That is not what he is saying. If he removes the amp from the line and goes radio to dummy load the swr is good. That is probably what he means.
Yes but I asked the question to get an idea of exactly what is going on. So hopefully he will check the VSWR reading either side of the Amp when in the Standby position, and post the answer . . .
Now you have me confused. The problem is while in standby (pass through) measured SWR going from the exciter to the amplifier is high on the higher bands (20-15-10) with the amplifier output connected to a 50 ohm dummyload. Out of the amplifier I also have a SWR meter between the amplifier and dummy load measuring SWR just to make sure that the dummy load was showing a perfect match to the amplifier output connector. My goal is to get the SWR as low as possible while in standby (pass through) between the exciter and amplifier. I hope to have time here soon to try the capacitor in the circuit to see if that makes a difference.
it will fix it the value needed may vary a bit between 20-40pf from the relay cross bar to ground . ive done this quite a few times
I installed the 33pf cap and greatly reduced pass-through SWR. Going to try a few different values when I get them to tweak it. Thanks for advice on correcting this issue. Thread is closed now. I think we beat this one to death.
Yes but as I keep asking . . . WHAT DOES THE SWR READ ON THE OUTPUT OF THE AMPLIFIER when in the Standby position? Why won't you answer this question?!
Maybe he doesn't understand the question as you write it? I am not sure what you are asking either. Maybe this is what you mean......"What is the swr of the load (antenna or dummy load) with the swr meter inserted in the coax after the amp's output connector but before the load while the amp is in standby" Is this what you are asking? If this is NOT what you are asking then tell us where you want the swr meter placed, exactly, and this is where you want the swr measured from the load.
