Lol yea lots of things to push. I would like the 2970 next but would need to
sell a few other things first. Are these variable wattage and what, if they
are, do they start from? Id hate to upset the neighbours with TVI )

OK, I designed and build a new Watt meter today, thsi is the BIGGEST watt
meter you can imagine, once got this thing from a lot of stuff that was to be
thrown away.
What I actually do is a peak detection of the RF output at the antenna,
and then used the calculator and dummy load a lot...
Calibrated with comparing with an other known set, diguital meter and scope,
should be within 5% or so...
Because this meter had a different scale I wrote the new values in it
(it is so big hehe).
Here is what I have measured:
FM
RF gain Watts
minimum 2W
button pointing left 10W
button pointing up 27.5W
button pointing right 30W
maximum 35W

AM is the same, is SSB with mike gain to max and blowing in the mike
and RF gain to max: 144 or more watt (end meter scale).

So, I think with 2W minimum on FM and AM you will be fine.
