    As I understand APRS (subject to correction by other here) the primary and most popular use is using it to encode your geographic grid coordinates and sending that data out so you can be plotted on a map or located. But that isn't the ONLY use. You can set up (on other frequencies other than the Geo Location Freq's) your own system to relay E-Mail, images, or other data via APRS. Essentially APRS is a way of modulating and demodulating digital code (1's and 0's) over the air waves to move data from one radio to another. So if you are in a remote cabin and you want to send your sister an E-Mail, a small e-mail, you can queue it up, transmit on a designated frequency to someone who is also on that frequency and has their 2m radio with APRS modem hooked to a computer to report that data. That data might be non-geolocation specific such as but not limited to: weather water levels in a lake river flow rates ground temperature near a volcano Your blood type

    Update: Alas, all the aluminium parts in the connector had corroded to the point where a slight twist simply cracked the bolts when trying to remove the coax. Add to that several cracked directors, cracked plastic parts holding the directors in place, and completely rusted together nuts and bolts holding them together, I decided that it just wasn't worth it. A replacement isn't that expensive new, and I'm sure something will crop up used at one of the local clubs' "bring and buy" or auction evenings. I'm in no hurry. The rotator is being very stubborn. None of the bolts will shift, despite liberal doses of WD40 and numerous attempts with sockets and spanners this afternoon. So I've sawn off the mounting poles at each end - the 6" losses on them aren't too hard to bear - and will take it down to the garage run by my neighbour. He's got the gear required to remove this sort of thing. If it comes apart and is OK internally, then I'll do a complete refurb over the summer months, a bit at a time. Paul and...

    In the UK, it is each licensees responsibility to ensure that emissions are within the amateur band, and significant output outside the amateur bands could be subject to fine or equipment confiscation. I suspect that none of the FCC out of spec Baofengs have significant output in the bands above or below that with the small antenna cause grief. Of course milliwatts into a proper antenna could be a problem - couldn't read the link above got a 404. I bet many home brew transmitters are less clean than the Baofengs. I'm NOT a supporter of them, but you have to admit you get a hell off a lot of radio for the money. I note the poster copied and pasted the message here on a few forums and got no response there either - one example here http://www.radiodiscussions.com/showthread.php?702236-UV-5R-won-t-work&p=6150915

    ARRL has performed spurious emission testing on several HT brands over several years. Here are their results for Baofeng: 2012 - 13 units tested, 31% compliant, 15% borderline, and 54% non compliant 2013 - 41 units tested, 49% compliant, 15% borderline, and 36% non compliant 2014 - 67 units tested, 10% compliant, 33% borderline, and 57% non compliant 2015 - 65 units tested, 25% compliant, 21% borderline, and 54% non compliant For comparison Yaesu, Icom, and Kenwood tested with only Yaesu having 1% non compliant and Kenwood having 2% non compliant. Non compliant means they don't meet FCC specifications. Baofengs were the worst units tested.

    Panic job came in today - somebody wanted an urgent pile of extra radios for an event that had been misorganised. In the workshop was a cardboard box full of Baofeng radios that I had charged a few days ago with the intention of selling them on ebay. My van was out on a job, and the usual hire stock was in the back. I plugged the radios in, stuck the same single frequency in each one, added 4 cheaper dPMR handsets, two MD-380s and a couple of Icons, and sent the lot out. The event is less than two miles away, and while working I've been listening to the chaos. One thing was very apparent. I could NOT tell which radio was which. Clearly there were small tonal differences, and annoyingly one of them was chirping when the PTT was released. I'm not going to sell them on ebay now as I got more for the one day hire than I'd have got selling them. Some are cheap and cheerful, some are water resistant and some have torches (for Gods sake!) but I can hear all of them from here, and I really must stop knocking...

    People like to look down on Baofeng / Pofung for reasons like: 1. Cost 2. Support 3. Build Quality 4. Audio Quality 5. A LOT of End Users / Operators that are "Paper Hams." And while all of that is true and fair game, lets not forget our first bicycle. It was small, had training wheels, tassels on the handlebars, and probably some superhero theme that you wouldn't be caught dead riding today. Baofengs are the same way. It is the training bicycle of the Ham Radio world. I've got one. Cut my teeth on 2 Meters with it and learned a LOT about Amateur Radio. Would I ever buy one again? Oh hell no. But do I regret buying the last one? Absolutely not.

    Programming a Baofeng without software assistance is not for the faint-hearted, it would seem. Reading the (ahem) owner's manual didn't help. I was lucky in that a friend had programmed a lot of useful frequencies into his UV5R, so I just used his settings as a template and then amended, deleted and added as required. I think the welcome message was intended as a 'security' feature to deter theft - a stolen one would have to be re-programmed to remove the true owner's ID. But if there's a quick and easy reset feature on the radio itself it would negate any benefit. I think the Baofengs are probably so cheap that any out of warranty failures / 'oops' moments would make them almost 'disposable'.

    I didn't know that. I looked at Chirp but I needed to connect my Baofeng to the PC. Can you fill in the information for the Baofeng without connecting to the radio?

    paulears replied to a thread Yaesu FT-902DM Receive in Yaesu
    Pile of kit? Tranceiver, tuner, antenna, cables, odds and ends........ 4 or 5 feet is an odd size. The key will be in the driven element. It will be a simple dipole, or a folded dipole, and if HF, would need traps to make it resonant if it's that small. A 2m yagi - 2 elements and above would have a width of around 3 foot or so - so yours might not be a ham product at all, could be a broadcast band VHF radio antenna? This would also make your impedance measurement with the test gear make a bit more sense. Broadcast is usually 75 Ohm impedance, rather than our 50. At that size, I'd guess it's not HF at all - so you need to do a bit of research. Your tuner is actually quite nice, and is capable of tuning almost anything to be something that matches - but it doesn't mean it's much cop as an aerial. If you shove a random length of any old wire strung up as high as you can get it - between trees, posts, gutters etc, you should be able to receive something if the radio works - failing that, Google your local...

    Remember WD40 is also a real horrible substance to get rid of when it's done it's job - electrically it is not a good conductor, and it's presence on the surface inhibits corrosion, so needs cleaning off with something else - a solvent that evaporates rapidly works pretty well. Something like a Dremmel is good with the brush attachments to clean corrosion off.

    APRS will not work with subaudiable tones, there would be too may collisions. The subaudiable tone squelch only mutes incoming signals that don't have the correct sub-tone. The whole point of packet radio (in general) is that the channel is effectively "shared" by shaping your transmit delay etc, whereas sub-squelch effectively ignores everything making timing irrelevant.

    If the call sign is available, I'm sure there are other things you need to do like prove he is your relative. Or if it isn't in use, you can get a free call sign upgrade, once you get your license, to a vanity license. Such a vanity license used to cost, but they did away with that.A And welcome to the forum ! License tests are now given by ham radio clubs, and not the FCC.

    I don't know what you mean by a pile of ham kit. I'm not ready to take the test yet, i have much to learn before then. This ham equipment was my grandfathers and he has since passed. Unfortunately he passed before i was old enough to ask him all the questions i had about ham radio. I have seen yagi's are large but the antenna i have looks very similar in structure to a yagi, but about 4 or 5 feet wide. I am a field engineer for a power company and i deal with carrier equipment, and we call the device we test levels with a signal generator (but it is technically a communication analyzer). It has a SLM meter, signal generator, impedance meter, VSWR meter, LCR meter, frequency response analyzer, and an oscilloscope built in. Anyway i have just a simple antenna analyzer. Sorry for the incorrect terms used. I just figured i wouldn't need much of an antenna just to listen to HF signals, but it sounds like i still need to find a proper antenna just to listen. Thank you for your information!

    You may not renew his call just to keep it active. That would constitute fraud. The only way for you to keep it active is to take it yourself as a vanity call. Normally, when a call expires it does not become available to the vanity pool until the two year renewal grace period has expired. Then it becomes fair game for anyone. Relatives of the former holder are exempt from the two year period and may request the relative's call as a vanity at any time as long as they can furnish proof of death. The FCC database shows your father's call as still active with an expiration date of 11/19/2017. If you wish to request your father's call before it expires, then you will have to furnish proof to the FCC of his passing. A death certificate will usually suffice. You then may request his call as a relative of the former holder.

    If the exterior of the house is stucco (which we have a lot of in Southern California) then there is wire mesh underneath the stucco. This will really degrade the signal. Also, if the house is insulated with batt that has a foil side to it, that's also going to degrade the signal.

    Baofeng UV-5Rs are so cheap that to repair one would probably cost more than buying a new one. And this gives you a perfect opportunity to upgrade to a radio with a better feature set and ease of programming, like a Yaesu FT-60R...

    I put a Chinese Wouxun antenna on my Yaesu FT-60 and it doesn't screw down all the way. It makes perfect contact and the radio operates fine. I just filled the space by adding an O-ring at the base of the antenna. I just have to be careful not to lose it if I take the antenna off and it has to be replaced periodically because they deteriorate over time.

    You're asking in the wrong place. You need to be sending your inquires to Yaesu, not asking the ham community at large. It's just the way they programmed the firmware in the radio. I have the same radio, as do lots of others, and we all have the same issue. Just yesterday my APRS interfered with a contact on a repeater because I had accidentally moved the B band off 144.390 (the national APRS frequency) and it was beaconing on the repeater. I realized it right away and change the frequency back and then apologized to the other hams (who are both members of my club) so no real harm done.
