Re: STL setup

thank you @Deep Thought , @TPT , @Shane
are you changing studio or transmitter sites?
we're both changing the tx site and studio. I forgot to mention, we're operating an FM station.
Question: is the site 200m away going to remain as a backup?
no, new setup will be 4km away.

again thanks.. :D

Re: Audio static noise

-Are shields grounded only at one end? > what does it mean? As a rule the shields on the audio cables should be grounded at only one end of each shield. The common method is to connect the shield drain wires to signal ground at the load ends, and to leave the other ends of the shields floating. Tha...

Audio static noise

We have this noise issue for months now in our booth, everything had grounded already but this noise keeps appearing.
This came from our audio source (PC), but if we put the PC into UPS mode, the noise disappears.
Can somebody help me what to do? Is this AC lines related? (PC uses servo type AVR)
TIA
