SSB Mode
Use the steps below to do initial SSB setup:
§ Set PWR to 0.0 W.
§ Tap MODE to select SSB (either LSB or USB).
To change SSB modes, use MENU:ALT MD.
§ Tap
AF/MON to set the voice monitor level.
Start with 3. High settings may sound distorted.
§ Set MENU:TX CMP (speech compression) to 0
initially. Exit the menu.
§ Tap XMIT or hold in the mic’s PTT switch. Note:
Hand-held mics like the Elecraft MH3 should
nearly touch your mouth when you are speaking.
§ While speaking into the mic, adjust mic gain
( MIC). This will turn on the transmit CMP and
ALC bar graphs. While speaking, adjust mic gain
for about 5 ALC bars (see below). Mic gain for
the Elecraft MH3 is typically set to 15-25, and
30-40 for the internal mic.
§ To use speech compression, set MENU:TX CMP
to 10-20 initially. Compression increases average
“talk power” with only slightly decreased fidelity.
§ Exit transmit mode. Set PWR to the desired
level. Do not use MIC gain to set power level.
Set mic gain to a fixed level as described above.
VOX Setup
Several menu entries are used to configure SSB VOX
(voice-operated transmit):
If MENU:VOX MD is OFF (PTT, or push-to-talk
mode), the transmitter must be enabled by tapping
XMIT or by holding the mic’s PTT button. With VOX
on, the VOX icon turns on, and transmit starts by
speaking. If VOX is on, the remaining menu entries
below should also be set up.
VOX cannot be used with the built-in
microphone. Use the XMIT switch to transmit.
MENU:VOX GN (VOX gain) should be set to trigger
at normal speech level, but not in response to
incidental noise. Start with low settings (10-20).
MENU:VOX DLY sets the VOX (voice-operated
transmit) delay time in seconds. A setting of about 0.5
seconds will keep the radio in transmit mode during
typical continuous speech.
MENU:VOX INH (VOX inhibit, or anti-vox) can
prevent speaker audio from triggering VOX.
Transmit Metering
In SSB mode, tapping MIC switches the transmit
bar graph from SWR / RF to CMP / ALC.
The CMP / ALC scale is selected automatically when
you adjust mic gain or speech compression. The
SWR / RF scale is restored after a few seconds.
