[WriteLog] Serial numbers with preceeding 'T' instead of '0'

[Richard Thorne]

I have my cw memories setup to send 5nn %3 for wpx so when the serial 
number is sent I will get TT1 when sending 1.  However I'm getting 
preceeding 0's , ie 001 is being sent.

So where in the setup do I change the 0 to a preceeding T?

Thanks
