Cuthbert AM Stereo C-Quam Transmitter Kit! Finally!!!!!
« on: June 02, 2018, 1536 UTC »
Yeah!!!!! Finally!!! A Part #15 AM Stereo C-QUAM kit!      https://radiojayallen.com/cuthbert-am-stereo-c-quam-transmitter/    Question is, will this be a come 'n go sort of thing, or will it be a neat Part #15 buzz that can help give LPAM and C-QUAM stereo a kick where it needs it? Time will tell. The sad part is that it may end up being that there will be more AM stereo transmitters than receivers out there. However, there are kits out there for converting you favorite stereo tuner, or receiver, to have C-QUAM ability, like this site,     http://meduci.com/

It'd be nice if the sdr app makers would add am stereo to their repertoire.

Yeah, no kidding! Just how hard would it be to write up software for SDR's to be able to have C-QUAM capabilities? I am the last person to know this since I almost failed out of computer electronics in college, since I hated machine language.

Good to know about the SdrDx! Hmmmmmmm, Radio Jay didn't mention the actual ebay site for the Cuthbert C-QUAM TX kit, so here that is,      https://www.ebay.com/itm/AM-Stereo-C-QUAM-Transmitter-Kit/132644744317?hash=item1ee23e2c7d:g:U5gAAOSwIgNXoPEJ      and the quick demo Youtube VID,     https://www.youtube.com/watch?v=NEDBxmDJYwo&t=6s       Neat item, but it is nice to know where to get it. Just my $0.02 worth.

Why's is it on VEROBOARD?

Why not on a PCB?

so does SodiraSDR which i prefer since it has many adjustment capabilities for the advanced user, it also has DRM decoding.

Yes, I was thinking the same thing. $169 and its on prototyping board, not a proper PCB? You have got to be kidding me.

Eh, who knows??? Maybe he's gotten veroboard boards for a dime a dozen. I can't bitch, I've built my 22M mW transmitter on one as well. Certainly doable. Still, the kit is under $200.00, so Cuthbert's broken that ceiling barrier for a kit like this. I seem to recall paying almost that much for a Panaxis AM-100 100mW mono exciter kit back in 1991. (I still have that.)

PCBs are $1 sq inch double sided from OSHPARK in quantity and even if that's too expensive, China will probably do it for much less.

There's some no excuse using Vero for anything these days, it's crap and always has been, even smells funny, never a good sign!

Seriously tho' ANY kit should be on a PCB.

Maybe the 'Designer' has never laid out one before?

Time to learn I think...

Well done on the price, if that's what you want.

No need for anything like this other than US??

Stereo on SW?....Hmmm......

Awesome, already got sodira installed. However, it's a huge cpu hog, wonder what's going on there.

DRM is dead. What is needed is an open source digital format for MW and SW.
As for part 15 AM don't you need to put the transmitter at the junction of your ground radials and 3 meter vertical? That is "outdoors". I would not pay that kind of money then put that thing outdoors.

Ahhhhhhh, but that's where you can be creative here. My AM1620 transmitter is just mounting in the garage, on the inside "A" point of the eves. The radiating antenna is about 12 inches short of 3 Meters in length, to compensate to feeding a 12 inch #8AWG from transmitter to the actual radiator, thus making it Part #15 FCC compliant. You may have other locations that can work, like the inside / outside eves of a tool shed. Passing thought, again... Not everyone can do this, (Including me, thus why I garaged-it.), but your house attic eves can be utilized the same, if you own your own house.
