Some thoughts:
1. The wider the range possible, the wider the receiver front end has to
be and the wider the transmitter final amplifier has to be. This means
the greater the possibility of interference issues. So you really want
to avoid having to use stuff with too wide a range.

Ok understood


2. You need to stop buying things randomly. When you buy new mikes, you
need to order the range you want. You need to sit down, list out
everything you have right now, and use the calculator on the Sennheiser
website (or a desk calculator) and calculate out all the second and
third order intercepts so you know what frequencies you can use and
which ones you cannot.

I agree, am working with their sound crew on this note (organisation)
What do you mean by 2nd and 3rd order intercepts?


3. If you do not have a plan for frequency allocation, and you do not follow
that plan, disaster will eventually result.

Ok, makes sense..thanks
