OK DX RTTY contest 2017

Map of stations worked by G6NHU on 15m in the OK DX RTTY contest 2017

What a difference five years and nearly half of a solar cycle makes.  Last weekend I entered the OK DX RTTY contest and upon checking my log, I realised it’s been five years since I last operated in this contest. In December 2012 we were approaching solar maximum and conditions were excellent.  Five years later, […]

Building a Hendricks 41dB Step RF Attenuator

Hendricks 41dB Step RF Attenuator kit

Two or three years ago I had a browser tab sitting open on the Hendricks 41dB Step RF Attenuator from Pacific Antenna/QRP Kits in California.  For some reason I never ordered one and when I finally remembered that I was going to get one, they were out of stock. I dropped them an email back […]

G6NHU DXCC certificate - CW

Back in 2011 while I was working my QSO365 project (the reason why this blog started), I reached 100 DXCC entities worked and although I applied for the award, I don’t think I ever actually posted the certificate on here. The general DXCC award is for the “mixed” category which means that you’ve worked and […]

Working duplicates in a contest

When I work a contest, most of the time I’m calling CQ and I always work duplicates.  If someone calls me and my log flags that they’re a duplicate, it doesn’t bother me in the slightest, I work them again. Some operators flatly refuse to work duplicates but I think that’s a mistake and I’d […]

DMR – My thoughts about Digital Mobile Radio

TYT MD-380 DMR UHF handheld

I’ve written a couple of times in the past about various digital voice modes and if I’m honest, I’ve been quite scathing of them.  I make no secret of the fact that I’m very happy to use repeaters for local natter but don’t like the idea of linking remote repeaters together via the internet to […]

My first new DXCC entity for over eighteen months

I’ve not been specifically chasing new DXCC entities for a while and because of this, I’ve only picked up four since 2015. I know there’s been some interest surrounding the 3C0L and 3C1L DXpedition to Annobon and Equatorial Guinea respectively over the last few weeks and although I missed out on working 3C0L, I was […]

CQ World Wide DX SSB Contest 2017

SkookumLogger at the end of the CQ WW SSB DX Contest 2017

Strange as it might seem, I’ve never put in a good solid single band entry into the CQ WW SSB contest.  If you look at the recent addition to this site, my contest results page then you can see that I came third (out of three) in 2013 for my 15m entry, first (out of […]

DXCC on 17m using FT8 – Fifty entities worked so far

My challenge to work DXCC on 17m using FT8 is coming along nicely – I’ve now worked fifty separate entities as follows. Although I’m not going to go out of my way to get them confirmed because Logbook of The World and the DXCC award system doesn’t differentiate between different data modes, it’s good to […]

SCC RTTY Championship 2017 – The results

Back in September I put an entry in to the SCC RTTY Championship and I’m happy to report that the results are out and can be seen in full here. I entered the single operator 15m section and I’m pleased to report that out of the fifteen entries, I was first. I logged 190 QSOs but […]

Increasing transmitter output power – What effect does it really have?

Difference in signals between 10W and 400W

Power is always an emotive subject so I thought it would be interesting to review transmitter power levels and see what difference increasing power makes to your signal. To start with we need to look at how signals strength is measured. In 1981 the IARU Technical Recommendation R.1 was that S9 on the HF bands […]
