Tom, Are you saying that because the bird meter measures both voltage and current that it will read right no matter what the line impedance is that it is connected to? This of course subtracting refl
Hi Tom, I finally drug out an old bird 43 manual from 30 some years ago and read it again. It pretty much describes the operation as you describe it. But they do go on to say a bit about operating it
I think some of you guys are reading the wrong info. The commercial short-wave broadcast stations have some bandwidth specs but not hams. 73 Gary K4FMX
Rich, How did you come up with 4.5 kc offset? I am assuming that you are using the receive filter on the same side band with that offset? With that setup I would think that you would only see the pro
Good points Rich, listening will certainly catch things like alc problems that a 2 tone test will not. I am an advocate of using the receiver as a piece of test equipment. Probably the best in most s
Bill, What you are saying here is what no one else wants to talk about. This has been the contention of the discussion from the start. With an open circuit at the output side of the meter there is no
I just read the original Bruene description and it doesn't give any information about open termination's either. He only discusses impedance's close to design impedance.. Well I just drug out an old
That is what I said from the very start, "there can't be any power if there is no current in the line". Yes I understand subtracting reflected from forward power readings and agree with that. What I
I need to rewind the magneto coil in a megger. It has #43 wire. About the size of your hair or smaller. Need about 5000 feet. Or if anyone has a JVC megger that has a bad meter or otherwise with a go
I don't think that is right. I did another test with the same setup but this time I used only a 1000 ohm resistor for a load and no capacitor. Transmitter--watt meter--tuner--drake watt meter-- 1000
Hi Ron, Yes I would agree with you if there was a transmission line involved. But in this test the load resistor is connected directly to the watt meter no line involved. Between the tuner and the wa
Hi Ron, Yes that is exactly the point I am saying. Even though the load may be perfectly flat, no reflected power, the meter will show what would seem to be reflected power when there is none. This i
As Colin says, the whole problem is attack time of the ALC. Doesn't anyone make a radio with proper attack time? It can't be that hard to do. It is simply like the AVC system in the receiver. On any
Actually moist concrete is a very good conductor. Connecting to the rebar in the concrete makes an excellent ground system. But you need to weld the connections of the rebar inside the concrete or wh
It is best to bond everything together. However grounding does not prevent a lightning strike. There is nothing that will prevent a strike. It is impossible to bleed off the charge buildup. The earth
Hi Rob, You are about right on not having a separate safety ground and a separate rf ground. But don't clip off that ground pin. I am looking at it more as a lightning ground but as you will see it a
