Below is a carpet plot produced in Microsoft Excel that shows the hourly meteor counts recorded during July / August 2023 from the Raspberry Pi 3-based receiver at Brough Astronomy's Observatory (BLAS). These were post-processed on my development system at home. This shows the "overdense" meteor reflections received from the GRAVES radar in France and probably correspond with those that were probably visible with the naked eye, albeit over the Mediterranean!
I now have the Notice of Variation to run an APRS Gateway MB3UNN from my home QTH in North Newbald, East Yorkshire. This gateway will provide the connectivity for the proposed digipeater that will be co-sited with the GB3NY UHF repeater at High Hunsley - The reason for the oddball frequency is due to both my QTH and the proposed digipeater being close to the restriction of 50 km from TA 012869, Irton in Scarborough, specified in Schedule 2 of the Amateur Radio Licence.
It's currently running receive-only for test purposes, using a Raspberry Pi 3B with an RTL-SDR, piping the RTL_FM audio into Direwolf, it will be upgraded to full operation using a single band 2m radio following further test and evaluation.
Work in progress: creating Python code for the Raspberry Pi at Brough Astronomy so that I can add a second radio receiver to provide the much needed audio for a true "multimedia" experience watching meteor showers.
A short break from work gave me some time for more experiments using WSPR over the Easter holidays from my WFH desk with a Raspberry Pi and Yaesu FT-817.
I first tried using a Clansman E-VHF sleeve dipole which happens to work rather badly on 30m and 17m and then with a Maldol 40m mobile whip operating at ground level in the garden.
The meteor radar detection system at Brough Astronomy is based on a Raspberry Pi and low cost USB Software-Defined Radio dongle. Despite it's small size, it is able to receive signals and distinguish between meteor echoes and the erroneous signals from satellites such as Elon Musk's "Starlink" constellation.
Over-dense echoes, caused by meteors with a mass that is greater than 1 mg, result in an ionised trail that persists over several seconds and occur in a daily peak associated with the earth passing through the meteor stream.
Whilst the rapidly decaying under-dense echoes, caused by the background of meteors with a mass less that 1 mg, appear to follow a sinusoidal pattern that is caused by the Earth's rotation into the meteor stream.
These graphs explains why meteor showers are best observed in the early morning before sunrise when the population is greatest - for more information see the presentation that was given to group's monthly meeting.
My Yeasu FT-8900R configured for a North Humber Raynet communications test on both 6m (with CTCSS set for compatibility with the Clansman military radios) and for the UHF Raynet repeater located at Weedley Farm in the Yorkshire Wolds.
