Let’s have some fun with a “Band Plan”!

I hear a constant litany [usually from the “HD”-enthusiasts here] begging for a workable alternative solution when the flames roar over AM band issues. A few have “stepped-up” and presented their suggestions for digital band creation and AM rearrangement. The contributions have been interesting and with commendable merit; but in many cases, their start at point-A never reached a comprehensive conclusion at point-Z. So let’s take a stab at a really-sweeping “Band Plan” – the broadcast-equivalent of “Nation-Building” if you will. I’ll toss-in the “first draft” and take the “incoming fire” – and I can confidently-predict that explosive ordinance is headed my way!

As for any constructive attempt at band-planning; we need to first agree that the FM status quo will suffice for the reasonable future. IBOC will remain and “fight for its right to party”. Please have NO illusions that any TV-5 or 6 turf is headed for a digital-FM radio stick in the future – that spectrum is too-valuable in political eyes, and the government has handed corporate radio more than its fair share of food stamps! The “pols” are simply more-interested fuel prices, border-crashing, and over-heated Polar Bears! On the other hand, the AM band represents a valuable national resource; is in dire-need of resuscitation; and is deserving of a second chance in life.

[1] As for any *new band*: Let’s pursue the do-able and think 26 MHz in digital aac+ [for receiver synergy with IBOC]—a so-called “local-service digital D-26 band”. [2] While the FCC is giving up all those additional coffee-breaks, they can summarily-DISMISS ALL 14,000+ FM translator apps [they’re cancelable secondary services anyway] and continue the “freeze” on their non-productive future. [3] Create a NEW PRIMARY FM-assignment class [possibly call it “TA” for “Transferred Allocation”] with varied maximum ERP guided by Section 73.215 contour-protection rules... Think: “translator/LPFM hybrid and AM catch-basin”. [4] Grant “primary” status to FULL-FACILITY LP-100 FM stations—designating them as a “must relocate” by all future full-power and “TA” station apps AFTER a reasonable window to allow for the establishment of required Class TA facilities. Now, I think we have more-than-addressed the “local radio” concerns with the prior initiatives!

There is no-better candidate for an all-digital augmentation than the current AM band; but I’d question within the contemporary climate whether practicality could survive the brutal politics. Given the historical priorities of the FCC; the coverage capability of analog AM; and a heightened domestic threat – I can’t imagine the Regulators permitting a full-scale antiquation of the analog receiver base. [5] I’d suggest approval of a voluntary “proceed at YOUR own risk” provision on a station-by-station basis for one consciously-selecting a digital-only mode aimed at capable tuners; and I’d call for a digital AM receiver “type acceptance” that mandated that mode be included with hybrid-digital capability.

A technical game of Hop-Scotch or Shuffle-Board on the AM band ISN’T going to cut it... The “herd” HAS TO BE THINNED!!! This is NOT a matter of “MAYBE”—“MUST” is a more-appropriate term! No doubt this will require the proverbial “dangling carrot”—a band-bait ‘n switch if you will... And NOT at the peoples’ expense of additional corporate radio welfare and entitlement. The first challenge [related to radio] for the incoming FCC is to slam the brakes on that eight-year gravy-train; and progress beyond the mere visitation of genuine RE-REGULATION. As a political Libertarian, I can’t believe I felt it necessary to utter those dirty words – but corporate radio has worn-out its deregulatory welcome mat.

[6] To creatively-force the surrender of deficient AM facilities [in large and small markets alike], The Commission must first re-write with total retroactivity—the ownership rules that promoted this promiscuity in the first place – THEN display the carrot which becomes damn-attractive in the absence of ANY way around the *new* rules via so-called *Grandfathering*.

Continue to operate in as many locales as you can finagle-the-finances; but in ANY market where there is a “second voice” – the *new* cap is 4:2/2. If you're CCU [or their ilk] and own 8:4/4, 7:4/3, 7:3/4, 6:4/2, 6:3/3, and so-on down to within a silly station of the carved-in-stone limit of 4:2/2 – you call the media broker and sell – SELL – SELL! Here’s where things get “creative” and the carrot comes into play: If Mr. Blackburn gets you down to 6:4/2 or 5:3/2; and you’re really sentimental about the FM loss and disfavor the AM baggage; then TURN OFF and SURRENDER the license for those AM animals—put them humanely to rest – and earn a “credit” to maintain a third or fourth FM! [7] Any remaining AM is eligible for a local-digital D-26 simulcast allocation. NO “TA” will be granted to a large-market AM/FM multi-station cluster [I doubt one would fit within those circumstances anyway].

Sha-zaam! ...You’re almost back to a “cluster” again! ONLY the AM “bottom-feeders” are missing... I doubt the licenses of WABC, WCBS, WOR, WLS, WBBM, WGN, WLW, WSM, WSB, WBT, and hundreds of other capable compadres are headed back to The Commission ANYtime soon! BTW, NO smarmy AM station sales to the usual suspects who always seem to surface when “scraps” appear on the landscape [reference the AM expanded band]. YOU MUST TURN THEM OFF to enjoy the additional FM credit! Remember, the mission here is “herd-thinning”—not “herd-hiding”!

[8] Large market STAND-ALONE AM stations may seek an FM Class TA service [where possible] and local-digital D-26 allocation to SIMULCAST the AM. The “TA” cannot “travel” if that station is purchased by the operator of an in-market FM station. Stations licensed at under 250-watts at night may only operate within their specified daylight hours or a minimum of 6AM-7PM if a “TA” is granted.

Now that the big guys are in toe – let’s shift to the exurban, medium, and small markets where the AMs tend to be “Blue-Light Special” candidates anyway... The same rules above apply. [9] You may exercise the option to carve out an additional chunk of coverage IN THE FM BAND as a “TA” despite your FM circumstances. Scenario #1: You have a 5:3/2 count and wish to silence both AM stations – saving the third FM from divestiture and gaining an additional “TA” for a total of FIVE FMs. Scenario #2: You have a 4:2/2 count and wish to silence one lame AM station – gaining a “TA” and thus a third FM for a count of 4:3/1. [10] Any remaining AM facility and Class TA FM may seek a local-digital D-26 allocation for simulcast. [11] Standalone AM rules are the same as those detailed for large markets above.

Now imagine all the feeble major-market high-band 5kws; smaller-market 500-watt-day/37-watt-night typically-simulcast pea-shooters on the former Class 3s, Draconian-DA interference-machines, day-timers nearly-everywhere, and even “graveyards” that will be going bye-bye! Once cleared, the AM band could be sanely-reassessed.

[12] In the event that an AM station operates in a market with NO FM service licensed TO that community; this station qualifies for Class TA FM and D-26 local-digital service without surrendering its current AM for a predetermined period. There will be NO simulcast requirement for these additional facilities. Stations licensed at under 250-watts at night may only operate within their specified daylight hours or a minimum of 6AM-7PM if they are granted a “TA”.

[13] The C-QUAM AM-stereo system will remain the standard. Why is it that any proposal regarding AM-stereo seems to draw the unlucky number :'(

[14] FMeXtra, CAM-D, and any-other compliant transmission service will retain de facto authorization, but its implementation will remain the responsibility of those utilizing its operation [within the rules] and ELECTIVE to those designing and marketing capable receivers.

[15] The Commission WILL CODIFY minimum feature and performance standards after determining an appropriate receiver-class and retail price points regarding ALL-band reception [including D-26]; digital capability [iBiquity IBOC hybrid digital/full-digital on AM/FM if elected and digital D-26]; analog FM-stereo; NRSC AM bandwidth mask; C-QUAM AM-stereo; and possibly variable-bandwidth A-Max. Whether Sony or CTX; the FCC must mandate minimum receiver requirements. Less face fact: The U.S. is their most cherished market; so are they [in reality] prepared to surrender it by their failure to comply. If radios are fast-achieving integrated and DSP platforms; programming these “chips” into compliance shouldn’t be a daunting or expensive proposition.

If you believe that the AM band suffers from terminal disability due to over-population; and you believe that ownership limits are too high to regard the public interest – then the preceding paragraphs are a proposition worthy of debate. The “herd” can ONLY be effectively-thinned by directive [plus the carrot[/i] as a compensatory lure]. You cannot expect the former without the latter. Those few enjoying the current status quo will certainly bluster; but isn't this fair, effective, and within the realm of the public interest? ...YES, YES and YES! Are there holes? Is it ripe for nit-picking? ...YOU BET! But at least we can begin the dissection here... And that’s more productive than an AM-band autopsy!
 
Hippo came up with some good suggestions on his well reasoned and interesting post. One thing many of us agree on is that any digital system on the AM band should be in a all-digital format. Some posters here insist that an analog backup is necessary because of the fragile digital signal, but comparing the analog and digital signals is like comparing apples and steaks because of the disparity in power levels. The efficacy of the A and D signals should be tested with equal power levels. IBOC should mean what is says: In Band On Channel! I am convinced that the current system is unworkable for the great majority of the stations. Perhaps it works satifactory for the blow torches because of the high power and co and ajacient channel protection, but that is a very small percentage of the stations. I could see some wisdom in allowing stations to broadcast an all-digital signal on the extended band, and perhaps down to 1500 as long as it fits into the current allocation scheme without causing interference to an existing station. Power levels could be the subject of another discussion.
 
I think that the 26 Mhz band seems like a good idea (to move the digital signals off of the AM band, or to allocate to translators, etc.) but what about the propagation characteristics of this band, especially during solar max, since it's like CB 11 meters or 10 meter ham band? Seems like a higher frequency such as the "old FM band" of 41 - 44 Mhz or other portion of the VHF band would be more feasible...
 
It would except we already have a RPU band in the 26MHz band no one else really wants. I agree the 46MHz band would be better, however, the 26MHz band is very underused and "worthless" to most so getting the FCC to do the right thing with it would be the lesser path of resistance though their endless red tape.

A pleasant thought about doing any digital service there is you'd either get it or you wouldn't for the most part. It wouldn't be a bunch of band noise when the band goes apecrap. Also, the analog would still be there at the normal MW band to roll back to when probigation got too wierd. NOTHING about this IBOC stuff is anywhere close to perfect, rather it's a comprimise of some sorts. I personally think nearly anything would be better than the current AM digital mess.

Since it's an international shortwave band, doesn't any frequency assignment in the 26 MHz band have to be coordinated through the ITU?
 
Finally got around to reading this one...

Some very good ideas Hippo! I especially like the idea of creating practical incentives to turn AMs off for the good of the remaining stations.

That said, I see some problems. The biggest is the mom & pop stations. Way too many of them haven't put a dime into technical improvements in years if not decades. I don't have a very good understanding of super small market radio, so I don't know why that is. I can only assume something has changed the competitive landscape for them. I've spent some time visiting very well built micro market facilites. Places that were built like a tank in the 60s or 70s and haven't seen a technical upgrade since with the possible exception of automation gear. The same people that can't afford IBOC probably can't afford a new facility on a different band.

There are a lot of places throughout the country where new FM allocations for small towns aren't a problem at all, and the local radio operator could easily get another FM signal, but he doesn't. He sits there with his little AM/FM combo built in the 60s. There are some very real costs involved in putting even a class A FM on the air, and I'm guessing that's why you don't see small town, mom & pop FM/FM combos.

If you could just figure out a way to create incentives powerful enough to get a lot of the AMs in Nowhereville, USA off the air, you'd go a long way toward solving the interference problem. You'd solve a lot of Post Sunset Sports Authority problems for sure.

There's a simple reason that a small-market AM owner would be hesitant to add a new FM allotment.

If the existing owner determines that an FM channel is available and files a petition to have it added as an allotment (which requires engineering and legal expenses), the FCC will then put the construction permit up for auction, inviting new competitors into the market. So if we want these small AM stations to move to FM voluntarily, let's make sure they're guaranteed access to the FM band without risk.

Absolutely correct. The auction process may have helped our government pay for some of their expensive ways, but it has done nothing to really help radio or the communities it is supposed to serve. The auction process just made stations a commodity that are profitable to buy and sell. That's how we got to this point.

A big improvement would be to impose some reasonable ownership limits and do away with the "highest bidder wins" situation. How about awarding CPs on merit, not money?
 
OK, it's a solid proposal. I'm sold. So who wants to start the Petition for Rulemaking?

(Hint: Don't look at me.)

- Hey, maybe the NAB could help us, oh, I forgot; they're too busy worrying about satellite radio while their own house is on fire!
 
Something else that crossed my mind today was to keep the AM band all analog. Then, use the 26 Mhz as digital only. The digital receivers available would receive the digital signal on 26 Mhz, then also "map" to the analog on the AM dial, in a somewhat similiar way as HDTV tuners on TV. Should the digital signal become "unlocked," the default would be to the mapped analog frequency back on AM....

That would probably work. Since it is simple, it would never sell....

Well now that's a very interesting idea. And you can substitude any band for "26 MHz", really. Whatever's free. Hmm, I wonder if IBOC could design that into their current scheme? Imagine a seamless blend from an HD-2 to its analog AM counterpart. ;D

I had an idea a while back of merely dividing the current band into three parts: an analog only far-regional wideband stereo service, an (optional) hybrid analog-digital regional section, and an analog-only (optional) stereo community/city service band. That, combined with hippo's suggesting for weeding out some of the signals, would really clean up the band. Most stations wouldn't have to move places, just turn off HD if they are on the low or very high end of the dial.
