FCC Reminding LPTV Stations to Abandon the 600 MHz Band

FCC New 2020 Logo

The FCC yesterday issued a Public Notice reminder for low power television stations to cease operations on the “duplex gap” spectrum by the end of July 13, 2020. Some LPTVs were allowed to continue operating temporarily on TV channels 38 where a guard band exists between telecom channel A and old TV channel 37, or on TV channels 44, 45, or 46, where there’s a duplex gap between telecom uplink and downlink channels.

In the San Diego region, Entravision’s KTCD-LP on Mt. Woodson operated for a short time on channel 46 with analog service. They’ve since signed off.

In Los Angeles, KTAV-LD operates on channel 46 and will have to shut down or share a channel since they have no pending application for a new home channel. [Edit 6/23/2020 – The FCC granted KTAV-LD a Construction Permit for a displacement allocation on channel 21 from a Beverly Hills tower site. Channel 21 is adjacent to land mobile T-band channel 20, and had been off-limits to DTV in Los Angeles. ]

Bob Orban Presents: “Maintaining Audio Quality in the Broadcast Facility”

Achieving excellent on-air and on-line quality audio is more important than ever because of the intensely competitive nature of available media. “Good enough” no longer works. Persuading audiences to listen and then return requires attention to quality at every stage of the production process, from program sources to audio processing. This presentation will help attendees achieve quality on-air and on-line audio broadcasting and netcasting goals.

Join Chapter 36 at either of two dates and times:

  • June 9th, Tuesday, 7:00 PM PDT, with Chapter 47 Los Angeles
  • June 24, Wednesday, 12:00 noon PDT, with Chapter 9 Phoenix

Send a request for either meeting to mailto:RSVP@SBE36.ORG. You will receive an e-mail two business days prior to the event with a GoToMeeting password. The presentation is open to members and interested guests.

You are eligible to receive the usual 0.5 SBE certification points for your attendance.

KFSD (AM) 1450 Back on the Air

KFSD Escondido returned to the air May 20, 2020 with its adult standards music format, just under a year after going silent in June 2019. The station, owned by the Astor Group, has been looking for a buyer to take over the station since Art Astor passed away in 2016.

KDTF-LD to Move to Soledad

The FCC on May 5, 2020 granted Entravision’s application to move Spanish language KDTF-LD from Mt. San Miguel to Mt. Soledad. Since last year’s repack, the station has operated on UHF channel 16, which is co-channel with T-band first responder fire and police in the Los Angeles metro area. The new antenna pattern will provide a deep null in the direction of Los Angeles and Orange Counties while transmitting a 15 kW ERP signal southeast toward San Diego, National City, Chula Vista, and Tijuana. Entravision operates Univision affiliate KBNT-CD channel 24 from the KGTV site on Mt. Soledad now.
