This is the K3 Rx bandwith with FW version 3.38. The audio bandwith is from 50 Hz to 3200Hz when I set the WIDTH at 4Khz and the SHIFT Fc at 1.2 Khz but it can be as wide as 4Khz If the WIDTH is opened wider.
This picture shows the Tx bandwith of my Elecraft K3 with my own voice and the AKG D88S mic using the 8 bands builtin EQ.Graph shows the audio response is from 80 to 3100 Hz for an actual total bandwith of 3.0 Khz.This sample was analyzed using my former FT-2000 opened AT 4 Khz
And this other audio graph shows the actual bandwith of my K2 using the KENWOOD MC-43S handheld mic ,this radio has no builtin or external EQ,so what you see is what the radio is capable to produce with my own voice,a well balanced response from 180 to 2600Hz. I also want to thanks Mr Don Wilheim for having tuned my K2 to its best specs including all four filters bandwiths.
Before starting to read my bio,I want you to click on these four links and see the wonderful movies about hamradio that make us feel proud of what we do for the community. http://www.youtube.com/watch?v=5Z9136_Nhh4 http://www.youtube.com/watch?v=8cMviApcohw&feature=related http://www.youtube.com/watch?v=y3gRWG-EUGU http://www.ksbw.com/video/19881725/index.html If you liked this great presentation by Walter Cronkite and want to have the whole movie on your PC,go to my own web page at www.ad4c.com and click on "downloads" and find the file named "amateur radio today" Also you can access now If you want my big collection of pictures clicking on the next link: http://community.webshots.com/user/ad4c2006 As far back as I can remember, hamradio has been my passion since I was a kid. At age 13, I played with my dad's ham station one day he was at work knowing that was illegal in my country,but teenager is a teenager,I didn't care,just wanted to have fun and find by myself If I could do what he did everyday,then after figured out how to turn the receiver and separate AM transmitter on and tune them on at 40M,called cq pretending I was my old man,then suddenly a station who happened to be my father's friend answered my cq and asked If I was (he thought I was my dad) sick because my voice sounded different like having a cold,I was scared and replied him telling certainly I was sick,but the guy didn't buy it and inmediately after we exchanged some reports and signed off,he called my dad to his office and told him what he heard from work he gently asked If I was operating his station and I had no choice to tell him the truth otherwise I was going to be grounded for long time instead of give me the punish I deserved for my wrong behavior,he realized my interest in been a ham operator,so he told me he was going to teach me everything about theory and practice to pass a ham test and after 3 months I was ready to make the test which I passed easily. Country regulations didn't let kids below 18 to own a ham licence and I had to be granted only the "second operator class" licence. I spent five years operating his station as CO2DR mainly in cw he sent me to a morse code academy for 3 months to learn it and I graduated at 25 wpm speed.I am glad he did it otherwise today I would not be a QSK operator,I can still receive by ears 60 wpm and send with my fist up to 50 wpm with this Vibroplex paddle. So,when I celebrated my 18 years of age I got my first "second class" ham licence with call CM2HB operating at my father's home working more than 200 countries from all over the world and wining several awards,like the AJD from Japan,all Russian republics,etc. In 1971 after married with my first wife (RIP) moved to eastern Habana and this was my very first AM/CW station.
The receiver at the left was a second world war Marconi with 22 tubes,very stable and good for cw.The TX at the center of the table was a second world war discontinued Aircraft Bendix radio with a pair of 807 tubes at the PA and another 807 as driver plus several 6SJ7 tubes as independent bands oscilators that I modified later and replaced the finals for 6146 and built inside a carrier control modulador with 12AX7 and a 6DE7.The small box between radio and mic with a handle on the top was my homemade electronic keyer using two russian tubes and even the paddle I am using at that moment was home made as well. And underneath the table you can see also the home made as well power supply to feed the Bendix Tx. I was born at Habana,Cuba business for 25 years for different government enterprises.In 1991 looking for a better quality of life I emigrated to the states two way radio Trunking system . In 1997 I became proudly american citizen. For many years I have been a member of the well as technical ragchewing with my friends about by first time the stations W2ONV (SK) and NU9N (www.nu9n.com) on the freq of 14178. I am active in the 40 to 10 meter bands on SSB, CW, PSK-31 and RTTY.. As part of my hobby I am the QSL manager If you have contacted any of these stations and need their QSL card,don't forget to include with your card the self addressed stamped envelope if you are within the states but if you are in other country,please don't send me IRC's,they are useless,just send me the proper amount of $USD to cover the expenses. I want to make myself clear on this matter,If you are a serious dx'er you are comitted to send me as I said before the SAE envelope with the proper stamp. My present station is a K3
If you want to know more about the K3,click on this link : http://elecraftk3.blogspot.com/2009/11/testing-blog.html its my blog where you can read all the information I have found at the net abou it.Thanks My mic is an AKG D88S My analog PS is an Alinco DM-340MV 35A PalStar AT1KP 1.2KW antenna tuner Ameritron AL-80B amp that uses a single 3-500Z tube see the users review: http://www.eham.net/reviews/detail/448 Also my backup radio from the same company is a K2 with its own automatic antenna tuner that sometimes I use when travelling far installed at my mobile,as well as at Field days,camping,picnics,etc see the users review: http://www.eham.net/reviews/detail/2357
My antennas are a Cushcraft AV3 vertical at only 20 feet up for 20/15/10m and a half wave lenght dipole for 40m at low high (20 feet) because of rough HOA local regulations.
I operate in my Kia Sportage 2009 the county FM VHF/UHF repeaters with a Yaesu FT-7800.
I am the control operator of the AD4C UHF repeater(second cabinet from right to left)
covering the whole palm beach county, this machine is at 500 feet high on a comercial tower as this one you see here by south east FL and pass by here,feel free to give me a call on it. Visit my own webpage clicking in the link provided at the begining of this biography and enjoy it. I thank God everyday for the blessing of being a Ham operator and for giving me the best time of my life making good friends from all over the world. I'm fascinated with this hobby and the decent people who are engaged in Other interest include digital photography with my 7.2 megapixels Kodak Z-712 IS. God Bless America and all the world hams. Thanks for stopping by. See you on the bands. And remember life is too short to be upset fighting each others ,live it happily as I am always laughing and dancing the "lambada".

,so they both figured out that was me,that evening when he arrived home
,my old man who always has been the best dad in the world and who always had all the patience with me and my brother
to develop my code skills by his advice,before the ham test 
that I kept for many years still
where I graduated as Telecom Technician and worked on two way radio 
where I work as well as electronic technician for the government maintaning a Motorola 800 Mhz
and my main goal in this hobby is DX chasing either on SSB or CW as
that got my attention five years ago when I listened 
of the following cuban stations:
with a freq of 444.325 and PL tone of 179 Hz,if you happen to be traveling 
and good DX's
