Wayne, Am I correct in my understanding that the reason the 2.1 is not currently allowed is simply a firmware issue?
If it is indeed technically OK to use the 2.1 instead of the 2.7 or 2.8, yes - I would like that option to be available. I was surprised that after removing the 2.7 and installing the 2.1 that its selection as a transmit filter was precluded. The 2.1 is much better than the 2.7 for SSB reception, and if it is OK to transmit through, I would not need to waste a filter slot on the 2.7. 73, Bob W5OV -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of Wayne Burdick Sent: Friday, October 08, 2010 11:56 AM To: Bob Naumann Cc: [email protected] Subject: Re: [Elecraft] FM Filter for AM? Bob, I could change all of the transmit filter bandwidth restrictions in firmware, and this is on my list. But it would be a complex change, and I have to weigh it against many competing firmware change requests. I assume the presence of a 2.7 or 2.8 kHz filter in all of the frequency-setting algorithms for SSB, CW, and DATA modes. Similarly, I assume a 6 kHz filter for TX in AM and ESSB modes. 73, Wayne N6KR Bob Naumann wrote: > Can someone explain why this restriction exists? > > *Why* can't you transmit through a 2.1 filter for example. *Why* is it > precluded? ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
