I've been looking for a good AM/SW Radio with a DBuV meter and super sensitive with SSB!
I don't think the C. Crane Radio has a DBuV meter. The Tecsun 310 and 380 has DBuV and super sensitive but NO SSB so I can't listen to Ham Radio wheen I get the urge to unless I use another SW Radio and Jam it by tuning around until its internal oscillator throws a dead carrier on the frequency I want to receive SSB on. I have a home brew BFO that was built for me so I can plug it into a SW receiver with that IF output which throws a dead carrier around 455 Khz Some Radioo's are 450Khz.
The engineer is on his way Today is the big day!
I've been promoting C Quam Today as Today is the day. The station is called C Quam 1700 The Legacy The Station Revitalizing AM. A list of C quam Radio's is played after every 9th song and our Rockline is posted along with AMStereo(dot)org. Some already have ordered their Radiosophy HD-100 from Ebay.
There is also the maducci decoder you have to have an entineer install inside your Radio if you can't or don't know how.
I've also promoted that other hobby stations operate on AM and may use C Quam (this too is where we will shine).
Local announcements about events is another thing I do here as well!
Last year my complex had a yard sale and I announced it. Plus events at the Sunset Grill in Deltaville, VA such as when the band Rip Tide played because they are an Album Rock/Classic Rock band. Also giving shout outs to businesses who have been in support of the station.
Buying Radio's and modifying them for C Quam for listeners will also help!
With that board costing $20 buy a listener a high sensitive Stereo boom box and then install C Quam and then charge $100 for the install. You make a little money for your station and that listener runs off and tells their friends "Listen to this" and then when his or her friend hears it on AM they too will want one and the idea spreads like a virus. Soon stations will be called with people wanting C Quam.
Separate service for Hobby Broadcasting called The AM Revitalizing Project!!
As a requirement the hobbyist must broadcast C Quam and has the same allowable power as a TIS station and the hobby broadcaster must identify their station as C Quam (frequency) followed by their brand aka C Quam 1700 The Legacy.
I don't know if HD AM would work for part 15. I've thought about that too.

The Illusion of StereoAcoustic events are all monaural in the natural world. A voice, an instrument, a bird, a dog, a car horn. Stereo is what happens in empty space between monaural sounds. Stereo is the distortion that the passage of time puts on a mono sound as it reflects and moves away from its point of origin and mixes with other monaural sounds. Lab scientists call monaural sound events "coherent sound". They call the stereo effect "incoherent sound". Monaural sound is the most focused way to listen to musical instruments (including the voice). Next question please. Yes, have you ever noticed that the original recordings from the Beatles were in mono? Look at old videos of Lennon/McCartney singing into the same mic. Then these recordings were re-channeled into stereo with music in one channel and vocals in the other. |

That video that Gerry from Chez Radio posted over at Part15.us of his Procaster playing music sounded pretty damn good to me. I think that is a better option for playing album rock and reaching a decent sized audience. I have said all the time that stereo is a recording effect and not the way you hear things normally. I grew up on and still do listen on a radio with one speaker as typical of most radios and with a good sounding one like a GE super among others there's nothing wrong with it.
All someone needs to listen to album rock is a decent sounding radio and with wide band like the Ccrane one or the Eton field radio but any will do. I personally don't like to be wired up with headphones to get the best stereo effect or sit motionless between two speakers placed just right in a room indoors. Like Tim I grew up with a regular radio but I do like nice sound and have a hard time listening to small pocket like radios with harsh tinny sound.
Agree with Tim's post.

Yesterday's C-Quam Experience in the engineer's van!
Traffic - Heaven Is In Your Mind was absolutely outstanding. I almost forgot I was listening to an otherwise social stigmatic broadcast band called AM or medium wave. I also listened to Led Zeppelin - Tangerine as well as The Moody Blues - Legend Of A Mind. WOW!!
The Landlord came running to the van to see what all the excitement was all about and we put on a C-Quam demo for her and her friends. She could not believe she was listening to AM as in her words sounds absolutely horrifying and full of static. She went to Ebay and purchased the Radiosophy boom box as we showed the link for. And Kim is looking for the Sangean because of the removable speakers.
When they asked why these Radio's were not available on the shelf I told them to make a complaint to the FCC and ask that C-Quam is mandatory in all future Stereo's with AM. So now I have two people right in my complex who DEMAND C-Quam. See I've started something and this is why the engineer is donating to my station so he can make this a mandatory requirement.
Even in Mono on my Grundig I notice A SUPER SOUND not heard from the Talking House transmitter.
Range sucked however We may go Carrier Current!!
Now onto talking to Bill Baker about a C-Quam transmitter for carrier current or some other way as we only got out 1/4 mile in C-Quam before it faded to Mono and then at 0.9 miles was unusable to most Radio's.
The Realistic was modified for 12 volts and connected to a car antenna for AM and FM. The Radio had to be modified for 1700 Khz. Receiving C quam was a breeze after that. I only wish you could have been there for this demonstration and push towards AM revitalization.
Maybe we should go to Washington him and I and start a protest march for C-Quam's return. I think public publicity could also help. Remember this will also END PIRATE RADIO and this should be the first thing on the petition to enforce C-Quam along with a separate Hobby Radio service but with the requirement of C Quam at 10 Watts.
C. Crane Radio's should be experimented with as well as Tecsun to see if at least the mono experience is better on the C-Quam transmitter. So stay tuned. We have tricks up our sleeve.

That's one problem....all radios are to be had online from Amazon(The UK site has nice radio's not available in N. America), Ebay, CCrane, etc.....Radio's are not sold in stores except for a very few(stores).
It's not like the 60s and 70s where radios of all makes were sold in all department stores...Sony, Hitachi, Panasonic, Sanyo, Channel Master, etc etc.....and many more. From entry level models to higher end ones, they are all still there but not in brick&morter stores.
As for C quam I am sorry to say that there will never be a FCC rule to mandate manufacturers to make radios to a certain standard as all the radio manufacturers are not USA based. They are Japanese(Sony, Panasonic) and British(Roberts) and Taiwan(Sangean). Others are not in the USA. Oh ya, Eton/Grundig/ which are made by Tecson is Chinese. Eton has headquarters in the USA in California I believe but the FCC will never mandate them to make receivers to a certain standard as there products are made by Tecson as I said. Even the HI FI manufacturers are not based in the USA except for a very few.

Yes!! anything that says Prime where the shipping is done from them is shipped by their global shipping service. Ebay UK site has sellers that ship anywhere. Take a look.....you can get Roberts, many Panasonic models and Sony models not available in N. America markets. I have a Panasonic from Germany on the way to me now.
Here's a brand that has been around for 80 years and never has been available here.

Sounds very promising Legacy! I wouldn't cut down the range until you do some antenna experimenting, that's always important, I can't express how important that is! I'll give you an example of my own, with the Talkin' House way back when I got it in I'm thinking 2006.
Knowing that grounding was super important on AM, I put my transmitter right at my house's power line ground stake and ran a ground lead between the two. I held up the antenna wire on some thread so it was straight up in the air. I think I used a portable radio for the audio, relaying an FM station. The range wasn't as good as I thought it would be, that was between two buildings, with the antenna about 15 feet away from mine.
I took some advice from one of the sites then and set up in a yard maybe 100 feet from any buildings, a similar setup, and the range easily doubled!
The ground was hardly anything at all, just some spikes I found in the yard, like tent spikes, and I ran clip leads to them from the transmitter's key in the back. The power was getting there through a hedge trimmer cord laying on the ground.
The piece of ground was even lower down than the buildings, and open except for a tree line in the back and a few trees scattered around the property.
If you broadcast that quarter mile from in or near a building, I'd think you were doing pretty good!
Another question I wanted to ask about the Sean Cuthbert transmitter, how do you like the auto level control circuit that's in it, how does it sound, if you had a chance to test that out.

To be clear, at least as far as radios are concerned. Sadly you cannot buy an air pistol or air rifle on ebay UK or Amazon UK. |

As my engineer friend and I we're trying to figure out why at his house he was getting better range than I was it dawned on the two of us. His antenna design was made out of aluminum and mine because they ran out of aluminum at the place he got his material from was made out of galvanized steel.
Also with the Sean Cuthbert transmitter we found that putting it closer to the antenna as he did at his house and having a short piece of wire soldered to the antenna and the other end connected to the transmitter in a waterproof box seems to make a big difference.
Either Sunday of this week or Tuesday of next week or early next week we are going to try two things. One of them is to put the transmitter in a waterproof box with long audio cable going from the computer to the transmitter as well as an extension cord for the power. Then the antenna will be made out of aluminum and not galvanized steel.
Next is to have ground radials of 100ft buried in the ground.
Knowing that the scene Cuthbert transmitter was meant to operate with a wire we find out that the less resistance you can have is the best. We tried to work with my 75 ohm cable and change that to a 50 ohm load that we thought would match the transmitter but remembering that the wire that comes with the transmitter is probably more like an 8 ohm wire or a 4 ohm wire just like speaker wire so the engineer tried something and that was to solder a very short piece of the type of wire that comes with the transmitter directly to the antenna and then tune up to it with the transmitter`s built in ATU circuit.
Just like the talking sign will do on its output the transmitter seemed to work a lot better at his house.
Also Sean Cuthbert has 3 designs and it could be that the third design is much more picky then the transmitter he has at his house which was the design before mine. We did notice a warbling effect which we had to make some adjustments to fix at my house.
We are going to try working with antenna broadcasting first before we switch to carrier current as a 100% broadcasting medium.
I am hoping to get the 1.5 to 2 mile radius that I need.
As my engineer friend says we are not giving up.

Yeah, that's a difference between the Talking House/I-AM and Sean's transmitter, the Talkin' House has both low impedance coaxial output for its remote antenna, and high impedance for a 3 meter wire, while Sean's only high impedance/3 m wire.
The Cuthbert transmitter looks like a home unit you'd sit on a shelf indoors to feed your stereo radios, as I suspect it would be a popular product among the radio collector crowd. For range and getting it outdoors, you might want to check into the method used with the latest Talking House setups that puts the TH in a weatherproof box with an external antenna mounted to the box. That way it can be placed in an area good for transmitting and power and audio run to it.
As for the guns, well it's better to try to negotiate first, I'd think.
Friday 6/8 update I recorded some AM stereo demo audio from my station on a couple of radios, and I'll be working on a results page to share soon.

AM stereo demo pageI made a web page with listening tests to show what you could get from C-QUAM AM stereo on some analog receivers. boomerthedog.com/am-stereo-is-coolLegacy pointed out some newer radios that might receive C-QUAM along with their HD, but so far I haven't heard how they'd do in real life, but I'd like to hear if others have experience with them. I might add things to the page if someone has ideas or I think of more info to put on. Boomer
