Good signal from OZ4MM, example of phone (SSB) contact on 23cm band using moon reflection (Earth Moon Earth - EME). On my side 3,6m dish, 300W to OK1DFC feed and G4DDK preamp. On OZ4MM side is much more :-)
On 1.2 GHz the signal can be verifiable on your own by moving the dish a few degrees down to see if signal disappears. Ducting is possible propagation for this band obviously, but with a method mentioned above can be used to verify EME. I’m giving a thumbs up because I understand this video content.
My only phone contact on EME was with SM4IVE on 432 MHz back in the 1990's. IIRC he was using a 14 meter dish and I 4x30 ele KLM yagis, a Henry kilowatt, and my trusty Yaesu FT-726R. It was initially a CW schedule, but he was peaking S9, so I grabbed the mic and called him on phone. We completed the contact quickly using cross mode, him on CW, me on phone. lol All the horsepower was on his end, with that massive dish. Great job on doing a 2-way on 23cm! 73 de KD0GS.
Well done and no to the comment of possible ducting. That’s EME ... You can tell by the audio on the receive and the slight echo. I haven’t been involved in EME since 2010. Moved and cant put up my dish. Thanks for the vid!!
It is simple. Parabolic antenna beamwidth at 1.3GHz is so narrow that interception any terrestial signal is not possible. Lets see how much time I wait for answer after I finish my transmission. It is over 4 seconds. I finish transmitting, after over 2 seconds OZ4MM knows that I finished. He starts and after another over 2 seconds I can hear him. Its all.
Hi congratulation that is a nice ssb EME qso DX on 23cm. i will be curious to now more about your setup ? What us yoyr amplifier, coax reference and which connector and antenna distance from the shack? And how many DB about your 6 meters dish can give fir i can get an idea about PAR W... Wich reception preamp are using? I listen my transmition only one time in my life it was on 11 meter. in 1992 i listen only the end of my call... that was amazing my signal make 36000km one turn from the hearth it was my best dx that is happened to me during few minutes. Thanks for sharing.
There is no specific "the best" frequency for radio waves reflection from moon surface. Antenna is the key. Moon reflects short waves like 14MHz and microwaves like 76GHz. If antenna has a sufficient gain, narrow patern and ones use enough power there is a chance to hear own echo, hear other station transmitting (voice, morse code) or see trace of signal on the screen (digital modes). Gain of antenna, gain of preamplifier and transmitting power on both sides have to be higher then path loss.
@@sq7dqx Dzięki za szybką odpowiedź. nie chce ci zawracać głowy, ale chciałbym kiedyś mieć własny, i patrze czego koledzy używają. według kogo, np. w1ghz, w6pql ?
Qué lindo está ése equipo yo soy radio aficionado en costa rica pero no tengo dinero para comprar uno solo con mi humilde radio de 2metros yaesu.te felicito hermano saludos TI.4.J.C.G
Hi Glenn. I think there are a few Amateurs that believe the Earth is flat and the Moon does not exist. I guess they think that this QSO was fake. I was thrilled after a QSO with cosmonauts on the MIR space (QRP 5W, 1/2w dp) but an EME contact would be the ultimate buzz.
I hate to be a party pooper. EME certainly is an impressive feat. But why don't people stick to NATO phonetic? It'd make copying a little easier, especially under these kinds of conditions.
You are not a party pooper, my friend; you are a pedant. Not everybody was born in an English-speaking country; to some ham operators, certain "alternative" words make sense and are easier to hear/understand than the official words. Just like the dude in the video, I personally like "Mexico" more than "Mike" -- it has more character and strength, so to speak, so it's easier to hear it in a pile-up. Go ahead, ARREST me for this GROSS violation)))) Jeeeeez. Report me to your COMMANDER!)))
When i hear "Tokio, Oklahoma, Sugar, Bahamas" I wonder if I'm in kindergarten? Its sounds like shit!! Some kind of disrespect for me. Maybe not every one are English but if know few words to make QSO you can learn few words more to spell in NATO phonetic. Or you can read from paper. If you dont want to, then you are just lazy and you have no excuse.
@@DvorTerrier It makes my life as a listener harder when people don't use NATO phonetic. You are forcing the other guy to put in extra work to understand you because you couldn't be assed to learn NATO phonetic. Like Gotowy93 SQ9OUE said: it's being lazy. And in my opinion? It's rude. NATO phonetic is here because it makes things easier, not harder. If you can't put in the effort to learn NATO phonetic, why are you a ham at all? Isn't part of being a ham to improve your own skills? For what it's worth? I'm not a native speaker either. Hell, I'm not even a HAM operator at all and *I* use NATO phonetic. What's your excuse?
@@gotowy_sp9adc I agree, if somebody starts replacing MOST words with God know what, then it's not good at all. However, if I personally prefer Mexico over Mike (and I hear quite a few native speakers saying Mexico), I don't think I am committing a crime, or somebody's criticism is really justified. For the sake of an experiment, say Alph, Brav; now say Alpha, Bravo. Which are EASIER to read if you have a lot of QRM/QRN? Consonants at the end make the words less usable for our purpose. Mexico is a much more suitable (STRONGER PHONETICALLY!) word than Mike. Moreover, words with more than one syllable have a bigger punch than one-syllable words -- they are easier to recognize. Have you thought about that? There are MANY rules in ham radio; if on top of it we start being super-pedantic over "PROBLEMS" like Mike/Mexico, we will suck all fun out of the hobby. To compliment somebody for using PERFECT (recommended) phonetic alphabet is a great thing to do! To start giving somebody a hard time over one "wrong" word is disgusting. Most importantly, is it a VIOLATION to say Mexico, really? I don't think so. If somebody feels he is not in the mood to answer my call when I say Mexico -- fine! Luckily, there are much more normal/kind people out there than pedants :) 73, Adam! Hope to see you on the air! W1NM
