Homemade Satellite Antenna

I was at one time quite active on the early OSCAR satellites. In those days (I’m going back over 35+ years) it was 2m to 10m linear transponder(s). Having not done anything with satellite communications for such a long time … Continue reading

An SDR based QRSS Grabber

About a year ago I purchased the NooElec Ham It Up v1.3 bare bones HF Up-converter (HFU) to use with their NeSDR SMArt dongle. The plan at that time was to get an SDR-based QRSS Grabber running online 24/7. For … Continue reading

Not QRT

It’s been several months since my last blog post. Although little has happened as far as updates to my website / Blog there’s been a fair amount of activity going on behind the scenes. Some of this activity has been … Continue reading

A new LDF4-50 Magnetic Loop Antenna

Having recently changed my car I realised this week that the diameter of my LDF5-50 Magnetic Loop (ML) is fractionally too big to fit in the back of my new car!!! So something needed to be done if I wanted … Continue reading

23cms VLNA Finally Installed at the Masthead

It’s been a long slow process but today I finally finished installing the G4DDK 23cms VLNA at the masthead. The extended timeline was partly due to some other improvements that needed to be done to the 2m EME setup and … Continue reading

23cms EME

The challenge to try EME on another band was made much easier when I heard about the SG-Lab TR1300 transverter. I could see that this could be fairly easily integrated into my existing 2m setup. Things have and continue to … Continue reading

Tidy-up of the 1.3GHz Transverter

Having completed the 1.3GHz PA and established that things work well with the transverter (TVTR) and PA located in the shack it was time to tidy things up a bit. I had a spare enclosure that matched the Anglian TVTR and … Continue reading

A Fun Couple Of Days On 23cms

Having recently completed the ~20W PA for 23cms I was looking for some activity on the band to see what difference the extra few watts would make. Unfortunately I had just missed the monthly UKAC session. Reading the UKMicrowave Digest I … Continue reading

1.3GHz 20W PA

My plan to be QRV on 23cms EME continues to move forward albeit at a rather different pace to what I’d originally envisaged. After a period of many weeks where little progress was made I’ve focussed my mind on getting … Continue reading

An Arduino Based Vector Network Analyser

My first opportunity to experience first-hand the advantages of owning a network analyser  was when Charlie, M0PZT kindly brought his MFJ-259 Analyser over and we took a look at a Magnetic Loop antenna that I’d constructed. It was suddenly so very easy … Continue reading
