Paul,

At this time during the sunspot cycle, and especially over a holiday weekend, you are not likely to hear many signals from a random wire unless you have some way of tuning it - that is doubly a problem if it is just strung out on the house floor. Being 70 feet long, it is likely presenting a high impedance at the end approaching 4000 ohms, where a lower impedance (ideally 50 ohms) is needed.

The TUNE buttons put the KX1 into transmit, but you should be operating into a 50 ohm load. Can you obtain or borrow a 50 ohm dummy load? That and some means of indicating power output is necessary.

For receive, a signal generator of some type is a real asset if you do not have a good resonant antenna with a 50 ohm feedline.

I suggest you contact some of the local hams who might have some test equipment and dummy loads to help you out.

73,

Hi folks.  I'm in the final steps for getting my KX1 working and am kind of 
stuck.  Since Elecraft is closed until Wednesday I thought I'd check with y'all 
for a few ideas before then.

Q1). What exactly is TUNE mode supposed to do? For me it doesn't appear to do 
anything.

BTW, I'm trying to align the thing and I have a random wire dipole fed directly 
to the antenna jack.  I have the KXAT1 ATU option assembled but it's not 
installed in the rig yet.
