[Elecraft] K3: what voltage is needed for ALC input (p.15 of ACC)

[cw at dx.nl]

Sorry subject of previous posting was not indicated what radio I was
talking about
==========

Scanning through the K3 manual (Rev A2) I saw that the ALC voltage to be
applied on
pin 15 of the ACC connector needs to be in the 0 - +5V range. This worries
me a bit
because many (if not virtually all) linear amps output a NEGATIVE ALC
voltage for feedback to the transceiver.

I currently use my FT1kMP which needs 0 ~ -4V in combination with a SPE
1K-FA
solid-state amp.
It is fully interfaced including the ALC and that is working very well.
The SPE outputs between 0 and -11V regulated by u-processor such that the
right output
is generated

Is the +5V maybe a typo (i.e. should it be -5V) ??
