RE: [Elecraft] KX1 power mod?
Wait until you have the KXB3080 option installed and tested. Then check with a 12 volt power supply to see if you have 3 watts output on all bands. If less than 3 watts, install the power mod. Do not install the power mod if you have at least 3 watts output on all bands, it may overstress the output components by attempting to increase the power output. 73, Don W3FPR -Original Message- Hello all. I received KX1 SN 1721 several days ago. As of this evening, I have successfully completed Part 1 - both assembly and testing! I'm having a lot of fun with it, and looking forward to many fruitful hours of operation. Anyway, my question: I am building the 80/30 module to install from the beginning. Should I make the power mod now (it would be a whole lot easier than doing it later), or am I better off leaving it as is until it is completed so I can confirm low power out?

[Elecraft] KX1 Power Mod
Folks, Up until today I had beilived that the KX1 power mod was needed for the KBX3080 install and desirable for others. NOT SO! I now have Wayne's input on the subject, and find that it is to be used ONLY if your KX1 actually does have low power output. If you can develop at least 3 watts on all bands with a 12 volt power supply, do not install the power mod. (the spec is 3-4 watts with a 12 volt supply - so if you get 3 watts or more that is all you should expect). Running the KX1 at incresed power output stresses the components unnecessarily. Over 4 watts is not a good thing. I realize that hams try to squeeze every extra microwatt out of the transmtter, but ask yourself if it is worth the increased probability for failure of your KX1. 73, Don W3FPR -- No virus found in this outgoing message.

RE: [Elecraft] KX1 power mod
Joe, The 'KX1 power mod' is available from Elecraft as PN E850230. I could not find it on the website, and I really don't know why. The change is quite easy - just 2 resistors to change. R30 increases to 33 ohms (from 22) and R11 is decreased to 4.7 ohms (from 10). If you have the 1/4 watt resistors, you can make the change. Someone who had excess offered them on the reflector a day or two ago. The change is needed for the KXB3080 installation, and has been shipped with that option, but it can be installed on any KX1, even though it is not required. Do not exceed 4 watts for any significant length of time with your KX1, and keep a watch on the temperature above the tuning knob if you are operating at higher power levels. 73, Don W3FPR -Original Message- I've recently seen reference to a KX1 power modwhere can I find this mod and what version of the KX1 is it used on??

Re: [Elecraft] KX1 power mod
Here's the link to the KX1 Power Mod on the Elecraft website. I searched for it also and couldn't find it. So I tried a Google search, and there it was - very well hidden. Don't know why it isn't easier to find along with the other Elecraft mods. http://www.elecraft.com/manual/E740099%20KX1%20Application%20Note%20Rev%20A.pdf 72/73, ed - k9ew On 11/8/06, Joseph Trombino Jr [EMAIL PROTECTED] wrote: I've recently seen reference to a KX1 power modwhere can I find this mod and what version of the KX1 is it used on??
