Discussion Overview

The discussion revolves around maximizing radio power for moonbounce communication, focusing on the necessary power levels, equipment specifications, and existing research on lunar RF signal reflection. The scope includes practical considerations for amateur radio operators and theoretical insights from past studies.

Discussion Character

  • Exploratory, Technical explanation, Debate/contested

Main Points Raised

  • One participant inquires about the optimal wattage for bouncing signals off the Moon, indicating a need for specific power levels.
  • Another participant asks about the band being used and the power available with current setups, suggesting that these factors may influence the effectiveness of moonbounce communication.
  • A third participant reiterates the wattage question while also asking for details on operating wavelength and the specifications of transmit and receive antennas, implying that these technical details are crucial for successful communication.
  • A later reply mentions that several exploration vehicles have left RF corner reflectors on the Moon, which could aid in signal reflection, and references past research on the topic, indicating a historical context for the discussion.
  • This participant also notes the existence of published papers on reflecting RF signals from the Moon, suggesting that there is a body of work that could provide guidance on the subject.

Areas of Agreement / Disagreement

Participants have not reached a consensus on the specific power levels required for moonbounce communication, and multiple views on the necessary equipment and techniques remain present in the discussion.

Contextual Notes

Limitations include the lack of specific power level recommendations, dependence on individual setups and equipment, and unresolved details regarding the optimal operating conditions for moonbounce communication.

Hi! I am an amateur radio operator. How many watts should my radio's power be to bounce signals off the Moon?

Hi fellow HAM! What have you found so far in your searching? I think I looked it up once out of curiosity, but I don't remember what I found. What band are you planning on using to try this? How much power do you have available with your current setups? 73.

What is your operating wavelength ?
What type and how big are the transmit and receive antennas ?
 
Considering lunar radio frequency (RF) targets, several exploration vehicles left RF corner reflectors on the lunar surface to aid future radio explorers such as yourself, as well as laser and optical reflectors.

Many papers have been published on reflecting RF signals from the moon, a common exercise for radar students. I have read several papers since 1970 on this topic. This IEEE compendium offers guidance on system wavelengths, timing and power levels for transmission, reflection and reception. My IEEE membership has lapsed with retirement but many PF members likely have access as well as universities.
