[CQ-Contest] Palstar-AT2K help

[Carol Richards]

 Hello,

I recently acquired a Palstar AT2K tuner and it seems to work fine except for one issue which just cropped up. When I push the button to see peak output, the button works but the function does not. The schematic is of no help and repeated calls to Palstar result in a busy signal. 

Is there anyone out there who can point me in the right direction to help cure this problem?

Thanks,

Carol
