we could lobby to get the antenna restrictions loosened and an upping in power on 1750 meters. might have a better shot there.
or again open up 1710,1720,1730,1740,1750,1760, 1770,1780 leave 1790 as a buffer between 1780 and 1800
up the power to 200mW input and no antenna restrictions.
leave it up to manufacturers as to whether to include that band in their radio lineup.
this will assure it remains a hobbyist band and frequencies won't be gobbled up.
again there would need to be a transmitter limitation per individual under this rule part. this limitation should apply to this rule part only and not tx's running on fm or in carrier current. this will leave room for everyone. it's already been demonstrated that 3 100mW tx's with a long ground lead can cover an entire town and carrier current could be used to supplement this service by filling in building penetration.
this has a good shot too.
broadcasters should have nothing to fear from people running on a band that not many cheap radios are available for.
Some good ideas there Rev. Especially the no antenna restriction and bump up the volume another 100mW...though I would propose 4 or 5 PEP.
I like the idea of expanding the AM band up to 1780. But the idea of letting radio manufacturers decide to put that into their radios or not...the last time the "market" decided that not only shoved the dagger in deeper to the death of AM, but took HI-FI stereo AM along with it.
I am not sure what good it will do to be transmitting on frequencies the public will not be able to even tune in, or have to go out and hunt down a specially equipped radio, which will no doubt be more expensive than the abundant radios filling the shelves. Would the extra cost to the radio public be worthwhile to hunt down that particular radio to tune those extra frequencies...will they find something there to justify that extra cost...or find nothing but a bunch of static, buzzing and noise like that on the current LW band?
I don't know how well it would fly..if even make it to the runway for take off.

A gross and unreasonable condition exists, which has only been slightly hinted at, and that is the holding of radio licenses by religious organizations.
The issuance of a radio license to a religious organization by the FEDERAL communications commission is a church/state violation because by doing so, the government in essence endorses that religion.
There's a further problem in churches using 100% of broadcast time to spread their message, because churches/religions are a brand of product/service being distributed by a corporate agency. They are using their license to transmit 100% commercial messages for themselves, with no opportunity for other programs or messages from other points of view.
Imagine a station owned by Ford Motors broadcasting 100% commercials about Ford with no other programming. That is what religions are getting away with.
A third issue is the peculiar freedom from taxation enjoyed by religions, while they hoard wealth and property and only provide small band-aid stage plays about "helping" the needy. If they were helping the needy there would be no more needy. Churches are businesses and should be taxed.
Look at it this way.... you are a member of a church, yet you are taxed. What? So in other words they are not sharing their tax free status with members. Maybe you only think you're a member, as long as you pay your subscription.
Religious broadcasting is interference by definition.
"Maybe you only think you're a member, as long as you pay your subscription.

As they say...the devil is in the details. The devil loves using distraction to keep attention away from the details so no one will notice the real deal underneath the sheep costume.
Crafty sons o #@%#$$.
Make it all look good and nice up front, no one notices the dirty work behind. WOW..sounds a lot like politicians!
RFB
i look at it this way. it will force us hobbyists to get receivers into the hands of the local audience.
we can build small add on converters that covert this segment down to a lower am band segment or from longwave up to am etc. if we leave the manufacturers out of it and we get the receivers into the hands of the public our selves this helps assure it will stay a hobby band as it won't be economically viable for corporate america to such up all the frequencies as has been don with FM and lpfm.
this is the way radios started in the 20's. broadcasters built their own transmitters and built receivers for the public to listen to those broadcasts with.
"we can build small add on converters that covert this segment down to a lower am band segment or from longwave up to am etc."
Another good idea. But you do realize those converters will have to be certified. And there is the public education factor and willingness of said public to fumble around with their buried deep into the dash radios to put this converter in between the receiving antenna and radio antenna input.
Most likely will have to be done through a car audio installation specialist.
Home receivers would not be that big of a deal, but not everyone is listening to the AM radio via their home theater systems or large stereo systems..but via table top radios or clock radios. Not so easy to hook up a converter in those situations.
Basically for the public..it will all have to be a "turn on and it works" kind of deal. With the level of impatience these days in the general population, the tiny section of those who would venture into the hell holes behind the face of the dashboard or tear apart the table top radio to tie in a converter...ie us radio kind...I am still not quite sure how all of it would launch and maintain momentum and be successful.
RFB
since when do converters and receivers need to be certified? there is a guy building and selling uncertified am stereo receivers, bet he could be convinced to add this new extended band into his receiver. especially if we run cquam and tout alternative or old formats not seen much on commercial radio. i'd forget targeting cars. this would be mainly a stationary thing more so than mobile thing, but he could probably build a cquam converter for mobile use as well that features this expanded band.
Every radio receiver made has to be certified under the Part 15 rules since they use and generate radio frequency energy within. Thus they have to comply with our two favorite (a) and (b) people.....
..(a) this device must not cause harmful interference.
..(b) this device must accept any interference including interference that may cause undesired operation.
This includes converters. They use harmonic tuned circuits just like a translator for FM does and creates a new frequency, again generating RF energy within to function, thus they will have to go through the ringers of making sure they operate as (a) and be open to anything like (b).
The guy selling c-quam receivers...doesn't do that anymore..has not done so for quite some time...about 10 years or so. He no longer makes the transmitter either. The only other place I know of and is outside of the US is ASPSYS which makes an AM C-QUAM decoder board, by itself it is not a receiver, but merely a decoder using the existing radio's IF circuitry and signals. The decoder board does not generate any internal RF signals to function..it relies on what is already there in the radio itself.
You can make all the radio receivers you want and not have to certify them...that is if you do not plan to market them in the US. But since this is about making and marketing radio frequency devices which convert one band over to another, it will use and generate RF energy within thus will be subject to certification.
RFB
Every time I tried to contact that place I never get a response...as if they dont even exist or care about potential new customers.
That particular receiver, including the previous model, used the Motorola C-QUAM decoder chip which has all of the IF circuitry within it. Even at that, these receivers most likely retain their specs in as far as Part 15 is concerned simply because of the use of the Motorola chip.
But let's also consider that this fella is doing things outside of the law too..and technically he is if those things don't meet the Part 15 receiver specifications.
Just because there is one lone wolf out there who may be getting away with it..does not mean our idea of marketing converters will.
Besides all that..I would not want to get involved with something that tries to work out of sight..out of mind of the law. I would want the effort to be legit and fully compliant so as to not bring out hidden problems down the road and ruin everything.
There is a reason why C.Cuff stopped making those receivers and transmitters...this Meduci guy might want to research a bit more and find out why.
RFB
chris said people lost interest in his transmitters and receivers so he got out of it. i feel if they were pll and not crystal controlled he would still be selling them. the apsisys guy is tx's are pll and 100mw and he has a pro line too that is designed for commercial or carrier current service.
- "All other receivers subject to part 15...Declaration of Conformity or Certification."
I do not see any Declaration of Conformity or Certification on the Meduci web site for those receivers.
RFB
I was told there were deeper and more threatening reasons than lack of interest for quitting.
In any case, I agree..the TX's were crystal and took quite a bit of modifying to go PLL. But the alternative was to use the programmable oscillator modules which work very well, and cheaper than the crystals.
The APS unit comes in two flavors...the 100mW and 400mW European version. I have the 400mW version driving my LPB's as the 100mW version cannot push the LPB's amplifiers enough for a full range in the LPB amplifiers capability.
The Pro line uses the same ASMAX 1 400mW exciter board. The new 100W C-QUAM unit is the one I am keeping my eye on because there is a good chance I may be able to "save" one of those Mt. Rushmore stations (KVOC AM 1230) from the abyss of darkness and return to the air in glorious C-QUAM..though the current TX in the falling apart building is a BE-1 1Kw C-QUAM TX. It's been exposed to leaks and temperature extremes and stressed to all heck and back due to lack of proper tower maintenance and got spiked left and right with high antenna currents and static discharges..not to mention the very high VSWR on the whole mess.
RFB
if the BE heads to the dumpster let me know. i now have a storage unit near me to move my electronics to and i would give you the cost of shipping if you were to salvage the modules and rf parts before it got scrapped and ups them to me.
Please sign me up for kc8gpd's idea of an extension of the extended band up above 1700kHz.
Why not the type of "converters" used for mp3 players which transmit to an FM frequency?
Our special ExEx Converter could have a tuning scale for the upper upper frequencies, and send a part 15 signal on both AM and FM to the car radio.
As an option for purists, it could ALSO be connected right into the auto antenna system.
The Swiss Army Knife of Part 15!
PLUS 1710kHz already comes in on AM radios.
PLUS PLUS many shortwave radios are being manufactured today, and they HAVE the now empty and unused frequencies above 1700kHz.
We have found our own private country on the dial and we can become a sovereign radio state with our own ambassador, which might be RFB, or it could be kc8gpd.... well, there are other titles to hand out... secretary of state, diplomat, pick one and it's yours.
