GMRS Simplex

There are specific calling frequencies for GMRS (General Mobile Radio Service) channels. The primary GMRS calling frequency is 462.550 MHz, which corresponds to GMRS channel 15. This is widely recognized as the main calling channel where users initiate contact before moving to another channel for conversation to avoid congestion.

Here's a brief overview of some common GMRS channels:

• Channel 15 (462.550 MHz) - Main calling frequency.

• Channel 1 (462.5625 MHz) - Often used for calling as well but less common than channel 15.

Remember, while these are calling frequencies, etiquette dictates that after making contact, users should switch to another channel for extended conversations to keep the calling frequency clear for others.
