The first amateur radio station on the moon
- controversial97 3y agoA radio club in the Netherlands were able to receive it with their twenty five meter diameter dish. https://www.camras.nl/en/blog/2024/uhf-signals-of-japanese-moon-rover-received-successfully-in-dwingeloo/ https://www.camras.nl/en/blog/2024/uhf-signals-of-japanese-m...
- rkagerer 3y agoThat's awesome. Also, I misread your last word as "fish" and for a moment there it was even more interesting.
- cqqxo4zV46cp 3y agoEverything is an antenna if you try hard enough.
- elteto 3y agoThat'd be a whale of an antenna.
- lxe 3y agoGotta get a bigger antenna for my baofeng to receive this.
- Brananarchy 3y agoI know this is a joke, but you can get a shocking amount out of a baofeng with a good antenna, a preamp and some good filtering. Whether that's worth it compared to just buying a more reliable radio probably depends on how much you want to DIY.
- ProllyInfamous 3y agoAfter my third Baofeng handheld [1], I finally had to get a "real" receiver. But the 3B's are still useful for additional listening stations and/or for friends. —73 [1] The volume potentiometer becomes unreliable after regular on/offs. The major concern is that after a few years, some "steps" of volume randomly mutes (with no indication, you just don't hear the incoming).
- tecleandor 3y agoAny recommendations for a substitute of the included antenna? Either a base or a portable.
- tomfanning 3y agoDIY: slim jim, J pole (https://m0ukd.com/calculators/slim-jim-and-j-pole-calculator/ https://m0ukd.com/calculators/slim-jim-and-j-pole-calculator...) or quarter wave ground plane (https://m0ukd.com/calculators/quarter-wave-ground-plane-antenna-calculator/ https://m0ukd.com/calculators/quarter-wave-ground-plane-ante...). A slim jim made from 450 ohm ladder line and rolled up for storage, hoisted into a tree by a cord, is a favourite. A NanoVNA will help a lot while building any of these. Commercial portable: Nagoya NA-771 (beware clones) Commercial fixed: Diamond X30, X50 or V2000 colinear. With any upgraded antenna on a receiver with little filtering like the Baofeng, you may deafen it into hearing no wanted signals if operating it in an RF-hot environment. Don't transmit without a licence.

- slow_typist 3y agoCongrats to the Japanese ham enthusiasts! Big achievement.
- RecycledEle 3y agoGood job!
- myself248 3y agoOne step closer to the coveted Elser-Mathes cup!
- jacquesm 3y agoThat's a small step on that particular challenge. The difficulty factor must be many orders of magnitude higher. I'd try optical before I'd go for radio waves, a nice laser might be easier to detect at those distances because the signal doesn't spread nearly as much. Of course your aim would have to be correspondingly better as well.

- pythonguython 3y agoDid anyone know of this earlier? This is my first time hearing of this and I’m bummed that I didn’t have time to get something set up to receive this. Not just any antenna can receive a 1w signal from the moon and the poor guy is about to be killed by the lunar night
- SamPatt 3y agoAlso bummed but also couldn't have received anything. I have a decent HF homebrew antenna setup, but nothing that would work on UHF. Very cool to see though.
- pythonguython 3y agoI work at a large lab and probably could have made something happen. But yes, it's great that they sent this out to the HAMs. Was happy to see that some people managed to capture the signal

- ajot 3y agoGreat news! Next we need to get a radio station on the moon doing MEM (or Earth-bouncing)
