SDR Dongle says I'm getting out. And if I whistle, I can deflect the Bird meter. Thanks everyone for your help. I was worrying for nothing.

Try AM mode and the meter should register or get another meter that can measure ssb

You would have to whistle fairly loudly to get a swing on the bird

I do have a little USB SDR. I plan hook that up tonight to see if I
can see an indication of signal. I don't want to furiously try to contact someone via satellite and find out I'm not putting out any power.
I've never owned this rig until a couple days ago so there's always a
possibility I'm doing something wrong.

Peter are you speaking loudly
The energy in an fm envelope is way larger than a side band
transmission
The fact that your reaching an alc level seems to indicate the radio
is doing its job
Pity u don't have USB rx
Do you have a software defined radios ?

I bought a used IC-910H on ebay for satellite work an am having a
possible
issue with it.
I tested the 2m and 70cm transmitter and receiver in FM mode with
my
handheld and they work fine. I hooked up a Bird 43 wattmeter with
a 50E
slug (50W, 400-1000Mhz) and when I transmit on 440Mhz FM I get an indication of power output on the meter. So far so good...
Then in USB/LSB mode however, I get no indication on the meter,
despite
turning the mic gain up and talking into the mic. I've also up'ed
the RF
power with the little knob and that doesn't help. The red light
flashes on
the rig (ALC indication) and the meter on the rig moves. I can
also hear
distorted audio on my FM handheld (as expected since it's FM and
not USB)
but I'm worried about the lack of power indicated on the Bird. I
haven't
been able to try CW yet because I don't have the right sized plug.
Should I
be concerned about the lack of power?
Summary: Bird wattmeter shows power out on FM, but not on
USB/LSB.
Thanks

If your rig has a RTTY mode, switch to that and key down. You should get a full power tone with no actual data modulating it.
