You could call some ham radio stores and ask about a radial kit for the UHV-4. google found a post mentioning the radial kit, so it may be available. If not, then you may just want to leave that antenna for mobile use, and buy a different base antenna from diamond or whatever. That radio...

You need to define the term 'swing'. because standard AM will have swing when 100% modulated compared to dead key. I think RMS power will be 1.5x more when 100% symmetrically modulated with sine wave audio, compared to dead key RMS. Perhaps 'swing' is when the RF carrier is purposely...

Amateur radios sold in the USA do not need FCC certification. Like they said earlier in the thread, a licensed amateur can use a toaster on the ham bands if it meets the technical standards of part 97. This is why those 10 meter radios do not have FCC certification tags. However CB radio is...

perhaps you could get a better understanding by looking at the propagation charts. ARRLWeb: QST Propagation Charts The space between the blue line and the green line are the frequencies that should work. Often 30 meter provides the longest opening between locations. But sometimes 40...

Where do you get this word "export" from? They are not called that, they are 10 meter radios. "export" implies something intended for another country. In this case, 10 meter ham radios are legal to sell in the USA. These are not CB radios. Some hams might think the manufacturer of...

This whole healthcare thing could just be the GOP making a mountain out of a mole hill. Here in california we have an option of workmans compensation insurance provided by the state. Its provided for businesses who might not be able to afford to buy that insurance from a private carrier...

Its just like the shamwow when they say "beware of imitators", when there arent actually any imitators.

If your running a class-C amp, you can power it right off the big capacitor(s) inside the supply, right after the bridge rectifier. its 18v at no load. But dont run any radio off that point.

CB radios use a microphone input. But your audio equipment outputs line-level audio. Line-level audio is generally too much to drive into a CB microphone input, so you need to attenuate it. Line signal to microphone input I cannot say if you really need that much attenuation. You would...

yea, a bunch of sillyness RIP = Really Important Pedophile But seriously, you gotta realize the guy did not have a normal childhood. He was abused by his father when very young.

i'll go with SR385 and say the antenna setup has more to do with TVI type troubles than anything to do with your radio equipment. Yes, an over-driven amplifier will have harmonics which cause TVI, but otherwise the common-mode currents from an unbalanced antenna without adequate counter-poise...

When the DX is hot I give a holler on AM 28.085 for CWMorse, because you know he is there listening.

Although reducing bandwidth used, and having the digital features are good things, the AMBE vocoder used in d-star is proprietary. Proprietary has no place in ham radio: its codes & cyphers.

somehow I get the feeling this could be similar to a Super Wack Pack. A diode and a wire and..

Digital television by itself is fine, what sucks is the heavy compression they use on hi-def signals on the cable tv. It makes fast-action scenes look all blocky and distorted colors. But the good side for analog TV being shut off is the 54 - 88MHz and 174 - 216MHz bands being free for the...

It says here 3.8kv gives 4.5kw-RMS / 10kw-PEP http://www.arrakis.es/~ulvinsl/eng/pos_mandos.pdf

Talking out of both sides of the mouth means to say different things to different people. With such discussions of technical nature, there's no need for such bias and half-truths. Perhaps you want a more basic explanation of radio propagation for the radio hobbyist. Groundwave, Skywave...

shame on you boys for having fun outside of ham radio :) CWMorse will call the radio police on you folks. LOL.

Highly depends on the type of television. For instance the Plasma variety of television are fantastic RFI generators. The screen has thousands of tiny wires carrying wide-bandwidth high-current signals. But if you have a different kind of television, you should describe how close your CB...
