For ~$40  35%  [ 8 ]
For ~$20  13%  [ 3 ]
Maybe...  13%  [ 3 ]

Cool.

Might be a future project, but I see more of a need for at-least an "entry" level kit; I'm not so skilled with the Pi and a Pi-integrated unit would probably be fairly expensive. However, I do like the idea of a TV-Broadcasting Part-15 Pi..


Might be something worth getting with someone who really knows the pi to help you do something like that. Such as you supply said person the necessary functions the pi needs to do along with the basic transmitter schematic, said person replies back with a schematic showing all that is added to work with the pi along with the board layout, size ETC... then you have the boards made and said person sends you the software to be loaded on the pi. You then sell the board kit with software and the user buys the pi themselves and puts it all together for a lower price. Or for a higher price said person supplies the pi with case and all that is necessary to use the pi with the software installed to you and you sell them both together.

Reading more up on FCC regs. things are looking kinda dim. See https://emcfastpass.com/fcc-rules-kits-subassemblies/

Do you guy think if I marketed the board + base with maybe a few components pre-attached it would count as a subsystem?

IIRC, my SSTrans 3000 came with a Surface Mount IC already soldered in place. I guess the 64 dollar question is, what would be the limit? Are there any components in your circuit that would require professional installation, or specialized equipment?

No, unless your soldering iron sucks and you end up melting a plastic part before the solder :P

The best part is the inconsistency in the rules, which is always nice when a huge fine is a possibility, see https://www.sparkfun.com/tutorials/398

Further reading is required...

Alas, I think I found a concrete answer. See https://apps.fcc.gov/oetcf/kdb/forms/FTSSearchResultPage.cfm?id=20992&switch=P

Sadly, this means no kit selling for me (at least, legally). Still tempted to produce 'em, but I'm not taking the (granted, relatively slight) chance of being fined an ungodly amount of cash, just yet.

I may just provide the antenna, base and PCB as it'd be fairly difficult to call it a kit. I'll also provide a schematic, "suggested" BOM, etc. with the whole thing, so it'd probably be worth your money. Base and all would only be ~$15 at most.

Suggestions would be greatly appreciated.

Well it's awfully strange then, that the SSTrans 3000 & 5000 kits were sold for years with no apparent repercussions from the feds.

The way around this is to have it sold by and sent from an address outside the U.S., in a territory not beholding to U.S. law. I used to get pirate chips to unlock scrambled satellite channels from a guy in the Turks and Caicos Islands, as one example.

If it was actually illegal to sell kits given the date then all AM transmitter kits at that time would have been removed from the market and those of us here who have provided transmitter kits would have ceased to do so and surely some forum member here would have brought it up long before now.

It could also just be the fact that no FCC agent is going to be stalking eBay for non-compliant kits :P

Also, a good portion of kits are sold from outside the US, so they don't follow the same restrictions.

Just saying though, if someone reported (if that's even possible) my kit to the FCC I'd have to pay quite the hefty fine, and I'd prefer not to do that

I've arranged a list of possible options to this whole FCC regulation problem.
Some I definitely prefer to others, but I'll follow the forum's opinion on this
matter.

Option A:

Sell the base, PCB, antenna, etc. without electronics; can't really call it
a kit (hence little to no risk of a fine), but also kinda adds an
inconvenience to the user.

Would cost ~$15-$25

Option B:

Sell the kit illegally, not a very high risk of getting fined, but it is
definitely a possibility. Easier for user to assemble.

Would cost ~$40-$45

Option C:

Sell the completed kit illegally, presents a pretty decent risk of getting
fined, but the user can essentially take it straight out of the box and use
it.

Would cost ~$40-$45

Option D:

Work out a deal with a company like iA.M. radio so I can get it FCC
certified. No risk of getting fined, but could raise the price of the unit
by a bit.

Would probably cost ~$50-$80, depending on various factors.

Option E:

Just update schematics, PCBs and BOM readly and openly, relying entirely on
donations. May be the best option, but it's also the hardest on the user

Doesn't inherently cost anything, but donations would be greately apprecated


I'd like everyone's thoughts on these options.

If it were illegal, the forum members here who have supplied kits wouldn't have done so and it would be against the forum rules to talk about selling kits.

As long as you included a parts list, this might be the best way to go. I think it follows what Bill Hamre did with the tube transmitter parts kits.

I agree. You could maybe have a BOM with digi-key or Mouser or whomever that could be ordered in one click instead of having to look up and add each part to a cart manually. As long as there is no surface mount, I don't mind doing SM parts myself but I think it would limit the market.

As I recall Bill included all the necessary parts with his kits at least he did with the two tube 6GY6 transmitter when he was selling those kits and I'm sure I've seen him include the parts with other kits.

If a kit -in however fashion AFA parts included goes- was just advertised on this site and nowhere else, I can't really see any danger of the FCC getting involved. Bill obviously got away with it.

But it would have been illegal and we all know the rules here concerning illegal stuff. Plus I doubt Bill would knowingly do something illegal.

Option A:

Sell the base, PCB, antenna, etc. without electronics for $20.
----------------------------------------------------------------------------------------------

Then sell all the rest of the parts and electronics in a plastic bag for another $20.

It wouldn't be a kit that way.
