WPM - "Words Per Minute" while in CW mode. This adjusts the Morse sending rate in
•
"Words Per Minute" when using Iambic mode keying. Button M3 may be used to
select whether this encoder adjusts WPM or RIT (see below) with the "un-selected"
item being "grayed" out. The Morse WPM setting may is also adjustable from the main
menu. When not in CW mode this is replaced with "MIC" or "LIN".
MIC or LIN - "Microphone Gain" or "Line Input Gain" when not in CW mode. This
•
adjusts the Microphone (or Line Input) gain, depending on which is enabled. When in
CW mode this is replaced with "WPM". Pressing-and-holding button M3 will select
Microphone or Line-Input modes. Note that if this is changed during transmitting,
one must briefly unkey for the change of inputs to take effect.
Automatic switching of on-screen items when going from receive to
transmit:
Using the item in the "Configuration Menu" labeled "O/S Menu SW on TX" and setting it to
ON several of the on-screen items will change automatically when going from receive to
transmit and back again when returning to receive when in SSB mode: This function is
NOT available in CW mode. These parameters include:
CMP (in voice mode)
•
MIC or LIN (in voice mode)
•
This automatic switching facilitates the adjustment of the relevant parameters when in
transmit mode without having to pause and press the M1 and/or M3 buttons to switch the
functions of the relevant knobs.
Note that if you already had selected an alternate function while in receive (e.g. "CMP") it will
"remember" and return to that setting after you have been in transmit and again turned to
receive.
Setting the parameter " O/S Menu SW on TX" to OFF prevents the above parameters from
changing when going between receive and transmit.
