Hi Joe, interestingly you CAN transmit AM with the FM filter! But it just works for one over. ;-)) Found it out by chance during the last few weeks with the nice 10 m conditions when tuning to the AM portion of the band. I only have the FM filter fitted (besides CW/SSB filters) and running firmware 4.42 beta (not tested with other ones) I can transmit in AM. Just AFTER releasing the PTT I will get an TXFILERR on the VFOB display and will not be able to transmit anymore. You need to power-off and on the radio then to make it work again. As that is no good QSO practice and you probably miss a few sentences from your QSO partner during "K3 reboot" I just did one QSO that way (and furthermore I am not really interested in AM just wanted to try it out). ;-))
Just my observations on that topic. Besides I completely agree with you, I do not see why you should not be able (or better "allowed") to transmit AM through the FM filter ... 73, Olli - DH8BQA ----- Original Message ----- From: "Joe Subich, W4TV" <[email protected]> To: <[email protected]> Sent: Monday, November 07, 2011 6:13 PM Subject: Re: [Elecraft_K3] Re: Close to Ordering > > > If you wish to transmit AM, you'll need a 6 kHz filter. > > > > If you wish to transmit FM, you'll need a 13 kHz FM filter. > > This still bugs me ... *WHY* won't Wayne enable AM transmit > with the FM filter?
