Wow! I never knew the bird was a DMM!
You can put down the Bird43 all you want, but check nearly every
professional radio shop and every prof tech's tool bag and likely you
will find a Bird. They work well and are quite durable riding in

You can always use an A range Bird slug (25 to 60 MHz) on the upper end of the
HF spectrum.
It'll be accurate on 10 & 12 M and probably not too far off a little lower, but
certainly not on 80 or 40 M.

When taking reflected power readings the slug should be 1/10 of the
forward slug value when testing a reasonably good antenna. So, a 100
watt forward slug would require a 10 watt reverse slug for reasonable
accuracy.
Unfortunately, the smallest HF slug Bird make is 25 Watts. That means
any SW
I spoke to someone at Bird (when they were really Bird) years ago and I
was told that the Bird wattmeter is accurate to ±5% of top scale. This
means that a 100 watt slug can be off ±5 watts _anywhere_ on the meter.
So, a transmitter emitting 50 watts out, using the Bird and a 100 watt
slug, c

That is 5% of full scale with a recently calibrated slug.
Another way to look at that percentage of full scale is to consider a

As long as one keeps in mind that Bird's reputatiom for accuracy has become
