Members liko Posted December 18, 2013 Members Share Posted December 18, 2013 Hey guys, Just wanted to spread the word for those of you that don't keep your head buried in government reports or manufacturer's blogs. The FCC plans to auction the frequency bands for TV channels 37-51 (606-698MHz) to telecom providers in 2014, much the same way it auctioned off the 700MHz band in 2008. Again much like the 700MHz auction, it will be illegal to operate "whitespace" equipment such as wireless audio equipment in these frequency ranges starting as soon as 2015. This isn't getting the same mass media attention that the 700MHz auction did, because the change primarily affects only TV broadcasters and pro audio/whitespace users, unlike the DTV switchover which made every analog TV tuner in the country obsolete.This means that some or all of the following wireless frequency equipment will become illegal in the United States and will have to be replaced:Sennheiser:All Evolution, XSW, 5000 and 9000-series equipment operating in the B or G frequency bands. G-band users may be able to use their equipment legally, as the G band only overlaps the 600MHz band at the extreme upper end of its frequency range.Shure:All Axient systems will be technically illegal as the system can utilize the entire UHF spectrum (including the already-illegal 700MHz and 800MHz bands). However, the system is also flexible enough to allow operators to "lock out" illegal bands for any region; consult your user guide or contact Shure for assistanceUHF-R systems operating in the J5 or L3 bandsULX-D systems operating in J50 or L50ULX systems operating in M1SLX systems operating in L4BLX systems operating in J10, K12 or M15FP systems operating in L4Analog PGX systems operating in L5 and possibly in J6PG wireless systems operating in M7 and probably in K7All PSM series equipment operating in a J, K, or L bandSome users of Shure equipment in a "J" band may be able to find a useable frequency and continue using their equipment, provided that the channel is manually chosen and that features such as frequency-hopping are disabled.Audio-Technica:All 2000, 3000 and 4000-series equipment operating in D bandSamson:Airline systems operating in any N bandConcert 77 systems in any N bandConcert 88 systems in the C bandThis is not a complete list; to check whether your own wireless equipment is safe for use after 2015, examine the receiver. Most have a label containing information about model, serial number, and frequency band of the specific unit. If the frequency range starts above 598MHz, it will be illegal to use the equipment at all after 2015. If the frequency range starts below 598MHz but extends into the band, care must be taken to only use the legal subset of the unit's full frequency range.

Members Audiopile Posted December 18, 2013 Members Share Posted December 18, 2013 Well that would certainly bite... as I'd likely be looking at shoveling $3,500 worth of IEM's in the bin before even the first set of batteries needed changed (they're a bit more than a month old).At $1500+ per gig to use my wireless IEM rig before our govt. changes the rules... that would certainly take the attraction out of buying more wireless gear in the future.Or maybe the govt. will take some of the auction revenue and reimburse the effected citizens for the "taking".

This is an option being considered (and being pushed by Sennheiser USA in a letter to the FCC). Another is to maintain a few channels in the 600MHz band as "safe havens", allowing people with 600MHz-band equipment to keep using it; the trick there is that you may need a license to operate on those channels, because the groups pushing for that concession are the production companies that need wireless for sports broadcasts, TV shows, theater productions, etc. and they want those available channels for themselves, not the band down the street at the dive bar.

Members dboomer Posted December 18, 2013 Members Share Posted December 18, 2013 First the good news ... it might not be this bad. Second the worse news ... it might be worse . The exact details aren't all worked out yet. The writing has been on the wall since 2009 but no one usually pays any attention until their systems shut down. It actually all started in 1997, but who's counting Liko ... what you are talking about is stage 1 and there is a stage 2 to follow. The plan is spelled out as part of the National Broadband Plan http://www.broadband.gov/plan/executive-summary/ The FCC has been planning to free up 500MHz of bandwidth for broadband internet to be completed by 2021. Currently there is about 220 MHz of bandwidth in the TV UHF band and 120 MHz of that is scheduled to be taken away and reassigned. What's left will have to be shared with Over-The-Air TV broadcasters and likely some kind of Smartphone/Cellphone/voip systems. Sennheiser is already saying that it will not be possible to move everything in the 600's down to the 500's (like the 700's were shifted down) because the bulk of the TV stations currently operating in the 600's will get shifted down so there won't be much white space left. ... http://www.prnewswire.com/news-releases/sennheiser-petitions-fcc-to-compensate-owners-of-wireless-microphone-equipment-as-spectrum-faces-repacking-for-second-time-233498951.html The good news here is that when they sell off the 600's part of that money will be paying down your income taxes (on a personal level). http://www.finance.senate.gov/newsroom/chairman/release/?id=c42a8c8a-52ad-44af-86b2-4695aaff5378 Link to comment Share on other sites More sharing options...

(looking on the bright side here) Link to comment Share on other sites More sharing options...

Members agedhorse Posted December 19, 2013 Members Share Posted December 19, 2013 VHF can be fixed or frequency agile. Nothing wrong with VHF except the limitations on bandwidth (few available channels simultaneously. Link to comment Share on other sites More sharing options...
Members RoadRanger Posted December 19, 2013 Members Share Posted December 19, 2013 The 14 channels available with the Line6 stuff would be plenty for most bands. I don't understand why they don't make an IEM? They'd sell a bunch . BTW am I the only one who hasn't ever heard a Line6 guitar amp that sounds good ?

All the ones I've ever seen have been fixed-frequency using a crystal. Link to comment Share on other sites More sharing options...
Members agedhorse Posted December 20, 2013 Members Share Posted December 20, 2013 The problem with the higher bands is that range decreases and losses through materials like flesh are much higher. Link to comment Share on other sites More sharing options...

This. 5.8 has serious range and penetration problems, and in anything larger than a small club, you'll probably end up with the wireless receiver on the stage side of your snake (if you have one; my church uses wireless for almost everything, because it's seen as better than trying to hide cable runs in a large stone sanctuary) Link to comment Share on other sites More sharing options...
