In AM, both side bands have to fit through the filter so you're audio bandwidth is actually half of the RF bandwidth. With SSB, since there is only one sideband, you get audio bandwidth which is equal to the RF bandwidth.
SSB - 6 KHz filter gives 6 KHz audio bandwidth. AM (2 side bands) - 6 KHz filter gives 3 KHz audio bandwidth. - Keith N1AS - - K2 5411.ssb.100 - - K3 Wave 3 - -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Fern Rivard Sent: Wednesday, March 26, 2008 1:26 PM To: Elecraft Reflector Subject: [Elecraft] re bandwidth select on am mode re K3 On my K3, on ssb mode, I can select the wide am filter position but if I go to the AM mode, the widest bandwidth shown on the display is 3 khz! Should it not go to 6 khz as I do have that filter installed and it works on the ssb and other modes except for the AM mode. Any clarification or help with this would be greatly appreciated.
