The regulations for an amateur radio repeater are fairly minimal. To answer your specific questions: "Does one need a particular license?" Your license must permit transmissions on the repeater output frequency. That is, general or higher for 10m, technician or higher for higher frequency bands. There is no special repeater license. (There used to be.) ...

You can find the code in packjt77.f90. Callsign encoding (for "standard" callsigns that don't require hashing) is in function pack28. A quick summary: Adjust a few strange prefixes that don't follow the usual arrangement of letters and numbers. Swaziland 3DA0* will be encoded as if it was 3D0* instead, and Guinea 3XA1A will be encoded as if it was ...

WA9ZZZ's answer missed the issue of control of the repeater. The repeater must be under control of one or more control operators, or under automatic control, at all times when the repeater is on. There are three types of control: Primary control, where a control operator is physically near the equipment and monitoring the repeater, ready to intervene as ...

The grace period is two years. You can renew your license within the grace period, but after that, the call sign will be available for reassignment. If you were to take and pass an exam after the grace period, you would be assigned a new call sign. However, if at that time, your old call sign is still available, you would be able to apply for it as a vanity ...

No — as of 2020 you're not obligated to change your callsign if you move within the US. Even if you have an Alaska/Hawaii/Guam "restricted" callsign, you can keep it if you leave. All you need to do is notify the FCC of your new mailing address via ULS. However, if you want to change your callsign when you move, you can. You can request the next available ...

Better double check. There's no requirement to identify at the beginning of a communication (though it's common practice, and was required at one time), only every ten minutes and at the end of the communication. The "every ten minutes" is often handled (say, on 2 meter or 440 band repeaters, which is where Technician licensees most commonly use voice ...

According to the FCC's Amateur Call Sign Systems page, Technician and General class operators are in the same group for call signs, so your call sign has a prefix of K, N, or W with a three-letter suffix, or a KL, NL, WL, NP, WP, KH, NH, or WH prefix with a two-letter suffix. Because you've upgraded your license but are in the same call sign group, you're ...

For United States Amateur Radio Call Signs I use this. Regex TheCallSignRegex = new Regex(@"^(A[A-L]|K[A-Z]|N[A-Z]|W[A-Z]|K|N|W){1}\d{1}[A-Z]{1,3}", RegexOptions.Compiled | RegexOptions.IgnoreCase); String Call = "w6am"; // Trailing spaces in the string 'Call' will return a failed match Match TheMatch = TheCallSignRegex.Match(Call); Boolean ...

I don't know any radio firmware that would support blocking a specific ID. It would be easy to implement in MMDMHost. Call Alert is a ringer function. If a radio receives a call alert signal then it rings and sends back an answer to the caller and the caller radio shows a message about the successful delivery.
