The meteor scatter (MS) is one of my favorite operations on
VHF.
My first HSCW (High Speed CW) QSO was in August 1981 during Perseides. At
this time I used
all home made equipment, included transceiver, transverter 144/28 MHz, 100 W
power amplifier
(GU-29 tube), home made programmable memory key, which gave me possibility
to transmit up to
1200 letters per minute and tape recorder with variable speed and ring tape.
And 7 elements QUAD antenna by GW4CQT.
As for a long time it was!

Scatter Logs by years:

One
of the most popular programs, using for Meteor Scatter QSO is a WSJT.
WSJT
is the name of a computer program. It stands for ''Weak
Signal
communication, by K1JT.''
The program currently supports four principal modes:
FSK441, designed to support communication using very brief
“pings” from meteor trails in the ionosphere;
JT6M, also for meteor scatter, but especially optimized for the
6-meter band;
JT65, ideal for extremely weak but slowly varying signals such as
those found on troposcatter and
Earth-Moon-Earth (EME) paths;
EME Echo mode for detecting and measuring your own echoes from
the moon.
The program also offers a Measure mode for testing Sun noise and EME
Calculator to help
you estimate the strength of your own and other stations’ echoes from
the moon.
Here is fragment of FSK 441 MS QSO (ES1RF-HB9DFG). So
easy to manage!

My
Earth-Moon-Earth (EME)
Activity is not so big.
Still I can tell only about few initials on 144 Mhz band.
The reasons are: no suitable antenna and not enough output power.
Of course, it possible to work with a "big gun" stations and increase
own results up to
few tens of initials, but as somebody says, at once: "The life is too
short to work on QRP".
In my opinion, these words are exactly for EME...
Here are
my initials on EME 2 meter band.
