Ron,
Does the receiver work on all bands? You can tell even if there are no
signals available - turn the gain up to the point where you can hear a
bit of noise with no antenna connected. Then connect an antenna - if the
noise level increases, then the receiver is working. It may or may not
be working well, but at least you can get a signal through it, and that
is one giant step.
If the receiver works on all bands, then you do not need a signal
generator - the transmit stages serve to provide the RF signal, and yes,
you do need to measure it. So you need an RF Probe. The parts required
to construct an RF Probe were included with your K2 kit.
Backing up a bit - if the receiver does not work, yes you will need a
signal generator of some sort to make troubleshooting easier. But first
try the K1 and K2 Cheap and Dirty Signal Tracing technique. Look on the
Elecraft website Builder's Resource page.
