be prepared:
Question, what is "basic HF and VHF capability "
Just for my own information, (not coming from a radio guy.)
Good question, those are just a couple abbreviations for parts of the radio spectrum commonly used by amateurs.
HF = "High Frequency". When people talk about "shortwave" communications, they are generally talking about the HF portion of the radio spectrum. There are a number of bands within the HF part of the spectrum. Some are better for daytime, others at night, due to the way the radiowaves use levels of our atmosphere to reflect them back to Earth. Worldwide communication is possible using HF communications. Local communication is also possible via groudwaves, direct from one antenna to another.
VHF = "Very High Frequency" is used for reliable, local point to point communications. With a repeater, a wide area can be covered. A repeater system takes in transmissions, and rebroadcasts them at a higher power. That allows someone with a low powered mobile transmitter to be heard at the repeater, which has a superior antenna and receiver, and then rebroadcast it across a wide area at high power so other mobile, (and base) units can receive it. Police and Fire utilize systems like this, either in the VHF, or UHF (Ultra High Frequency) band. If the repeater antenna is in a good, high location, great coverage is possible. If it sounds a little like how cellular systems work, there are similarities. Other users of VHF would be marine FM radios. TV signals are also in this range, as well as FM radio stations. Amateurs run their own repeater systems, which can be linked together for very reliable, and wide coverage capability. They are used daily for routine traffic, but can also form a backbone for emergency response as well. Many repeaters are configured with redundant systems, and backup power.
