Wed., Oct 6 - A backup loaner 88.1 Transmitter has been installed as the main transmitter is being repaired. 88.1 is currently at 100% power.
Thur., Sept 29, 3pm - The 88.1 signal is currently down. Andre went to the site to troubleshoot the signal being down, and in consultation with the Tower Engineer determined that the transmitter has failed. The transmitter was pulled from the site and will be repaired ASAP. We are working to get a temporary loaner on-site. This is the second time the Ft Bragg transmitter has failed this year and is indicitive of the defered maintanance that has happened over the years. The equipment and site enclosure are original equipment from when the site was setup. We are looking at a site overhaul.
Thur, Sept 18, 11:00am - UPDATE - Transmission line from transmitter to antenna needs replacement, which will nessitate another tower climb or bucket truck.
Thur, Sept 18, 11:00am
Tower Engineer is currently on-site and going up the tower to troubleshoot the antenna issue. This will nessitate powering down the 91.5 transmitter while diagnostic work is going on. The transmitter will be powered back up to it's current 10% of full power after the trouble-shooting work is done. Then a plan will be set to get whatever parts are needed and the schedule a date and time to replace them.
Sun Sept 14 - 91.5 Transmitter cycling on and off. Something is causing the transmitter to power cycle. Tower engineer will conduct site visit ASAP.
UPDATE & ONGOING - Tower Engineer went to the site and there is a fault with the antenna. The transmitter was placed in low power mode to prevent the power recycling, but it is only operating at 10% output. Next steps are to get up on the tower to troubleshoot the antenna itself, and see if it is the bullet burned out, or a break in the line. This will be done in the next week or so, ASAP
Resolved - Sat. Sept 13 - Jukebox not recording content - Troubleshooting on our end, may have to speak with vendor tech support Monday.
Resolved - Thur July 31 - Online Steam is down. Everything on the Philo studio side is working correctly. Checking with MCN and NPR support for cause.
Resolved - Mon July 28 -Ft. Bragg 88.1 Transmitter exciter down. Picking up alternate station. Going to transmitter site Tues., July 29 AM to troubleshoot and repair.
Resolved - Wed July 23 - The NPR Satallite feed went down for approximately 8 minutes from 8:34am to 8:42am.
Resolved - 91.5 Micro Dropouts - UPDATE 7/17/25 - STL amplifiers are being installed, the reciever portion was installed at Laughlin Peak and the transmitter STL amplifier is scheduled to be installed at the Cold Springs transmitter site. UPDATE - Installed, UPDATE - Receiver STL installed at Laughlin Peak - Last phase will be the realignment of the STL microwave dishes.
We are aware of the micro dropouts on the 91.5 signal. This is due to the STL (Studio Transmitter Link) microwave signal that goes out from the Cold Springs transmitter site and received about 40 miles away at the Laughlin Peak transmitter site. STL strength readings have been taken and are very low, and the digital signal is occasionally too weak for error correction to accommodate. it is most likely an alignment issue between the microwave dishes on Laughlin Peak and Cold Springs. It's also possible that it could be co-channel interference or local signal interference at Cold Springs or at Laughlin Peak that is affecting the microwave signal. This is not an issue in the broadcast studios. Thank you for your patience and understanding while we work on this with our Tower Engineer. Two crews with bucket trucks will most likely need to be dispatched to both tower sites simultaniosly to
