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
