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

you know of any osx software that'll do the needful? a rec for a noaa sat tracker would also be dope you also need a RHCP antenna (not related to the band that is bad and i will die on this hill) right?

This doesn’t help your situation but its currently the start of a new solar cycle and very occasionally we get the boost from mr sun. your good for like 11-12 years if you start a HF station right now. also re: station location. Im spoiled now because I live at the very top of a large hill and I have a baby vhf/uhf antenna on the roof and it works amazingly well. I can do 2 meter simplex with people on 5watt handie talkies 20-30 miles away. further if people are on 50 watt mobile radios Its going to be a sad day when I relocate and dont have much choice in geography.

my RTL-SDR V.3 and antenna showed up today so now I've got the VHF antenna next to the window and I'm skipping through various bands trying to find interesting stuff. found my first weird thing, a station at 169.440 MHz that was sending out regular, short pulses like so: then it stopped for a bit before sending out a few long pulses at various intervals. it doesn't sound like anything on AM and sounds kind of like a mechanical ratchety sound on DSB -- zoomed in they look like this:  my guess is that this is a digital signal and that I need to find a plugin for SDR# that'll do DMR e: currently listening to a bunch of old dudes on a repeater chatting about fuel injection. the air waves are fascinating Kazinsal fucked around with this message at 05:57 on Aug 7, 2021 |

i got my 9450. it's bigger than i thought. it is currently playing groove salad. the raspberry pi is running a lil sinatra app to let me change stations, add new stations, etc, HUP the process when it dies. this doesnt really happen on SomaFM stations, but some broadcast fm stations control the "this is CALLSIGN supported by listeners like you!" message by just making it play at the start of every connection and HUPing that every hour. also sometimes when i open tmux or whatever i guess that causes the process to get evicted from meory (lol) the ruby bindings for my SSD1306 don't actually seem functional at all. i tried the golang bindings and they didnt work well either. might end up doing a separate python process if i can get hte display to work how i want it to. i might also just not do that and leave it alone the tone control on it is kinda scratchy and everything is a little muffled until i get it into just the right spot, and then it doesnt generally hold. it's fine-ish for background music but i wanna fix it. i got a service manual and i dont think i want to mess with disassembling it and replacing the tone pot, but im hoping that a squirt of deoxit will fix me up with minimal effort it's funny bc my reason for not wanting to gently caress with it is bc im afraid ill strip the screws. once it's open the soldering on something of this size should be a piece of cake, but actually getting it open without messing it up makes me a little nervous. i have stripped a lot of screws in my life. this is also why i didn't open up my game gear and recap it myself - i couldn't get the screw to turn on the first couple of tries and didnt want to push my luck. i fuckin hate phillips head screws is what im saying the xf-4 that i got (and is on its way) is a tube radio, RIP probably

don't worry about the screws on the back. they're just coarse thread wood screws, very easy to work with. i modified my 9450 with an external AM antenna input, i can clip a long wire on to a terminal in the back and pull in even more stuff. deoxit should fix that tone pot.

holy poo poo against my expectations i got both my deoxit and my tube radio in the mail today. i popped the back off of the sony 9450, gave the tone pot a squirt, and now it's a fuckin dream. sounds great, looks great, is great the RCA Victor XF-4 works almost flawlessly. It doesn't sound as good as the 9450, but it is a tube radio without frequency correction that was made almost 20 years prior. the dial reads 2-2.5 mhz below what it's actually tuning, which is a pretty easy fix but I'll probably not mess with it, at least for the time being. i'm so stoked to be listening to modern radio on these things. so rad i'd pretty much written off the xf-4 as a cool shell/restoration project. to have it arrive _just working_ is insane to me

fuuuuuuck yes very nice my content: i took a radio break this week but ordered a $20 mag mount antenna to slap on my roof flashing for a dedicated APRS antenna, which let me hook my big vertical back up to the 9700 and i can play on repeaters again. woo

i decided on a mutually beneficial policy of "stealth mode, and also nothing's permanently attached to the house" item 1: here's the APRS antenna. it's there. can you find it?  item 2: my homebrew HF vertical is pretty stealth and you can't see it from the street  item 3: my dual bander is pretty stealth and you can't see it from anywhere

drat that's sick. I have a little two foot long antenna that sits in my living room window and I can listen to the local ham guys on VHF and the VE7RPT repeater through it good conversation last night about maintaining turbodiesels, wish I had my license and could participate

can you describe what's going on with your dual bander? i see the magloop and then above it i see a wire coming off of the second central pole going towards the left, and then a little bit off to the right (where it looks like it crosses or something) e: and i just found the radials above the magloop. but i thought radials normally went on or in the ground. does putting them there set up a higher groundplane or something? and if so, why would that be a good thing to do?

yeah the radials on VHF antennas are generally at the feedpoint. they're just providing a roughly 1/4 wave long radiator for the transmitted RF to 'push against'. for big HF antennas, the radials are often ground mounted, but in that mode their length isn't really that important; in that type of installation, they're actually forming one plate of a giant capacitor. THE EARTH! is the other plate. And that's what they use to push against. This is why ground mounted HF works with the 'more radials = better than' guidance. more wire down means there's more surface area for the top plate of the capacitor. for VHF you can get good counterpoise action with just three or so. btw, the loop below the dual bander is just a cheap FM broadcast receive antenna. works very well and they're built great for $30.

lol the cord coming out of the top right is the AC adapter e: this thing requires perfect polarization, by the way. I could kinda barely hear the tune, but when I make sure that the pi antenna was actually vertical it comes in pretty well. not at all like the radios, which pick up the signal just fine when i throw the pi and its antenna under a shelf. I was literally holding the antenna, which was supporting the pi's weight, with my toes to keep it vertical while I took that
