Comments by "Peter S" (@Peter_S_) on "Ringway Manchester" channel.

  1. Could you please comment on how it might perform for listening to NOAA weather satellites on 137 Mhz? It seems a very intriguing option instead of the typical SDR in a box.

  2.  @c128stuff  Thanks. Satellites add the challenge of Doppler shift and I've heard comments about the selectivity of DSP radios being less conducive than standard PLL tuners. A small kit like this seems fairly ideal for bringing on a hike to good spot.

  3. Absolutely brilliant series! I'm hoping for and looking forward to the Eric B interview!

  4. Hi Lewis, I sent you a mail about a week ago about your woodpecker blanker if you'd like a schematic of it.

  5.  @RingwayManchester  I was crossing my fingers that you would cover the NRQZ. Thanks for all the excellent information.

  6. Interesting bit of kit, especially as they'll get around a substantial number of issues which made UHF radios difficult to deploy for one reason or another.

  7. I see it between the Ringway Manchester channel name and the 🔔Subscribed menu just below the video on the left side.

  8. I own a cheap QuanShang, but it's only ever been tuned to NOAA and METEOR satellite frequencies.

  9. Archer Space Patrol... I recall having the slim 49 MHz units with no morse key, the bulkier units with a code key and legend on the front, the big boxy base station which was also a shortwave and CB receiver, and the headsets which were grey with orange foam with the grey belt box. 49 MHz was great fun. 73's

  10. No, this was obviously contractor work for the U.S. Government.

  11. Read up on Inverse Fast Fourier Transforms and you'll have all the answers. It's just a spectrograph in revere. To see the data all you need to do is perform a spectrograph to convert the sound to frequency bins. To encode an image, you start with the frequency "bins" and treat them like the pins in a dot matrix printer. Put noise at the frequencies you want pixels and nothing where you want blank. Mix the tones for a whole row together and transmit a line.

  13. Very enjoyable series. 👍

  14. Very nice to see the plug for SaveItForParts. 👍 Ringway Manchester and SaveItForParts are two channels I stop everything else to watch.

  15. I would worry far more about the nuclear fuel fabrication.

  16. This is from a press release about the facility in 2003 and might clear it up a bit: "MATIC is a 32,000-square-mile range where the military will test frequencies, radios and other aspects of communications networks, using the mesas and hills around Laguna Pueblo to simulate battlefield conditions for short-range radio equipment"

  17. Starting with a Pi and an SDR dongle will allow you to perfect your antenna + filter and/or LNA setup before you upgrade your receiver.

  18. They're test transmissions to see how well radios mounted on military vehicles are able to receive them. Слава Україні! 🇺🇦🇺🇦🇺🇦

  19. If you're not transmitting and on a budget, there are a myriad of options in the $20-$30 range to be had. The cheapest popular option might be the BaoFeng UV-5R but beware there are a great number of very similar and sometimes performance-wise very dissimilar radios all called BaoFeng UV-5R. Buy from a shop with customer reviews. Seems the largest issue with these is some of them have monster amounts of harmonics on Xmit and are quite dirty. Lots of design revisions result in lots of different performance levels out there under the same name, but they're still worth every penny for a cheap receiver if you ask me. Ditch the stock antenna and upgrade that part to boost the performance.

  20. It's a trip to look out the window of your car and see the same hill in person. Today it's covered in grape vines and no longer looks so blissful. It's on Highway 12 in Sonoma County, California.

  21.  @jbb-cj1md  Calculus gets hairy very quickly but I thought of an easier way to describe it... Have you ever seen 'how to play songs on piano' videos where the played keys scroll up the screen as a series of parallel vertical lines? This is the same, just pushing the notes needed to create a picture.

  22. Interesting bit of kit. You seemed to have intuited the focus technique; in a TV studio the procedure is to go to maximum zoom, adjust the focus, and then frame as necessary.

  23.  @fjb4932  I'm certainly not asking, just saying 'Seabee on a MSC Oceanographic Research vessel in early '70's' makes me think of words like Glomar.

  24. ^ This answer 100%

  25. I was thinking something likely similar. If you could use the same SDR apps with this kit rather than a generic SDR it seems worlds ahead.

  26. Try listening to some Boards of Canada.😉 Corsair, Gyroscope, and possibly Telepath.

  27. Brilliant!

  28. Climate change is very real even if you stick your head in the sand like an ostrich. July was the hottest month on Earth in the last 120,000 years. Watch some climate spirals; they're so simple to understand that even 5 year olds can understand immediately.

  29. It's 'ph' for both words. I've been around since the colored box days and I've not seen 'f' used for both words ever, but to each their own.

  30. Just a point of note: I worked for a property manager who converted a small apartment building to smart meters roughly 10 years ago and the GFCI in the bathroom closest to the meters would trip every time the meters transmitted. I don't have any knowledge of the radios or power levels in use in that instance. A grounded piece of wire fence mesh was attached to the building side to mitigate the GFCI issues.

  32.  @cplcabs  Try using your noggin a bit, eh? I see a number of use cases, mostly small business, but you declaring they're "pretty pointless" only shows your understanding is "pretty limited".

  33.  @cplcabs  Do you need others to do all your thinking for you? Seems it.

  34. Are you familiar with NAFO, the North Atlantic Fella Organization? 😂 Search YouTube for 'TVP World NAFO' or 'Bonk vatniks, get medals: Russia irked by NAFO Fellas | Edward Hunter Christie | TVP World'

  37. That's really not even remotely as clever as you think it is. It's a dumb person's witty joke. It also shows you don't know anything about military history.

  38. Coastal defence on the water is the purview of surprisingly, the Coast Guard. The Army handles the land portion. The area of the AN/FRD-10 I grew up near was also served by multiple Coast Guard radio stations. A Coast Guard member at one of those radio stations did the gardening which resulted in the 420 counterculture number.

  40. These channels have periodic data sent over them. The buzzer stops for a cycle, the data is sent, and the buzzer resumes.

  41. Mossad has been known to perform similar tricks with car batteries where there's enough volume for explody stuff to cause a serious bad hair day.

  42.  @RingwayManchester  Absolutely. It was excellent and it covered the technical elements I had hoped for. Addressing the impedance of the mounting entry is the level of detail which makes this channel shine.

  43.  @jbb-cj1md  Try a search for "Canon in C - Johann Pachelbel - Full Speed" including the quotes and the channel PIANOreader came right up with an example. Rather like the scroll from an old style player piano. The principle difference with with the field analogy is that here there is a plow for every line in the field, and all plows operate in parallel with each one represented by a unique note. Any number of notes can be played together to create marks of the desired shape.

  44. @tripplefives1402 I've been writing FFTs and other DSP code since 1988. Yawn.

  45. @tripplefives1402 You can stop being a plonker now, if you're able, which I seriously doubt. I said, "Read up on Inverse Fast Fourier Transforms and you'll have all the answers." I didn't say the simplest implementation is X. I'm guessing a lot of people call you pedant under their breath.

  46. @tripplefives1402 Along the way to the big picture there are innumerable learning aids which describe every aspect as a sub piece in terms which are digestible to the individual at their individual level. If you don't know what the destination is, you'll have a harder time getting there. Once you have a hardware MAC unit, this all becomes rather mundane and is easily accomplished today on Chinese microcontrollers costing less than the pre packaged condiments at your favorite establishment.

  48.  @eTexNerd  Being able to spy on your adversaries is good in wartime. Buzzer channels do occasionally stop for a cycle or two where messages are sent. Messages which are most likely military.
