Can HF radios communicate with UHF or VHF radios?

Not Much . Not a whole lot other than use it for a paperweight. Best thing to do is sell it unless you can find a reason to keep it.
Whether its a handheld, a mobile in a car, or a base unit, they all work the same way. They work just like your cheap walkie-talkies from Wal-Mart that you played with as a ki…d, you key the radio and speak and the others hear you. As far as vhf or uhf, these are bands that the radios transmit on. The typical business/industrial/public safety bands are 800 mHz, VHF, and UHF. VHF stands for Very High Frequency and are from 30 to 300 mHz but typically for these radios it will be in the 136 to 170 mHz range. UHF stands for Ultra High Frequency and run from 450 to 470 mHz. And there are lots of areas in between that are used by amateur radio operators. VHF is good for long range on flat terrain. For example on the Interstate. Not so good for urban type areas with lots of buildings, concrete or steel. UHF is good for urban type areas where you may be in a building. Not as good for long range compared to VHF, but is better than VHF in urban settings as it can penetrate steel and concrete better. So it really depends on how you will use your radios as to which band you will want to consider. As a side note to this there are a few frequencies that the FCC has set aside for say business use but they are limited to certain handhelds with certain power requirements, these are GMRS (UHF) and MURS (VHF). You cannot use mobiles or bases on most of these. To be able to do this you must apply for and be granted a license from the FCC. IF in doubt on whether or not you need a license check out www.fcc.gov for info.
VHF is the radio range of 30 to 300 MHz. CB radio falls into HF (High Frequency), with all frequencies used being under 30 MHz. Frequencies under 30 MHz will hit the ionospher…e and bounce back to Earth - this is called skip or DX. Frequencies over 30 MHz typically penetrate through the ionosphere, causing a line-of-sight limitation.
very carefully, unless you know what you are doing.
history of vhf radio
Not really. The UHF operate on an entirely different frequency spectrum that the VHF. UHF ranges from 225-399.975 whereas the VHF ranges from 108-115.975/116-148.975/ or 30-89….975
Very High Frequency.
it rely depends where you are. UHF stands for ultra high frequency and vhf stands for very high frequency. vhf has ben around longer than UHF making them cheaper to use but UH…F means smaller antennas and better output. vhf is better in rural locations with expectations to be used in close proximity because buildings and natural barriers affect them. UHF can easily get through buildings and natural barriers but you pay lots more for them. but any to answer you question they do use both just ask your locals what they use.
Any antenna can receive anything, but not very well unless it's the correct length for the frequency you're trying to receive. Yes, this antenna will work well so you wil…l not need a special FM only antenna.
No, they cannot.
The Motorola Radius GP 300 was designed to be a business-class portable targeted at business, industry, school districts, and other non-public-safety users. The Motorola HT… 1000 portable was designed to be a public-safety grade portable, and as such is built much stronger than the GP 300. The HT 1000 also supports many more signaling formats than the GP 300 does.
The PRC77 radio operates on 30.000 to 75.95 MHz. If the Harris radio operates on any of the same frequencies (I know you said it's VHF, but VHF covers 30 to 300 MHz), then it …can.
There have been recent studies that show elderly people can not learn the technology of today like younger people can. This is true for some people, but not for others.
UHF radios are handheld radios. They are a great 2 way radio that are used by police, children, and hikers. They can be used by anyone needing to communicate via 2 way radio i…n the outdoors or indoors.
No. The acronyms stand for different, non-overlapping frequency ranges. Since the #1 immutable requirement for radios to be able to talk to each other is that they be on t…he same frequency, and since HF, UHF, and VHF radios are by definition on different frequencies, that match would be harder to operate successfully than a mixed marriage.
