[JMS] Millen stuff

Wed, 12 Nov 2003 09:13:06 -0600

Hi Don,

It's good to hear from you. I'll check on the supply when I get home 
this afternoon. The pictures are a bit low resolution and I hope to 
correct this as well. I am not getting totally out of Millen gear as I 
will use a Millen exciter to drive my AM transmitter and also a 
monitor scope.

Thanks,
Tom  N5AMA
