Homepage

Hi! My name is Gavin, welcome to my webpage.  I hope to use this space to chronicle my adventures in amateur radio and electronics.

  • In late August 2015 I added a page called “Shop” to use as a way to offer for sale components I no longer plan to use, finished or unfinished kits I’ve no need for anymore and surplus equipment.

I have a motto; “Anything made by man can be fixed by man, no matter how hard it seems”. While this obviously applies to repairing  something which is broken, it also applies to the attitude I have towards experimenting where it removes the fear or worry I have in damaging something during my designing, modding or constructing, mechanical or electrical.  This allows me to broaden my imagination and try difficult and risky experiments or mods. If I fail, then fixing or putting something back to how it was is always a possibility, with no harm done. However an interesting, and unexpected consequence of this is motto, is the amount of tools it leads you to acquire!  I could create a whole webpage on the just the number and types of crimping tools I have 🙂

To try and keep things simple and presentable,  I’ve split the website into sections;

  • Projects: This page covers my electronic projects, usually PICAXE based.
  • Snippets: Posts about things others might find useful, please give me feedback if this is the case.
  • Selective Tweets: Tweets I post and tag with #WP, usually because they are relevant to my Projects or Snippets
  • Shop: A page where you’ll find components, finished or unfinished kits I no longer need plus any surplus equipment
  • Logbook: My ham radio contacts.

Please use the feedback form if you would like to get in touch or comments on anything you find on this site.  If you share any content all I ask is you acknowledge me as the source and provide a link to the article on Geekshed.co.uk.


Getting started in Meteor Scatter (MS)

Getting started in Meteor Scatter (MS)

I’d like to share with you all my passion for working stations on VHF (6m, 4m and 2m) using Meteor Scatter (MS) as the propagation mode.  I wrote this during the peak of the Perseid meteor shower in 2015 as it’s much more likely that a newcomer, even with a modest VHF station, inspired by the article … … Continue reading

Ecoflex-15 Degradation

Ecoflex-15 Degradation

The Problem As part of the G3PYE contest minions I bought a 2x 25m runs of Ecoflex-15 back in 2011 and a year later we started to notice less power at the end of them, we initially put this down to a poor cable batch or damage from use/storage and after some basic analysis we … … Continue reading

From Monday 2nd – Friday 6th December 2013, G3VFC, G3ZAY, M0BLF, M0VFC and M1BXF will be operating as ZD8UW from Green Mountain, Ascension Island. We’ll be active on 40m-10m, mainly SSB and CW.

So I was the driven [element] in this bit of fun; We done this before setting up for a 70cm RSGB UKAC from our usual site at Worts Causeway. Radio was a Yaesu FT-817 using internal batteries at 2.5w.

North Ronaldsay EU-009 Holiday

North Ronaldsay EU-009 Holiday

So my girlfriend wanted the chance to see the Aurora (northern lights) and as it is her birthday on New Year’s eve we decided we should get away for New Year.  After a few searches, and shocks at the prices of going to places like Norway, Iceland or somewhere similarly that far north, we found … … Continue reading

Shack Panorama

Shack Panorama

So after sending a quick picture to Twitter showing my clean shack I got quite a few replies.  I thought therefore it would be good to show the shack in its entirety. I first Googled to see if Picasa could do it and got a result back for Microsoft’s Image Composite Editor (could this be … … Continue reading

6m DX Window

So I can’t get it out of my head all the grief I got after operating within the top 3 KHz of the DX window on the 6m band…  The conditions were such that there was a chance of some North African stations being on the band so I thought I’d position myself at the … … Continue reading

PC Trouble

So about a week ago I tweeted that my PC had crashed and on boot-up I got error messages saying there were missing DLL and SYS files for the programs which were running when the crash happened.  All week the PC had sputtered which was uncharacteristic of it being quite a decent machine.  I decided … … Continue reading

For Those Moments When One Switch Won’t Do

For Those Moments When One Switch Won’t Do

So I’ve been after a few RF switches to allow me to switch various radios to various antennas. In this instance I wanted to switch antennas to my IC-910 radio (the 2m and 70cm side only), my funcube dongle and 2m transverter (connected to my Flex-1500).  The antennas were my 2m 9 element YU7EF, the … … Continue reading
