FT8 – The latest data mode

I’ve posted a lot about the low power, low signal modes, JT65 and JT9 in the past and now there’s a new kid on the block. This one is called FT8 which stands for ‘Franke and Taylor, 8-FSK modulation’, developed by Steven Franke (K9AN) and Joe Taylor (K1JT). The biggest change from the slow, plodding […]

I’ve broken my Hexbeam – Again!

The broken end section of my Hexbeam with the aerial in the sky

With the title to this entry, I can imagine a collective sigh from my readers, followed by “Oh no, not again”. This time is different though, this time it was nothing to do with RF or with melted insulators.  A few weeks ago I decided to add some anti-bird measures to my aerial consisting of […]

Are you transmitting illegally on 70cms?

An interesting subject came up on our 70cms voice repeater earlier today following an incident on a local DMR box yesterday and it got me thinking. There are a lot of 70cms repeaters in the UK with input frequencies between 430 MHz and 431 MHz and many people don’t realise that our licence only allows […]

My amateur radio station in 1991

My radio shack in 1991

I was recently looking through some old photographs and I found some pictures of my old radio shack and aerials from when I still lived at home.  These photos would have been taken in the second half of 1991. The first photo is the inside of my ‘shack’ which was really just one side of […]

Listening to the Camb-Hams from the Isle of Islay

The Camb-Hams are on their usual annual pilgrimage to Scotland and I’ve worked them on a few bands and modes.  I’ve also made a couple of recordings of them on 40m CW, showing how well the Kenwood TS-590SG can read Morse Code and on 40m and 80m SSB.

Learning to code in Python – Hello Raspberry Pi!

Hello Raspberry Pi! by Ryan Heitz from Manning Publications

After my posts about building an APRS RX iGate, I entered into email discussion with Alan, K2RHK who pointed me towards his website specifically to see his experiments in APRS.  While looking through his site, I noticed he’d recommended a book for those looking to learn how to program a Raspberry Pi.  I mentioned that this was […]

What can be achieved in twelve hours of 20m JT65/JT9?

WSPR is great, I enjoy running WSPR and seeing how far I can transmit using very low power but there are a couple of drawbacks.  I appreciate this will sound as though I’m knocking WSPR but trust me, I’m really not. Firstly, it’s not a QSO mode.  I accept that many years ago, some QSOs were […]

More new test gear for the shack

miniVNA Tiny from mini RADIO SOLUTIONS

Back in 2012 I wrote about some new test gear that I’d bought for the shack.  Well time doesn’t stand still and it’s always nice to have new toys in the shack, especially if they’re useful. My miniVNA Pro always did me well but recently I’ve started doing things on higher frequencies, such as building aerials […]

A new record – G to ZL on 60m QRSS

G6NHU as seen on ZK2IK's 60m QRSS grabber

Toward the end of March I ran WSPR and QRSS on the 60m band for a couple of weeks.  I did some experiments on 60m nearly three years ago which gave good results and I was keen to improve that. I posted on the new Knights QRSS list to announce that I would be active on 60m […]

Returning to data modes after an enforced break

Home brew interface for data modes using two audio isolation transformers

My shack computer is an Apple iMac.  For a few years, I’ve operated a lot of data modes and been very successful in data contests.  I’ve always enjoyed data modes and in 2012 I operated GO6NHU to celebrate the London 2012 Olympics exclusively using data. Back in 2015, Apple released a new operating system called El Capitan and […]
