    Thanks Dan. Great reading material there. I'd seriously love to experiment with the ladder line, but just can't afford the balanced tuner:-(

    Hello Dougal, WOW! You're absolutely right on the Balanced Output on the Antenna Tuner Units as they're Expensive. I did find an interesting article on the Ladder Line on the KV5R.com website: http://kv5r.com/ham-radio/ladder-line/ I thought you might want to read the information about using the 450 Ohm Impedance Ladder Line, the Do's & Don'ts while performing the install and actual using this transmission line.

    I used a wire antenna for AM in my loft with an home made tuner on it. Had it for years and heard world wide stations. It is still there and due to be resurrected so I can tell if my FT- 897 is sending. I also use a wire dipole with tuner for the FT-897.

    paulears replied to a thread AM antenna in Antennas
    The ones normally used for Am reception tend to be very long wires, or simple loops of single core cable - 6-8" diameter, and wrap perhaps 20 turns of single core around it. You do need to turn them, but they work surprisingly well.

    Any wire can be used for receiving and wire is cheaper than a loop and not so directional! Depends on your budget and and cost versus use! With wire as much as you can as high as you can is good! :encouragement:

    Thank you for the quick response: I really appreciate the help I just didn't want to see how fast the smoke detectors would react. The cost of the two finals are a set back once, didn't really want to keep buying them over again. I'm not that smart on solid state electronics. I figure it would be a good winter time project to tackle this. With help from people like you it will make it a lot easier and a great learning tool. So thank you! N0SIB.

    As Pete said very true. We seem to get quite a few members who never research the question they are asking and expect others to run round after them. Helping people I don't mind but wiping their backsides as well gets a bit wearing. The other and off topic slightly thing is, where can I get a keyboard that can spell?

    Simple answer - you can only talk to people if you have the correct license. You can only use a radio without a license on a very small number of specific frequencies, but the radio needs to be a certain type - which your Baofeng is not. Power and detachable aerials are the problem - license free = low power and an integral aerial. If you try to talk to the local zoo on their channel they pay a license for, firstly they probably wouldn't hear you because they almost universally have a tone system in operation, so unless you set your radio to transmit their tone, they don't hear you. If they did hear you, they'd probably ignore you and if you annoyed them they're report you to OFCOM, who might or might not do something about it. Fines can be high and they confiscate equipment. You do NOT learn this on the ham test because it only deals with amateur issues. Remember that there are loads of different licensed types of radio - each one totally separate. If you want a marine license, there is a test. If you...

    I think you've got totally the wrong idea about ham radio! You also really just need to go to the right place to find out everything - the RSGB website. Clearly not every ham likes the RSGB, which is perfectly fine - but they license the repeaters, do the negotiation with OFCOM on licenses, and most of the radio clubs are affiliated to them, so pretty much every single thing you need to get licensed is there. One thing is important though - if you are worried about money, ham radio is 100% NOT the hobby for you. even with radios being dirt cheap, and pocket money prices nowadays, you will find that being a hand-held single radio owner very, very limiting, and to be honest, a bit boring. If the only people you can reach are those on a repeater, then in many parts of the UK, you will be pretty lonely. Activity is low - so many hams then progress to one of the other elements of the hobby. The cost of your training course and license are tiny compared to better cable, better radios (being honest, the Baofengs...

    Hey all, I am brand new to ham radio--never used one but became interested. I started studying for the Technician test about a month ago and took it yesterday and passed so I guess I am legal. But I don't know much, so I will probably lurk around in here for a while to glean information and to keep myself from looking too much like a clueless idiot to the members here. Looking to buy my first radio. Went down to HRO Friday and was mesmerized. I am leaning towards a Kenwood TM-V71A but if I can pull a few more dollars together, I would love to get the Yaesu FTM-400XDR. Anyway, just saying howdy.

    Hello I'm looking into getting a license soon and I haven't read around wich I will soon but as there's not any prices as of 2017 uk well that I can find however I haven't looked much so maybe I missed the pricing but I would like to know what the price would be for the cheapest I can get to talk on repeaters and all channels the uv5r can cover like mine covers 136-174 vhf and 400-520 uhf so a license what I could talk on most of them covered channels. My area I can't seem to find a radio club I don't know if I have to go to one to get a license I think I read I do but I need to read more. On things I've read people say buy books or stuff like that but is that needed or can I just remember whatever I need or look online as I don't really buy books lol I tend to go online a lot.

    WA9WVX replied to a thread Ladder Line Question in Antennas
    Hello Dougal, I'm not exactly sure what type of Ladder Line you intend to use, 600 Ohms or 450 Ohms? Before the use of 50 Ohm Coaxial Cable, everyone used 600 Ohm Ladder Line and in those days 600 Ohm Ladder Line was bare wire which posed a problem to anyone walking up to your antenna Ladder Line and touching it. They would receive RF burns when they grabbed the Ladder Lines while you were transmitting. So I would make sure that the 600 Ohm Ladder Line was up in the air at least 10' so no one would receive any RF Burns. Ladder Line has some advantages to long runs by having a Low VSWR & RF Losses for the entire length. If it Rains or Snows, the moisture and/or Snow or Ice will change the 600 Ohm Impedance. You can run the Ladder Line to your house and installing an entry panel with Feed Though Insulators spaced exactly the width of the Ladder Line like the MFJ-4600: http://www.mfjenterprises.com/Product.php?productid=MFJ-4600 And a Lightning Protector AS-309H mounted right before the 600 Ohm Ladder...

    Hello everyone today I want to ask a few questions on about operating frequencies. I am not a proper ham licensed user I only use my ham radio for listening and well I am going to get a license very soon because I really want to start talking to others but it's funny picking up local radios and repeaters. Ok so my questions is - when or if you have a license and I know there are more than one license and have not read the difference between any of them but the thing I want to know is if you have a license can you talk on any channel at all like I have the uv5r and say I went to like frequency 445.500 or any single one I can type in and say if there was a buisiness idk like say a supermarket a zoo a security for a club anything like that is it illegal to talk or transmit on there channel? As you have a license i pursue you would be allowed to talk to them but it would be disrupting them but is it illegal to if you have a license because it's a channel what's not private right ? I think you would learn...

    Hello Milt, I remember when Kenwood first brought those transceivers out on Amateur Radio Market in 1987, they were an ideal transceiver for in an automobile or for use as a Fixed Base Station in your home. Years later I heard a story where some old timer I'm guessing in his eighties thought he could make his TS-140S more sensitive by tightening all the cores in their I.F. transformer cans which he did but by doing this he turned a perfectly good transceiver into a piece of Junk. People like him need to keep their hands out of their radio equipment. You're a brave individual tackling a Basket case transceiver like the one you have. I went out to mods. DK and downloaded the Service Manual for the TS-140S & TS-680S transceivers and scrolled down to Page 116 for the RF Power Amplifier Board. I looked at the transistors that would need Insulators and Thermal Grease applied to help dissipate the heat. The following transistors Q1 through Q7 Plus CN3 will require Insulators & Thermal Grease also known as...

    So after doing some diggin on the radio if I unplug the mic the drifting down stops. If I plug it back in - it starts drifting down again. The mic came with the radio and it's a Icom HM-12 Microphone. It has a switch on the back of it that says: UP/DN and then under that silk screen OFF and ON - right now its switched off. So something in the mix is making the radio tune down or channel change down when its plugged in. Any guesses?

    Dougal started a thread Ladder Line Question in Antennas
    I'm thinking about experimenting with ladder line to my dipole instead of the RG-213 coax. I believe 'the norm' is often to run the ladder line for a short run to the tuner, then coax to the shack? Is there any reason why I shouldn't run the ladder line right into the shack, with just a short patch lead from the tuner to the radio? It's a fairly long run from the antenna feed point to the shack - probably around 150ft

    First off thank you for the help: I bought ts140s as a basket case a while back the person had the final board taken out and some of the transistor were missing: What I need help with is, does anyone know which transistor have to have the mica insulators for mounting them and which ones don't. I know the two final do not need them but not sure about the others. Books do not show that part and I have no way of knowing! Thanks again for the help.

    You DID get the manual with the radio, right? If not, as Paulears said, you can download a copy and save it (or print it). Google something like "TS-820S manual". The manual is where you should look FIRST, before asking questions on an internet forum.

    paulears replied to a thread SWR meter in Antennas
    It's a return loss bridge - they were quite popular for a time - many people don't like the fact that you have to stick power into a poor matched aerial system to get the news the VSWR is rotten, so these things present a 50Ohm load to the transmitter - and then only a small amount goes up the spout, and the LED goes out if nothing is returning to excite it. Pretty neat really. You can spend a fortune on a proper Bird Thruline and the plug in expensive bits, and get a truly accurate result. You can but the kind of meters many of us have and get a rough idea of how good the aerial is matched - but seeing the LED light simply reveals power is coming back, and if it doesn;t light, it's not. I'd be happy with that, and not really worry if my VSWR was 1.1, 1.2, or maybe even 2.1? Others want an absolute readout - which requires a VSWR meter. This gadget just does the job simply.

    I'm really confused. You set it to usb (or lsb depending on band), and turn the volume up and noise comes out of the speaker? You don't really have to enable anything - the CW setting on receive just is a very narrow filter setting, that will let you hear voices, but usb and lsb are the usual settings. I don't quite understand how you haven't discovered this - I suppose something could be wrong, but the manual is available on line, despite the age of the radio. This explains the operation quite well, but does assume you are already a ham operator and have the necessary background to follow what's going on. Is your one dead, and this is what you are worried about.
