What is the frequency of 30m APRS?

Excuse me, could you please clarify what you mean by "30m APRS"? It seems like there might be a misunderstanding or a typo in your question. However, if you're referring to the frequency of a specific type of communication or transmission, such as APRS (I assume you meant APRS, which stands for Automatic Packet Reporting System, a type of communication protocol used in amateur radio), and you're asking about a specific frequency range or channel designated as "30m," then it's important to note that APRS itself doesn't have a specific frequency range associated with it. Instead, the frequency range used for APRS communication would depend on the specific regulations and allocations in the country or region where the communication is taking place. In general, amateur radio frequencies are allocated by the International Telecommunication Union (ITU) and regulated by national authorities, such as the Federal Communications Commission (FCC) in the United States. If "30m" refers to a specific frequency band or channel, it's likely that you're referring to a portion of the HF (High Frequency) spectrum, which is often used for long-distance communication by amateur radio operators. The "30m" designation typically refers to the frequency range around 10 MHz, which is a popular band for amateur radio communication due to its ability to propagate over long distances using skywave propagation. However, without more context, it's difficult to give a definitive answer to your question. If you're looking for specific information about the frequency range or channel designated as "30m" for APRS or any other type of communication, I recommend consulting the regulations and allocations for your specific country or region.
