    Is there a CTCSSish issue here? Maybe someone monkeyed with a programming preset on accident. I would be getting all over that problem if it were me & my station.

    Sounds like maybe a feedback related artifact. Check swr, maybe common mode pollution on the coax... are you under the antenna any appreciable percentage? Does it do that only with the Heil headset? Need to narrow down the possibilities here...

    What are you powering it with? it could be a power supply issue if you're driving it too hard...

    Also, check the squelches on all three radios. They should be set so that even a weak signal opens the receiver. Ben

    hello, I was wondering if anyone has had this problem with the ts 480hx.. I am using a Heil headset and I have it plugged in my radio and the headset is plugged into the headphone plug on the radio. My problem is when I TX there is a buzzing sound coming from the radio. It sounds like a cracked speaker. I bought this radio Brand new a year ago last August so of course it is out of warranty. It doesn't seem to affect the way the radio works, it just drives me nuts.:mad-new:Thanks osfp40

    Most likely water in the coaxial cable, it's not repairable. Change the coax and make sure the new one is properly sealed with self-amalgamating tape at the antenna end...

    This is about a VHF system used by a volunteer fire department. By day I'm a computer guy, so apologies in advance if I get any of the lingo wrong. Our station is in an island community, and about 9 miles away from county dispatch. We are not the town's main station. There is not a whole lot of topography, and sometimes the radios work just fine. Sometimes they don't. Each Sunday, dispatch conducts a radio check of all police, fire, and EMS units. This past Sunday, only the handheld received anything at all during the radio check. We have a base station with an antenna on the roof, a mobile in the fire truck which was parked outside the building at the time, a mobile in the utility truck which was off at the time, and that handheld.

    Hi Everyone, im very new to ham and looking to build my first antenna and trying to figure out what i need for tuning. Im thinking to get a NanoVNA as its $50 (so why not) and it looks like it gives all kinds of details like SWR, resistance, reactance, ect. My question is what else should i have for testing / tuning? I was looking an Antenna analyzers before the nano such as the MFJ 269C but i dont see what that would give me over the Nano other than a 2nd opinion. I was thinking an inline SWR meter MIGHT be nice to have around as i understand in higher power situations the SWR can go up if the antenna is too close to say a metal roof. Thoughts? feedback? something im clearly missing? Is this already covered somewhere that i missed? thanks tim

    Greetings fellow hams, I was wondering if anyone has used the Ulefone 3wt? It has some cool claims being a radio and a smart phone. Not to mention IP68 Waterproof, Shockproof, Dust proof. But i am really curious if it can hit 2m? I have ordered other Chinese radios in the past that claim they cant hit 2m and of course can. So i figure unless its blocked in the firmware it should be capable. Contacting Ulefone proved to be unhelpful. Additionally does any one know of any competitors to this radio phone? This is one of the first ones i have seen on the market in a while. Only other radio phone i know about is the Outfone Rangerfone S15 (and that's becoming out dated).

    Hello, I am from Bruxelles, Belgium. Well, I currently live in Belgium, but I am from Italy. I have had my license for a few years, but I have many hobbies, so I manage to do very little activity. Still, when I have some time, I like to learn something new. To me it is very important to understand deeply how radios work, down to the maths (I am a mathematician in my daily job). I much prefer being able to build a radio that transmits across the road understanding everything of how it works, then having a powerful expensive box that transmits from Europe to Australia, but that is just magic to me. Unfortunately many ham resources often skip the maths and just give qualitative explanations. They're good, but I like to get deeper. If someone has resources to suggest me, I'd be happy to read them. Thanks!

    This has been made WAY more complicated than needed given the parameters requested. Don't over think it. Get two 2M mobile radios, put one in the car with a vertical antenna, Larson is well regarded. Put a power supply and the second mobile in the house with a vertical mounted antenna on the top floor. Done. 6M is sunspot dependent.

    I had time to play around with this a little bit this evening and I was pleasantly surprised. I was able to access one of the local repeaters with good signal using this antenna and a Chinese 5 watt HT! I have the antenna on a 10' piece of PVC pipe sticking in a tripod mount on the ground.

    A heavy 2 m x 2 m floor-standing wooden showcase in the shack appeared to be suitable as a frame for a crystal radio loop antenna. As luck would have it, the lone 20 km distant 612 kHz, 200 kW AM broadcast station being in the end-on position by default, there would be no need to move the unit. The counter top would make it quite convenient to sit down and carry out the testing. The 5 turn loop was easily wound using about 42 m of ordinary hook-up wire. The shack is relatively quite small to get a photo of the actual unit. Here's a representation of the same. It works quite well with my series/parallel-tuned crystal radios.

    None of those frequencies are allocated to us - we would lose our license if we used them for amateur radio... you do mean MHz don't you?

    Absolutely! I'm a member of a railroad museum outside of San Diego, CA. At one time I was a train crew volunteer and fully rules qualified. I'm retired from that now, but I still listen to the local railroad frequencies at home. On an FTM-100DR... I also use the radio to listen to Marine VHF and local CalFire and USFS fire frequencies, all of which are outside the amateur bands. The radio will also receive Air Band AM. I listen to the towers at the local airport and the Marine Corps Air Station. To be able to do this, there is a setting that has to be made. When you receive the radio, look at page 140 of the manual to see how to expand the receive coverage. When the radio is programmed for those frequencies, if the PTT is pushed, all that shows up on the screen is the word "ERROR."

Iím looking for information on a few antenna typesówhat theyíre used for, where you buy them, that kind of thing. If youíre willing to help, do you mind taking this super quick survey? It doesnít ask for any personal info., and you wonít be added to any mailing lists, I swear. 1. Do you use any of the following antenna types? If so, what do you use them for?  Omnidirectional 450-490Hz Do you use ? Application(s):  Omnidirectional Collinear 806-960Hz Do you use ? Application(s):

    I have just joined this forum and I have a question for anyone who may know. I am receiving a Yaesu FTM100DR in the next couple days. I am also a scanner fan especially Railroad radio, as I am a retired railroader. All AAR frequencies are in the 160 to 161 Mhz range. Can I manually program these frequencies in this radio for receive only, of course. As I said I have not actually received the radio yet so I haven't been able to do anything. Just wondering if anyone could help me on this issue. Thank you in advance Rich

    SDRplay have announced a new member of their RSP family of SDR receivers The RSPdx is a replacement for the highly successful RSP2 and RSP2pro SDR receivers, which have been extensively redesigned to provide enhanced performance with additional and improved pre-selection filters, improved intermodulation performance, the addition of a user selectable DAB notch filter and more software selectable attenuation steps . The 14-bit RSPdx , when used in conjunction with SDRplayís own SDRuno software, introduces a special HDR (High Dynamic Range) mode for reception within selected bands below 2MHz. HDR mode delivers improved intermodulation performance and fewer spurious responses for those challenging bands. The RSP2 and RSP2pro design is over 3 years old now, and so the RSPdx has taken advantage of a lot of the learning from our work on the newer RSP1A and RSPduo designs as well as ongoing feedback from customers. The datasheet for the RSPdx can be found here:...
