This links into another problem about data bandwidths: unlike the specific DATA sub-mode, the associated passband settings are not saved per-band.
Whenever you select DATA, the stored SHIFT and WIDTH settings will always be the last settings that were used for *any* data sub-mode on *any* other band... which may often be quite inappropriate. This is a particular inconvenience for all users who switch frequently between narrowband data modes on HF and wider-band modes on 6m and above. (It obviously isn't a major problem; I only mention it in case Elecraft might be revisiting this area of code.) 73 from Ian GM3SEK >-----Original Message----- >From: Elecraft [mailto:[email protected]] On Behalf Of >David Anderson >Sent: 29 July 2015 22:28 >To: Elecraft Reflector >Subject: [Elecraft] [KX3] DATA A v SSB maximum receiver bandwidth not as >wide. > >Experimenting with the KX3 on WSJT FSK441 and JT65b I noticed looking at >the spectral display of band noise that with the bandwidth widened fully >out on DATA A Mode that even though it was displaying 4 KHz on the KX3 >LCD, the bandwidth of the audio was less, like 400 Hz to 3600 Hz. > >On SSB mode it was possible to get the full 4 KHz by suitable manipulation >of the width and centre frequency. > >It is useful on JT65 on EME if you are running a pileup from a rare DXCC to >have stations spread out and having the full 4 KHz is beneficial then.
