- WIDER SSB BANDWITH ON THE ICOM IC-761 WITHOUT ANY
- MODIFICATIONS
- When in SSB mode and the filter switch is in the "out
- position", your normal bandwidth is 2.6kHz. When the filer
- switch is in the "in position", your normal bandwidth is
- 2.4kHz. I have noticed there is a 3rd SSB bandwidth for
- receiving in the SSB mode. Leave the filter switch in the
- out position and place the IF shift button in the "in
- position" for IF shift, and now the bandwidth is 3 to 3.2kHz
- wide. When using the filter switch only to select the
- advertised wide and narrow position for SSB bandwidth, you
- receive and transmit at those bandwidths and are using both
- the 9MHz and 455MHz filters; however, when using the above
- method as stated for the wider selectivity, it appears you
- are receiving through the wide ceramic 455MHz filter only,
- and bypassing the 9MHz filter. So there are three positions,
- not two.
