As far as I know, the K3 filters are not intelligent, the K3 has no way of knowing what the filter is other than by your setup. If the FM filter was defined as a 5 khz filter, the K3 would probably send the signal through it and the signal would probably be spectrally purer than the vast majority of the gear that's being used on AM today. But the only way to find out would be to put it on a spectrum analyzer. Elecraft has spoken of removing the firmware block at some point in the future. There is also a block that keeps you from transmitting out of band, which is annoying when you're connected to a dummy load.
[Elecraft] [K3] Transmit AM through FM Filter?

If I was to purchase > ONLY an FM filter, can I also TX AM through it without issue? The current firmware blocks the use of any foilter for AM Tx other than 6 kHz. 73, Lyle KK7P _______________________________________________ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.
