@M0YNG https://forums.radioreference.com/threads/radioshack-discone-antenna-question.383983/ looks like a relevant thread on the topic suggesting blue loctite, good to know it's a tried and tested method
@M0YNG TIL, obviously I've seen this stuff but never knew what it was. I think perhaps that might be suitable, I imagine the wind vibration is what's causing them to work loose, hopefully it won't drop any more before I get to fixing it
Only a few weeks into the winter weather and my discone has already lost an element to the wind. Access is challenging so going to be a while before I can get it down to fix. All the elements were tightly screwed in though so I'm not sure what more I can do, perhaps add a bit of PTFE tape around the screw thread? #hamradio #antenna
@jeff I did mine through the BBADL course, it's a big course with some bits you will find dry but having a strict schedule to keep up with really helps imho. There's also lots of videos online to go over topics that maybe don't click from the course book, Dave Caslers YouTube series are really good, they are for US extra but there's a big over-lap in content with both being CEPT licenses.
After months sat up on the roof doing nothing, I finally hooked up my HF discone to where I need it and ran some FT8 monitoring tests overnight. Considering propagation is supposed to be garbage, I was very surpirsed how well it performed. Never seen so many contacts over the pond with my previous efforts, just a shame I cannot tx with it too. Receiver was Airspy R2 with Spyverter.
@M0YNG totally naive at this but 21.4 * 21.4 = 457.96 so perhaps this is how the end rx frequency is achieved with some kind of tunning capacitor. I'd guess you'd need to swap the xtal out with something around 20.8MHz to hit the 70cm band
First test of my discone after mounting it outside the loft was a mixed bag. Reception improved all over but 2/70 still absolutely dead, though I can get a reasonable reception of the only local repeater I can reach now so that's something. Next step is to get my transmitting aerial up and put out a call to see what comes back.
@Elodie hopefully you can overcome the setup issues, I know fldigi isn't a best designed interface but it is flexible and once you get it set up the way you want you'll be picking out the faint dx signals as good as anyone.
@Muto never tried it but looks like you can
@M0YNG Xiaomi Mi A2. Worked well for me so far
@Elodie have you tried using digimodes like psk31? It's ideal for hard of hearing hams without having the barriers to entry of CW.
@kr4dio unlike that one, I don't think mine is resonant on any ham bands. Even if I can tune it up it'll probably not be a very good radiator. I might try some day but it wasn't intended for tx anyway.
@kr4dio it's commercial (https://www.moonraker.eu/scanking-hf-discone-0-05-to-2000-mhz-antenna?___store=english). It is about 6 feet tall. I suspect the top section conceals a coiled up long wire or something but didn't fancy dismantling it before first use to find out. I doubt it is as effective as the full size model but it lets me scan the full range of my Airspy+Spyverter without switching antennas so it's a decent solution.
@DC7IA I was probably about 14 before we got even dialup internet so I land in the Xennial demographic of people who grew up offline but we're online as a youth. I worry about my son growing up without that perspective, I think it was a good thing and maybe why I have an easier time than some to just leave my phone behind or #deletefacebook. I don't fear a world without as I lived just fine before the Internet
@DC7IA I think having a coordinated but voluntary day of disconnect would probably be a good thing for public mental health. People might try out picking up the landline and calling family for a change and find something in it they were missing
@mm6lvl yeah, I reckon a lot of hams read/write-for hackaday and they are nothing if not opinionated 😀
@mm6lvl bit odd the author undermines his own authority right at the start by saying how he's inactive basically since getting licensed. Doesn't really fill me with confidence that I'm getting a peek into a deep well of tribal knowledge
@DC7IA it says a lot about the British psyche when a guy who's channel is largely about riding around the London train network has over 100k subscribers. I can't stop watching...
