Data (RTTY/PSK) contesting – The anatomy of an ideal QSO

I like contesting.  I like data contesting and I operate a lot in data contests.  I don’t generally have the time to dedicate to making a winning entry although for the big events, I’ll try and make a good score and aim to finish high up in the table.  I’ve done well enough though and […]

Testing my dummy load

Back in August last year I built a dummy load out of a bunch of resistors, a paint tin and some oil.  I said at the time that it seems to work fine on HF but not so well on VHF.  After I used the load last weekend to test my aerial, I thought perhaps […]

Winding coils for various radio projects

Over the last few days I’ve found myself winding coils for construction projects. I dug out my MKARS80 kit from where it’s been sitting for the best part of a year and the next stage was fitting some trifilar wound transformers. These are made by lightly twisting together three lengths of 38swg enamelled wire and […]

The CQ WPX RTTY Contest 2012

Anyone who follows me on Twitter or reads this site will have noticed that I was planning on taking part in the CQ WPX RTTY contest last weekend and that I was keen to sort my aerial out in advance.  I lowered the mast, fitted my new balun along with two new coax tails and […]

You can never have too many 0.1uF decoupling capacitors

A couple of weeks ago I needed to repair my iPod transmitter for the car and the fix was a simple one – Resolder the power supply cable and replace the decoupling capacitor because it had broken. The problem was that I had no ceramic disc 0.1uF capacitors.  I ended up using a miniature multi-layer […]

Planning permission – I had a visit and a letter from the council

Planning permission is a subject I’ve steered clear of on this blog for one main reason.  I don’t have any.  I used to have a twenty foot pole on the side of my house with a seventeen foot long 2m beam for over fifteen years along with an 18ft vertical colinear for 2m/70cms, all with […]

Mast is up, beam is up – It’s all done in time for CQ WW SSB

The crowds descended on my QTH again today in order to finish what we started back on the 10th September, just six weeks ago.  Today we had Chris, M6GSD, Tony, G0MBA, Colin, M1EAK, Yan, M0YNK, Bill, G0OAX and Chris’ son, Dean here. To start with, Chris drilled the holes to mount the chemical anchors for […]

Now this is what you call a pulley!

As has been well publicised in this blog, Yan, M0YNK has been constructing most of the hardware to go with my mast.  I popped into his workshop on the way home tonight to find him working on a pulley for me.  Originally we’d bought one which wasn’t man enough for the job and Yan had […]

My Alimast is up but there’s no aerial on top (lots of images in this post)

There was no work done on my Alimast from Aerial-Parts of Colchester last weekend because I was at the RSGB Convention so the plan was to get everything finished off this weekend.  The design for the bracket had been worked out and I’d done all the indoor work on my new rotator.  The weather forecast […]

Days 266 to 275, Alimast sections are all assembled

Lots of QSOs over these ten days, with quite a few data contacts during contests.  Here’s a list. At the weekend I finished off the assembly of my Alimast sections.  I’d done a lot on Saturday as per my previous update but having ripped so much skin off my knuckles, the first thing I did […]
