I know that the syncing of transmitters is not ideal. My point is that, considering this is the only way we Part 15’ers have of covering a larger area, it an option worth having.
As for using multiple frequencies, yes, that can be done. However, expecting listeners to keep track of which frequency you are on in various parts of town is asking a lot. Rememeber, if we make it difficult for them to find us, many won’t bother. Also, having one frequency makes the station appear more professional and is less of a logistical problem. And what about people in their vehicle? Forget it.
As for internet vs STL feeds, I’m not saying that both can’t be used. Whaterver suits a particular installation. Don’t limit our choices to just one. No one is saying that you have to provide the STL equipment. In fact, your transmitter shouldn’t care where the audio comes from, so this should be a non-issue.
As for syncing carriers, that is a separate issue from the audio and is not necessarily an STL specific issue. As long as the sync signal gets to the transmitter, it doesn’t matter how it got there, although I will admit that it will most likely arrive via an STL type setup.
The comments about syncing multiple transmitters as being “less than desirable” are certainly true. However, what other choice do we have if we want to cover a larger area with a single frequency? We either use multiple transmitters that are synced or not synced. The synced option is the better choice of the two. If anyone has a better idea, I’m sure everyone here would love to hear it.
I’m not trying to knock your kit or your ideas. I’m just hoping you’ll be able to provide an alternative to the Rangemaster, at a more affordable price. In my view, the Rangemaster has only two things going for it. One, it is type certified. This is certainly desirable, but not required in many situations. Two, it has the syncing option. As far as I know, it is the only unit that has this capability. Personally, I think that the sync option is his biggest selling point. Look at that station south of Atlanta (mentioned here recently) that is using 11 Rangemasters. In fact, every story I read about someone using multiple transmitters mentions the Rangemaster. I don’t think the type certification is the only reason.
If (and when) LPAM becomes a reality, then that may be an option for us. If it isn’t screwed up like LPFM, if it doesn’t cost an arm and a leg to get a license, if you can even get a license, etc. Even then, Part 15 will still be the way to go for many people.
My two cents worth about the stereo suggestion – I’m sure it sounds nice, but how many of our listeners actually have an AM stereo receiver? I would guess almost none. I actually do have a SW receiver that can decode AM stereo on the BC band and I wouldn’t care about a stereo transmitter.
From your previous comments, you obviously have at least built a prototype unit. Do you have any pictures? I’m sure we’d all like to see them.
