[TenTec] TenTec Corsair II 561 or antenna issue

[KB8OCA]

HI everyone,

>From the title you can see I own a TenTec 561 Corsair II, and it has been working very well so far ... until this past Saturday evening.
The TenTec is connected to a G5RV via a manual tuner, which all has been working very well for me.

The problem now is, that folks are saying my audio is all garbled to a point where they can not understand one work I am saying. Also, when I key the radio, the power meter immediately goes up mid scale, without me making any sound what so ever.

I then decided to work with my ALC control, speech processor and the drive control, but that had very little effect. Even is my ALC is turned all the way clockwise, speech processor is off, and drive is let's say at 0.5, I can hear a beeping sound right away.
Despite all of this, my SWR indication is correct, below 1.2 : 1

I then disconnected the tuner and antenna, and connected a dummy load directly to the radio.
Now everything seems to be back to normal. I can adjust the radio the way I expected it etc.

>From that I assume I am having antenna problems, the thing that does not make any sense however is my SWR, which is perfect .....

Do any of you have any ideas what might be happening here ?

Like I said this started all of a sudden. It was working Saturday morning, and by Saturday evening it was like described above. It was still the same on Sunday, and yesterday as well, so something sure changed.

Thanks for your help.
