WKRN at Reduced Power

- Posted November 17th, 2021 at 2:54pm
I just found out that WKRN has lowered their power by half, yes I said HALF. They are only running at 500kw instead of 1000kw. I, myself, and two other people have noticed our reception within the past week has went down some or even out. They have filed with the FCC to let them know that they are running at a lower power. The reason for this is below.

"Nexstar Media Inc. (“Nexstar”), licensee of WKRN‐TV, Nashville, Tennessee, FAC ID 73188 (“Station”), hereby notifies the Commission that the Station was forced to reduce its authorized ERP to 500 kW due to a transmission tube failure. Steps to resolve the issue have begun but the repair has not yet been completed. Accordingly, Nexstar respectfully requests special temporary authority to continue operating at reduced power during the repair process."

So, if you have experienced any degradation in your reception of WKRN or WUXP 30.1, now you know why. Once I have found out that they have went back to full power, I will let you know. Until more news breaks, that's all for now.

That explains why I can't get their station, except at night with my dedicated Antenna/Tuner. Wonder when their tube went out? Why they had not moved to Solid State too is baffling.

IOTs are currently the best technology available to generate RF at the power levels required in UHF transmitter amplifiers. They are significantly more efficient than the klystrons they replaced. Every device is subject to failure and although IOTs are generally long lived, a "sudden death" is not unknown. IOT = Inductive Output Tube.

I live in Monroe county Kentucky and my living room antenna, a medium to large antenna shows no change in signal with WKRN. However I have a small plastic antenna for the bedroom and WKRN has been pixalating to no signal at times, normaly I get 2 bars on it in the bedroom.

My reception issues with WKRN have been going on for over two weeks.

I'm beginning to believe channel 2 might be installing a new transmitter. Replacing a transmitting tube should not take this long unless they are having a hard time finding a replacement?

I agree, seems a long time for just a tube. My living room large antenna still gets WKRN FINE but the small bedroom antenna just gets a good signal at night.

I know that everybody is frustrated with WKRN about this. My reception is in and out. I have e-mailed them over and over and still no word back from them.

I also e-mailed channel 2's head of engineering and received no reply.

Good. I'm glad it's just not me then.

I've been getting WKRN at full signal strength since yesterday. I'm hoping they are broadcasting at full strength again.

I don't think so, but I don't know for sure. I have sent them several e-mails and I haven't received not even one response, but once I find out, I will post about it.

It may be just the weather conditions. My tv was showing WKRN's signal at 100% before their tube failed. It dropped to around 80% afterwards. It is back up to 100% now, but I don't know why.

According to the FCC facilities database, WKRN is still under the Special Temporary Authority (STA) they filed back in November to operate at reduced power. Before the tube failure, the signal strength through our apartment community's master antenna was around 100 percent. It has been at 78 percent since then.

I can't say for certain. But I think WKRN is back at full power. I can get it better here in McMinnville now. S/N and Signal Strength are about equal on the 295 Degree Televes. I also get it (I'm sure temporarily), on my CM3020 too, aimed at 307 Degree. That would explain their outage earlier today too. Albeit not the best timing given the weather, and time of day.
