As part of this effort, WJLA recently received temporary authority from the FCC to increase WJLA's ERP. The FCC approved this increase to allow WJLA to conduct testing to determine if the resulting stronger signals overcome any of the reception problems.
We encourage all to conduct their own tests and to share your results on this page. Your work will be instrumental in determining whether the FCC should approve power increases for high-band VHF stations.
As of today, WJLA is completely unusable from here in Elkridge, MD. It's gotten a great deal worse. Almost impossible to get a signal lock at all. Haven't made any changes at all on this end, just tried to watch RTN and decided to poke my head over here when I couldn't. It's not amplifier overload, WUSA 9 and all UHF channels are fine. Ideas?
edit: Hooked a tuner directly to the antenna, same issue. WUSA is 100% perfect right now, WJLA has a very strong signal but only a 35% S/N ratio and will not lock. It was an 85-90% S/N ratio previously (after adding a low VHF filter). Interestingly enough, a homemade UHF Yagi antenna with extreme negative gain on VHF 7 I have can lock the channel for brief periods of time. My guess at this point is extreme multipath (that Yagi I made locks 11 and 13 from the back without any issue too - I love that antenna). I almost feel bad for saying this, but from my location I think 52kW is actually too much! lol
Will try an attenuator at the antenna, even if it's just academic to do so. I don't need WUSA tonight for anything!
edit 2: Attenuator = no love. It's a variable 0-20dB attenuator. WUSA disappears completely about 25% on the knob, WJLA stays at 100% strength and a really bad S/N ratio until I'm almost at the maximum 20dB, then it disappears. Using a Y5-7-13 in an attic. Gotta be multipath that wasn't there yesterday. Again, I realize this is academic at best, and I've already decided to go with a FiOS Locals Only package (Sunday!!!) to solve my DTV reception issues with WJLA, WUSA, WBAL and WJZ.
Not worried about it for my own purposes. Just trying to provide meaningful feedback while I still have the equipment to do so in place. eBay firesale starts Monday! LOL.
