Hi Neil! Thanks for the info on how you dealt
with the 900 MHz chips that you had. I think
it is very cool.
My projects go very slowly because of my life
situations. But I can tell you that I almost
have everything I need to get this solar powered
repeater up and running. (With the 49 MHz feed.)
When the time comes, I will try to do 900 MHz with
those new chips from the same company.
By the way, I looked up 900 MHz walkie talkies and
found a remarkable (at least I think it is) product.
I think the company is called TriSquare. (I’ll have
to check that.) Anyway, they make a pair of
walkie talkies at 900 MHz that do frequency hopping
spread spectrum. This means the transmission
cannot be monitored on an analog receiver. I can’t
remember if they change channels 50 times a second
or 500 times. The range is said to be better than
that of FRS radios. I read some reviews. One user
said that if you were using more than two radios
for the same conversations, there were some
sync problems. But these radios are inexpensive.
Depending on where you order them, it looks like
you can get a pair for about $70! If I was made
of money, I would buy some tomorrow just to
see what they were like. If I thought they could
be hacked easily, I would buy a pair for my Part 15
Anyhow, they were interesting. Thanks again for
your 900 MHz application info, and I will keep you
and the whole crew posted as to where this
