[Elecraft] Help a Blind guy sell his gear?

I have 2 questions. I happen to be blind and have some great gear I just don’t/can’t use. Used precisely 3 times. First question is where is the best place to list my used Elecraft gear? Also, I’m having trouble learning what is a “fair” price. I don’t want to take advantage of anyone…and I don’t want to give it away either. I need the money to invest in my music gear. Here’s what I have. KX2 w/tuner and clock. AX1 &2. I have the bag for it as well as extra battery and MH3 mic. Additionally I have Chameleon MPAS Lite antenna and a backpack from Chameleon that holds everything, and room for a bunch more. I was thinking $1,500? Is that off? High or Low? Help! Thanks! 73 KO4NE

I think so. The mysterious R7 may have been left off of the final circuit board precisely to cause such a bad mismatch that it would be obvious to operator, software, or both, and so that corrective action could be taken.

> Hi Joachim , How are you adjusting the power in each of the three power settings. Do you have the coax and dummy load connected directly to the K3? Trade out the short jumper to the dummy load to assure yourself it is good. After that, I would measure power with an external calibrated wattmeter. The K3 utility is obviously not seeing the power it is looking for, low by .5 to 12 watts depending on the power setting.
