SN 6688 lives!
Locked
 
|
Hello all!
I am proud to say that K2 sn 6688 is alive and well in Hutchinson, KS, USA I finished up all of the preliminary testing and alignment, then built the option boards (DSP, SSB, NB, 60mtr, 160mtr). A few minutes ago I did some over-the-air checks on 40mtrs with a friend across town. All sounded good to him, so needless to say I am pleased. There was one glitch though, we shifted up to 28.400, and my audio level dropped way off. I had to practically yell in the mike for my friend to hear me. Is this a common thing that 10mtrs needs more punch or do I have a problem? Any ideas on what I might be able to do? I saw something in the manual about changing r15 on the SSB board, but I think that only applies to SSBA level 1, I was set at SSBA level 3, SSBC 1-1. When I received the "box 'o parts" I was a bit intimidated. After perusing the manual I was put very much at ease and pressed on. The manual was so well written I think that anyone with an appropriate soldering iron could put it together. The biggest thrill I have is when I tackle a project, be it for work where I do building automation programming, or building a kit like this, is when you are finished and it all works as you expect. What a wonderful project this has been! 73 de Allen, W1SBY ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[hidden email] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html

Allan,
Set the 10 meter bandpass filter to peak on 28400 rather than the 28200 suggested in the manual and you will likely have more 10 meter coverage. Note that the 10 meter band specification for the K2 is from 28.0 to 28.8 MHz, so do expect output to fall off above that frequency. 73, Don W3FPR Allen Wisbey wrote: > Hello all! > > I am proud to say that K2 sn 6688 is alive and well in Hutchinson, KS, USA > > I finished up all of the preliminary testing and alignment, then built > the option boards (DSP, SSB, NB, 60mtr, 160mtr). > > A few minutes ago I did some over-the-air checks on 40mtrs with a friend > across town.

Allan,
I forgot to mention - after you adjust the 10 meter bandpass, then adjust the 12 meter capacitors too - the proper setting depends on the setting of the inductors which will be changed if you re-peak 10 meters. 73, Don W3FPR Allen Wisbey wrote: > Hello all! > > I am proud to say that K2 sn 6688 is alive and well in Hutchinson, KS, USA > > I finished up all of the preliminary testing and alignment, then built > the option boards (DSP, SSB, NB, 60mtr, 160mtr). > > A few minutes ago I did some over-the-air checks on 40mtrs with a friend > across town.

That's great Allen! I'm in Goddard about 45 miles SW of you - nice to have another K2 in the area.
