I am posting this message to the list and to Dwayne at LDG, since
recently many of us got new tuner kits.
How long does it take for the tuner, QRO or QRP, to go to sleep?
I didn't see in the manuals anything about the time interval between
active and inactive (sleep) mode.
I noticed that the QRP tuner can be put to sleep in either auto
or semi modes by press the CAP and IND switches together.
If you made the correction to the wiring of these switches that
I posted earlier, you have to press the two toggles UP at the
same time, not DOWN as the manual describes.
That change was to made to the QRP unit to make its operation
the same as the QRO unit, i.e., UP on the toggles means increase
CAP or IND, not to decrease them as wiring according to the
manual would do. The QRO tuner uses SPST pushbuttons, not SPDT
toggle switches, but the operation should be the same as the silk
screening shows on either unit. SPDT toggles actuate the reverse
terminal from the toggle position.
I'm listening to my QRP tuner now with a big "birdie" at about
14.147 MHz to see if it ever goes to sleep on its own in the
semi mode. So far, as I write this, it hasn't.
I don't know about the behavior of the QRO model, since I just
removed the uP from it and returned it to LDG for a software
(firmware?) upgrade, and my unit was purchased Feb 16, 1996
and had the old code in it.
Just wondering what the story is here, and figured the rest of
you might be interested too. BTW, the QRP tuner is still "awake" as
I finish this.
