Fun on 10GHz – First 12 Months of EME Operation

Posted on December 3, 2024 by g4hsk

Inspired by various articles written by VK7MO, G3WDG, GW4DGU and others I wanted to see what I could achieve using just a 1.2m off-set dish and 10 – 12W RF at the feed point. I had my first 1st 10GHz … Continue reading →

Fun on 10GHz – Decoding DL0SHF beacon using QO-100 system

Posted on November 23, 2024 by g4hsk

Having been away from home for a while I was keen to “get back on the radio”. EME conditions were looking good, degradation very low, Moon near Perigee and Moon pass times good, i.e. not in the middle of the … Continue reading →

10GHz Small Dish EME Project – First Initials

Posted on January 18, 2024 by g4hsk

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 – 1

Posted on April 15, 2023 by g4hsk

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’

Posted on March 21, 2023 by g4hsk

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’

Posted on March 4, 2023 by g4hsk

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 →
