What are 70cm frequencies?
The 70-centimeter or 440 MHz band is a portion of the UHF radio spectrum internationally allocated to amateur radio and amateur satellite use. The ITU amateur radio allocation is from 430 to 440 MHz; however, some countries, such as the United States, allocate hams 420 to 450 MHz.
What are the FCC rules regarding the use of a phonetic alphabet for station identification in the Amateur Radio Service?
What are the FCC rules regarding the use of a phonetic alphabet for station identification in the Amateur Radio Service? Using a phonetic alphabet (also called a “spelling alphabet”) such as the NATO Phonetic Alphabet is encouraged by the FCC rules but not absolutely required.
What frequencies can a technician talk on?
Technician Class Frequency Privileges in Ham Radio
| Band | Frequencies (In MHz) | Modes You Can Use |
|---|---|---|
| 80 meters | 3.525 – 3.600 | CW |
| 40 meters | 7.025 – 7.125 | CW |
| 15 meters | 21.025 – 21 |
What are the restrictions in terms of geography?
Geographical restrictions exist for various frequencies in terms of usage in the United States of America as stipulated in 47 CFR 97.303. What are the restrictions, if any remain, in terms of geography where you cannot use all or part of the 70cm band?
Are there any restrictions on running a 70cm repeater?
The restrictions AFAIK are only mutual agreements with local ham operators and clubs (particularly clubs running 70cm repeaters), and have not been formalized as part of the FCC regulations. Here’s an article here for more info: http://www.arrl.org/news/new-70-cm-coordination-agreement-reached-for-new-england
Why is 420 MHz not included in Canada’s band plan?
Canada does not include 420-430 MHz in their band plan for 70cm, so the restriction is in place to prevent interference to Canadian amateurs. Actually, this is to prevent interference to non-amateur fixed and mobile comms; the treaty/arrangement text is available with a simple search.
