I really enjoy your comments.
I think the TriSquare 900 MHz FHSS
radios were probably designed for
voice in the 300 – 3000 Hz range.
But to find out, the best thing would
probably be to call TriSquare and ask
If they were able to pass high audio
fidelity, they would be the absolutely
perfect 900 MHz STL.
Except for one thing. My solar powered
49.83 MHz (For the prototype)/88.3 MHz
repeater will require a minimum of
energy. I have almost all the parts.
The prototype is just going to run when
it’s in sunlight. But later, if I start fooling
around with charging circuits things will
be different. If the unit is going to repeat
24 hours (or even 12 or 18) it is going to
have to consume very little energy, or the
battery charge cycle will never be able to
keep up with the demand.
The TriSquare radio (from what I have read)
needs a fair amount of energy to operate.
On the other hand, the 900 MHz transmitter
and receiver modules that Neil suggested
don’t appear to need much energy (especially
So here we are. My first step is to get the
prototype working. I am buying a few parts
at a time. It will be running soon, I think.
