Oh awesome, my plans are almost exclusively DMR/D-star/echolink! I got my AMBE3000 dongle before I even took my test; the first thing I do once I get my callsign is gonna be to register for the digital networks (if there's links I should read, please hit me with em!) I don't know enough to prefer one digital format over another, but if there's stuff going on over DMR, I'm there! I'm also interested in sending TV/image signals (on whatever frequency or network, SS or FS I'm not picky) cause that's awesome. And I want to build a transceiver, because I like soldering and that's cool. I'm not super interested in things that require big antennas because given my living situation, that would just be setting myself up for dissatisfaction.

Are we lowly GMRS licensees that just paid $70 and didn't take a test allowed in here? I have questions about protocol. (If so, I'm WRJL415) Also, lol, my father was an Army radioman in Vietnam, when he got home he just got the most basic license for CB (back when it required a license) when he got a job as a truck driver, because it was cheapest. Even though he could've got the highest-level HAM license. Chillbro Baggins fucked around with this message at 06:53 on Sep 27, 2020 |

For DMR you will need a DMR ID, which you can get from http://radioid.net/ which will require some documents to get verified; I don't remember what all but I think it's just the original copy of your license which you'll receive from the FCC. This step can take anywhere from a few hours to a few days. Once you get your DMR ID, you'll want to sign up for https://brandmeister.network/?page=register which provides access into the DMR network. Then once you have that, you're good to go. Probably a good idea to hop on our discord so we can help you get everything setup. We hold a net on DMR TG 3163563 every Tue 8PM PT and Fri 6PM PT (subject to change), and we're always happy to have new people running netop.

Do you HAVE to have an “ID”? If so, why? Is it to access gateways and the like? Can one just key up on DMR simplex with their callsign and that’s fine? Edit: also is your callsign embedded in the outgoing signal a requirement (for whatever country folk are in - I’m UK)? I’ve seen people talk about that too.

I don't think there's any requirement anywhere to have a specific DMR ID for a simplex transmission, you'd obviously have to ID yourself like any other transmission. Most traffic is on the network systems and they require an ID which is associated with a callsign. Some radios will transmit a short ID string with every PTT - this feature is relatively new (IIRC added in a 2012 revision of the spec) and optional. I don't know if any of the low cost radios have that feature. Hyteras with a relatively new firmware support this feature (and will display it when receiving a signal). Motorolas don't support this (or didn't as of 2019 at least). The brandmeister network will add text for you when going through the repeater network if you enable that option in the self care page. E: the feature is called Talker Alias longview fucked around with this message at 18:31 on Sep 27, 2020 |

DMR is a reappropriated commercial system so the concept of 'radio IDs' comes from there. over in cop land the tech room would set your radio id to UNIT 37 HANDHELD or something like that; over here you use your callsign. you can just make one up if you just want to chat simplex with a buddy but if you get on Brandmeister or whatever with a fake/made up ID you're going to piss people off and might get banned under that ID.

OK, I have my AMBE3000 and my DMR ID, and I registered for D-Star. Now, is there any OSX software that'll let me connect to brandmeister? I know there's EchoHAM for Echolink and Buster for D-Star, but I can't figure out anything other than running BlueDV in a VM for DMR (this isn't really possible because my laptop is rather old and does not really have the space for a Windows install). Any tips? I have a linux server that I can install software on, but actually using it as a workstation is a non-starter because as it's headless and I want it to stay that way.

Congrats, you received Radio Marti, a pro-capitalist/American propaganda station that we fireball blast all over Cuba! Only 7335 or 7365 are real transmitters though. The ones up on 14mhz are definitely images or phantom signals your SDR is picking up.

I did that a few months ago. HamExam.org to study https://hamstudy.org/sessions to schedule an exam I just chose a date that was convenient for me, with a club that was local to me at the time, but I hear people are just scheduling them wherever, since it's all remote anyway. They are very stringent about inspecting your examination area for outside materials during the exam. Most people recommend using a laptop in your bathroom since that'll be the easiest room to make clearly empty for the examiners to see.

the milk machine posted:Has anyone here done a technician exam online or can recommend an org? I just did that. I took the one administered by AA7HW. They asked if I wanted to go for my general, but I didn't attempt it. Pretty much all tests will have the "keep going" option since they all use the same testing site. There's no need to use a laptop in the bathroom if you can guarantee that no one will come into the room. You just show off the room with the webcam, do a 360 with it, show your desk, and then take the test. If somebody comes in the room, it invalidates the test. I'm married with a four year old and have my desk in the living room but was still able to get 20 minutes to take the test without having to hide in the bathroom lol. The room doesn't have to be empty by any stretch- you just have to take papers and random electronics and poo poo off your desk.

Is there a multi-band CW QRP rig to be had for less than 200$? The closest I've found to what I want is the MTR3 but it's $300 (acceptable) and always out of stock everywhere. I got into amateur radio for CW and got very proficient over the course of a year, but have yet to buy a transceiver. I ordered a pixie kit but I think my soldering skills weren't up to par because it doesn't work -_- I was thinking about the MFJ QRP cub but ideally I'd like a display to show the frequency I'm on. Also looked into the QRP labs QCX but I am hesitant to buy a kit that might not work for that price - I only have the most basic tools and no mentor to guide me through a build. Any ideas?

The QCX+ has way more room and shouldn't be too bad as long as you're careful about it and check your connections. Also the QCX mini is due out eventually with quite a bit less soldering involved.

I just built a 20m QCX+ and can confirm it was fun. Go check out the instructions online-- they are the most comprehensive, detailed, easy-to-follow I've ever seen. There's also a fairly friendly online community that will help troubleshoot, and diagnostic tools are built into the radio. They are mono band, but at ~$50 for the kit you could buy 4 with your budget. It's a good performing radio too. If you're interested in portable though, definitely wait for the QCX mini in about a month. Still the same software and still 5w output, but literally fits in your pocket.

Silly question perhaps, but I have no SWR meter or antenna analyser, but I’d like to make sure I’m pulling my telescopic antenna out to the correct width (it goes longer than 2m half-wave so I need to stop before the end). If I use an SDR stick on the same frequency to monitor as I extend and retract the antenna, seeing when the received power is at its greatest, is this a decent approximation? Also, do you start measuring from where the loading coil stops when someone says “extend to x inches”?

The telescopic I’m testing I bought fifteen years ago and have no idea on who made it. It extends to about 126 cm so I shoot for 95-100cms when I use it on my HT on 2m.

Gotcha. It might be a half wave, or might be set up for a 5/8 wave. They made both kinds. However the half waves were a little more popular. The SDR is likely going to get its front end maxed out with any signal you transmit within a quarter mile, so I'd just say to set the whip part at about 38" for 2 meters and go hogge wilde. So, you're right about on the mark. It's not like you're going to lose 20 dB of performance if it's a few cm off.

Excellent, I’ll not worry too much then. When I set the HT to 50 milliwatt *with no antenna attached* and hit the PTT the entire visible 2MHz of SDR bandwidth on screen lit up.

# ? Oct 4, 2020 23:45 |

I literally run my DMR hotspot at 1 milliwatt and have a 50 ohm 1/4 watt resistor jammed directly into the SMA antenna jack, and it still overloads my HT when i'm 30 feet away. Near field RF is several orders of magnitude more than a decent radio usually sees.

Here's a few more stupid questions: * Can I put that 1/2 or 5/8 wave telescopic on the end of a length of coax and get it up high? Presumably yes if it's 1/2 wave, no if it's 5/8 wave due to the lack of a ground plane? * (Assuming the above is a bad idea) If I use a fiberglass pole to get something like a flowerpot antenna up high while already on top of a mountain, is that going to be any significantly better than said telescopic attached directly to the HT? I'm often amused by how much sitting down vs standing up matters, so I assume any amount of height will work better for VHF line of sight signals? But standing up vs say a 4-5 metre pole? Hmm... Essentially it's whether it's worth the extra weight to actually make my own antenna and use it in anger like that. I don't drive so I don't do mobile use, and I live in a ground-floor flat so I can't really improve that with any antenna really. This is just to help me with portable/hiking use. thehustler fucked around with this message at 16:46 on Oct 5, 2020 |

look into the rollup j-poles. they're super compact and though theyre not self-supporting you can hang them from a tree, tie them to a stick, whatever. Extremely popular for portable and sota stuff. Talked to a fella on a mountaintop this weekend who was using one with an icom 705 the whip you have is best used attached to an HT. you could finagle a base and ground plane for it but it's not built for that kind of duty
