TWiRT 522 - Hawai'i IP Radio Link & Backup FM Transmitter

TWiRT co-host, Kirk Harnack, is part-owner of KHKU-FM in Lihu’e, Hawai’i.  It’s been 2 ½ years since the station, called “Star94.3”, went on the air under the new name, so some improvements and repairs have been needed. The key projects were: Installing an IP-radio link from studio to the transmitter on Mt. Kahili; installing a backup transmitter and antenna; and, wiring remote AC power switching for the main and backup transmitters and other gear at the transmitter. Kirk shares photos and video of the dramatic trips to Mt. Kahili and helicopter “rescue” necessitated by worsening weather.

TWiRT 521 - Hybrid Single Frequency Network with Hal Kneller

A Single Frequency Network (SFN) can help a broadcaster achieve coverage over a much wider area than with a single transmitter - and, provide continuous, hands-free coverage for listeners as they move about the trade area. FM on-channel boosters are another form of SFN.  Hal Kneller has designed and implemented numerous SFNs to give broadcasters better coverage for their listeners, and joins us to describe a recent “hybrid” SFN in Southwest Florida.

TWiRT 518 - C-Band Filters - IN or OUT? with Mark Johnson

The C-band repack – and subsequent relocation of all C-band users in the Mid-band frequency to 4.0-4.2 Mhz – means broadcasters with C-band satellite antennas need to act now. You may plan to self-install the filter needed to protect your satellite reception from new 5G signals. But, are you sure a filter is all that is needed? And, do you feel comfortable that your documentation will be adequate to share with the FCC when ATT or Verizon begin to interfere with your program reception? Mark Johnson with Linkup Communications describes the problem that broadcasters face, and explains the options available, whether you’re “opt-in” or “opt-out” of an FCC program.
