usually sell both brands

Re: Element mounting ideas/methods

Hi John,

I use Pirtec hydraulic pipe fittings,they are available with various hole sizes to suit your element diameter.
Then use steel roofing screws to direct mount to a square boom,very easy and strong.

At the time there was no aurora and no au type growl here.Certainly strange,it must have been some sort of atmospheric disturbance to the north of...
