CW RX pitch / TX sidetone

Select RX pitch frequency between

 

 

frequency

400Hz and 1000Hz. At the same time,

 

 

sidetone frequency changes with the

 

 

 

 

 

 

pitch frequency. This can be used to

 

 

 

zero in on a target signal by matching

 

 

 

the sidetone frequency with the RX

 

 

 

beat.

 

35

CW keying weight ratio

Change the dot/dash weight ratio. This

 

 

 

is usually set to AUTO.

 

36

Reverse CW keying auto

You can change the AUTO setting for

 

 

weight ratio

#35.

 

 

 

 

 

 

 

 

37

Bug key function

Manual TX can be enabled for dashes

 

 

 

only.

 

38

Swap dot & dash paddle

Swap the paddle position to suit either

 

 

position

right-handed or left-handed use.

 

 

 

 

 

 

 

 

39

Auto CW TX in SSB mode

Automatically switch mode to CW

 

 

 

transmission by simply operating the

 

 

 

paddle.

 

40

Define CW tune frequency

Useful if used in combination with #39,

 

 

 

as there is no need to operate the dial

 

 

 

to zero in on a target.
