[CQ-Contest] Fwd: Palstar-AT2K help

[Carol Richards]

Hello all

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 Peak Hold 
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
