Sorry, I included the wrong image. John.

Hello, ??? ??? My chart does show a 'SID' at 19:07 on 23.4kHz and 19:04 on 22.1kHz. The magnetometer shows only a minute change, but it is a single axis compared to The 3-axis on Mull. My

24kHz and 37.5kHz are weak signals here in Kent so nothing seen. 19.6kHz is fine, there was a small deviation in the signal but it did not look like a SID. I don't think I would have seen it unless I

Still lots of interesting echoes at https://ukmeteorbeacon.org/beaconclient/? showing Doppler, directional and polarisation characteristics.

Hi all, Did anyone record a SID yesterday (20th April) at 19:00? There wasn't an Xray flare from the Sun at that time, but I recorded a SID as shown on the plot but only on 3 out of the 8

I am looking for volunteers to assist with the VLF data repository project. The repository is a collection of 27,000 VLF data files currently held at https://vlfdata.org/ ( https://vlfdata.org/ ). The

Hi Paul Thanks for the reply. I am big fan of the Pico because you get a lot more performance for the money compared with the various Arduinos, despite the original ADC DNL cock-up. It's a natural

I wanted to share my sigh of relief as I complete the latest stage in my development of radio meteor detection and analysis. I think that radio meteor observers probably all interested in knowing

Hi Tony, As this is a new product, we have do not yet have a process for supplying part assembled detectors, although I’m sure we can so something for you. We will have some internal discussion

Hi Paul I know you are a board member of the UKRAA, so I am writing to ask if you know what is the status of the new Pi Pico based Muon detector. I bought two of the old (partial) kits some time ago,

Did anyone in this group participate in the? Solar Stormwatch citizen science project ? If you did, please make contact as the UK Meteor Radar project group would like to construct a project to

That sounds brilliant idea Andrew - can you send me your email address to andrew@...<mailto:andrew@...> and I will send you the link for the meeting 14 April and also put you on

Andrew, At the Norwich Astronomical Society I am running some H line observations so wondered if I should tag along to your H line group. Thanks, Andrew From: [email protected]

Hi All, I have tried peeling off the Mylar coating on two of the petals on my solar cooker parabolic reflector - and they do come off easily as per attached photos. Andy
