10GHz Transverter Project – Part 3: LNB RX Frontend
The receive side of my modular /P 10GHz transverter will use a modified LNB as the frontend followed by a down-converter to take the 618MHz output from the LNB down to 432MHz for input to the FT818 (or similar) prime-mover. … Continue reading

10GHz Transverter Project – Part 2: TX Up-Converter
Having had success with the Rev2 LO boards the same design changes were applied to the TX Up-Converter board and another order placed on JLCPCB. I prepared the two ½” Pipe Cap filters, drilled the holes in the two side … Continue reading

10GHz Transverter Project – Part 1: 10224MHz LO
Having spent many hours optimising my 10GHz EME setup I decided against trying to use the same gear for /P operation. I had great fun and learnt a lot building my QO-100 up and down converters so I decided I … Continue reading

10GHz Small Dish EME Project – First Initials
This post is just way overdue… Having spent many hours optimising the dish feed the next step was to see if I could actually keep the dish on the Moon well enough to get my first contact in the log. … Continue reading

10GHz Small Dish EME Project – Making a W2IMU Feed Horn
Having had good results on receive with my initial setup and established a baseline the next stage was to try and optimise things even more. I was very fortunate to recently obtain a wave guide (WG) switch so I finally … Continue reading

10GHz Small Dish EME Project – 1
My experiments with the small 65cms OS dish encouraged me to push on with the work needed to get the 1.2m dish up on the mast. The EchoStar dish had sat in my shed gathering dust for several months. I … Continue reading
Fun on 10GHz – 5 ‘Completed AD8307 Based Noise Meter – 28MHz / 144MHz IF’
I have been testing the noise meter modules with them connected to the 144MHz IF output of my 10GHz transverter. To make best use of the noise meter when working in the shack it ideally should work at 28MHz, i.e. … Continue reading
Fun on 10GHz – 4 ‘AD8307 Based Noise Meter – 144MHz IF’
My small (~ 65cms) dish 10GHz EME experiments have been great fun. More information can be found here. The next step is to install a larger 1.2m off-set dish. This will initially use my existing AZ / EL system, the … Continue reading
Fun on 10GHz – 3 ‘EME Experiment’
The prolonged hot and dry spell that the UK and most of Europe has experienced has meant that there’s been no rain to enhance the capabilities of my small 10GHz home setup. My small dish only has a clear take-off … Continue reading

QO-100 Experiments – Maclean MCTV-670 LNB
I was asked recently which LNB is most popular with QO-100 users and is the easiest to modify to improve frequency stability. Several “off the shelf” names sprang to mind, they’re often advertised as TCXO controlled or PLL suitable for … Continue reading
