Information About the Repeater

The K5VPW 441.625 mHz repeater is a three mode digital repeater running D-Star, DMR and C4FM (YSF, FCS). It is open to all hams and is located in northeast San Antonio, inside Loop 410. Feel free to use the repeater locally, link to a reflector, talk group or another repeater. If you do link somewhere, please unlink when you are finished. The transmitter and receiver are both Yaesu FT-7800's, cabled to a six cavity Celwave duplexer then cabled to the antenna. The antenna is a 11.5db gain, monoband vertical, up 25 feet at the base, fed with 1/2 inch hardline. The transmitter runs 5 watts and drives a Mirage amplifier. The amplifier is cooled by an external fan. After duplexer and feedline losses, 30 watts is delivered to the antenna. The repeater controller is a Raspberry Pi V3 with 1 gb of RAM and a 32gb SD card. It is cabled to a STM_32 MMDVM which is cabled to both FT-7800's. The Raspberry Pi image is Pi-Star configured as a repeater. Modes enabled are D-Star, DMR and C4FM. Internet speeds are 600mb download and 35mb upload.

The repeater works on a first come first serve basis between the 3 digital modes. If someone is on a mode, and users wish to use a different mode, they will have to wait 15 seconds until the transmission in that mode is finished. After 15 seconds, simply key up on the mode you wish to use and the repeater will switch to that mode automatically.
