I have to believe that this one is at least to some extent referring to me as I
am a huge fan of the x-lock. Anyone who thinks that their rig is a NBS device
is dreaming. OTOH the reality is that the x-lock tends to make the drift w/i
the TR7 manageable.
Anyone who understands the technology knows that all x-lock is doing is "bouncing" the freq around
a small freq "slot" and clocking that against a more stable reference. The rig is more stable than
letting the PTO "free run". That is only slowing the entire process to a point so that we humans
do not notice it as much.
No harm, no fowl. Just comments.

Some days I am more easily amused than other days.

What led me to the above link was a discussion of drift in
the IC-706 radios on another list. It also reminded me of
the ongoing discussions on this list of huff-puff
stabilizers for our "drifty" TR-7s. What's new is old,
what's old is new.
All kidding aside, this idea might be a good approach to
tame those pesky 40 MHz reference oscillators in slaved
7-Twins. I'll have to put it on my round tuit list.

It is posting like this I prefer bottom. I do not know who sent to whom
or which IS top/bottom in the above example.
Can you imagine a LONGER list?
Also:
People also need to TRIM their replies .... it makes for cleaner reading.
OK, my 2 and 3/4 cents (adjusted for inflation)
