Nice product, but a little pricy.
I'm also looking for affordable solutions, but which are legal to use here
in the UK.
I'm looking for a range of 700m-1km line of sight outdoors with an
over the air data rate of about 9600bps and I don't mind trading off
having to write software to drive it in exchange for a cheaper product.
(This is for a hobby project, so cost matters, but I don't mind spending
the time to write software to drive a cheaper product.)
What I don't want to do is to have to design a PCB around something
like the RF Solutions T7 modules (I really don't want to have to get into
designing and producing PCBs), but I would be interested in hearing about
anyone selling completed circuits for example.
I am open to all affordable ideas for a 700m-1km/9600bps range, regardless
of specific technology.
Thanks for any information,

You need to view all these answers in the light of most transmission
ranges are given in terms of up to X, which means in any or more likely
most conditions the range of effective transmission will be
considerably less than X. In some common cases the transmission range
may not be any where close to X, even for spotly transmissions. It all
depends on your application, and how many messages you can lose, and
whether your 2000ft figure is the real minimum or has engineering
margin in it. In any case you need to be pre-pared to handle dropped
messages in most transmission methods that get through what ever
retransmission method the communication medium uses. Even in wired
buses of reasonably short lenght, messages get dropped.
