[Elecraft] K3 transmit out of band question

[David Anderson]

I am hoping to use a K3 to transverter from 14 MHz to 144 MHz with an existing transverter.

I need to cover from 14.000 to about 14.400 MHz on transmit for the weak signal end of the band.

I believe that the K3 can be enabled via software to transmit outside the limits of the ham bands. 

The question is do I require the general coverage bandpass filter option to allow transmission just for that extra 50 kHz above 14.350? 

I will be using the transverter output not the HF antenna for this.

Many thanks.
