    That should be enough, what you really need to worry about is that thing hitting trees and getting tangled in random stuff. A spring mount would help with this a lot, I used to have a small (20") 2m antenna on the handlebars and it was always getting fouled...

    Sure, you can run ladder line all the way but it is a little lossier than open wire feedline. Ladder line should be spaced at least 4 inches away from anything metal or wet. Electric fence standoffs make good spacers/insulators.

    ok, i am a bit paranoid about lightning safety, as i should be. my feeling, during a storm, i would want to completely disconnect, 100%, from the antenna. but how much of it is paranoia? hypothetical situation: if i had some sort of tower for my antenna, i would want at the very least a lightning arrestor (do these things actually work?), and i would want a switch of sorts to disconnect the antenna, and ground it. how safe is the feed-line from the Ham Shack, to the disconnect at the base of the antenna? i would disconnect it from my radio whenever i am not using it (and during a storm), but is it safe to have the cable entering the Ham Shack? I know lightning looks for the quickest path to ground, but with that much current, would it not also travel in the cable to the Ham Shack? my thinking is to disconnect the inside cable, and get it outside, where lightning belongs. sorry for my paranoia, i have been holding it in for a while. ;) ~Travis

    Hello great Ham Radio Gurus! I am in need of your wisdom! I have been a Ham for a few years now and am starting to branch out into the homebrew world. The current project is trying to build a bike mobile set up for public service work. An aging neighbor has given me several antennas. Three of which were mobile whips in 2m, 20m, and 40m. Here are pictures of the 2m variant that I wish to use.

    I am going to make a doublet antenna and have been deciding on feeder type. I was going to make my own ladder line which would be a run of about 35m from antenna connection point to entrance to shack and then change to 450ohm Ladder Line to enter the shack and connect to atu. My question is why change to open line why not run whole length with ladder line which would be much simpler and neater? The run will be down side of house then run along bottom of fence, under decking to opposite side of garden and along bottom of fence again to centre mast and up to antenna connection. A second question is running with open line or ladder line resting on the floor under decking going to cause a problem? Thanks in advance

    I thought I'd compare the US questions with our specification for ham radio. The similarities and differences are quite unusual. Q2 - no UK equivalent to this one. Military comms and amateur stations not a feature of ours. Q3 - international goodwill is odd too - ours is to do with self-training. Q4 - picket fencing? We usually refer to this as flutter. Q7 - seems amazingly simple, when to do one of the others, you need Ohms law and resistors are mentioned there! Q9 - this one we'd get right here I think. We'd probably use RCD rather than GCI Q11 - we don't have any link with radio control kit at all Q12 - towers are not a feature of the exam here. Climbing them would come under a totally non-amateur set of regulations. Q15 - Oddly, we don't have any exposure figures here - we do have them in general advice to all people, but not anything legal or linked to licences.

    Hi Team, Please can someone help me with an issue programming my new Hytera PD565 radios? I have a number of Hater PD565 Handhled VHF Radios, one by one they have been damaged by water/general abuse over the years so I Purchased 4 new PD565 radios. The old radios are running firmware version A5.06.05.000 but the new radios are running version A7.06.01.007. I want to programme the new radios by cloning the programme off one of my old radios but due to the different firmware the CPS cannot read the old radios.

    NICE! I never got higher than an 80 on the practice - then I aced the exam with a 100%. You are GOOD TO GO! I think your proposal is MORE than reasonable and along the same lines and spirit of what I was talking about.

    Hi folks, I used to have my Kenwood D700A installed in my pickup truck, going from the battery through to a fuse distribution panel mounted to the floor. This was relatively straight forward. In my current car, I have high-end Rockford Fosgate amplifiers to drive good quality speakers in the door. This installation already has heavy gauge cables running to the battery with a fuse inline (I have to check the gauge but it looks like 10). I don't anticipate running the stereo at any significant volume levels while transmitting at the same time (for numerous reasons, such as power draw and the fact that you can't have music playing in the background while transmitting, by FCC rules), but also I want to be able to filter out noise from either the power amplifiers or from the radio. I was thinking of installing the Kenwood main unit under the driver's seat (the Rockford Fosgate amps are under the passenger seat) to separate the coax away from power interference, but at the same time the ground and power...

    kd0vey replied to a thread Age Old Antenna Question in Antennas
    I hope this isn't too late to help. I have a Hustler 5btv vertical on my metal pole barn roof and a 4btv that I take with me when I camp. Both work fine on 10-80m. A tuner is not needed. From what I have found the 4btv does not need radials when mounted within 2 feet of the ground. The 5btv uses the metal building as a radial and works a lot better. But I wouldn't notice the difference without going from one to the other while testing. Oh, both need a 1:1 balun to reduce the static. The air choke suggested in the installation manual did not help much at all. When in a park I sometimes put a flag on the 4btv to raise it in stealth mode.

    How about an alternative: those that have proven that they intend to take, and have the ability to pass the exam, and use the knowledge responsibly, can move on to full member. I just took this practice test while i was waiting for a response (printed directly to PDF): http://tjfserver.ddns.net/misc/tech_practice_exam.pdf actually, i find it to be my personal best score. perhaps a fluke. ;) ~Travis

    BINGO! You, sir, are the kind of people I LOVE to interact with. Creating the Sand Box would still give you access to interaction and an avenue to ask and research information. Don't get wrapped around the axle on the name - We could call it the Elmer's Corner. But I'm just looking for a way to filter out good people like yourself from people that are looking for a hall pass from a ham radio operator like "this guy who is a licensed ham said on the internet that I could use the Baofeng on police channels and it would be OK..." But they aren't looking to immerse themselves as you have. They really aren't interested in obeying the law so much as they are looking for a loop hole. Ask yourself this - Why would you join a Ham Radio forum to learn about non-ham radio communication when there are already GMRS forums, CB Radio Forums, Cell Phone Forums, et al. If you wanted to know about GMRS or PMR Radio, why not join a PMR Forum? I'm not on here asking about pottery and fine china because it is out of...

    what about people like myself? i don't have a license yet, though i fully intend to get one. but i am fully responsible enough to not touch the PTT button, until i have a license? I am just doing my research to have things set up correctly and responsibly, so that when i have my license, then and only then will i push the PTT. I would find it offensive to be stuck in a "kiddy pool" until i get my license. the action would also likely drive me away from even wanting a license anymore. ~Travis

    Considering our friend, young PetrolHead hasn't posted up since July of 2017, I decided to go on a bit of an electronic journey and assemble a larger picture. Here is his first post from June 25th: https://www.hamradioforum.net/threads/7805-Hi The context of which leads me to believe he is not licensed and the term "petrol" while used in the USA is not a common reference. We call motor fuel Gas or Gasoline. This would indicate he is either a UK based member or that he is a more refined American. The second post of PH is the one we are discussing and reading here, dated June 25th as well. Third, on July 1st he posted up this thread: https://www.hamradioforum.net/threads/7816-Baofeng-uv-82-Not-working

    Not legal in the U.S. either. I have a UV-5RA, and it requires at least a Technician license. But race car events bring in the big bucks, so they might be ignoring it.

    paulears, I agree. While some local hams don't care for the cheap radios, I like mine. It does what I want. Its not my $500 HF rig, its for 2 meters. I use it for the bicycle race in May, and 1 to 3 times a week for our local 2m chat net.

I am very disappointed of the reviews I see of the fmrs and gmrs walkie talkies. Many people say the range is poor. I am looking for something with good range and minimal licensing requirements.

    Hello, and welcome to the forum. Google is often your friend here. eham has honest reviews, and I found this when looking through their site:- http://www.eham.net/reviews/detail/912 With regards to moving fowards, I don't think you can do better than to join a club. You'll get lots of hints, tips, assistance, and advice on what's right for you, as well as training (not all clubs) on the exam content.

    In the UK this would be illegal without a commercial licence. "Domestic" PMR is freely open to use unlicensed, but radios must:- be channelised; have a maximum output of 500mW; have a fixed antenna. That said, the powers that be don't seem interested in pursuing misuse. Kind regards,

    Hello everyone! So I'm not sure where to start. I am brand new to the Ham Radio world, like I have zero knowledge or experience about this equipment but I bought a radio at a auction today and thought it would be something interesting to do. So first I'll tell you about the radio I purchased. It is a Icom IC-375A 220MHz SSB CW FM transceiver. It is brand new in the box. It came with the manual and microphone. I haven't looked through the manual yet, I wanted to come to the net first and talk with people who know and love Ham Radio. So Im just looking for anything you all would like to share or tell me. Tips, tricks, dos, don'ts, etc. Also any comments on this particular model I have. Is a good model, common or rare, worth anything, reliable etc. In case you're wondering, I paid $150 for this model. Was that a fair amount or did I over pay? I guess that about sums it up for the most part. I don't want to make the post too long where no one wants to read it. Thanks in advance to everyone who...

    Hello all, Greenhorn here! Been studying for my Technician exam for ~10 days... went to a race car driving experience today and all of the crew were on BaofengUV-5Rv2+ radios. I explained that I'm studying for FCC/Ham license exam and was psyched to talk about the process with them, well they looked at me like I had 2 heads. The guy told me nobody at the track is licensed they said all of the teams use them.....what am I missing here? Is this legal?

    If it is well designed, like my IC-756PRO, the tuning light will blink when it can't achieve a match and it will automatically reduce the output power until the reflected power is below the maximum dissipation allowed.

    Hello. New to forum and Ham ... Been studying ~10 days for my license and went to a Sprint Car driving experience today. All pit crews were using Baofeng UV-5Rv2+ radios (20 guys). When I mentioned I was studying for my license and ask them about the radios they all looked at me like I was crazy. They said that every team and every pit crew use them and no one has ham radio licenses. Am I missing something or is this illegal? Sent from my iPhone using Tapatalk
