Digital audio noise on receive when using WIRES-X

Back in February, I bought myself a Yaesu FTM-100DE with the intent to use it connected to a PC for WIRES-X. In the meantime, I’ve been using it to talk to friends via a YSFReflector and I wrote about how to build a Yaesu System Fusion reflector on this site here. When I finally got […]

Installing a radio into my car

Mazda 6 with Watson W-770HB

About a year ago I changed my car and it’s taken a while to get around to fitting the radio into it. I’ve missed having a wireless in the car and recently resorted to keeping a handheld in the glove box so at least I could natter on the local repeater while driving around town. […]

Updated guide to setting up an APRS RX only iGate using a Raspberry Pi, RTL-SDR dongle and a pre-built image

Initial test of the RPi and RTL-SDR Dongle APRS RX only iGate using Raspbian Stretch

** image has been updated as of 21/04/2018 to resolve the problems some people had booting their Pi ** This post is an updated version of the original article I wrote in February 2017.  It’s using Raspbian Stretch rather than Raspbian Jessie, has Direwolf 1.4 instead of Direwolf 1.3 and the method used to start […]

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 […]

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 […]

How to replace the noisy fan in an Icom ID-5100 with a much quieter one

Inside of the Icom ID-5100 showing the new fan in place

I’m a happy owner of two Icom ID-5100 radios, one is mounted in the car and I use the other one in the shack on low power for working the local repeaters.  It doesn’t get much use but I’m monitoring GB3CL and GB7TE most of the time. About the only thing which I don’t like about this […]

MB7UIV is back

A little history In January 2000 I started running the first licensed APRS Internet gateway in the UK originally with the callsign GB7UIV.  Within a week of experiments starting on the 26th January 2000, the gateway was on air and connected to the internet 24/7 except for periods when the connection dropped out and the […]

Setting up an APRS RX only iGate using a Raspberry Pi, RTL-SDR dongle and a pre-built image

After my previous post, it was suggested that an easier way to set up a receive only APRS iGate would be to provide a pre-built image which only needs slight tweaking to go live.  That seemed like a good idea to me so I’ve prepared an image that just requires a handful of configuration changes which I will […]

A guide to setting up an APRS receive only iGate using a Raspberry Pi and an RTL-SDR dongle

** This is now outdated, I recommend the pre-built image from here rather than following these instructions.  I can not support this method any more ** I originally bought a Raspberry Pi back in October 2012 but as I didn’t have a specific purpose in mind for it, I quickly sold it again.  A few […]
