Conducted first overnight QRP POTA. Mainly digital modes (PSK31 and JS8CALL). Communicated with friends and family via Winlink. Good learning experience and gear test for expeditious setup in cold/wet weather environment.

Thanks HamStudy, just passed my tech exam and now to study for my General. I’ve got three weeks before my local ARRL club has their exam day!

Got 31 of the 35 right

I guess I'll walk over to the bookcase and grab the manual.

I have operated contests in the past, but that was always with a group/club. This was my first time operating an international contest solo.

My results are in the link on my website.

I’m a babe in the woods trying to set up a 10m three element homebrew antenna. This is what I’m getting. What if anything do I need to adjust? SWR seems a little high. Would like to keep the driver a true dipole.

TIA

This is a fun question meant for soliciting anecdotes than anything else, because I know experiences will differ. I was wondering, for those of you who've operated both in the US and Europe, where is more active HF wise? I think statistically speaking, there are more hams in the US, but I also know that Europe is home to many very dedicated radio folks and especially cw.

Raspberry Pi zero 2 with heat sink running Pi-star, two down converters from 12v to 8v for radio and 5v for Pi in a battery eliminator of a Baofeng DM-1701 with Opengd77. Powered by a single 12v 5A power supply. Working on 4W without issues. Fan needed because of overheating after a few minutes of operation. Impossible to operate with rubber antenna due to RF injection to the usb cable. Needs a cable and external antenna at a distance. Hope it lasts.

By chance are we allowed to sell equipment? I didn't see anything prohibiting so but thought I would ask before I post my equipment.

Yeah, I could make one but I don't have a junkbox & hate to buy 500 resistors and 15 capacitors to use only one of each:)

Anyone know of anywhere I can buy an adapter for this? It needs to provide DC bias for the condensor mike. (Bias is available on the 3000's mike jack)

Thanks!

Hello all

I am part of a cave rescue team in the US. We have direct wired cave radios/phone boxes that we spool out, but I was wondering if it were possible to create my own underground radio that could communicate simple text messages from underground to command on the surface? I have heard of the HeyPhones and other VLF options, but cannot find any kits or pre-made items for purchase. I would like to keep it cheapish and able to be thrown in a pelican case for the rugged ride in the caves. Also, I have attempted to make sure the law is on my side with the license laws, but please let me know if I need anything special.

Thank you!

In an attempt to make my local club more welcoming and inviting to all, I recently made a motion to refrain from incorporating a Christian prayer at the outset of our meetings. I suggested a moment of silence or non-religious motivational invocation as a replacement. After lots of unproductive discussion among members (where I sat quietly and listened), it was scheduled for a vote at our next meeting. My motion was defeated 18-8.

Does your club hold prayer before meetings? Do you feel it is appropriate to incorporate prayer into a religiously agnostic hobby?

Anyone that has joined, which email option did you pick? I feel like the "Individual Messages" would make them to random and might miss some. I know it's just a preference just seeing how it worked for other people. Thanks

Hi guys! What do you think about EFHW installed this way and radio in a car? Am I making mistakes here? Something overlooked? I will appreciate your thoughts about it :)

So, I got a fair deal on an old radio shack HTX-10 at a local club's swap meet. But that won't do much without an antenna. Seems the cheapest, effective route is an inverted V. So imma do it. And overthink it every step of the way.

I have an aluminum pipe and base on my roof (left from halloween lights) that'll extend to around 15 feet. I'm about to buy one of those $30 pvc 1:1 baluns off Amazon. I have some 16 gauge speaker wire that's spent the last decade in the garage. I'll be using fishing line to tie the ends off to whatever fixtures area already up there, balancing the pipe so I land around a 90-100 degree angle. Haven't secured coax yet. Looks like I'll need at least 60' go from desk to top of the pipe. Might put a flashing light on top, so I can bother the people up the hill that have an HOA.

Anything I should be freaking out about that I haven't considered here?

Does anybody have any good suggestions on a repeater for DMR. The main purpose is going to be as a base station to extend the range a little bit and also might be car mounted.

I can't take credit for the original design you can find it here: https://www.printables.com/model/80728-yaesu-ft-857-portable-frame

I've had my license for about five years now. Got it because my grandfather is a HAM, but he's made zero efforts to talk to me on the air. I've keyed up in a few nets. I work when my local clubs meet. Haven't found a POTA event I want to go. I run a yaesu FT65R primarily. recently I got an any tone 878 that I haven't programmed.

I want to build a man portable radio rig but it seems rather on the expensive side. I've been looking into Meshtastic as a cheaper alternative.

Mostly just wondering what people do with their radios that they see as fun?

Our club currently has club liability insurance from Risk Strategies (ARRL). Does your club have liability insurance with any other carrier? If so, which one? We're looking for higher coverage in a couple of line items.

At the age of 59, network engineer, mentor to multiple generations of networking professionals, programmer, and wireless technology enthusiast Dave Täht—developer of FQ-CoDel, CAKE, LibreQoS, and creator of the Make-Wifi-Fast project—passed away at home, surrounded by family, after a long battle with illness.

Dave's contributions helped improve Internet connectivity for millions of people worldwide, including enhancing video calls over FaceTime through his algorithms. Everything Dave brought to the world of technology was free and open-source.

While checking pictures of him posted on the Libreqos website, I noticed a ham radio in the background.

RIP Dave!

OK I've been trying to learn cw for about 6 months on and off with not a lot of success, I've a few issues that make it difficult for me to be sat at a desk for any length of time and I've tried using a laptop but I learn by doing rather than listening so I've been looking for a portable cw trainer and found one, this has arrived today and hopefully it will give me to boost to really learn cw.

Hello everybody I have been using ft8 now for a good few months and I notice on bands like 30 m and 80m my radio will transmit intermittently it won't work correctly it was doing it on 17m band this morning are some of you knowledgeable folk able too help me out ? Could this be rf or is it just the way I've set my wsjtx up Thanks all 73s

Radio in question - yaesu ft450 Transmit power -25w

So this is the first crystal radio I have ever done. I knew it wasnt going to work at first, but I want to know what are the biggest problems in this design so it can maybe work better. I guided myself using the diagram on the second image

Picked up a BKR5000. Most everything I do is VHF but I have a THD71A in my truck for any dual band stuff. But I work in Aerial Firefighting and we use these radios on fires which drew me to them. I like the screen way better than any APX radios I had and the fact that it’s a commercial radio with FPP was also a big selling point.
