The activation of the 46 metre Algonquin radio telescope by VE3ONT in 1993 and 1994 produced tremendous signals off the moon on 144MHz. Listen to VE3ONT calling a VK1 (33KB).
The loudest signal out of Japan on two metres EME has to be JL1ZCG. This was recorded using a home-brew SCAP audio filter at a bandwidth of about 40Hz (86KB).
My own echoes from the moon on two metres recorded just after moving up to four yagis in 1994. Mind you, conditions were very good at the time (44KB).
But you don't need big antennas to work EME. Here is W5UN heard on a single yagi in 1992 (34KB). Here is Dave again, (19KB ) this time heard through a narrow audio filter.
With only two yagis, stations like DL8DAT (43KB) and SM5MIX (20KB) are easily workable. One interesting EME contact made with two yagis was with VK3AMZ (29KB). Note the higher pitched meteor ping 2 seconds into the clip and the same characters "VK" repeated 2.5 seconds later off the moon. BTW, I have now worked VK3AMZ by tropo scatter, meteor scatter, aurora and EME. Is this a record?
And for the very latest in EME, here is a screen shot from a JT44 EME contact with GM4JJJ (36KB) in April 2002, using Joe Taylor's superb WSJT progam. The shot is GM4JJJ's reception of VK2FLR using just one yagi on the horizon. The picture was created by playing two .WAV files through the program to show two transmissions from VK2FLR. The date on the screen is the date the picture was created, not the date of the contact!.
The first (62KB) signal at -15dB is just audible but the second (62KB) signal at -22dB is not.
Meteor Scatter
The Leonids meteor shower in November 1998 produced some great contacts on 144 MHz. Here is VK4KK (13KB) working VK2TWR and VK4IC (14KB) working into VK1 and again (11KB) into VK2.
The 2001 Leonids produced a meteor storm over eastern Australia with zenith hourly rates peaking at almost 3,000 between 1700 and 1800 UTC on 18 November. Over 80 stations from VK1 to VK7, ZL and YJ8 were heard or worked via meteors on 144 MHz that morning. Some of the loudest signals in Sydney were VK4BLK (25KB), VK4ABW (50KB) and VK5NY (62KB). The VK calling frequency on 144.100 ran hot with pileups (58KB) during long burns, when DX stations were louder than the locals. Another good signal was VK7MO (48KB) in Hobart, about optimum Es distance from Sydney. Amid the 144.100 QRM, it was often difficult to decide who was working whom. Here is VK2OM not working VK3CAT.
Low power beacons such as VK3RGL (43KB) were consistently audible during long burns.
But you don't need to wait for meteor showers to get get contacts. Joe Taylor's WSJT software raises the probabilily of completing meteor scatter contacts on 144 MHz to almost 100% - on random meteors. Here is a screen shot of VK7MO (37KB) working into Sydney on an average morning.
And this (13KB) is what it sounds like.
Oscar 13
The Oscar 13 Mode B downlink heard on 8x8 crossed yagis. Here are DC6AK (25KB), I7UGO (21KB) and UA0DG (43KB) in 1992.
Tuning across the downlink passband often sounded just like 20 metres on a good pass (74KB). The Oscar 13 telemetry beacon on 145.810 (17KB).
