Satellite Metrics

Gents: We have a pair of satellite receivers that read rock steady at 50% signal level but Eb/No & C/N readings wander around (front panel LCD). Some days the Eb/No wanders up and down by a whole db. I have not observed this behavior before in my experience of working with Wegener/IDC or any satelli...

Translator Receive Signal Booster

We have a translator broadcasting on 96.3 fed off air from our 100k main signal 60 miles away. We are only getting 2 bars of signal on our Dayton 210 which feeds a PTEK 300ES (brand new). Of course we don't sound very good. We've got a radio shack a stones throw from the site so I bought an old scho...

Re: BE FM25T Tube Change issue

JammerDave:

No HD.

Don't have access to a SpecAN. At this point I think I would have to put the "interference complaints" in the not related category. Shes been rock steady and humming right along with the new tube.

STL Overshoot

I have noted high modulation on the modulation meter of my FX50 exciter. Somewhere in the neighborhood of 10 to 40% over. I am doubtful of the meter as I am not hearing any evidence of this much over modulation on-air. I believe it is a Moseley 505 STL receiver. In the past I was able to power cycle...

Re: FM Stereo Pilot

Seems like it might be easier to take our back up processor, an Orban 8100A, to the translator site. No?

Re: BE FM25T Tube Change issue

The solid state transition can't happen fast enough for me (of course this takes all the fun out of it 'eh?). Give me a Nautel now! ;-) Seriously at $1, 500 to $7,000 a pop for a tube solid state is a no brainer if you are buying a new transmitter. RGORJANCE: I attempted the rebuilt Econco 3 times. ...

Re: BE FM25T Tube Change issue

Thanks NECRAT. I was wondering where my post went. :-)

Kelly:

Big thanks. Exactly the detailed information I was looking for.

From step 11 you stated: "the target AM noise should be >-60dB". Do I interpret that that correctly to mean less than or equal to -60db?

Re: FM Stereo Pilot

Rodeo: Thanks for the valuable info. Excellent input. In my tests of the JMPX software and Virtual Audio Cable software with all volume controls maximized the input/output levels were extremely low. In this test case input audio was from .wav file and a live audio stream. Looks like a $100 to $200 h...
