You have to use the 6 KHz filter for TX on ESSB. You're TX is probably restricted on audio bandwidth with the 2.7 filter.
From hfnotes.rtf for 2.23: * ESSB (EXTENDED SINGLE SIDEBAND) ADDED: Allows the K3 to transmit in SSB modes at a bandwidth of up to about 4 kHz. Requires a 6 kHz crystal filter on the RF board. To use ESSB: (1) Make sure the 6 kHz filter is configured correctly for AM transmit; switch to AM mode, then specify this filter using CONFIG:FLTX AM. (2) Locate CONFIG:TX ESSB. Select the desired extended bandwidth for SSB ransmit (3.0 to 4.0 kHz) using VFO A. Then tap"1" on the keypad to turn ESSB on/off. When on, the "+" icon in the mode area will turn on. 73, matt, W6NIA On Sun, 03 Aug 2008 23:15:47 +0100, you wrote: >Hi all, >Out of interest I thought I would try the new feature.
