Any experience with shielding your pickups?

John A did you say “Dimmers”
I hate Dimmers
The worst offender for 60 cycle hum in live sound. I cannot tell you how many venues that we have had a sound check and all is well until the house lights are dimmed. BZZZZZZZZZZZZZ
When I play out, it amazes me how many stage power sources have zero thought behind them. Even in brand new buildings, people refuse to do simple live sound friendly things (like power circuits not sharing neutrals with dimming circuits.)
In the good old days you could tap the buss of an electrical panel ahead of the branch circuits for a good clean power source. Thanks to NFPA 70E and a few deaths, those days are over.

"In the good old days you could tap the buss of an electrical panel ahead of the branch circuits for a good clean power source. Thanks to NFPA72E and a few deaths, those days are over." I remember sound men doing that.
Analog ain´t going to die, this new HD stuff is a bunch of smoke and mirrors as you need to be ten miles or closer to most big FMer's with IBOC for it to decode and on AM it's even worse, it takes up three channels rather than one which is against the FCC's own rules about harmful interference. This is the story of Collusion, one company twisting the FCC's arms and one Company investing in it: Clear Channel who owns many AM stations here in the US along with billboards. The radios aren't selling as for one thing you need outside antennas to get that 10 mile away station to decode. It's going to plow up in their face, the smaller stations are mobilizing against this abominations, believe me don't waste your money on a HD radio (HD mean hybrid digital not what they are implying it means) and BPL is just as bad, it will screw up ham radio all across the country if it gets implemented, the ARRL is fighting that one in court. They are trying to steal the ham bands from us. This stuff is not progress, it is politics and money run amuck, they are trying to knock all the little guys off the air with noise, legal jammers is what they are. If you live near NY tune to 700 or 720 during the day, what do you hear? That racket will be allowed at night starting Sep. 14th.
Ham radio was the only communication that reliably worked during Katrina a few years ago.
Drop Direct TV, the're are investing in BPL.

The Telecommunications Act of 1996 opened the floodgates and now its getting even worse. This all happened once before at the beginning of radio and AM was chosen as the main broadcasting medium even though FM was superior because the companies behind the money in radio had invested in AM. Its detailed in one of the Vacuum Tube Valley issues and is a very interesting article. Follow the money trail and you find where the decisions are made. I hope someone can stop them and let the hams keep their frequencies. My grandpa was a ham for years and years in NY and the Bay Area and I'm glad he didn't have to deal with any of that bulls**t before he passed.
Many big AM stations are completely against digital AM, expect to see some lawsuits in the near future. Less than 3% of the nations AM broadcasters are going to run it at this point.
I do not personally know anyone who has bought a HD radio. I do know some DXers' who have though and universally they are said to be next to useless unless you live next door to the transmitting towers and even then the difference is negligible.
There was no FM for 20 years after AM commercial broadcasting started in the early 20's with KDKA I believe. A man named Armstrong invented it during the 40's, he did have a hard time with it.
AM radio on the ham bands isn't going to die either, that is all I and many other hams use and many old time hams are going back to it. The ARRL also has a webpage for it. Digital just ins't going to work on AM radio, it will kill it if it is allowed to continue.
BPL is the big threat to ham radio, BPL: Broadband Over Powerlines. They are going to transmit broadband over the high tension lines creating all kinds of noise for miles in most of the radio spectrum including the AM broadcast and ham bands. The bought and paid for FCC is allowing this kind of krap because they are spineless appointed hacks who know nothing about communication. Yup, follow the money.... right into campaign coffers.

He tried to pickup a shield...well, badge...
According to him, he was picking up paper. In someone else's stall.
