Re: The high leg

Correct me if I'm wrong, but I think the OP was referring to three-phase closed delta with a high single phase leg, sometimes called a "stinger". Pretty common around here. Two of the single phase legs are the normal 120V, the high leg is around 208V. You have to be careful not to use that leg for ...

Re: Harris FM-25K issue

Any chance the power is blinking off for a few seconds or there is a power quality issue? I think that you said that sometimes it required physically retuning the IPA input to clear the fault but was just wondering if the BW might lock on wrong freq briefly at startup or burp off during a power qual...

Re: Low Power AM ATU question....

Depending on the load, it _might_ work. However a 7m base loaded vertical on any AM/MW frequency is going to be VERY, VERY narrow bandwidth and probably very reactive at a very low base resistance. If he is using a Part 15 type antenna that can be tuned to something close to resonance by careful len...

EnergyOnyx MK5.5 Internal Harmonic Filter Info

Hi all, I have been contacted by an engineer in Argentina that is working on a MK5.5. I have a .pdf manual but it doesn't appear to have any information on the BernieBuilt filter that he used in later units (including the ECO iirc). The early low powered MK series appeared to have the normal coaxial...

Re: adjustable Studio desk

But in today's AOIP/IP world, a couple of Cat5 cables properly routed (physically) would probably survive very well... Multiple runs of Gepco 16pair maybe not so much. Keep in mind that I work outside the top 100 markets. In my market a couple of clusters have digital consoles, but most of the mark...

Re: adjustable Studio desk

In nearly 50 years in this business I have never seen an adjustable height desk in a studio. Consoles (and sometimes other equipment) are often cabled to punch blocks, and the mult cable used is designed for fixed installation, not for repeated flexing. But in today's AOIP/IP world, a couple of Cat...

Re: AM site and Solar arrays

Truth... Several, several years ago, I briefly worked with a station that had rented their DA site to a solar farm without regard to AM operation. It was a hot mess. The solar installers tore up the ground system, the solar didn't work in high RF and the DA was extremely unstable. As I recall, the o...

Re: Pirates captured

UPDATE TO MY XLATOR INTERFERENCE SAGA POSTED EARLIER... Yesterday I finally got a nice day with nothing much better to do other than chase around middle TN looking at FM signal strengths and antennas... I used a 1/4 wave FM vert mag mount and a Pira P275 for relative measurements. Imagine my surpris...

Re: Women Hearing Distorsion on Station After STL realign

That you're hearing complaints from women first isn't a surprise. Research about that goes back, at least, to the Schulke SRP Beautiful Music days and, to some extent, drove the technical requirements the company imposed on its subscriber stations. Most women are very sensitive to (and intolerant o...

Re: Women Hearing Distorsion on Station After STL realign

What do you hear? As was noted in the other thread, 26dBuV is very low. I would not be surprised if the signal is noisy... What does it sound like with nothing playing? I'm not sure what is considered to be minimum full quieting signal level but I have 3 or 4 of these on paths from 4 miles to about ...

I had to jump back to the picture in the previous post a couple times before I realized the picture above is a split-screen of both ends of the system. :) I was snickering initially at what appeared to be a RSL and TSL90...

Re: GR EAS-1/CAP-DEC-1 issues

Also make sure you sign up for the IPAWS Email Digest. They will send a notification when a test is missed or an error has occurred on their end. It's very handy. Where do you sign up? My google-foo isn't working on finding a signup page. I am signed up on the sbe-eas reflector but the failure wasn...

Re: GR EAS-1/CAP-DEC-1 issues

I don't have an IPAWS down/up notification either. The Sage web interface can tell you if IPAWS is visible. IPAWS is (and apparently was) up and there isn't the usual down/up log entry but also no entry of test received at 2pm. There are numerous other IPAWS tests received over the past few weeks s...
