Re: [Elecraft] K3 - ESSB Availability
Hi Joe. Yes, I am also awaiting this firmware update. I have not yet got my K3, but my hopes are that it will be ready soon. Right now I am also using the IC-756pro3, microphone are the TSM MT-57 dynamic, and I use the W2IHY equalizer into the rear ACC connector. I have also ordered a better microphone, the AV Leader STM-11 : http://www.avleader.com.tw/product_Studio%20Microphones.htm This one has a very flat frequency response and needs an equalizer to sound good. This one also needs +48V phantom power, I have the small LEEM PHW-22 phantom power supply. This one is cheap, and it has selectable +48V or +12V. This is what amateur radio is all about for some of us, not just getting a message thrue but making it sound as good as possible.

Would like to try a little wider bandwidth (about 3.0) and see if I can match the PRO. Will need the 6.0 filter of course. The various dynamic mics I am using have gotten excellent audio reports using rigs like the Yaesu Mark IV, Kenwood TS-870 and etc. I have had three different people view my transmit bandwidth on their spectrum scopes and confirmed that my 2.7 filter is in fact transmitting at 2.7 bandwidth (not 2.9 as previous thought).

[Elecraft] K3 - ESSB Availability
Every time I see the term ESSB I see red. I wonder if these folks have ever read FCC Part 97.307 (a) Emission Standards: (a) No amateur station transmission shall occupy more bandwidth than necessary for the information rate and emission type being transmitted, in accordance with good amateur practice. http://www.arrl.org/FandES/field/regulations/news/part97/ Instead of playing wannabe broadcast engineer, why don't these folks try something really creative, like trying to see how *little* bandwidth they can use to communicate, instead of how much bandwidth they can consume? Icom has a lot of faults (like very misleading advertising) but I do commend them for limiting the bandwidth of their voice modes.

Re: [Elecraft] K3 - ESSB Availability
Every time I see the term ESSB I see red. I wonder if these folks have ever read FCC Part 97.307 (a) Emission Standards: (a) No amateur station transmission shall occupy more bandwidth than necessary for the information rate and emission type being transmitted, in accordance with good amateur practice. Bill, The problem with Section 97.307(a) lies in its drafting and purpose. The plain-language meaning of this section infers that as long as the transmission occupies no more bandwidth than that necessary for the emission type we are trying to achieve, then we are complaint with the rule, subject to good amateur practice. For example, suppose my intent is to use ITU designator 3K00J3E (i.e., 3 kHz SSB bandwidth). My intent is to use 3 kHz of occupied bandwidth and clearly, the ITU designator sets the emission type as stated in the aforementioned rule. Taking this one step further, if my desired occupied bandwidth is 3 kHz under the ITU 3K00J3E designator, then as long as I remain within that boundary I have set for the emission type being transmitted, I am fully-complaint with the rule (see my bandwidth boundary caveat at the end). In fact, suppose I wish to transmit with 6 kHz of SSB bandwidth and my desired emission type is 6K00J3E under the ITU designator. Pursuant to the rules, that transmission can be fully-complaint as well. However, this also presumes that any such transmission -- no matter what the actual bandwidth -- does not cause interference to existing transmissions. Whether the actual transmitted bandwidth is 1.8 kHz of 6 kHz, there's always a propensity to cause some interference to existing transmissions. Moreover, terms like good amateur practice and information rate should never be codified into rules regulations unless these terms are incorporated by reference into definitions in the preamble of the rules. Only, the original framers of Sec. 97.307(a) likely wanted to keep this section open for experimentation purposes without the necessity of placing hard bandwidth restrictions on emissions that could otherwise thwart the benefits of experimenting with various modes that exist today -- and those modes that may become developed at some point in the future. Enforcement of 97.307(a) would never, and could never, stand up to Constitutional scrutiny on the basis of the rule's arbitrary, capricious, and vague drafting. Another problem that surfaces when we establish hard occupied bandwidth rules is the necessity to monitor the bandwidth of emissions (to ensure 100% compliance) and the lack of a reasonable means for the average licensee to measure such. Also, codified bandwidth regulations would require setting measurement limits at the spectrum edges. For example, at what point is a 3K00J3E no longer compliant? Perhaps at -26 dB Peak Power? - 50 dB Peak Power? It gets real messy, real fast. Paul, W9AC ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

Re: [Elecraft] K3 - ESSB Availability
Oh here we go againStop trolling for flames guys. Now we will start this same old argument again. If one is so concerned about how much bandwidth they use then switch to QRP CW and forget about SSB.

Guys, lets nip this thread before it roars to life again. ;-) A quick search of the archives will bring all of the past pro/con ESSB discussions to light in excruciating detail. 73, Eric WA6HHQ Elecraft list moderator Paul Christensen wrote: Every time I see the term ESSB I see red.
