Think I'd call BE and talk with them about that exciter fault light. If the board has gone and your shooting miscellaneous odd stuff through the transmitter, VSWR seems like a reasonable indication. Beyond that, given this is a strange one, I'd put a dummy load on the transmitter and bypass everythi...

That's no surprise, Larry. KGEZ is operated by someone I knew many years ago, here in the Seattle area. Back in the late '70s, John Hendricks was a local announcer in these parts. He was a pro to begin with, but worked with many of the area's best managers, owners salespeople and programmers. He eve...

That picture exemplifies one of the things I appreciate about having entered this business in the '70s as a teen, when everything was made from discrete components, the rigs were full of tubes, the fans were big, the exhaust was hot and the voltages were respectably high. Back then, a lot of trouble...

but my attitude about the company and their commitment to support has drastically soured, to put it mildly. And when Ralph Wegman retires, there will be basically zero knowledge of these transmitters left at GatesAir. Agreed. His support made me much more comfortable, taking on the re-freq of a DX-...

If you have no technical experience, this is not the place to start. If you do, then you need a list of parts that would be required, plus the frequency change procedure for the Gates series of transmitters. Gates Air likely has this material available, though the transmitter's documents no longer s...

They've done that to me, too. It stopped when I sent logs from two of my client stations, 175 miles apart, running the same format... with exactly the same problems at the same times.

I have a client with a small-town 500 watt AM DA on 790 in conductivity 8 land and the 2 mV/m extends 55 kilometers (34 miles). If it were running 5 KW it would be 94 kilometers (58 miles).

How high up would you have to put 250 watts in order to get that kind of coverage.... if you even can?

Now look at Section 74.1263: (b) An FM booster or FM translator station rebroadcasting the signal of an AM or FM primary station shall not be permitted to radiate during extended periods when signals of the primary station are not being retransmitted. Notwithstanding the foregoing, FM translators r...

I second the BW equipment. They've gone to a new display, so that issue has been dealt with. For the money, I'm not sure you can beat the feature set in the V3 versions. As noted, they are fully web-enabled, are able to email out RF and modulation-related alarms (assuming power is available), and in...

I have been encountering the same problem with DX10 PA's. Its a constant occurrence when you have an unstable power source ( power fluctuations ). Usually, only 1 MOSFET is burnt out and the fuse from the side where the RED led lit up. Busted MOSFET exhibits a shorted circuit reading in VOM tester....

Sonetimes a faulty fuse holder will cause the fuse to heat and fail. That would seem a rare occurrence. Matter of fact, in my experience, I recall only one case where I've lost a fuse due to a failed holder. That was the main fuse on a vintage Nautel Ampfet P400. It's still in daily service, btw...

Wondering if engnewbie found the problem and might let us in on the fix.... Over the years, my Gates-X transmitters have presented me a cornucopia of challenges and provided many hours of relaxing solitude, whilst contemplating each one ( :roll: ). However, blowing FETs, merely with modulation, has ...

The M-Audio "Audiophile 192" was a popular card. I bought a bunch of them and, since none has ever failed, still have them in use. You can find them on Ebay fairly cheap. They're PCI cards though, so you need a computer with the older sockets. SoundBlaster has newer cards that pass 192kHz. The Maria...

I use Stereo Tool in several installations, both AM and FM. If you need the program to produce stereo composite, you'll need a computer that can handle the physical size of a 192kHz audio card... either that or a 192kHz USB-interface. If you're in a competitive environment, that gives you the use of...

BSI has always been fairly conservative about how you use / connect their products. Years ago, when I first spotted them, I noted Simian's purported ability to run multiple instances of the software on a single computer. Asked how many the system would tolerate, they wouldn't give me a fixed answer....
