[Elecraft] [k3] Mic Gain: Option 7

[Sam Morgan]

Page 20 K3 Owner's man D10.pdf

MIC
MONO; hi- or low-Z
This jack accommodates an electret or dynamic
mic. Use MAIN:MIC SEL to select the rear panel
mic (RP). Tap 1 to turn on Low or High mic gain
range. Tap 2 to turn bias on/off (see pg. 28 for
recommendations based on mic type).
For the front-panel mic only, additional microphone
gain can be enabled by tapping 3 . Use this only for
very low-output mics.

MIC SEL
Mic/line transmit audio source, mic gain range, and mic bias. Source 
selections:
FP (front panel 8-pin MIC jack), RP (rear panel 3.5 mm MIC jack), and 
LINE IN
(rear-panel LINE IN jack). Tap 1 to toggle between .Low and .High mic 
gain range
for the selected mic. Tap 2 to turn mic BIAS on/off (turn on for 
electret mics).
For the front-panel mic only, tap 3 to turn on an additional gain stage. 
Use this only
with very low-output mics. An apostrophe will appear after the H, e.g. H’ .



only place I find tap 7 in the manual is under FLx BW on pg 55
also mentioned on pg 24


however when in the MIC SEL menu for the front panel mic
taping 3 gives a N/A result

taping 7 *WILL* give the desired mic boost for the front panel mic

taping 3 or 7 gives a N/A when rear mic is selected

I just checked in the ERRATA for the K3 Owners manual and it's not there 
either

looks like there needs to be an editing job in the manual ;-)
