A86: Re: Re: Re: Radio Link problem solved
Why don't you just hook up a CB power box to the
link... That ought to boost the range just a tad....
^_^
Wow that was fast =). I
want to build that right now! You say you got the
tranceivers at
radio shack? I couldn't find anything like that last time I
was
there. Perhaps I have to order it from their catalog. How much
did
this cost in total? And probably something everyone wants to
know: how can
we increase the range? Although covering your school
with repeaters would
be kinda fun. =)
