Thierry:

I've got one of the Autek WM1 units, and it has a switch on the front that
allows you to select 20, 200 or 2000 watts for the range displayed. According
to their ad, the meter is protected from slamming against the right side of the
range in case you have selected too low of a range. I typically use it with an
Ameritron 811H, which puts out 600 to 800 watts on a good day and the WM1 seems
to work just fine...

I prefer a separate meter for SWR and Power like the WM1 has, because I really
don't like the crossed needle approach. With separate meters, a glance will
tell you whether things are OK, while you need to interpret the display of a
cross needle unit.

Thanks

Hi OM's,

I would like to buy an external wattmeter able, in the future, to check the
power emitted by a 1-2 km Amplifier (kenwood TL 922 or another high-end).
There are a lot of models, from the portable Bird43 using a single niddle to
the MJF 817 and alike using a dual system, crossed niddles, or even digital,
but it must first be able to support a PEP of 2 kW.

As a dual system similar to the MJF model, there is the vectronic,
http://www.vectronics.com/vectronics...p?prodid=PM-30 (3 kW)
Another good one seems to be the ameritron 30X
http://www.ameritron.com/ameritron/p...?prodid=AWM-30 (2 kW)
but in both models the scale seems too small and not easy to read.
The Autek looks fine too but it is not powerful enough,

What are good models able to meet my specs ?

Thanks in advance

A SignalCrafters Model 30 is a good one with very nice meters and peak
reading, trouble is they don't make them anymore I don't think. Another
one is the NyeViking RF-3000 peak reading with a swr lockout for the
amp, again I'm not sure if they are still produced.

Bird 43 works, as does a Telewave. Diawa makes a few. It all depends on use
and accuracy required. I didn't see the original post of this to know the
intended use.

I have a Bird 43, which works fine, but is inconvenient to use, if you
want to compute SWR. You have to go to the instruction booklet and lay
down pieces of paper on a nomograph, which is a hassle.

Most of the time, I just use the cross-needle meter on my MFJ-989C
tuner. It shows watts out at a glance -- just look at the "forward"
needle. And so long as the "reverse" needle is not moving, I know the
SWR is okay. I'd imagine any of the MFJ stand-alone SWR meters would
work equally well. Just choose one for the appropriate power.

The MFJ meter is only about 2.5" wide, but is quite easy to read.
