Where to source a uSDX+?

I would like to pick up one of these to play with, but being they’re all clones of the same design, it’s hard to tell where to pick one up. If you have one that came with the (apparently hard to source) battery, where did you get it?

Expanded TX Range ICOM IC-T10

I know there are modding guides out there for other ICOM radio's but wondering if anyone has done it to the newer ICOM IC-T10? The resource road use the land access channels in my region and looking for something more reliable than a Baofeng. I know transmitting on these frequency's is illegal, but modding the radio is not. The Japanese version of this radio has the expanded TX so it should be possible!

QSO Low sodium 20m Net?

Does anyone run a low sodium net? I'm in Southern California and hear East Coast and Central stations in the AM, and once the sun moves West I get Hawaii pretty nicely in the evening. Anyone interested to QSO sometime? 14.420 MHz?

Quick check, Is my coax being used as an antenna?

I have a vertical with radials and a coil hooked to a capacitor. The coax center conductor connects to one side of the capacitor and a tap for the coil connects to the capacitor on the other side.

The shield of the coax is connected to the antenna as well. I decided to wrap the coax in ferrite core since I knew the weather or some movement might disturb the setup.

Recently I've noticed if I touch the coax I can make signals weaken and grow in strength.

SMA Antenna in a mag mount

An experiment I'm running is taking a SO239 mag mount, throwing a PL259 to SMA-M adapter on it, and then slapping a SMA-F handheld antenna on top.

It'll put the antenna a half inch higher off the ground plane but I think it'll work? I want to get the true SWR of my handheld antennas, and also this was cheaper than getting a traditional NMO mount antenna too.

Feedback on if I'm dumb is appreciated.

Anyone know what this “radio” is? 9 channels but no microphone or speaker?

Found in a park. Any ideas what it is?

Did I fry my Kenwood TH-D74?

https://i.redd.it/152k99xz9ade1.gif

Yesterday I grabbed a random barrel jack adapter kit lying around and charged my Kenwood TH-D74A off of the same 12V (at about 14.2V) power supply I was running my rig off of. The Kenwood indicated it was charging, then not charging, then charging a few times. I gave up and went and found my genuine charger and charged the radio up. When I went to power it on, it was stuck in a boot loop where it shows the logo for about a second, goes blank for a second, then repeats. No response to the power button, and I can't get it into factory reset mode. The battery is charged and measures 7.3V with a multimeter.

Any ideas on how I might go about repairing this? I've reached out to Kenwood support, but if it really is charging related, I'll bet it's just one small SMT repair away from working condition.

Begging of Rx cut off

Hey guys. I got a cheap talkpod a36plus max radio a few days ago. I got it programmed for my channels and it's working for the most part but I'm missing the first second or so when receiving transmissions. Does anyone know if there's a setting I can change or is the radio just a pos?

Calculating PEP

https://preview.redd.it/fa0kwxlcoabe1.png?width=462&format=png&auto=webp&s=c6fa29fb67945d8b3d058b477fca4f9be3a4e774

Looking through this, Hamstudy indicates that the correct answer is 100W, but I'm wildly confused as to why.

The formula for calculating PEP appears to be pep=v2/2/r, so the problem here would be pep=((200^2)/2)/50, which gives me 400W instead of 100W.

What am I missing?

What would happen if I connected a handheld ham radio to an A99 cb antenna?

I’m curious if the larger antenna designed for a different band of frequencies would extend the range of the handheld ham.

2m and 70cm "Simplex" frequencies?

I get the band plan and the national calling frequency as far as what sections of the band to use. I ran into this last night. Was on calling frequency shooting the shit and some others were also trying to get in. My brother and I wanted to go to another frequency. How far do we want to step away from calling to have our conversation? Do we just pick a frequency or are there "simplex" channels? We also do GMRS so we're use to channel being 462.550, 462.600, 462.650, etc.

Sorry if stupid question, we're wanting to "radio" correctly. We just got out license a few weeks ago

grounding/installation help

so I'm going to build this for a portable off grid SDR setup. confused about if/how i need to ground something like this? im planning on mounting this in the upper canopy of a very tall tree in a discreet location near my campsite. also, would it would be good for transmitting? im thinking it would only need to be grounded if i were going to use it for transmitting? I have my technicians license but its been about a year since i took my test so my memory is a bit spotty on this. thanks

How do you ACTUALLY get licensed

I'm interested in getting a basic HAM license, but I have no idea where to actually start.

I've looked online, and I'm more than a hundred miles from the nearest club that does testing, so I don't want to do a 200+ mile drive only to just fail a test.

I've tried an online sample test, and just with good test taking techniques and what I remember from college Physics, I came out to just over 50%. That doesn't cut it.

I've seen recommendations online that vary from "memorize this 1200-page book" to "take this $1500 online course that comes with a free UV-5R", but I don't have the time to memorize a giant book and I don't have the money to burn on a scam online course.

How did y'all do it?

Vocational Curiosity

Full transparency up front: this post is the beginning of my research.

The Mrs got me thinking tonight and I wanted to ask strangers on the Internet for their opinions, I like to live on the edge.

So to you my fellow hammy Redditors, do any of you have experience with ham radio effecting your employment?

I know this is a hobby and not for income whatsoever but it got me thinking about being a Park Ranger and figured y'all might have something worth saying.

The floor is yours reddit, over.

Any way to unlock the QRZ 1?

Found the 4+7 menu. Any clue what the code might be? I tried the one it shows on the screen when prompting you.. Not sure if it's possible. Thanks.

Repeaterbook Question

Newbie question. I'm using a dual band HT (good antenna) and if I'm reading RB correctly then there are no open non-digital in my area. Is that correct from the info on the pic. Am I reading that right? Thanks!

Yet another two radios one antenna question

I’m thinking of setting up an APRS digipeater and was wondering if I can get away with a single antenna. I have no idea if this would work, but can I simply have a bandpass filter on the digipeater radio and notch that same frequency out on my dual band radio? Would I still somehow be risking the radios with this setup?

Finding An Elmer?

I've had my General license for about a year. Mainly interested in Uhf/Vhf. Watched tons of YT and Reddit. Still not grasping a great deal of it and am frustrated. Would like to find an Elmer to help learn. There are only a few clubs where I am and they all lean heavy into politics that aren't mine. They also just kinda sit around and chat. Not a lot of radio learning. I've tried to get in touch with area Races and Ares, but have had difficulty getting responses. Any advice on finding an Elmer that is willing to help me really learn? Thanks!

Easy to use HF transceiver? is 7300 the way to go?

New to ham, taking my test the first week of December and looking to get an easy to use HF transceiver to start with and want to take advantage of any Black Friday sales if any come up. I've seen a lot of comments saying the IC 7300 is one of the most user friendly rigs out there and I like the fact it looks like all I need to get started with it are a power supply and antenna, but is there any other unit I really should be looking at?

Struggling to find "the one"

Looking to pick up a mobile transceiver, with the following requirements;

•Detachable faceplate

•VHF/UHF

•Capable of TX & RX up to 490 MHz, along with normal ham bands

AES256 is a plus, and budget is under $2k. Anything capable of being all band modded, Part 90, etc is fine.

I've checked everything offered by Icom, Yaesu, Kenwood, and Alinco: nothing goes that high, even with mods. The Btech UV-50X3 would be perfect, if it could be modded to transmit on the RX only bands.

TIA for any help

How do people get on 40m?

Do they literally have a 20m wide half wave dipole or 10m tall 1/4 wave vertical? or can it be done with smaller more practical antennas?

EDIT: Thanks to all, got some good ideas now :)

What's considered the best BTECH / Baofeng / Retevis currently (that is unlocked, lots of channels that can be grouped, has APRS, GPS, and USBC)?

I lost my daily driver BF-F8HP somehow and need a replacement. I've been eyeing the BTECH UV-PRO but it's limited to 200 channels and watching some reviews and reading on here it looks like there's a few new offerings out there I should consider too. There's a lot out there and I'm sort of on option overload paralysis at the moment. I'm switching all of my older UV5r's over to USB C batteries so preferably it would have USB C. I would like it unlocked (Mars modded). I like APRS occasionally so I would like for it to have that option internally and not have to use a the Mobilinkd TNC. Option to turn off GPS too. What should I be looking at?

I have all the radios but I want something simple. I have the Yaesu FT3, FT5, Hytera's, Moto Turbo's, ICOMs, 878, HD2, etc etc. I recently picked up a QUANSHENG UV-K5, TIDRADIO TD-H3 and a (2 Gen) TIDRADIO TD-H8 recently. I would like more then 200 channels and be able to group them for travel and repeaters and such. I see lots of talk about the VR-N76. It's on my radar.

I flashed the UV-K5 and printed out a booklet of keys and menu options. This is way more than I was looking for. I prefer something simple.

Would like :

  • USB C
  • MARS Mod capable
  • 200+ plus channels that can be grouped
  • APRS Capable internally
  • Ability to turn off GPS
  • SIMPLE operation similar to UV5r. I don't want to have to read the manual every time I want to use this thing.
