Hello Professor:

Man that meter looks Bitchen!

What they want in American money for that?

Helo Professor:

Ok good deal I looked at it at the web site.

I am sure with all the slugs for a Bird Wattmeter to cover all the
frequencies and power levels, the price would be close.

I don’t know about the 2-200MHz meter but the 25-1000MHz version is not
in the same league as a Bird 43. I have owned 3 of the 25-1000MHz
versions and two of them had an intermittent OFF-FWD-REV switch. From
about 100MHz up the meter is direct reading but below 100MHz you have to
use a % chart to figure out the exact power, which is very cumbersome. A
Bird has a well made silver plated 50ohm line section and the Telewave
has an unplated aluminum line section. The Telewave connectors are much
lower quality than Bird. The Telewave also has the lower portion of the
meter designated off limits because the accuracy is way out of spec
unless you use the upper areas of the meter scale. Used Telewave meters
usually go in the $200 to $350 range.

Mike,
I agree that meters with a "correction factor" are a pain in the ass.

I'm not quite sure what the significance of your comment about the
silver plating. Why would not having the plating on the Telewave cause
any problems?

Also... it's my opinion that the section on the Telewave meter that
shows that the user needs to change scales (to get to a higher meter
movement) is good. I have serious doubts that any of the meters (Bird
or Coaxial Dynamics) have good accuracy very low on any scale.

As for your intermittent fwd-rev switches... not sure if you bought
these meters new or they were heavily used when you experienced this
problem. In any event... the switch is probably not a very costly
item... and not too hard to replace.

The main reasons for my interest in this meter is:
Don't require DC-1GHz coverage.
Don't like goofing around and keeping track of all those slugs.

Thanks for your input!

Well... just ordered one of these and a 150W load. I'll let you know
how it is.

The Telewave meters are fine for relative radio service readings like
reflected power and relative forward power. The intermittent switch can
be replaced or treated with Caig Labs DeOxit to help that problem.

It's hard to make a non linear, broad band calibrated meter within 5%
for the price they bring it home (sell it). .

If you stayed under 500 MHz and didn't want to soak up the high cost of a
Bird and all its slugs, the meter's a good deal and a real work horse.

It's a tool and should be used as such once you get to know how well it
operates. I don't use my Bird Meters for calibrated power measurements
anyway. They're not a rocket science device... two same type slugs always
seem to read a little different.

95% of the time you're looking a relative values just related to forward
and reflected power.

OK... thanks for your feedback Skipp.
Oh, by the way I enjoyed your web site.
