SOUTHWICK, MA—WGBH Educational Foundation has ordered two new VHF Parallax liquid cooled DTV transmitters from Hitachi Kokusai Electric Comark LLC for its WGBH Boston PBS station and the WGBY PBS station in Springfield, Mass. Both stations are in the process of a post-spectrum auction channel repack.

At WGBH, Comark will supply a multicabinet Parallax VHF band 1 liquid cooled transmitter on channel D5. The transmitter is designed for initial operation at 7.5kW TPO but allows for future power upgrades up to as high as 55kW should the station decide to maximize their ERP in the future. The transmitter cabinets will be pre-wired to facilitate a quick upgrade with additional power amplifiers and PA combiners.

In addition, Comark will supply another Parallax VHF band 3 transmitter on D13 for WGBY. The WGBY transmitter will be configured for 1+1 redundancy with a main/standby configuration. Each half of the transmitter can fully supply the required 13kW TPO with custom RF switching between transmitter cabinets. Both cabinets will be pre-wired to accommodate future power upgrades.

Comark will manage all aspects of both transmitter installations including program management, equipment delivery, on-site installation, and proof-of-performance testing. Both transmitters are fully upgradeable from ATSC 1.0 to ATSC 3.0 due in part the EXACT-V2 exciter technology.

“We expanded our Parallax product line from UHF to VHF band 3 and most recently to cover VHF Band 1” says Dick Fiore, President and CEO of Hitachi Kokusai Electric Comark, LLC. “WGBH/WGBY has been a long standing customer of Comark for many years, having previously purchased their original UHF DTV rigs from the transition from analog to digital. We are very pleased to be working again with WGBH Educational Foundation on this exciting project.”

“WGBH is looking forward to continuing our long relationship with Hitachi-Comark” says Emeric Feldmar, Director of Engineering at WGBH. “We have received excellent products, and support throughout the years. We purchased these Parallax VHF band 1 and band 3 transmitter systems for our WGBH and WGBY facilities that are being upgraded as a result of the spectrum auction/repack with capability to upgrade to ATSC 3.0.”
