VK Logger Ham Radio Forum Archive

Searching You Tube for 23cm EME, I discovered a clip that had a VK operator being decoded at the "far" end.

Listen at 1:40 into the clip

Rob You are right. A work mate has his meter read and a subsequent HUGE bill arrived. He did some investigating and found that the meter reader read the serial number - DOH. It took ages for the 3000+ bill to be rectified to the normal 350 amount (single guy), even after the Ombudsman got involved. ...

For those who know the code, try http://www.dxatlas.com/MorseRunner/ You can simulate a real radio environment by controlling the QRM, QRN, LIDS, QSB, Flutter etc etc Can change your speed, the number of callers, etc. Just Downloaded it and had a few 10 min plays and improving all the time. Lots of ...

Further info:

One station recently went to these lengths

Using 5 RX's, they are able to see V, H, +45, -45 degrees and CR (Circular Right)

Bound to hear/see everyone, HI

Peter For 2m EME is does not matter. You can use linear polarisation (either Vertical or Horizontally mounted yagi's ) and still make QSO's. The advantage occurs when you have both V and H (cross polarised) yagi's. See the following website for further explaination. http://www.ifwtech.co.uk/g3sek/em...

Ultimate 2m DX

What you can do with a single 10 element 2m yagi, 80 watts (DSE amp), no preamp, no GPS locked rig, 12mts of RG213 and using WSJT software.

VK3OF Ferrites sound nice. The split ferrites are OK, just that they do not like having water between the halves. So 100% water proof split types. That is the reason why I went for the slip on ones. How many? Some say 100w per ferrite. KB8RQ http://www.spasalon.com/kb8rq/ uses two of them per yagi o...

Agree 100% with Bob. I'm of the principle of Keeping it simple. Less connectors less water ingress points etc. Like Bob I have built YU7EF yagi's. But due to length and Ally sizes, I built two 10 elements and used normal dipoles (spilt dipoles). With 10mm fibreglass centres, and ferrites for the Bal...

Rob I'm using a DSE Amplifier Kit. As JT modes are harsh (continuous TX of tones etc) on the amp I run it about 80-100w out. I do have a fan ontop of the Heatsink blowing air down onto the amp. This comes on only when in TX. This is fed into some second hand RG213, about 14mts of it. Who knows if it...

Dave Yes this column is an inspiration. To all those who have thought about it but struggle to start. Yes it is that easy. Having got my feet wet on 2m with a 10ele YU7EF yagi (5mt boom length) and a DSE amp kit, worked 14 stations so far (JT65b). Google and Youtube my call for my home page and vide...

Justin Quoted Do they even still have a BOCP at TAFE? NO The certificates are recognised but they do not carry the weight they did years ago. On the job training, specific to the job is what is performed these days. I'm employed at the ABC, and our 2 years of training (full time) did not give us a B...

It's on the 50MHz page

DK7ZB yagi. Insulate or not, that is the question

section. First mentioned by VK4TI.

Found using the search feature on the top right hand part of the screen, typed in sleeve.

Interesting concept.

Good luck with any experimenting.

All The ex South Australian ABC News Link Van is up for sale. This is a L300 4wd with low k's. Has pump up mast (7mst from memory) manual azimuth rotation with locking facilities, air operated.

Paul and others

Great article, and the picture is worth a 1000 words. The article makes sense and is logical, will be going down this line. Ta

Thanks guys for all the help and guidance

Wayne

PS Paul, love the call sign

All Thanks for the info guys. Great bunch and full of useful ideas. You have been there done that. Ta OK will investigate the ideas given here. A staff college also suggested placing the coax in irrigation tubing to add a so called strain relief in the loop, so that the coax cable does not get too m...

Brian

Thanks for the reply.

I forgot to mention that the set up (hopefully) would be for 144-1296MHz. At 1296MHz the losses will add up alot quickly than say at 2m.

All So you have installed your tower, found and installed the fatest Heliax, now what do you use to get around the rotator? Is it just a small flexible piece which then goes onto other low loss cable to the antenna up the rotating pole? How many connectors do you use. If the latter mentioned is used...

Have a look at this website. Yes I know it is for VHF and above, but the principle is still the same.

PICAXE GOING All Just like to say that the documentation that Ron has supplied re Picaxe programming, is very precise and straight forward. I have never played with these devices before and the hold your hand documentation is a great reassurance. It was very pain free to do. Worked first time. Even...
