First day out in 2023 at the Shack:

“……….. A few club members were at the shack on  Saturday, Paul mm7pol, Stuart mm7swm, Alan gm4toq, Ernie gm0ezp.

We had a good afternoon in fine winter sun weather. Paul had brought up his ft991a to use as he is familiar with its operation and was hoping to take advantage of the elevated site, tower and beam. Unfortunately when using the vhf beam it had a high swr making it unusable.
Operation turned to using the end fed wire…………………… Ernie GM0EZP”

Replacement rotator installed.

Last year (31/07/21), following the installation of the main aerials on the tower, it was found that although the Rotor rotated the ‘array’, it didn’t track the direction on the Controller’s indicator panel. To repair this fault meant the raising of the array to allow the Rotator to be removed. This was done earlier this year.

See HOMEPAGE  PICTURE DIARY (Oct 22) showing some of the ‘team’ working on the re-installation.


Following the major leaks in the Operating Shack, the Shack was completely stripped of contents; re-decoration and a rebuild took place of the operating bench. 


From previous Diary entry – following a major leak in Operating Shack – Ernie GM0EZP:

“……….We could not have asked for better weather today. Charles had organised all the kit required for the job which was great. Paul and Scott did a great job of cleaning around the aluminium edging and the giving it a Liberal coat of roof sealing paint.

Inside all flooring was removed and almost completely dried in the sun. A heater was left running g most of the afternoon to assist drying out the floor and walls.
Sam with a little help from Alan and me got the rotator cable removed, so it’s on its way back to Sam’s for him to work his magic on the rotator and controller
At the end of the day everything was put back into the shack for storage and will require another day of drying before being laying back down.
All in all a good amount of work was completed and hopefully that is the leak sorted. Another day to put the shack back together should do it…………………..”

19/09/20: MM0ZUN, GM4TOQ

  • Unloaded a pile of slabs next to the shack taken up by the tractor

  • Spent a few hours on making fence posts out of what we can reuse of the old fence ones.  Ground and cut then welded the remaining fence posts into a usable state, the bottom ends that had previously been in the ground had rusted away

  • Stock take of fencing bits that can be reused and worked out we need to buy approx 80m of bar for the rungs in the fence. Alan will check up on supplier

  • A lot of the fence along the top in place, still missing some of the bar for it though but have the posts and top rail in
  • Cut down some bushes in the fence line and where the base of the tower will go. Need to remove roots from there, this can be done when we have the digger up for doing the hole for the tower base. Once the branches have dried a bit they can be burnt

Ground around both shacks re-instated after tractor & dumper action. Looking good!


New tower gifted to the Club. Decision to ‘scrap’ old one but re-use certain items. New tower has to be collected. To be organised.


Posted by Kenny – MM0ZUN on our MEMBERS FORUM:

“I’ve added some photos from today of getting the shack roughly into its final location.

This wouldn’t have been possible to get done without Gary and some of his friends work.



Move Shack#1 (Newest Shack) and Tower for ease of access and refurbishment.


Cleared the rhododendrons and cut the dead tree. (see new photos added to PHOTOS/COCHNO_Shack (Club Members only))

Dropped the Tower, removed the HF beam & VHF collinear.

Well this Project is well underway thanks to the efforts of Alan – GM4TOQ, Alan’s son Garry & Mate, Sam – GM4BGS and Sam’s son Peter.

So where are we at?

Well as you know (or may not – see my thoughts in this POST#25 (Members only)) there is a pile of work to be done.
