> Is there a reason why you chose 50mhz instead of 28mhz for the IF? Yes. We use the LO*4 signal from the synthesizer to drive the 2-meter module's down-conversion mixer, and the math for this puts the I.F. at 48 MHz when R.F. is 144 MHz. If not for this fortunate result, adding 2 meters to the KX3 would require a separate, high-stability TCXO running at around 190 MHz. A lot more expensive.
