Information About the Repeater

The K5VPW 441.625 mHz repeater is a dual mode digital repeater running D-Star 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 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 KLM amplifier. The amplifier is cooled by an external fan. After duplexer and feedline losses, 33 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 Micro-Node Teensy MMDVM modem which is cabled to both FT-7800's. The Raspberry Pi image is Pi-Star configured as a repeater. Modes enabled are D-Star and C4FM. Internet speeds are 600mb download and 35mb upload.

The repeater works on a first come first serve basis between the 2 digital modes. If someone is on D-Star, C4FM users will have to wait and vice versa. When transmission in a mode is finished, wait 15 seconds and simply key up on D-Star or C4FM and the repeater will switch modes automatically.
