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

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 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.

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.

Peter,
The IC-910H is a great radio...but it has a reputation for being picky about any DC voltage drop from the power supply / power cable when you're attempting to achieve rated power output.
Until you've achieved the results you'd expect, I'd make sure that you have a stout 20 amp power supply that maintains 13.8v at full load, and that your power cable connects directly to the power supply. If you've got any power cable extensions, power pole distribution blocks, or extra connectors in line with the power cable, they may add some resistance which can impact the transmit power output on the radio. There may be no impact, best to make sure if you're not satisfied with the transmitter performance.
Use a dummy load in your testing to ensure that the transmitter has a 50 ohm load and the transmitter protection isn't reducing power if the connected antenna isn't a perfect match (which few are).
The Bird is an averaging meter, and SSB is low in average power output (unless the audio is compressed) so, you're not going to see a lot of power in SSB on that meter. Thats the reality measurement.
While the transmit audio quality isn't what I prefer when used, you can enable the 'Comp' which is the compressor, which will increase the average transmit power which will produce a higher average reading on the Bird meter. Doubtful you'll want to use that feature in your on air pursuits in the long run, but, may offer insight in your testing.
As for CW, you can find in the manual how to enable the up/down buttons on the microphone to be the keyer in CW mode.
If you want to hear your 145.000 Mhz transmit, connect VHF to a dummy load, tune to VHF to 145.000 tune UHF to 435.000 set both to USB, Transmit on 145 Mhz and you should hear the 3rd harmonic just fine and get an idea of your transmit audio.
HOPEFULLY you'll conclude that you've got 10-15 watts average saying FIIIIVVVVEEE slowly on SSB into a dummy load, and conclude things are reasonably good and we'll find you on the air soon.
Hope this helps, Mike W4UOO
