Paul, M1CNK asked:
How well does the T1 auto tuner remember frequencies within a band? I am
looking at making a vertical for 80m that will have a relatively small
bandwidth (say 30-40kHz). Therefore, I am wondering whether I could put a
T1 auto tuner at the base of the vertical with a remote tune switch. I'll
be using my K2 so currently no option for using the band data.
Does the T1 remember individual frequencies within a band and also measure
the incoming frequency to speed up the retune or will it have to start from
scratch every time?
-------------------------------
It sounds like you can count on the T1 being ready to operate in 2 seconds
or less after changing frequencies, Paul.
As I understand the algorithm, the T1 simply keeps a memory of recent
settings that resulted in a match. When you launch an auto-tune cycle, it
first runs through those memorized settings to see if one produces a low SWR
on the link to the rig. If you're returning to a previously-used frequency
it'll find the match using the previously-stored setting very quickly (1 to
2 seconds).
Only when it's gone through the previously-stored settings without finding
match does the tuner then launch through the whole tune-up process looking
for the best match. That can take several seconds. Of course, once found,
it's written to the memory for quick recall later.
