KYZS Tyler: Humming Right Along

I lit up my old stereo cabinet yesterday afternoon and found a rather noticeable noise coming out of 1490. To this ear, it sounds like a short somewhere that's causing a rather audible electric "hum" going out OTA. Been awhile since I've turned on the old Zenith, which is the only receiver I use to access Tyler's primary AM for K-DOK, so not sure when this issue arose.

Just so happened that my daughter carried me to Mc Kay's Ranch House yesterday, affording me an opportunity to fiddle with her receiver and dial up 1240, the actual KDOK. No hum. No hum that I can perceive on K239CB, either. Nor the 105.3 translator in Kilgore.

Seems relegated to just 1490. Thought I'd mention it, knowing that Chuck comes by RD and visits the site regularly. I typically have 95.7 tuned in on all the other units, but the cabinet does far better on tuning in the AM.

By the way, I thank you kindly for the addition of Black Sabbath material to the K-DOK library, good sir! 🤠👍

I do come here from time to time. Because of your post, I spent yesterday afternoon in Tyler at the transmitter site. You are right, there is a slight buzz (I wouldn't call it a hum) on 1490. It is very low in the noise floor. As far as I can tell, it is caused by the close proximity of two other transmitters at the site. (just Inches away). There is a lot of RF in the building. The audio feed is clean and all the processing equipment is clean also. BE, who made the AM transmitter uses an active balanced input. I suspect that is the problem. The next time I go there, I plan to install an audio isolation transformer as close as I can to the input of the AM transmitter. Maybe that will help, since RF doesn't go through transformers very well. All that said, I changed some of the AM processor settings to try to mask the noise. As I left, I really couldn't hear any objectionable noise in my car, which has a pretty good stereo. Road noise totally masked it. The station sounded pretty good to me, at least as far as AM radio is concerned, Of course the FM sounded quite different. Have you listened to anything else on your old Zenith? If it is an actual hum, not a buzz, then I'd suspect that the filter capacitors, need replacing. It happens.

Of course, this also poses the question, "Does anyone actually listen to AM when the same programming is available on FM as well? Enquiring minds want to know....
 
I, of course, get a great joy from hearing the music as I originally did on that cabinet, in glorious AM. It can not properly separate 95.7 and 96.1, so to listen to K-DOK on that unit, is has to be 1490. I have dialed up 600 on it and KTBB has a strong, robust sound. Should, too, given it's our strongest AM in the area. 1330 is basically unlistenable, but not a format that is my cup of tea, so no loss to this household.

Chuck, thank you for your hard work and the time spent dealing with the issue. I'm probably the only soul in Smith County actually listening on the primary, but I kinda grew up with 1490 K-DOK, so it's really more about rekindling some ancient memories for me. I'll be sure to warm the cabinet up this evening after I make it back from the gig, crack open a cold Miller Lite, and give the adjustments a listen. Thanks again!

Correct... If we ban a user it will put a line through their user name and put a "banned user" note underneath. When they request their data be removed for COPPA law compliance this is how it is handled.
