Re: Audio Bandwidth of an AM Broadcast Station

Yah... I'd have to argue that one, too. 15 of the stations in my circuit are AMs. Most of them have attached FMs, or have recently received CPs for them under Revitalization. While diligence toward maintenance and compliance varies somewhat between the owners, the worst of them is only marginally de...

Re: Marti 950 MHz STL-10 spurious emissions

If all else fails & you don't have the time to bench it, I'd recommend Bohn Broadcast. I sent 3 pairs of those STLs out to them & they came back like new... better power supplies, replaced rotary switches, LEDs for the meter lamps & a bunch of updated parts. I know there are others who do this kind ...

Re: Translator Question...

This may have already been covered, but I'm still trying to figure out if the restrictions the FCC placed on these new translators were outdated before they were released. Even with "reduced facilities", wouldn't the 25-mile part of the "greater than" rule still apply to the translator's contour? Se...

Re: Harris/Gates support

I have mixed feelings about Harris. Last year, I did a re-freq on a DX-10. It involved changing capacitor types, and that required different mounting plates. They went out to the floor a couple of times and sent back pictures. It took some time to get the right combo, and the crystals took well over...

Revitalized AM Translators

Those of you who haven't yet built an "AM on FM" translator that was acquired under the "AM Revitalization Act" might find the following interesting. Having repurposed a few of these, pre-revitalization, I've run into some creative ideas from broadcast owners, revolving around what they can play, wh...

Re: BE AM-1A Power Supply

That power off / power on solution was a common, but temporary fix for that power supply. BE went to a different model with the same pinouts, but you only found out about it when yours failed. Don't have my spare handy, but I did confirm it was an off-the-shelf model. Power One, iirc. About half the...

Re: Broadcast Electronics Console Model 5S150 Issues

Since we’re waxing historical.... ,,,I said the Collins had better specs than the McMartin so we were perfectly happy to leave the Collins in place! If you're talking about the board with the near-vertical face, huge pot knobs and a 200+ volt power supply.... yeahhh... that wasn't one of McMartin's...

Re: back in the '80s had a 5S150

Were the filaments heated by coal oil? Back in the early '70s, I worked with / on two of those. They were great consoles... super headroom, tough, quiet, reliable and almost heavy enough to require reinforcement in the floor. The tubes weren't heated by coal oil, but were intentionally run a bit be...

Re: RF Spectrum Analyzer

I know next to nothing about Canadian communication rules, but looking at the analyzer you're asking about, a couple of things come to mind: First of all... does your regulatory agency require some kind of calibration reference? If so, there doesn't seem to be anything on the Ebay page that says the...

Re: Women Hearing Distorsion on Station After STL realign

The only Nicom I had got 41 dBuV on a 26 mile path with PR-950s. We got full quieting with stereo, but as I recall, we didn't have a lot of overhead. Drop the transmitter down much and the noise level would become audible. Sorry... don't know what that number was for us, but our "good" number seems ...

Re: computer audio interface - alternative to 3.5mm

I'm using Intel NUCs with Henry USB matchboxes to drive 2 FM and 3 AM transmitters. Sound is great, no computer noise, I get more than enough output to drive the AMs, and no discernible overshoots. Analog inputs... AES and analog outputs. About the only thing you can't do with them is generate a com...

FCC drops main studio rule

So... question(s). Given the current state of enforcement, lets consider a station that's dropped its studio and is feeding from an IP box at the transmitter. EAS is there, too. How would an inspector go about arranging a spot check? Call the national office and ask for an appointment? I didn't see ...

Re: DX-10 Controller Probs

Ditto on recommending you talk with Ralph. I just finished a frequency change on a DX-10. There are some capacitor-type changes in the new models, which we had to adapt to my client's rig. Ralph worked through the version numbers, went out to the factory and got some pictures of a model that was und...
