  1. I think I'd have a divorce on my hands if I put up a monster like that 😂
  2. Well, I've had the system up and running 24/7 (mostly) for just over a week, and I'm pretty pleased with the counts.
  3. Certainly seems weird that they're so far off. I've got button labels using now and time It's annoying, because I had about 4-5 days of data and my actions were using a mix of time and now - so the times between log entries, and filenames for captures etc. don't correlate properly and it took a while to find time to properly investigate. I've sorted everything out and using 'now' throughout.
  4. From the documentation, I understand that the time function: returns the time when the last line of the waterfall (FFT) has been calculated. Depending on the scrolling speed, this can be different from "now". The unit is the same as for "now" (seconds elapsed since 1970-01-01 00:00:00.0 UTC). and the now function: returns the current time (including the date) in the internal format of the program, which is a combination of date plus time as a floating point number. Does anyone know why these functions return such greatly different times? I would expect it to be only a few seconds difference at most? (or have I missed someting). Example, now: 2020-08-12 09:11:00 UTC time: 2020-08-12 06:55:22 UTC
  5. @Stormchaser, thanks for the feedback... I am really liking spectrum lab, so I think I'll go for a cheap 2nd hand laptop. My home network extends to the shed and garage so it could run scripts to move the data logs to my NAS periodically. I know what you mean about streaming. I am running one at the moment and it does drop from time to time, that's on a laptop with an i5 2.5Ghz processor, 8GB ram and an SSD. But I don't really intend to run that all the time. More for fun at the moment as we go through the Perseids peak. I am an amateur radio licence holder and this is getting me interested in trying meteor scatter communications in the future. Uh-oh, I see another rabbit hole opening up 😂
  6. I am running a stream from my detector too in Hampshire. The stream does go down from time to time.. I think the laptop hasn't quite got enough oomph to reliably run spectrum lab and stream via OBS to YouTube at the same time. Anyway, it is on my channel here when it's running. I do check periodically and restart the stream when needed. https://www.youtube.com/channel/UC9UOXkk28mj7QcuO_qVQuqw PS. Is this a meteor ping? If it is, are the spikes due to the azimuth scanning of the radar beam?
  7. Thanks for your replies. Having searched the 'net, I figured this would likely be wishful thinking. Time to buy a 2nd hand PC or laptop for the shed then
  8. Hello all, I've finally got round to getting up and running with a set-up for GRAVES radar meteor detection and what a learning curve I have been on in this past 7 days! I have built a 3 element yagi out of plastic pipe and a steel tape measure. Nice and cheap, but not really suited to permanent installation as the electrical connections aren't weather proofed and the elements would flex in the wind. But nice and portable to take out to an observing session. My longer term plan will be to build one with more robust and weatherproof construction. I started out using CubicSDR on Linux with my SDRPlay RSP1A and was very pleased to get pings. I put the audio (via VB-Audio virtual audio cable) into Argo which could screenshot the waterfall every screen full and I got some great catches all through the night a couple of nights ago. Yesterday, I have been experimenting with Spectrum Lab and using the MetScatV7 configuration and conditional actions to capture and log the pings. Ultimately, I would like to have an SDR and Raspberry Pi running 24/7 in the shed, so my question is, has anyone got any experience/recommendations for a Pi based solution like Spectrum Lab! Thank for reading
  9. Example of an SSTV image received by a friend of mine yesterday
  10. Looking for advice/recommendations.... I have a QHY5II mono camera and a set of 1.25" RGB filters. I'm thinking of dipping my toe in the water of RGB imaging and would like a filter wheel to make life easier without spending mega bucks. Wondering if the cheap(ish) manual 5 position filter wheels are a good purchase or not. Any advice /experiences/recommendations would be appreciated. There are a lot of Chinese (I suspect) models on the market around the £50 mark, are they worth a punt or should I avoid and go for a recognised astro brand? Thanks for reading this, I look forward to your replies.
