Received a phone call on the weekend to attend a tv outside broadcast van that was having "Issues" with their RF talkback. I supply lots of trunkey talkback systems that are plug and play to tv providers here in Melbourne.
The system I went to look at has multiple Tait TB7100's bases running at 5 watts continous tx into a TX Multi coupler, has an RX multicoupler, some RX amps and numerous cavities on the rx side. Simple enough configuration and it had been working perfectly.
The audio guy onsite tells me the audio isn't loud enough from one of the bases and shows me how he was trying to adjust it (remember this is audio back into the truck).
He had undone the locking screw on one of the cavity filters, and was hitting the adjustment rod (forgive me I don't know alot about cavity construction so I don't know what you call that bit) with a pair of very heavy pliers.
His comment was "see it gets softer when I whack it all the way in, but when I pull it out again it doesn't get loud enough. Can you make it louder ?"
Hmmmm, yet another case why some audio assistants should not be allowed anywhere near anything rf related that is not a wireless microphone.
Glad it wasn't my equipment he was belting.
Still laughing
