However, I just compared the receiver section of the K144XV the XV144 and, apart from the relay versus PIN diode switch, they are essentially identical. I say essentially because a component value may be slightly different due to stray or parasitic PCB layout differences, but the circuit topology and active devices are identical. > 3.

The internal 2m module has its own set of switched IF connectors on the KXV3A (not KXV3) interface. External Elecraft transverters hook up to the external jacks. If you use external 2m and 70cm Elecraft transverters, they will both conenct tot he K3. > 4. IF the K3 has two receivers, can one listen on 2 m and the other on 70 > cm? >
I believe the answer is yes, *but* one will have to be interfaced using the regular antenna connections. The KXV3(A) only provides connection to one receiver. This is not compatible with the usual "daisy chain" configuration of XV-series transverters. 73, Lyle KK7P ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
