Starting up 2 LPAMs and looking for equip you might no longer need. Email....... [email protected]
Thanks....
I have some parts for LPAM, including a brand new loading coil for the SSTRAN AMT3000. Where are you located?
we're in Texas, might could use the AMT3000 but we're not FCC approved so the SSTRAN would be out. Sorry.
ACK!!! There is no such thing as LPAM!!!! There are only part15 or fully licensed stations on AM,this includes TIS. The SStran is part15 legal since it is 100 mw output so you dont need a license. The Rangemaster or Procaster would also fit the bill. You should read these forums a little closer to get the "big picture" and know what you want to do. There are folks here willing to help,but I dont understand why they didnt set you straight here,so I did. Good luck in Texas!
Not sure what you're asking. The only legitimate LPAM devices you can operate in the U.S. at this time must come under FCC Part 15 regulations. In the case of all the midband AM transmitters you see around this forum, including the SStran AMT3000 model, it means they have a maximum output to the final stage of 100mw, i.e. one-tenth watt.
Therefore LPAM at this time is nothing at all like LPFM. LPFM requires a license, Part 15 operations don't.
Here's what I know from talking with owners and research:
LPFM Community Radio stations are a legitimate FM band broadcast format except that although not full power, they can have up to 100 watts max (that's 1000 times more power than a Part 15 transmitter), cannot be owned or operated by an individual, and the ownership must also be a legal Non Profit Organization of some type (Board of Directors, Board of Trustees, etc.), plus, they must not cause interference with full power stations. The FCC created this new form of community radio in January of 2000. Such organizations can only apply for a Construction Permit when the FCC opens a window to do so.
Involves a lot of engineering and compliance with regs as well. The organization in my area has spent several years on the project, finally got their Construction Permit last February. They have 36 months to actually build the station to specs and get it licensed, or they could lose it and have to start over. That includes at least 6 hours/day of locally produced programming (but not necessarily local content) as well.
The FCC does allow a testing stage before issuing a license, meaning an LPFM station can operate under their Construction Permit for a limited time while gathering the physical data to send in for their final license. A nearby station used that time to get programmers to produce shows as well.
Before I joined this group, there was a movement to write proposed legislation for the same sort of station ops for LPAM, but it failed. At the moment, all we have in the U.S. for AM radio is either Part 15 or full power commercial stations. Nothing for community radio in between.
You can buy a midband AM transmitter which is more than 100 milliwatts ... you just can't operate it that way legally without a full power commercial license.
