Hmm sorry for all the replies to myself.. it seems like we're talking about
the same thing. What I meant to say was TOD but missed by 1 letter which
would be the same thing as what you said... have-quick timing signal..

HQ *TOD*   = *HAVE QUICK* TIME OF DAY - MICKEY TONE FREQ

Following from www.geocities.com/illuzion30/2a4x2/uhf-fun.htm which looks
like a good learning site about HaveQuick..

To accomplish frequency hopping, both users must have a pre-established
channel-hopping pattern as well as a number of preselected frequencies, of
course, they need to synchronize their systems so that they are also on the
right channel at the right time. The WOD or Word-of-the-Day determines the
pattern, rate, and dwell time, and can either be transferred via a
cryptographic loading device or manually input. To synchronize internal
clocks, you need a valid TOD or Time-of-Day. You can receive TOD from a
ground station, aerospace vehicle or even another system like GPS. TOD from
one of these sources will allow you to use havequick and communicate with
any other aircraft worldwide. However, if you do not have a universal TOD
available, or do not wish friendly aircraft to listen, you can randomly
generate your own TOD, which will be out of sync with other aircraft. Then
you can pass your random TOD to aircraft of your choice for communication
with only those aircraft which you have passed your unique TOD to. Finally,
you need to choose a net number which is the actual table of frequencies you
will be using. This is selected with the frequency select knobs on the UHF
control.
