Re: Elecraft K3 lock power control

[LDZ]

Thanks Keith

Yes. I have been using the lock function to date.  And will carry on in that way.

The issue of what I am trying to do comes up as we are using an amplifier that is not compatible with the ALC control on the K3S therefore the need to minimise the risk of overdriving.  It would be nice to have some flexibility in that for less experienced users (especially as it is my radio I am lending to the club!) so that they can experiment with the power levels up to a set limit, without me risking my radio.

I fully appreciate that if this were in a KX500 setup none of this would be necessary but maybe it could be considered in a future iteration of the software.

cheers for the response.

Hi Trevor; I saw your post. This has baffled me when a radio comes in for repair and is LOCKED.
You can use it for your club operations to lock the power control. Unfortunately, they cannot go LOWER in power either.
(the word LOCKED is NOT in the manual, so hard to find this).
(We can set the max power here at the factory but it would require a trip here and back here to un-do the limit- Japan has a 50W mobile limit).

LOCKED shows in the display when attempting to set pwr power mic comp compression controls.
FiX; Tap 1 in “PWR SET” menu.
Tap 1 to LOCK or UNLOCK the MIC, CMP, and PWR controls.

PWR SET NOR If set to NOR, the power level on each band follows the present setting of the
PWR control. If set to PER-BAND, the power level is saved on each band. This
is especially useful with external amplifiers (see ALC discussion on page 82.)
If a KPA500 is connected to the K3S via the ACC cable, two sets of per-band
power settings are saved: one for “barefoot” operation, one for use with the amp.
When the amp is used, an asterisk appears as PWR is rotated (e.g. 30 W*).

I've not used ALC from the amp to control the transceiver power in years.  Just set the transceiver power to the required power during tune up of the amp and let the superior transceiver ALC do its job.  This greatly prevents ALC overshoot.
