Hi Pete,
K2 is a QRP rig and can deliver output power at around 0.5 watt. Itself
has already been a nice RF signal generator. Turn your K2 power knot fully
counterclockwise. Press and hold 'tune' and read the SWR on the W1 over
the tuning range. Due to the lower power output from K2, interference to
other Ham stations is minimal.
Unlike the LP100, W1 is not a vector watt meter. It can only give you
reading of SWR and Power.
In the past, I have several times in this reflector mentioned that a
transcevier with TCXO or stable frequency output has already been a very
good RF source. The trick is to use a good RF attenuator or directional
coupler to lower the output level. Now AT1, CP1 could be choices.
I finish the construction of AT1 which is a piece of cake. Unlike the
usual attenuator obtained from the market, AT1 can tolerate 2 watts RF
power. If you combine K2 with AT1, the whole will be a nice RF signal
source. Of course, don't forget to turn the RF power knot fully
counterclockwise.

It would seem like you could combine the W1 with a small DDS based sig gen
for a very compact basic antenna analyzer. Is it sensitive enough on the
lowest scale to do that?
Just thinkin....
