K4

Will the k4 with Mars software transmit from 1.8 through 30 Mhz with no band stop

like the K3 has at the IF freq?

The K3 will transmit and receive in the 8 MHz range as long as you're using direct sampling mode. The HDR module (in the K4HD model) has an 8 MHz I.F., like a K3, so it would have to be turned off in this case.

He meant K4, of course. Good thing he didn't accidentally type "K5" or
it would have given rise to another 48,674 queries.

He meant K4. I spent a while thinking about that myself. Has to be K4 as he later mentioned turning Superhet front-end OFF in order to get to Direct Sampling mode.

Sorry about that. The K3/K3S is strictly superhet.
