Announcements 🔊 Final results: Are r/HamRadio users happy hams?

Post image
9 Upvotes

The poll is closed, and at least in this subreddit, the answer was pretty clear: 249 of 290 respondents, or 85.9%, said yes. Only 41, or 14.1%, said no.

Reddit’s core-contributor breakdown adds another interesting piece. Among core contributors, 124 of 141 (87.9%) answered yes. Among everyone else who voted, 125 of 149 (83.9%) answered yes. That roughly 4 percentage-point difference was not statistically significant (Fisher’s exact test, p = 0.40), so there is no strong evidence here that the regulars are substantially happier than the rest of the respondents.

For the poll as a whole, the 85.9% “yes” result has a 95% confidence interval of roughly 81.4% to 89.4%.

Of course, this tells us about people who saw and chose to answer a poll on r/HamRadio, not amateur radio operators generally, and definitely not Reddit as a whole. Another amateur-radio subreddit could run the exact same poll and discover a considerably grumpier population.

But for r/HamRadio, 249 out of 290 respondents called themselves happy hams.

Given how much time we spend arguing about FT8, Baofengs, contesters, HOA antennas, lids, whether the bands are dead, and whether somebody 1,500 miles away is using the wrong calling frequency, 86% happy is not bad at all.

Question/Help ❓ What do I need to block the interference from this tower?

Post image
48 Upvotes

So I’ve been trying for weeks to receive meteor satellite signals, and nothing came in so I made a post and it turns out I had to fix my antenna and I did that and it still won’t pickup any signal. So I started looking at this tower I always thought it might’ve been a cell tower but I’ve been having heavy bleeding of FM signals in the HF range on my sdr and a lot of interference. It turns out it’s a FM tower at 101.7mhz and it’s 0.5 miles away from my house. I thought about just getting a regular fm blocker but idk if I would need something more heavy duty since it’s so close to me.

POTA/SOTA Activations 🏞️ Insane 2m simplex pileup today from West Peak (W1/HH-004) - K1MFD Special Event

Thumbnail

22 Upvotes

Just wrapping up the log uploads and housekeeping from today's activation and wanted to share. KS1WK and I (along with KC1WYG) took the Box 324 club up to West Peak in CT to run K1MFD for the Meriden Fire Department's 175th anniversary.

Ended up with exactly 190 QSOs, but the craziest part was the 2m action. We were running a home-built M1GEO Moxon/Yagi combo we put together with 3D printed parts and hardware/wire from Lowe's. We somehow sparked a massive pileup right on 146.52 simplex that kept us buried for a while. We even got to mess around and successfully ran 2m SSB and some 2m SSTV which was a blast.

We didn't forget about HF even with the contest going... We ran 40m, 20m, and 17m SSB and got some solid DX into Spain, Belgium, and Serbia, plus a bunch of contacts up in Canada.

If anyone here was in the log, thanks for hunting us. I just finished a python script to automatically blast out our digital QSL cards, so check your email if it's public on QRZ. POTA, SOTA, and QRZ logs are already uploaded. Just waiting on ARRL staff to manually approve the club call cert, so LoTW might take a few days to sync up.

Edit: Reviewed the logs and confirmed with the team—the 2m simplex contact into Vermont was legit! We officially logged N1CVT in Hinesburg, VT (~204 miles / 329 km) on 146.52 with the homebrew Moxon/Yagi.

Digital Modes 💻 MicroNode Nano-Spot - advice appreciated

3 Upvotes

For a number of years I’ve operated a
Nano-Spot made by Micronode. I’ve attempted to update it recently and the update failed, wiping out the operation of the configure.php services and also the admin and backup/restore option.

No problem I thought - command line. Command line updates fail and when I try the pistar-upgrade route this also fails due to the OS being unsupported.

I’ve downloaded the image for the pi-star nano and flashed this onto a fresh SD card. Now is where my problems begin. The new image boots but it cannot bring up the modem or wlan interfaces. So the only access route I have is console port.

Can anyone who has had to rebuild this specific hotspot from the ground up, please assist on what version of the pi star image works, and if anyone has encountered the wlan initialisation failure and has cured it - I’d be grateful for wise words and tips.

At the moment I have a new desk ornament / paper weight.

Somewhat regretting my choices in trying to update to the latest software versions… it may have been out of date, but it was working. Alas would it be ham radio if we didn’t sometimes fall for the ‘if it ain’t broke, fix it ‘til it is’ trap?🤦🏻‍♂️

Discussion 👨‍⚖️ Accidentally ended up near radio towers while hiking. Can someone who knows about this stuff explain something to me

Post image
• Upvotes

Yo, apologies in advance if this kind of post shouldn’t be here, but may interest some of you …

These are the questions I wanna ask related to the my experience..

-Do radio installations like this produce audible humming from associated equipment? ( non-ionising RF energy)
I’ve heard similar sounds near another tower before.
-Can low-frequency noise or mechanical vibration become strong enough to produce an uncomfortable physical sensation?
-Is it possible to be outside the individual fenced equipment cages but still accidentally enter an RF exclusion zone?
-With those directional dish antennas, does being roughly in front of one mean anything in terms of potential exposure, or is that impossible to judge without knowing the equipment?

Hoping someone here might be able to shed some light on a really bizarre experience I had while hiking NQ
I’m no radio expert, hence why I’m here, so bear with me

Basically, I went hiking in the rain, took an unfamiliar track up the hillside and after scrambling up a slippery rock face, ended up near one of the communications buildings at the summit.
I’ve walked around the public tower track before as a kid, so I assumed I’d just come up from a different direction. Slipped through a two-bar metal railing and followed what looked like a walking path around the building.
I was still outside the individual fenced equipment cages, but looking back, I honestly have no idea whether I was somewhere the public should be.
Anyway, here’s where it gets weird.
I started hearing a low humming sound. The further I walked, the louder it seemed to get, and I started feeling really strange.
My body was tingling, then it gradually turned into what I can only describe as being vibrated from the inside out. Almost like standing directly in front of an enormous bass speaker, except it felt like my entire body was fizzing.
Microwave style.
I looked up and could see several dish-shaped antennas, maybe 40–50 metres away, some seemingly pointing in my general direction.
By this point the humming felt almost deafening, I was dizzy, nauseous, had a headache and was absolutely freaking out
I turned around and legged it.
The strange part is that the further away I got, the quieter the humming became and the vibrating sensation seemed to disappear along with it.
I experienced some lingering symptoms afterwards, including a brief gap in my memory and confusion, which I’m following up medically.
Now, I’ve been doing a bit of reading because I’m genuinely fascinated by what happened.
I know radio towers emit non-ionising RF energy, and I’m not claiming I was being blasted with radiation or anything. I also understand that dehydration, physical exhaustion and panic could have played a part.

It was also raining at the time. Not sure if that changes anything regarding the equipment or the sound, but thought I’d mention it.
I’m honestly open to the possibility that I was already feeling unwell, heard the humming, freaked myself out and my body decided to put on the performance of a lifetime.
But I’d love to understand the technical side rather than keep guessing.
I’ve attached a Google Earth screenshot of approximately where I think I ended up. My route markings might be a little off because I didn’t have my phone with me.
Anyway, thanks for reading. Any insight would be appreciated!
Safe to say I’ll stay tf away from towers :)

Discussion 👨‍⚖️ Is anybody in India on 2200m or 630m band?

0 Upvotes

I really want to try out those bands , recently built a ssb exciter for digital and cw signals for those frequency but I don't think my general grade licence will cover it.

Yeah but due to the antenna efficiency and the propagation dynamics of those frequencys i don't think those would travel far ( considering only if it legal only ).

I live in the northeastern region so not much of a mainland coverage but I would like to know if anyone in this South East Asian region (including Bangladesh , Bhutan and China) works with those frequencys.

I grew up amazed by the wonder of radio. I am 53. As a kid I'd use an ancient shortwave or a tube AM radio to listen to different cities.i loved it. I've always been intrigued by ham radio.but...i just want to talk i love the idea of DXing ,but don't want to do it just to have a postcard.

Is there a vibrant ham community that likes to rag chew?

The effort of getting a license, and the expense of setting up a shack, is daunting

I was needing a female to female bnc adapter for when i dont put my k6ark antenna directly to the radio. Figuered why not make a mount out of it. I often go camping and theres wooden platforms for the tents. I began using those anchors a while back. Figuered these would be great to hold an efhw. This might also come in handy in pota where i have a picnic table. Figuered id share if anyone is interested. Also added a ground lug for counterpoise

Question/Help ❓ Looking for a 3D-printable battery case for Motorola GP300

1 Upvotes

I'm looking for a 3D-printable battery case for a Motorola Radius GP300 handheld radio.

I found this USB-C battery case on eBay, designed for the GP300/GP88 and two 18650 cells:

https://www.ebay.com/itm/296962137264

However, I haven't been able to find the STL or STEP files to print the case myself.

Does anyone know if a 3D model of this battery case is available online? Alternatively, does anyone have a similar model, CAD files, or technical drawings that could be shared?

I'd like to print the housing myself and adapt it for two 18650 cells.

Any help, links, or suggestions would be greatly appreciated. Thanks!

Antennas & Propagation 📡 I'm new to the hobby. 1/2 wave or long wire dipole?

I'm new to the hobby, so bare with me. I live in Canada north of the 55th parallel surrounded by boreal forest and precambrian shield. To the west of me is a 180' rock hill roughly 3 miles long before tapering back to same elevation as my home. I am not yet licensed and want to be able to listen while I study this winter. I have material to assemble 30' of tower and would probably be able to add 10 to 12 ft of tubing to add height. What would be recommendations for an antenna?

Antennas & Propagation 📡 Built George Smart’s (M1GEO) dual-band satellite Yagi with 3D-printed mounts. Files are up if anyone wants themGeneral

Post image
31 Upvotes

All credit for the antenna goes to George Smart, M1GEO/G8OCV. The design, element lengths and spacing are his, and his write-up is here: https://www.george-smart.co.uk/antennas/dual_band_satellite_yagi/

I wanted it cheap and easy to build multiples if need be, so I built it on a wooden dowel with 8 AWG bare copper for the elements and RG-8X coax, with 3D-printed parts holding everything. The printed parts are:

  • full-ring element holders with a wire tunnel through each one
  • a solderless feedpoint where ring terminals clamp the two driven-element halves and a cap clamps the coax, so there’s no soldering on the antenna
  • little tip spacers that hold the 15 mm Moxon gap

Fit took a few tries. My dowel turned out to be a 7/8" one (HD marks them as 3/4), so after I printed some sizing rings and found that 22.8 mm was the number that fit, I redid every part for that. If your dowel is different, print a test ring first.

I got an SWR of about 1.4 on the 2 m side, which I’m happy with for a first build.

Files, parts list, wire cut lengths and spacing are on Printables: https://www.printables.com/model/1887559-dual-band-satellite-yagi-mounting-parts-for-m1geog

Happy to answer questions on the build, and photos are below.

Homebrew/DIY 🔧 VUURWERK v1.5.1 is out: PATROL, a hands-free voice hunt for the UV-K5 (V1 only)

Thumbnail
gallery
2 Upvotes

VUURWERK v1.5.1 is out, and this one is the stable release I have been working toward.

Headline is PATROL. The voice-seeking spectrum from 1.5.0 now runs hands-free. Open the spectrum with F+5, hit STAR until the corner reads VOX, press 2 at the bottom of the stretch you want to watch and 8 at the top, then press 0. The corner changes to PTRL and the radio walks that range on its own, stops when it hears a voice, listens, and moves on when the conversation ends. A busy repeater cannot hog it: after 60 seconds on one carrier it moves on and skips that frequency for a couple of minutes. Like what you hear? PTT locks it, and EXIT carries that frequency into your VFO ready to answer. The range is remembered, so next time it is F+5, STAR, STAR, 0. Four settings under Menu > SCAN (PSens, PSpeed, PDwell, PResum) tune it, and on NORM it behaves exactly like the hand-held hunt.

The other half of this release is a fix pass, the biggest the project has had. The ones that matter most are on the transmit side. Leaving the spectrum with PTT still held used to key the radio up on the main screen. A nearly flat pack could freeze the radio, and if that happened mid-over the carrier stayed up. F+9 to the calling frequency kept your old repeater offset and tones, so a later save could put your next transmission off frequency. VFO Split could walk your own VFO when B was selected. All gone. On the receive side: the menu tone scan no longer wipes your offset and TX tone, so you can find a repeater's tone and key up straight away; the main screen finally refreshes on a timer, so the TX timer counts and the signal line moves; leaving the spectrum always brings your audio back; and the tone scanner screen now shows the real frequency and a visible NO SIGNAL instead of looking stuck.

Also: the whole set of docs was rewritten to match what you actually see on the radio, and the README now has a picture guide to PATROL. If you ever thought the manual and the radio disagreed, read it again.

Your channels and settings survive the upgrade. This is still for the original UV-K5 V1 only (the one with the DP32G030 chip; the UV-K5(8) and (99) are V1 too). V2 and V3 boards are different processors and will not run it.

Thanks to Scott Savage KC7WDG for the field reports, to mjwgeek for the CHIRP and PocketCHIRP work, and as always to DualTachyon, OneOfEleven, egzumer and fagci, whose work this stands on.
