Can you bounce radio signals off the Moon? 📡 Yes you can! What about up at a Super High Frequency such as the ham radio X band - 10 GHz. Well using WSJT and a decent amount of power, we attempted to do just that!

Earth-Moon-Earth communication (EME), also known as moonbounce, is a radio communications technique that relies on the propagation of radio waves from an Earth-based transmitter directed via reflection from the surface of the Moon back to an Earth-based receiver.
Amateur Radio operators use this form of communication on almost all bands from 50 MHz and above.

@saxpert 2 года назад

When the moon has a low elevation, isn't there an atmospheric refractive effect when working at 10gig? In this case the elevation of your dish might be different from what you see with the scope. Just an idea. The higher the elevation the less the difference between both.

@Sparky5999 3 года назад

For a ham getting into Moonbounce, what is the cost of required hardware seen on the tripod? And now hard is it to "tune up", adjust to get first light?

@HamRadioDX 3 года назад

The transverter and PA is a Kuhne DB6NT design. You can look those up on his website. The dish, tripod, level and adjustments are all from various places picked up over time.

@stargazer7644 3 года назад

The 60W amp is going to make your eyes water. About 700 euro for the transverter, 4,100 euro for the 60W amp, 240 euro for the LNA, probably close to a thousand dollars US for the power supply, dish, switch, sequencer, tripod and various other bits and bobs you need. So about USD $6k for what's on the tripod, plus USD $1500 for the radio, and another thousand for a couple of laptops. So about $9k. This price can vary tremendously depending on what you build vs what you buy, and some of it has to be found on the surplus market, so that varies a lot as well. As far as tuning, if you buy a premade dish and feed that are already engineered to work together, it is easy. If you make your own, it can be quite fiddly. Most folks on 10G EME use much larger dishes to save money with a lower powered amp. For example, if you use a 1.2 meter dish instead of a 60cm one, you only need a 15W amp for the same transmit performance. It also makes your receiver 6db more sensitive. That would save you several thousand dollars, but it is harder to point.

@donaldsmith3048 Год назад

I am new. Can EME be done at lower frequency? How low?

@HamRadioDX Год назад

It's possible, but it's difficult due to ionospheric absorption. At lower frequencies, radio waves can be absorbed by the ionosphere, which can weaken or distort the signal that is being transmitted. Especially below about 30 MHz, which are more likely to be absorbed by the ionosphere than higher frequencies. Lower frequencies can also be affected by other forms of interference, such as man-made noise and natural sources of electromagnetic radiation. These can add to the noise level of the signal and make it more difficult to distinguish the desired signal from other sources.

@donaldsmith3048 Год назад

@@HamRadioDX I was not thinking of HF. I know that most of that gets bounced back to earth. I was thinking about 70 cm or maybe 2m. There is no way I could get anything in the GHz range. But I have VHF and UHF. Someone was talking about someone had a UHF Yage pointing up. That is the only think I could think of was EME.
