Re: High Pitched Tone in FM Audio?

Is the transmitter still running the Digit or Digit CD exciter? If so, get ahold of service bulletins FM-535-WCF and FM-580-WCF from the Gatesair web site. Both bulletins address audio tones generated in the exciter caused by dried-up capacitors. Perhaps something was missed in the previous repair ...

Re: Wheatnet vs AXIA

Axia has many similar features, though silence-sensing is generally done through software like Pathfinder. If I'm not mistaken, it can also be done via SNMP. Really these days, AoIP preference is much like processing preference. All the brands do a great job, it comes down to which one you prefer. I...

Re: Barix levels

cheap (but reliable) boxes I'm not buying this excuse. If you have to add all sorts of band-aid level converters and adapters to a piece of equipment you're exponentially increasing the potential for failure while increasing the end-cost. I'd much rather buy one properly designed box that presents ...

Re: Barix levels

Unfortunately, it is normal behavior. They don't design those as reference levels (as you've noticed). There is no correlation between the input level of an Exstreamer and the output level of an Instreamer. My guess is because besides being cheap (but reliable) boxes, the Extreamer can feed all kind...

Re: Receive antenna height for translator

631 is a casual receiver. You need a 640 or 650. Sloppy engineering. Uh, can we be polite? I'm not a moderator here but I have to believe you are skating on thin ice. I, for one, would hate to lose your perspective and experience. That may be the only reason you haven't heard from a moderator yet. ...

BroadcastTools SiteSentinel 4

Howdy!

I'm trying to get the silence alarm on the SiteSentinel 4 to send an SNMP trap. Has anyone gotten this to work? Basically I want to tie a Burk status channel to it so it will dial out on the loss of audio. My Burk at this site is SNMP only, so I don't have much in the way of options.

Re: Missing FM pilot

I don't believe that is covered in the rules anymore. As long as the occupied bandwidth doesn't exceed 75kHz, I wouldn't expect much concern by the FCC. Any particular reason why it's bothering you? It really does not bother me much other than it is not really correct. Kinda like a really messy cab...

Re: AM CQuam Stereo

well... the ship is still here but why no one is taking advantage of it... but with a more positive attitude... Nah, the ship is not here. There are no new radios capable of decoding C-QUAM (other than a few HD models) and there are very few existing radios in the field. If you have the stuff, grea...

Re: New HD signal, BE equipment

Here's an HD-2 (SPS1) running on BE's Importer. You can adjust the level via the "Audio Gain" slider, or the Linear Acoustics software.

And here's where you's adjust the HD1 (MPS) audio level:

Re: New HD signal, BE equipment

I found that parameter in the software, but when I experimented with it, I could not perceive a level change in the HD1 signal, I did not check to see if it had an effect on the HD2 signal. If I remember correctly, the range for this field is -10 to +10, and I tried it at several settings, includin...
