3cx3000 amp with high SWR when hooked up ??

[Sscottert1]

I have a 3cx3000 amp that I haven’t used in a while because I just moved . I was setting up my equipment again when I noticed with my rig expert that my SWR was around a 2.5 So I was investigating the source of the high SWR because I know my antenna system was 1.1 . Long story short with just the tube amp inline and the antenna I have 2.5 . I also tried messing with the load and tube and input tune on the amp when off but still Didn’t change any idea what can it be ?

Could be a relay, bad coax connector or bad jumper. It's something simple.

The tune and load won't do anything for this. When the amp is off or in standby think of it as a big barrel connector.

Try this, put a dummy load on the antenna side of the 3000 amp, the sir meter on the input side and check the sir through the amp, if the sir is high then the pss through sir is what you are seeing, a technician familiar with amps will be able to help, usually the long and/or open leads inside the amp causes this, usually can be corrected with capacitance on the feed through .
