[time-nuts] Simple 5 to10MHz frequency doubler

Hi I have just broken up an old 10-Base-T 16 ay switch and recovered 16 DIL
filter/isolating transformers ( identified as a 10F434 from YCL) ....and the
spec an pin-out was still available on the YCL web site.....worth a look for
10MHz distribution??

I am concerned that a narrow 10MHz filter might give significant phase
shifts (the YCL is a LP) is this likely to be a problem??
