    Thanks guys. I'm only using about 12' of cable but it still sounds like I should go with something else.

    Hi I keep hearing a digi mode here in the UK i don't recognise on 14.080 and just wondered if someone can tell me what is it?

    From a voltage and dielectric standpoint, that coax is rated for 900Vrms. Assuming the worst case scenario of a complete mismatch providing an infinite SWR, the maximum the RF voltage applied to the coax should be half that value, or 450Vrms. This will ensure that under total signal reflection (standing wave sees 2x the voltage you put in), the voltage of the standing wave never exceeds the operating voltage of the coax. That should come out to about 4,050watts. Obviously, the coax is not going to handle that for heat dissipation reasons, but high SWR and arcing isn’t going to be the coax killer. The loss of this cable at 2m googles to around 14dB per 100’. This means if you put 65w through 100 feet of this cable, you would have about 2.5w make it to the other end in a perfectly matched system. The other 62.5w goes toward heating the coax. With that much loss, you wouldn’t even get a decent swr reading at the input end as the reflected wave encounters the same loss on the return trip. Summary: That...

    KD9KVS replied to a thread Hello everyone. in Introduce yourself
    Welcome to the hobby! These are some great questions you have, and the answer to them is, it all depends. Probably not what you wanted to hear, but there are many variables that play into being able to hit the repeater. One of the biggest is the antenna. Height, feedline, resonant frequencies, line of site and things of that sort. That applies to the repeater as well as your radio. I have easily hit a repeater with an 8 watt ht from greater than 10 miles away, but I had a magnamount antenna on top of my vehicle, creating an excellent ground plane. The nagoya ut-72 is a great antenna that handles 80+- watts, and comes with an adapter for ht's. A 25 watt mobile unit (qyt 8900d is what I have) got me into the repeater 20+ miles out. Again this will depend on antenna line of site and other things I mentioned earlier. Also check out the qyt 980+, that's 75 watts and does an amazing job. I use both of these models mobile and do not have problems. 8 watts is what I started with and had no problems, but it...

    Sounds like you have RF on your outer braid of your coax, If you put a 1:1 current choke balun near to your g5rv it should solve it. It did for me. There is loads of info online on building one but I bought one of these https://www.m0cvoantennas.com/apps/webstore/products/show/2628660

    Thanks for all the advice guys tbh I didn't know it was usual on 40 although I also have it on 30 & 20 as well but the attenuator does work. I have an ft450d as well so it's nice to know it isn't my setup and we're all in the same boat. Here's to my lucky day :-)

    Hello! Hey everyone, I'm new to the hobby and currently studying for my technician and general exam. I do have a few questions that I hope you all can help me with. I live out in the boonies surrounded by rolling hills and very tall pine trees. I did a search for repeaters in my area and the closest one is 10 miles away from where I live. I know you guys always recommend going to my local area Ham Radio Club but its over and 1 1/2 hour drive from where I live. From what I have read it would seem that the only way for me to be able to transmit and receive would be with a HF base station? So my questions are: 1. Is that the only way? 2. And if so how do I go about doing that, equipment needed etc... PS. I programmed a Baofeng FH-FH8P using chirp and bought a named brand Nagoya antenna and I get nothing at all. I hope you all can help me as I'm loving this hobby more and more everyday.

    Problem with Monitor tone on FT-1000 Monitor tone is constantlly on the radio. The level can be adjusted to zero by turning the monitor control fully anticlockvise. I can not turn the tone off using the MONI button. Is this a correct function?? Reading the manual: The monitor control adjusts the audio volume of CW sidetone and transmit RF monitor during transmission, when activated by the gray button with the same name. MONI gray button. Enables the transmit (RF) monitor in all modes (except CW, in which the onitor function is always on to produce the sidetone. 73 de SM3EQF Christer

    Hi, Not sure whether you've looked at WSPR? It can produce results like this: https://images.app.goo.gl/x261qET8BCmf4ym47 In order to see both ends of the transmission, you'd have to use something like a WSPRlite, which is a cheap plug and play device. Other transmitters are available, but my experience is that these are easy to use. Because they transmit a small signal, I believe that most countries would require that you have a licence. Hope that gives some food for thought.

    Not a problem at all. We all start not knowing, that's the beauty of places like this, we can learn. For chirp, go to the left side of the screen and click settings right under memories. About 2/3s down the first page (basic settings) you will see display mode (A) and display mode (B). Click the dropdowns and you will be able to select it from there. When you upload to your radio it will then appear in that format. Remember to save the image with the settings you want so that it will do that anytime you re-upped the image. If you create a new image with different memories, you will need to make sure these are set the way you desire. Sent from my SM-S767VL using Tapatalk

    Hello, Please let me start by saying that I know very little about radio. I've watched my boyfriend over the last several years here and there and worked some contacts with him but he is the HAM in our relationship. With that said, I was curious if there is a way of tracking / mapping radio waves. In short, he communicates with his father a few states away. I would like to generate a map showing the path of their radio waves on any given day when they communicate. Is something like that even possible ? Any insight into this would be greatly appreciated. I've tried searching online but I have concluded asking in a forum such as this would give me the clearest answers. I appreciate your time and look forward to your reply. Thank you !

    It is the "channel" names that can only be edited via software. If you want just a plain v.f.o. display where you can put in a frequency and use that frequency then your option is the orange vfo/mr button in the top left corner right below the screen. To get the frequency for the memory you are on press menu, press 21 or 22, press menu to enter options, press 1(for name on display) 2 (to select frequency display) 3 (for memory number)》you want to select 2 for this《, then press menu again to save. Press exit to return to the homescreen and the frequency for that memory will be displayed, instead of name. Using this method you can have the name as needed and still view the frequency. Your "channel" is always displayed on the right side of your screen in small numbers. The only reason I see to use "channel" is if you have someone who is not a ham, or much younger and that's all they need to know is go to this number. Do remember there is still additional information as far as ctcss tones and such that...

    To kd9kvs. I know about menu numbers 21 and 22. The manual that I have, the one that I d/l and the link that you sent me all say that #21 and 22 can only be done via a program software like Chirp. I have the prog cable, the driver for the cable is installed. I have the (A) display programmed except I can't get the frequency to display unless I type the frequency into the name column. This ht is the most complicated ht to program ether via direct entry on the ht's keyboard or via PC programming that I have ever owned .

    There is an option for it in chirp, I can't remember where, but to do it from the ht press menu, press 22 for b (21 for a) press menu, select the display you'd like on the radio, press menu again and you should be golden. Here is a link to all the menu options in your uv-5r https://www.universal-radio.com/catalog/ht/0205menu.html Let me know how that works for you. Sent from my SM-S767VL using Tapatalk

    I have the USB programming cable. I can upload the ht's memory and write to the ht's memory ok. I know how to setup the (A) display. I know all the info that was in the ht's memory. When I programmed a repeater into the ht via the ht's onboard keyboard. The repeater setup ok and responds ok. But the display shows in display (A) "CH-001" and not the frequency and no memory ch number to the right of the display. The only problem that I have in programming from Chirp is getting the display to look like the setup bellow. Disregard the uv-5r_v1.0.pdf file. I uploaded the wrong file the 1st time and I don't know how to del files in the file monument . In the jpg picture that I scanned from the ht manual. Where it shows the 145.125 in the lower display was FRS1 and the FRS frequency was programmed into that memory slot. I did look at the ht's setup via Chirp but I never saved it.The way the setup was, memory ch 1 to about 25 was filled with repeater and simplex frequencies on the upper display. in Chirp after...
