G0MTN QRP 144 MHz EME Moonbounce

Congrats
My only EME qso was with W5UN
2006
I ran 100w 10 ele yagi JT65

Thanks for putting this up - it's inspiring. I have a lower power transmitter, Icom IC-7000 at 50W, but could put together an LNA/PA box to mount at the antennas.

Impressive that the signal will be doing a round trip of nearly 5000,000 miles.

[@goatsinker347]

5 million miles? You must've added a zero by mistake.

[@anonymousguest9290]

Especially when you calculate the inverse square law of light. How much wattage does that come to upon arrival at the moon.....and then back to base?

[@Grumpy_Cyborg]

Good job Lee.

[@tomasvojvodikom6dc403]

I'm surprised how many stations you worked with 100W. I just did my first EME with RK3FG ,at my side 100W in the shack,2x7el.DK7ZB verticaly , no preamp.73

[@g0mtnlee]

Well done. I found a huge difference by adding a pre-amp. Also it helped my 100w amplifier was at the antennas. "100w in the shack" will have some extra attenuation of course. Good Luck & 73!

[@rolandlang3590]

@@g0mtnlee What pre-amp did you use?

[@g0mtnlee]

@@rolandlang3590 Its the SP200 from SSB electronics.

What's wrong with the ft-857??? It's a great radio for any job.

[@g0mtnlee]

Yes it is a great all rounder. I only meant it's not as sensitive as a high end transverter is that the more serious ops use. But I've had an EME QSO to another FT857 in Japan since so I can't complain 👍🏼

[@goatsinker347]

Wouldn't it be better to mount the antennas so that one is perpendicularly oriented (polarized) compared to the other antenna?

[@la7dfa]

No, you sacrifice 3dB, and 3dB on EME is often no QSO or QSO. Horizontal polarisation also has the advantage of peaks in ground gain.

Cool Yagi !

Nice

Nice!!!

Nice job in Hamradio i hope you funny

Thx Lee - Inspired me to give it a go!
