I know I have asked this before. But, now I have more details.
I have an alert signal (motion-alert from dakotaalert.com, with about a 5second-long
alert message) automatically going into a Baofeng uv-R5 (call this radio #1). I have a maze of very tall obstacles that I must communicate
through/around. I cannot make a tower tall enough that I will get line-of-sight (LOS) --- not
going to happen in my application. I have 20+ feet tall mounds of dirt all over but I do have passageways in between these mounds of dirt
(like a mouse traveling through a maze if that is a useful analogy).
Now, what I am imagining in my head is this: I am going to manually set "communicators" (whose details I am asking your help on)
along a sequence of physical locations, A, B, C, D, E, F, G. A has LOS to B. B has LOS to C. C has LOS to D. D has LOS to E.
E has LOS to F. F has LOS to G. (I am located at G and I want to hear the alert at A from radio #1).
Radio #1 above communicates to "something" at B. B sends it to C. C sends it to D. E send it to F. F sends it to G.
Again I am at G and want to hear the alert.)
What I wish to know is what equipment is needed to accomplish the above task.
This is not a traditional repeater situation where you put a huge tower on the top of some mountain; that is
not going to happen in my application.
One suggestion that has come up is simplex-repeaters (presumably six of them for the above A-G setup). My nominal concern with that is this: The message gets
'repeated' about 6 times, 5seconds being the length of the message, for a total of 30seconds of delay. In my application I can only tolerate about 15seconds worth of delay, absolute maximum; so, 30seconds would be too much. Maybe simplexes could work out if the message-length can be cropped by the simplex-repeater down to about 1.5seconds. 6*1.5seconds = 9seconds, which is a delay-size (9sec) that my application can tolerate.
Great thanks in advance for all the help.
Again the end goal is to hear the alert. I know some will ask why not put a huge set of speakers at location A. One reason
that would not work out is that it would "SCARE" the person who has tripped the alert in the first place. I am not trying to scare;
I am just trying to be alerted/informed.
(Going on a month now trying to get this solved).
