Yes, some radios do provide that the ATU will automatically track the
transmit frequency. In other cases, the Eagle, the ATU will activate only
on user command of pressing TUNE. And every time TUNE is pressed, the ATU
routine will run. It does store the last values for the last band used. It
will store parameters for each band and when returning to that band, those
last saved parameters are automatically selected without running the TUNE
routine.

Subject: Re: [TenTec] Eagle AT slow?
Now I do not have an Eagle, but every auto tuner I have used, (LDG, and
the internal tuner on my Yeasu FT-950) the memory tune feature you do not
force a tune. One the LDG it sinces the frequency and it goes to the last
tune in memory for that frequency on the first carrier it receives. On my
FT-950 as I tune the VFO and the "tuner" is on, it will automatically
change the tuner as I spin the dial. But if I force a tune it will start
from scratch and find a tune.

I'd welcome some comments on the internal Eagle AT (Model 599AT).
Here's mine: On 3570 KHz, where my MFJ-269 shows the old trap doublet has
an SWR of 2.7, the Eagle took 15 seconds to tune. Leaving it on that
frequency, a minute or so later a second try also took 15 seconds. A
third tune, on the same frequency another minute later, took 10 seconds.
On 40m, where the SWR is 2.1, tuning takes 7 seconds.
I know the old antenna here at the camp needs work... but that behavior
on 80 doesn't seem right. The manual (p. 37) says the AT is "designed to
recall the last tuned setting for a given band." Maybe I don't understand
how that memory works, but I don't think the MFJ-293B that I have at home
would behave like this.
