Just a quick note to say I’ve added the articles on both the Mark 1 and Mark II G3PDM receivers to my ‘Downloads’ page. Enjoy…and let me know if you have one or start building one 🙂

Toyocom TQF-456C Crystal Filter
You probably found this page as a result of a Google search for the Toyocom TQF-456C crystal filter. I seem to collect filters like this…in case they are useful in the future 😉 It seems that an eBay seller known as ‘hifissb’, who breaks down radios and sells their modules, has a large stock of […]
Microphone Connections
Finding the connection details for your favourite microphone or rig can sometimes be a bit of a challenge. I recently came across G4WPW’s website which seems to contain the connection details for every rig I’ve heard of…and many that I haven’t. You can find it here.
Avro Anson Seats
“Ladies and gentlemen, please ensure your seat backs and tray tables are in the upright position…” – well not quite on this old lady. When clearing my Mum’s house, there was a complete set of old, dusty, but unused seats from a vintage aircraft. I remember Dad mentioning something decades ago, about making the terrifying […]
16×2 LCD Display Bezel
I don’t know about you, but when I build a project, I like it to look right as well as work right. Most holes you drill can be done neatly…and / or covered by a washer or knob…but there’s a problem with 16×2 LCD display bezels; there are thousands of displays to choose from but […]
Amplifiers – book by Peter Rodmell G3ZRS
As a rather old fashioned radio ham in many ways, I’ve always had a hankering to build a linear amplifier for the HF bands. I’ve got lots of ‘junk boxes’ with stuff in them for different ideas such as: 813’s, QY3-125’s, 811A’s, 4CX250B’s etc… plus various transformers and other essential ‘stuff’. There are lots of […]
EasyPal DRM
EasyPal DRM…or Digital SSTV as many people seem to know it as I was first shown EasyPal by a ham radio friend and was astonished at the quality and resolution of the pictures he was receiving…nothing like the lo-res stuff from MMSSTV and the like. Once I got back to the shack, I downloaded the […]
G3PDM back on the bench
Having now sorted some other ‘life issues’ out, it’s time for my partially working G3PDM receiver to return to the bench. Now I have to remember where I got to last time…assuming I can read my own writing 😉
Bigger 2m band for full licensees
On Friday the 10th October 2014, Ofcom published a document that included the intention to release an additional 1MHz of spectrum on the 2m (144MHz) band…on a temporary basis. Available via a Notice of Variation (NoV) to full license holders only, the frequencies are from 146 to 147MHz…giving a full 3MHz on 2m 🙂 From […]
New Website
Well, I finally got my finger out and put up the basic site. Lots more to come but it won’t happen overnight. I do like the new WordPress release so far…
