ROCKY MOUNTAIN VHF SOCIETY

Repeaters transmit 100 Hz sub-audio tones but usually can be accessed via carrier squelch to facilitate use by all visitors and especially in times of emergencies when any additional technical restrictions might be a burden. A primary mission of the RMVHFS is to provide reliable and effective repeater coverage for Boulder County, and particularly for Boulder County Amateur Radio Emergency Services (BCARES). As such, the club operates in the public interest, but all repeaters are open to all licensed amateurs, local and transient to enjoy for routine use normally. Repeater and club call: WØIA.

Dues are currently waived for all new and current members. Please contact the officers below for more information.
