    Hi everybody, I'm pretty new to the field and I came across a strange frequency. https://soundcloud.com/user-13-877800258/strange-audio-on-freq-454080 While scanning my Ham Radio I came across this strange transmission on 454.080 in NYC. This frequency transmits randomly but frequently. *I don't really know what to make of this. *Is it an emergency station that people use only during national disasters? *Do they use the tones to make sure the station is functioning properly? *If anybody knows I'd appreciate some help. Thanks!

    DX Heat is A very good Website, as it shows a live feed of spots, showing band and mode. There are a few apps which carry out a similar function. On the iPad I use one called iDX. Kind regards, Phil

    google ham radio/amateur radio clubs in your area...you will likely find all the help you need there... you can also google the repeaters in your area, but that list will not tell which are the most active... local club members can do that.

    Hello All, I am a new member and my name is Hector Caroselli. I am a retired IT professional living in the Pacific Northwest, in the US. Recently I decided to address one of the items on my bucket list and get a Ham license. Trust me when I say I am very new to this and can barely spell Ham Radio. As usual I approach things kind of backwards and yesterday purchased a hand held unit. I am looking for training aids, classes etc in my area so I can prepare for the Technicians license. Any suggestions will be greatly appreciated. I have another question and I hope it's not inappropriate to ask in my introductory post. Until I have my license I would like to listen to or monitor some channels on my radio. This is really embarrassing :redface-new: but how do I know which frequencies might be most likely to have activity in my area? I guess I need a jumpstart or kick in the pants to get me going. Thanks in advance and please accept my apology if I have violated any forum protocol. Hector

    What do you mean by "not completely perforated"? Here is a picture of The Wireman #562 and #554.

    Pull it to pieces, and investigate! You might discover a tiny bit of grit or broken membrane which with your tec licence, should be able to fix. A bit like qualifying as a car mechanic and then giving your car to the dealer to investigate a rattle!

    Hi all, I've just joined the forum and am hoping to pick the brains of some of you wise folks. I have been dabbling with radios since I was about 8 and my parents bought me my first set of Motorola Walkie Talkies. This led to a natural progression into Ham Radio and acquiring many assorted radios and odds and ends to build all sorts of contraptions. I now mostly use my Ham for SAR as well as convoy trips and out of cell coverage coms. Living in NZ, naturally I have a number of Tait mobile and portable units as well as the old trusty Icom portable. So here goes... I have a flexible antenna that i use on the side of a backpack with the flexible part sticking out above my pack/shoulders. The flexibility allows me to walk under trees and other objects without worrying about catching the antenna on anything. It is primarily used for Search and Rescue, but I also use it on hiking trips and the like.

    Anybody know of an adhesive with good dielectric characteristics at 3.5-30 mhz? I need to secure an air-wound coil to a plastic strip, but I want to be sure the adhesive won't short the coil windings at these frequencies.

    Hello All, I've had the series of these h/t's for a while and yet I've never been able to figure out one thing...:confused-new: How in the devil do you receive 137 MHz thru 173.995 MHz on these radios? Also, does the "SCAN" feature with scanning thru the VHF receive? Can't find anything in the manual about it.

    Now is the time when the VE's should have put a HRO or DX Engineering catalog in the OP's hand and told him to go out and buy a power supply, a good radio, some coax and a resonant antenna... Too many people are in a big hurry to just get on the air, yet they don't really have anything to say. Find yourself an Elmer, not just Joe Blow, but someone that is truly knowledgeable, that can steer you in the right direction. Had a funny phone call this afternoon from a guy that has been a tech for 6 years. Said his tv wouldn't pick up the local station, wanted to know if they went off the air. I had to explain to him solar wind, how it worked and the fact that we have strong aurora and that it enhances the VHF while disrupting UHF -- sometimes.

    ...and the beeping continues. i guess the reset only put it off for just a bit. the internal voltage was fine, and it still retains memory after a main battery removal. perhaps it is just an artifact from age, or the previous owner may have dropped it, got it wet, or something. I just won't be able to use it for digital communications. perhaps in the future, it may work as a FOX radio. providing i turn the sound down ;) ~Travis

    I'm coming back to Amateur Radio after being off the air. I consider myself a new ham even though I've been licensed for a while. I tend to be interested in everything that humans can get into. I'm a guy who loves his wife and 5 daughters, technical things and writing. I'm a published poet with an IT degree and if it hadn't been for computers I'd be a history teacher. I just have a Baofeng HT but I'm trying to save up for a mobile HF/more all in wonder radio. I love the outdoors and am not afraid of manual labor.

    paulears replied to a thread My Microphone in Accessories
    Of course, but keep in mind that the agc is probably keeping the level from the mic fairly constant, so using a hotter mic could possibly not change very much. Try one and see - but only a condenser is likely to have much more in the way of output, and will of course also need a power supply/battery. Desk mics often have lower output than a hand mic as they are further from the lips.

    Hi Looking for a bit of advice. I have an Alinco DX SR9 tranceiver and I find to get a signal out on ssb I have to practically be touching the microphone with my mouth.The mic gain is set on a small pot on the circuit board and near the max. I am using the hand mic the set came with do you think I could use a more sensitive desk mounted mic ? Many thanks 73 Nev

    I have seen a key edge get caught under the case edge next to a button, but not on a radio. You might check for that.

    ok, this is very odd. my TH-28A seems to beep randomly. like if it was on key-lock, and a button randomly made contact. though it is not on lock, and the radio does not act as though a button is making contact. i checked all the buttons, to see if they functioned correctly, with the exception of the PTT, and everything seems to respond as it should. it is not the PTT button, and the on-air light does not light (fortunately, that would not be a good thing, to randomly TX). has anybody encountered this issue, or a similar one? ~Travis

    Experiment. I'd try for 40M first (it'll likely be ~half the length of an 80M antenna).

    Go back and read your General Class License Manual, it explains how a antenna works. A end fed wire will only have about 100 KC's of bandwidth and is not resonant on it's first harmonic. So you will not be able to use an end fed wire antenna for 80 / 75 meters and 40 meters - sorry. Regardless of what anyone else tells you, all an antenna tuner does is trick the transmitter into applying power into the line. SWR must be read at the load - antenna, not at the end of the feed line..

    Since it was just AM - the radios of the day were something along the lines of a S-38 or even a Hammerlund SP 10..... Even a old Knight Kit Spanmaster or Star Roamer would work. What you need is a transmit / receive relay - Dowkey company etc. I have one for sale - $50.00 if you need one. The relay basically takes the antenna from the receiver and connects it to the transmitter - when you engage transmit.

    well, it turned out to be a number of issues, none of which was a shorted external speaker jack. though the jack needed some cleaning. i also had to clean and bend down the contacts for the battery pack for better conduction, and the BNC antenna connector in the factory antenna is worn, so the antenna keeps popping out of lock, and making weak connection. so it was an easier fix than i thought. the antenna i will likely replace, though right now i have a piece of tape to keep it from unlocking. it presented symptoms of a short, but fortunately it was not. though the included NiCad battery pack needs replacement, as it no longer holds even a 10 minute charge. i have the AA battery pack for backup, but i prefer re-chargeable. ~Travis

    Hello. Iím heading to the States this weekend, and would like to know if there are any retail outlets which sell the programming cable for these radios ? Or alternatively, are there any Canadian stores which would sell this table? Any assistance with this would be much appreciated! Thank you, and enjoy your day.
