EME Lunar Surface Reflection Communication

BI6OPR_loogarch

Lunar surface reflection communication is one of the most advanced forms of satellite communication.
The most basic EME Connect configuration is as follows:

Other frequency bands include 50, 144, and 432, which require slightly more power. A multi-unit eight-wood system is also possible.
Of course, if you're just listening, then a 12-element U antenna or a homemade DP antenna will work.

The receiver can be a simple SDR with an amplifier, or a full-featured radio.

Is a 50-20W UV band transceiver sufficient for the FT857D?

BI6OPR_loogarch

BH3XZT It should be possible. The antenna requirements are relatively high, and I recommend a main mast of at least 4 meters with eight elements. Refer to BG7XWF's EME communication experience.

Currently, I am also trying it out. Receiving works well; I can receive large amounts of data when there is no interference. However, the antenna part still needs to be improved. I need to further refine it.

"So, a 12-unit U, or even a homemade DP antenna, would work too..." This is really unacceptable. It's off by 11 wood.

BI6OPR_loogarch

BI1NIZ Yes, currently, some foreign experts have successfully connected using 60W and DP, and also achieved successful connection with a 12-unit U.
Subsequently, I successfully received a signal using a 12-element U antenna, and the "IWK" expert also successfully received a signal using his homemade DP antenna.

I saw it, DL7APV on the other side is too scary… Actually, I think there's not much difference between the 8th and 1st units, because even with a path loss of 250dB, everything else seems insignificant.

BI6OPR_loogarch The book with the same title, "Lunar Surface Reflection Communication," was a bit too thin.
