[Elecraft] K4 on AM

[Wayne Burdick]

Hi Grant,

The K4 will allow independent setting of TX bandwidth for voice and audio data modes up to something in excess of 4 kHz. SSB, ESSB, AM, and audio data will each have their own setting.

As with the K3S, it'll be up to the user to judge whether the use of wider bandwidths is acceptable under the given operating conditions. This subject will be discussed in the owner's manual.

I certainly hope the design options substantially exceed the rather poor and restricted transmit bandwidth of the K3, and that there aren’t any unnecessary artificial “political” restrictions.  It would seem that the K4, like the Flex radios for example, should be capable of providing outstanding, clean, AM transmit performance with adjustable transmit audio bandwidth to suit conditions, etc.
