I haven't noticed anyone else offer this idea, so I'll jump in here. I often
see low level signals all through the 2M band near digital equipment. This
is especially true of devices equipped with RS-232 interfaces. The baud
rates are often generated by dividing down a higher frequency crystal

Thanks for that !
Yes, it does have three slots for horizontal modules. They are filled
with a PL module and the Intercom module.
So I would say it's a full duplex unit. When it was in service it was
used with Wireline control.

A 70 or 100 ns device is faster than the 150 ns. This is the access time min
required to read/write to it. So if writing say at 500 ns still the 70-100 ns
devices will still work.
The device will now also work with faster computers.

Thanks for the response. Since the CPU that queries the clock chip is part
of the controller, I wasn't sure that the shorter access time of the newer

Not really sure but when they changed the notch filter the spurious signal went
away. It was a fairly strong carrier.

I've been toying around with this idea for a couple of years - set the SCOM

with their time of day clock.
The idea is to have a stable WWV signal that listen to the top of the hour
