Channel 8 applied in late November to increase their power output from 19.8 kW to 87.4 kW ERP. KFMB Stations RF Supervisor Rick Bosscher says they can implement that power level with existing equipment. The station still uses an RCA omni-directional transmission antenna built in 1972 that handled 50 kW transmitter power. Their Harris iCD 30 transmitter, capable of 10.5 kW, has been loafing along at 2.4 kW. There’s an older Harris that can also handle the new power level, and that will continue as a backup unit.
VHF TV stations have had a hard time competing with UHF stations since the digital transition in 2009 because home viewers are trying to use indoor antennas with small apertures designed for UHF reception only. Signal penetration through metal-reinforced stucco causes a loss that used to create a poor viewer experience for rabbit ear antenna viewers, but those viewers who put up with static-filled NTSC video found themselves unable to get a usable ATSC picture at all.
The FCC opened a window this fall for all TV stations to upgrade their signals within the existing rules limiting interference. A number of UHF and VHF stations are taking advantage of this opportunity to boost their power.
The Board of Directors of the Society of Broadcast Engineers, the association for broadcast and multimedia technology professionals, during its National Meeting held in Denver Oct. 25-26, adopted a new member benefit that will be available beginning January 1, 2018, called SBE MemberPlus.

Ground is something you stand on, but in an electrical sense, the meaning is much less clear. When it comes to broadcasters and ground, things get really confused.
We drive rods into the earth, but why? Let’s take a look at whether any of this makes sense, and what theory tells us about “ground”, and if it exists in any sensible way at all. We’ll talk about DC grounds, RF grounds, and even about gravity.
Join us Wednesday, September 20th, 2017 at noon at iHeartMedia, 9660 Granite Ridge Drive, San Diego. Chapter 36 will provide pizza for this great lunch ‘n’ learn session.
