The last weekend in October is the CQ World Wide contest – The CQ WW is the largest Amateur Radio competition in the world. Over 35,000 participants take to the airwaves with the goal of making as many contacts with as many different DXCC entities and CQ Zones as possible. Normally I use contests as […]

Proppy Propagation Prediction
Proppy is a simple to use web-based propagation prediction tool which allows users to predict HF propagation conditions, select appropriate HF frequencies for point to point links and understand what geographic coverage they can expect to achieve with their transmitter across time for a given frequency. The below shows how to use the basic functionality […]

A mini dxpedition
Everyone loves a dxpedition, an exotic location in the sunshine working through a pileup of hunters desperate to get that rare location in their logbooks…. somewhere like…. Dorset, UK?!? Or to be more precise the Hinknowle Cider Apple Farm campsite, IO80PS. I was here camping with the family for 4 nights this August, the weather […]

EUHFC – How high is my dipole?!?
This weekend was the European HF Championship. The EUHFC is run by the Slovenia Contest Club. During the contest European amateurs try to contact as many other European amateurs as posible to compete for the title of “European HF Champion”. The contest is short in duration, just 12 hours, so I decided to use it […]

TinyGS Update
I previously posted here about building a TinyGS earth station. It’s now been running for three weeks and I am happy with the results. I am seeing packets on a regular basis as satellites pass overhead and everything seems to be working OK! The antenna I am using is not ideal – a wideband discone […]

Signals from space!
I’ve previously played about with Meshtastic. I run two Meshtastic nodes from my home as permanent infrastructure contributing to the mesh on the South Coast. Currently this consists of two Heltec V3 nodes, one configured with an omni-directional antenna and one with a directional antenna pointing a a hilltop near my home. This configuration was […]

QRP and the ‘super droopy’ T2FD
I’ve been a bit busy for radio over the last few weeks but I have found time for a few simple experiments. For the past month I have been trying to limit my HF use to QRP (low power) operation using 10w of output power on the 40 and 20m bands in the margins around […]

I do not like the zoo!
Today the family decided to go to the zoo for the day…. I’m not a big fan of the zoo so it seemed like a great opportunity to get away for a few hours of HF. I decided to walk from my holiday cottage to Northam Burrows which is the site of a Second World […]

SPDX – A Flagpole Of Opportunity
This weekend was the SPDX contest. In the SP DX Contest, competitors are divided into two groups – Polish stations and foreign stations outside of Poland. The aim is for operators outside of Poland to make as many QSOs to Polish stations and visa versa. As I’m currently on holiday I thought this would be […]
