[CQ-Contest] Keyer problem

[trogo@cfl.rr.com]

While at HC8N my trusty DJ2BW keyer failed and I can't get the problem 
resolved.
I'm afraid it's the chip but maybe not if there is a way to completely 
do a total
reset.

Everything seems to work ok except the speed.  When it powers up it's 
supposed
to default to 20 WPM but mine starts at about 8 wpm and I cannot get 
it adjusted.
When trying to set the speed according to the manual I get an error 
sound after
I send the "s" in the function mode.

The variable speed pot works but max is about 8 wpm and minimum is 
about 1/2
wpm.

Any suggestions?  This keyer uses the same logic as the Logickeyer and 
a couple
of others.

Thanks
