Missing a zero on weight.

If you consider what actually happens to reflected power it makes perfect sense. Try reading Reflections by W2DU. It might make sense then. Bird recommends using an absorption wattmeter for accurate foward power measurement. Did you catch that in the manual you just read?

The last test addresses the situation in question. Thanks. Bird 43 adds reflected power to forward power reading. Next.

Bob, put an easily measured amount of power into a controlled high SWR. Measure forward and reflected power with the 43. Tell us what you get.

My kilowatt rig works.

Yes any mismatch is abuse and all those dirty variables might just make this all go away :laugh:

The meter is reporting forward power correctly. Look at it in terms of what the feedline must be able to pass. 2:1 SWR means somewhere along that line there will be twice the voltage and current encountered with a flat match. The reflected power is not all lost. In some cases most of it does get...

True we don't want to charge caps during hi-pot testing and we disconnect them along with the bleeders. Testing the caps themselves is a PIA. A stack of old meter multiplier resistors is nice to have for that. Breakdowns in the rf areas are pretty easy to find without running the...

I've owned a few of these but didn't work on them. If the VFO was retuned and you want tune it back, look for added padder caps. Also could be a bandpass filter somewhere which would have needed a retweeking. Moving back to factory would require retuning that too. Not sure in your case but I've...

How would you guess these 2 people as not having the proper background? That's kind of a stretch. Incorrect guess also. Pop over to AMFONE and ask about W2WME. The electrician was trained for high voltage work too. The correct way to look for arcs is as mentioned before. Use a hi-pot tester...

Read it again you missed it. Got a Bird 43? Try it for yourself. Put a known wattage into a 50 ohm load. Replace the load with a 100 200 or 300 ohm resistor. Read forward power. It will increase. Read reflected power. Notice the forward power increase is the amount read for reflected power...

Plug "bird 43 manual" into a search engine. Excellent bedtime reading.

Any situation where one would want to defeat an interlock and probe a transmitter's B+ supply can be replaced by advanced troubleshooting skills period. The only time high voltage is necessary for component testing is when looking for hi potential insulation breakdown. This test can be...

Maybe someone screwdrivered the VFO over to 11.

A condition which can be checked with the circuit cold. Visual for carbon traces and ohm meter for opens. Not a good idea to encourage people on a radio interest forum to poke high voltage. A little troubleshooting experience will out most high voltage faults without poking around a hot...

No need to be afraid. It is right in the manual.

Your broadcast xmitters did not have working internal meters? What would you possibly measure in a broadcast box that factory metering wouldn't cover?

Any ALC indication on AM will sound like crap. A carefully adjusted audio compressor ahead of the mic input might help. Less power out might help too.

Not all power meters work the same way. The Bird 43 adds reflected power to the forward power reading. It is possible to read almost 200 watts forward power at the output of a 100 watt transmitter.

What do others do? Spend a little more time asking folks who actually build and use what they built. Then spend a little more time figuring out what the voltage will be. Since you are building, use a panel mounted meter. Poking high voltage should not be necessary. Save the Fluke...
