[Elecraft] [K3] Transmit AM through FM Filter?
Checked the archives, but unable to find an answer. If I was to purchase ONLY an FM filter, can I also TX AM through it without issue? I know RXing is not a problem.

Dan, The 'without issue' part is important here. While it could possibly work, to work with spurs and other 'bad things happening' is not likely. The 6kHz filter is for AM transmit. The K3 may even prevent AM transmission if that filter is not installed, but I don't know that for certain. 73, Don W3FPR Dan Atchison wrote: Checked the archives, but unable to find an answer.

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.

[Elecraft] [K3] Transmit AM through FM Filter?
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?
