do some weather stuff! it’s easy and it’s really cool to get signals from space. i recommend it if you’re bored of everything else and have never done it before i’m a bit obsessed and just trying to get folk to do it now

 the next net is *today* at 7pm U.K. time!I am solidly sticking with this Sunday slot now for a weekly thing since I can never make the late ones - we still need some more Europeans involved though. I know you’re out there and I want to make our side of the pond have just as strong a community as the guys here do in the US

can definitely recommend recording a chunk of HF spectrum for an hour away from all noise and then analysing it afterwards, I’ve had such a fun afternoon gonna take me weeks to go through it all - 100 GB data in total, ish. I want to try and ID as many stations as possible and decode as much as I can and upload audio clips and images and whatnot

yah, it’s worth it. I couldn’t do this at home because no outside antenna setup and huge RFI, but the kit was really portable to take out, and it was set up inside 5 mins (video of whole thing is in the tweets). I can’t believe how clear everything is - I just want to get my rig now, I want to get on the air so bad

ok, keeping track as I go: https://docs.google.com/spreadsheets/d/1-Kn1HYU7JaWKGnFhF_Bo9p1GUHMkEPtERuxZL4-GfIg/edit?usp=sharing taking a while, but so far I am doing okay at logging all the permanent stations. there may be signals that come and go and hopefully I’ll be able to set up SDR++ to let me skip back and forward in time through it there are so many stations already, it is unbelievable

cross posting from the other thread - finally got my intermediate licence through for hams out of the uk, i get: * more power * all band access * A few other things related to beacons and DF stuff MM3IIG now becomes 2M0IIG, and I will finally get more answers from CQ calls instead of people hearing the MM3 and ignoring it

setup was a laptop with SDRPlay RSP1A SDR, then a V Dipole in 120 degree angle shape, it’s like a horizontal dipole for around 2M band and below but then the arms bent forward a bit there’s a picture of the setup here, I can be up and running in 5 mins at a push: https://twitter.com/markpentler/status/1466082654588186634?s=21

Mantle posted:So if I can use a dipole, the antenna that comes with the RTL-SDR will work too? I just need to go upstairs at the right time? possibly! i am not sure what the length of the arms is though, they may not be enough for 145.8 MHz just need to arrange them parallel to the ground (so horizontal orientation) with the angle. even if the length is not perfect the ISS signal is a monster 25W so it’ll be okay. even a rubber duck on a HT works, but this kind of setup will give more consistent results. sadly though the experiment is over now so you will have to wait for the next one

i just made this over the last few days. tape measure 2/70. 5dBi gain, no reflector, total cost around £5. and i can't test it until thursday morning hopefully good for sota but mostly i want to finally try hitting an fm sat with this. in SPACE 7 watts in from the handheld, minus losses and bad tuning, i should get around 20W out? it's around 1.2 on 70cm and around 1.5-2 on 2m depending on how it flexes. i think i can trim it down more but i am so excited about finally making one for 2m  edit: yes it is held together with sticky tape

yes! hello! what do you have available to you? antenna, radio etc? an antenna for this can be as simple as a 1 or 2 metre pole with a horizontal dipole arranged in a V shape, such as this one made for weather reception, which you’d adjust the length on for the 145.8 ISS downlink: https://www.rtl-sdr.com/simple-noaameteor-weather-satellite-antenna-137-mhz-v-dipole/ but unlike weather satellites the ISS is so powerful a signal you can get away with a much less capable antenna. software: MMSSTV probably easiest. the audio pipe is the key. thehustler fucked around with this message at 09:22 on Dec 20, 2021 |

comms not really needed as long as you download all of the satellite TLE position files before you leave the house  your rabbit ears may not be long enough to make a half-wave dipole for 145.8. but again, such a strong signal it shouldn’t worry. set those up at an angle of 120 deg as the link I posted shows. short coax run to the rtl stick, short as possible while keeping it away from the laptop - maybe 5M or so? or does the rabbit ears kit have a coax attached already? i never had that so I’m not sure. if you install VB Cable or something similar that’d be the next step and then we can move onto the actual decoding software

there’s no empty carrier between images, just fully off, if that helps! you’ll just hear static heavens above is very accurate if your position info is entered correctly. they are predictions, but with some maths behind them edit: there seems to be a very tiny hump at 145.800 though, that has to be something?

Achmed Jones posted:yeah, and everyone who wants to do satellite work wants one (myself included). mantle hooked me up selling me his last year - with a fast charger - for ~msrp (iirc). this was a screaming deal given the insane current prices and i was happy to pay it. but when msrp is a screaming deal for a used discontinued radio there's something very weird going on in the market i run half duplex off one ht. it is hard. i have to wait for a signal first to dial in the aiming

ive been banging on about L-band weather satellites in the discord so I thought I'd pop up all my stuff I've received on to a google photos album because there's so much and i can't choose the best ones for the thread. also they are very big link: https://photos.app.goo.gl/KhsSwid242VhF5rw6 small sample, click for big (37 MB)  for people only on the forums I can talk about this in the other thread maybe but maaaaan so many ace pics. may get some blown up and printed edit: this is polar stuff but mervburger does geostationary! thehustler fucked around with this message at 18:49 on Dec 4, 2023 |

in the U.K. we're somewhat rebuilding the network and trying to use it to actually learn stuff, also invent new and interesting activities and links and data stuff. https://ukpacketradio.network/ map is looking p nice, but I'm down right now so my green line is gone. in Scotland specifically we're trying to concentrate more on RF links because if you do Internet wtf is the point? Green lines are RF, so the Edinburgh to Glasgow stuff is pretty well catered and I sit in the middle of that https://nodes.ukpacketradio.network/packet-network-map.html the impetus for all of this was our online club distributing about 150 NinoTNC kits

we've a few options. SO-50 is easy to work but always rammed. the Tevel satellites are relatively new and seem to be really good. strong signals. ISS also always absolutely rammed with folk. best time is daytime. less folk on and I work from home sometimes...
