[TMC] AN/TSM-16 or FR-114/U?

[Chris Bolkan]

Hi Eugene!
It was great meeting you at Hamvention. That's a cool frequency counter and
will be a nice (period correct) addition to the VOX once you get it set up.
You have some nice TMC there! I'm particularly envious of the Matching unit
display. Someday I hope to acquire one of those!
It sounds like your plan is to connect the counter to one of the output
ports on the oscillator to directly display the multiplied output frequency
as opposed to "T"ing off the 2-4 MHZ master oscillator? If that counter
went to 2 Mhz instead of 1 you could have hooked it straight up to the MO
without having to do any mods whatsoever, with the only penalty having to
do a little multiplication to get the actual value. But since you have to
make a divider anyway, might as well make it read the actual frequency!
Take care!
Chris
