Studio and Transmitter Maintenance
October 2013 - August 2015

Signal Wiz was called in to improve maintenance at KPRI.


  • replaced their aging automation system with a new Wide Orbit for Radio system.
  • rebuilt the air chain, making it all digital from the mic processor through to the transmitter on Mt. Soledad. Since they had high quality audio mixers and router, we were able to greatly improve audio quality without buying much new equipment.
  • tuned their microphone and on-air audio processors.
  • removed transmitters and associated equipment and oversaw the antenna removal from a no longer needed auxiliary transmitter site near San Marcos.
  • improved their IP infrastructure by replacing the firewall and lower rate switches.
  • set-up a small performance studio for visiting musicians.

The station sold in 2015 to the Educational Media Foundation, a satellite repeater service that has no studio presence in San Diego. The callsign was swapped with a radio station in Julian, California.

We loved working with KPRI independent owners Jonathan Schwartz and Robert Hughes and their staff.

>Mountain Country 107.9 LPFM

KRLY Alpine

No project too small
July 2014

KRLY "Mountain Country 107.9" serves Alpine, California from a low power FM transmitter 25 air miles east of San Diego.

Owner-operator Chris Torrick needed to move his studio down the street to new digs. Signal Wiz identified all of the equipment and cables. Then Chris played a recorded day's programming from his transmitter site while we and some volunteers moved everything to his new studio location. We rewired everything, moved antennas, and retired some of the inoperative gear--all in a day. We returned later to spiff everything up for permanence. The move fit his budget and no one got hurt.
