Grant,

You didn't say what Yaesu rig you are using but I had the same problem after 
my FTDX9000 went through the PEP program.  I don't know what changes Yaesu 
made to the keying circuit.  I discussed the situation with Steve, K1EL and 
the fix is very simple.

I am guessing that you have a keyer with optocouplers controlling the output 
ports.  These optocouplers are identified as U1 and U3.  You can remove the 
optocouplers from their sockets and replace them with solid state relays. 
No other changes are required.  The solid state relays are part number 
AQW210EH.  Steve was going to send me the relays but it didn't happen and I 
didn't want to bother him because he was recently in a serious automobile 
accident.  I purchased the parts from Newark, www.newark.com.  They cost 
$5.73 each plus shipping.  K1EL sells the WKUSB with these parts if you 
order the "HV option".

Carl, WA2ETU
