RANGEMASTER GPS RF SYNCHRONIZATION UNIT
Was on rangemaster web site, they are now shipping there gps sync. unit. I know it synchronizes remote transmitters, which is great but does it do anythin else? 😕 I have several locations that would be good for remote units but all these locations are over a mile from where the studio is going to be. How is the best way to get your programming to each transmitter? If this gps unit would also do that it would be well worth the $700 for each transmitter plus $150 for a programming module. 😀 Thanks guys this web site is great, Dan (sticklizard)

Have you looked into the 2.4 GHz STL setups?
I had Keith Hamilton look at info about it and he said that the transmitters could somehow be fed via the video port on the STL link, and in that case the GPS units would not be needed. He would need to make some modifications for you–but would not cost as much as GPS.

But I’ll explain what I know. The STL (studio transmitter link–I think that’s what it stands for) equipment can send a signal over a different spectrum. In this case it is unlicenses and I think part of the Part 15 rules.
So you could set up one of these transmitters at one location, rigged with an omnidirectional antenna, and I belive your range could be about three miles or more.
Then you could set up Hamilton transmitters throughout the footprint of your STL transmitter and rig them with receivers, and cover a large area.
I have not actually done this yet–only have discussed it with others. You might want to contact Keith Hamilton at Hamilton transmitters for additional information. He is very helpful.
Here’s a link to the STL equipment:

If anyone know of better or cheaper equipment, please let me know.
Total posts : 45366I know of some that are being made based on this:

It’s a half watt tx, and given a 79.00 omni-directional 11db gain antenna, you’ll get erp of 5 watts.
We’re about to plug these in and use them for Manteca Community Radio after the initial testing at Stanford goes.
I can keep folks informed here – they will certainly be less expensive than the alternatives I’ve seen.
Also, there may be some AM Radios coming up – we need to check into some applicable FCC rules first.. but these radios may have the recievers built into them for sync’ing.
Total posts : 45366Thanks for the replies 😀 . mlr, when you say radios do you mean the transmitters or the receivers? This 2.4 GHZ STL, sounds like computer type stuff. If it is I have a nephue that is a computer tech at a large corporation, he might could help us. I will give him a call . I sure would like to have several transmitters spread out. I am in Oklahoma and when you get away from the small town of Harrah, the houses are spread out. thanks again, Dan 🙂

Are the units you’ll be using less expensive than the ones I linked to?
I cannot find any pricing on those at active robots.
Total posts : 45366I think I will buy the rangemaster outdoor units. Everyone seems to think they perform the best. As to linking them togeather I don’t know what the expense will be. If linked by telephone do you have to have a dedicated line at each location? I am still learning about all this stuff. This STL may be the way to go. I am sure we will work it out. Some day my station will be up and running 8O. Thanks again guys 😀 Dan
