Sorry to ask this question, But is there a combo am transmitter, with a ant, that does not require all the ground coils, and tuning? I was just wondering,
want to have a LPAM station to complement my part 15 fm, and just didnt want the hassle of tuning a ant... Please Help Me? Thanx.<P ID="signature">______________

But wouldn't you want to stay within your proper frequency and maximize your range?<P ID="signature">______________

The Talking House II has a Auto Tuner and is PLL Synthesized. Heard with a good ground it will do 3000ft to a Car Stereo. one could take it out of it's box and put it in a NEMA enclosure and attach a 1" O.D. 10ft Copper Pipe in place of the wire and have a decent Tx, but the audio on these are a max of 6khz.

Arent most Licensed stations running on about 6khz these days anyway.

Mostly just the ones running IBOC, such as Clear Channel & Infinity. Lots of other stations are still transmitting full fidelity NRSC.

I wonder if there is a cap in the Talking House somewhere which is used to restrict the response to 6 kHz. Find the cap and either eliminate it or reduce its value to open up the frequency response. This assumes the thing is not so narrowly tuned that the upper audio frequencies are greatly attenuated.
 
If a Part 15 AM station using an SSTRAN gets visited by the FCC, the operator will be in trouble because the SSTRAN, as nice as it is, isn't FCC-certified. The Talking House www.talkinghouse.com , TalkingSign www.talkingsign.com , and RangeMaster are FCC-certified and legal.

The Talking House and TalkingSign can be mounted outdoors in a weatherproof enclosure with their 3 meter wire antennas inside a white schedule-40 PVC pipe. Or, they can be used indoors with their outdoor antenna tuning units and 102" CB whip antennas mounted on non-metallic poles. -- J. Jason Wentworth

The SSTRAN is a legal transmitter as stated in the Part15 rules and this discussion of whether this or any Part15 transmitter that complies with the Part15 rules whether a kit or not! Please read the previous threads on legality of this issue... go back perhaps 5-6 pages to read about it.

Re: No Jason, it is legal.

I have read the FCC Part 15 rules on the FCC web site, and kits are specifically excluded. Type-accepted or certified (by an FCC-approved laboratory) or completely home-built (non-kit) transmitters are permitted, although any builder had better be prepared to prove (with sophisticated test equipment that most Part 15 station operators don't have) that his/her transmitter meets the specifications if an FCC agent pays a visit.

Carl, why don't you submit the SSTRAN transmitter and antenna to an FCC-approved laboratory and get it FCC-certified? I won't use any Part 15 AM or Part 15 FM transmitter for continuous broadcasting unless it is FCC type-accepted or FCC-certified as being legal for use. It won't prevent an FCC visit, but the field agents will cut a station operator much more slack if the transmitter is FCC type-accepted or FCC-certified. -- Jason

Re: No Jason, it is legal.

The SSTRAN is not the "same basic unit" as the RangeMaster--it is essentially a clone of the British-made Metzo (or vice versa).

If FCC type-acceptance and FCC-certification for Part 15 AM transmitters wasn't important, then the manufacturers of the Talking House, TalkingSign, RangeMaster, and LPB AM1000 wouldn't have gone to the trouble and considerable expense of having their transmitters evaluated for FCC type-acceptance or FCC-certification. To the users of the SSTRAN and other non-certified transmitters I say, "Broadcast at your own risk, and take care not to get caught." -- J. Jason Wentworth

Please be careful about spreading opinion vs. fact. The certified transmitters mentioned are certified (and are required to be certified) because they are fully manufactured units. Kits do not need to be certified. All Part 15 transmitters must comply with the rules to be used legally.

Re: No Jason, Phil B is right SSTRAN kits are legal

Hobbytron did not get busted for selling Ramsey kits, Hobbytron got busted for selling ready to go Ramsey 25B & 100B transmitter.
Here is the PDF document from the FCC
http://hraunfoss.fcc.gov/edocs_public/attachmatch/DA-05-2382A1.pdf
I think it's BS what the FCC is doing to Hobbytron and others. Its more proof the goverment is out of control.
Many of those selling turnkey Ramsey transmitters on e-Bay have been busted or had an intimidating letter sent to them.
I have a great ideal! lets have Congress cut the FCC budget to next to nothing and send it to Katrina victims. Now that would be serving in the public interest.

Indeed; the public interest involves rebuilding private property for uninsured morons who demand cash from people who don't even own their own home.

But that wouldn't be radio related.
 
Re: No Jason, Phil B is right SSTRAN kits are legal

I have seen ready-built SSTRAN transmitters illegally for sale online.

A while back I called the Anchorage FCC office regarding the kits vs. scratch-built vs. ready-made transmitter issue. I was told that kits are illegal--period--and that if I used a scratch-built transmitter I'd better have a calibrated Field Strength Meter and oscilloscope handy to prove that its output power and harmonic suppression are within the Part 15 limits. When people like that could shut me down and cost me lots of money, why should I risk trouble when legal transmitters are available? -- Jason

Re: No Jason, Phil B is right SSTRAN kits are legal

I too have seen ready built Sstran transmitters and others for sale myself and I know those who do. I see nothing wrong with it as it helps get completed transmitters in the hands of those wishing to serve their local communities.

If you ask 10 IRS or FCC agents a question you will get 10 different answers.
Just as you can ask 10 cops a question about how fast you can drive before he will pull you over? You will get 10 different answers.

The real question is what is reasonable. At some point the FCC is going to have to deal with the public, The FCC is already stretching it with the public controlling what they can see and when we can see it on satellite and cable television. If the FCC starts busting every part 15 broadcaster who is slightly over power the FCC is going to hear a public out cry loud and clear. The only way the FCC gets any public sympathy is though bold face lies and disinformation, As community broadcasters we must educate the general public about where the FCC interest lies and that is protecting big greedy corporate broadcasters though the N.A.B..

The FCC could careless about interference caused to ones television or radio and has pretty much said so.

I myself think its past time for some rules changes at the FCC, The only way that's going to happen is though public pressure.

Yeah, I thought the FCC was understaffed and underbudgeted. If they can get their shorts in a twist over Hobbytron selling two pre-built micro power transmitters which are not FCC certified, then they've got way too much time on their hands. The people investigating them must be the same people who were doing all that hand-wringing over Janet Jackson's left breast (or was it her right?).

To be sure, there are some very serious issues and breaches of trust regarding the governance of the FM/AM bands that need to be addressed (most as a result of the FCC and the power Congress has given the agency) but this isn't one of them.

Of course, the investigation started out with Hobbytron selling Veronica equipment. And as was reported (and I think it was Steve at Radiobrandy who pointed this out), their equipment is not that well made. So, it may be to every brodcaster's benefit if Hobbytron were forced to stop carrying Veronica's transmitters and amplifiers.

But it's obvious from the wording of the FCC Notice that pre-built "radio frequency devices" that are not certified by the agency are not to be sold ("leased, advertised, shipped, imported") in the U.S. Of course, a kit, that is to say a box of parts with a sheet of instructions, is not a radio frequency device. Neither is a partially-built transmitter a radio frequency device. It's still just a box of parts.

So it may be that Hobbytron (and for that matter Ramsey too) will have to either just sell kits or partially-built kits with the purchaser doing some final assembly. It would also seem legal for independent builders to offer to build these kits for a small fee for those purchasers who didn't want to build their own transmitters.
