PERSEIDS 2021

ANALYSIS OF PERSEIDS METEOR SHOWER 2021 on 144MHZ
on my monitoring station

After some time of inactivity in meteor scatter i switched on 11.august 2021 my actual monitoring system to
144.360 MHz in MSK144 and 144.174 MHz FT8 mode to see what is going on in 2021.
All received spots were sent to the PSK31reporter page for visualisation of the results.

receiving was done on my 3 antennas for 2m with the following setup

ANTENNA 1 - big wheel about 8m AGL
RX1: 144.174 MHz FT8 WSJTx 2.4.0 + Linrad on RaspberryPi2
RX2: 144.360 MHz MSK144 WSJTx 2.5.0-rc5 + GQRX on Odroid C4

ANTENNA 2 - 4el shortyagi (0.95m long F9FT modified)
on balcony beaming 275 towards UK

RX1: 144.360 MHz MSK144 WSJTx 2.4.0 + Linrad on Odroid C2

ANTENNA 3 - 10el YAGI (DG7YBN design) on TOWER 9m AGL
beaming to SPAIN QTF:225

RX1: 144.360 MHz MSK144 WSJTx 2.4.0 + Linrad on Odroid C2
RX2: 144.174 FT8 WSJTx 2.4.0 + Spectravue on Windows

!A NOTE BEFORE ABOUT!
i have no good takeoff to the NORTH->EAST ->SOUTH
some mountains with up to 10 degrees of elevation from QTH
so the complete NORTHERN,EASTERN and SOUTH EASTERN
direction is very BAD ... you can see below ...!

RESULTS OF FIRST DAY 11.AUGUST 18:00UTC to 12.AUGUST 18:00UTC
12aug 18ut -24h

monitoring MODE MSK144 144.360 + FT8 144.174 - maximum hrd distance (MSK144) EA4I 1901km

RESULTS OF SECOND DAY 12.AUGUST 18:00UTC to 13.AUGUST 18:00UTC

monitoring MODE MSK144 144.360 + FT8 144.174 - maximum hrd distance (MSK144) EA4EJR 1924km

RESULTS OF DAY3 13.AUGUST 18:00UTC to 14.AUGUST 18:00UTC
ON DAY3 i got in the morning of 14.august additionally to the MS activity some
"TROPO LIKE CONDX" to FRANCE and NORTH of SPAIN ...

but maybe it is done by an meteor peak outburst ? .... look here

or here (updated 25.aug2021)
https://www.iprmo.org/flash/perseids-2021.html
on 144.174 MHz in FT8 so it looks on my receiver in this time

so 2 pictures of longtime analysis...one for FT8 only ... and the second for ALL (MSK144 and FT8)

monitoring MODE only FT8 144.174 - maximum hrd distance (FT8) CT1EOD 2051km

monitoring MODE MSK144 144.360 + FT8 144.174 - maximum hrd distance (FT8) CT1EOD 2051km
