[Elecraft] KX1 rehab

[bill - K7WXW]

Intent? Good question. Mostly I am wanting to tune the rig so it runs as it should but I also want to know how it works and learn how to do the stuff you mention in your list.

I am teaching myself how to do things like align a radio and checking specs.  As I haven't found anyone local with the time or interest in being a mentor, I am really happy to have email lists like this one!

Thanks and 73 de bill K7WXW

Hi Bill, 

  The question goes to intent. Do you intend to operate mostly, or do you intend to learn the radio inside and out? Yes, a new to the shack radio should be checked out. Doing that, can be done in a number of ways, depending on the intent. If you want to assure that it is working to specs... then a rx sens check, a spectogram sweep, power out, and tx waveform, with a monitor of current consumed, could be accomplished without disturbing the radio or risking delving into the internals. Not too time consuming either. 

  On the other hand, delving into the radio, finding out how it works, and what all goes on when signals happen, tx and rx.. then go thru the entire setup in the manual. Be aware of required test equipment to accomplish that. Takes a bit longer.. but you learn a lot too. 

 Good Luck, 



Have a great day,

Bill,

If it appears to be working to specs, I would leave it alone.  You may wish to see if spreading or squeezing toroid windings in the output results in increased power output, and/or change the resistors in the output (as pointed out  in Elecraft addendums).

Again if it ain't broke, don't fix it.

I haven't made a QSO with it yet but I have done some listening.  All the menus appear to behave as they are supposed to behave.

I also bought the internal ATU kit, which I built over the last couple of evenings. The ATU seems to work but I have a little more testing to do before I am sure.

Here's the question(s):  

Does it make sense to run through the test and alignment procedures that one would do while building the kit? 

Is there a list somewhere of tweaks and things to be aware of, especially with regard to power output, filtering or key clicks? 

I have seen a random post or two about adjusting coils and the like. Thanks in advance!
