If the 50 uV signal generator indicates a signal level of around S9 on
your K2, that is exactly how it should be.
Your length of wire in the room may not receive signals well, depending
on the type of materials used to build your house it could be shielding
signals by quite a few dBs.

You won't be able to do the low power tests without either the jumper
or the PAIO board. The jumper was installed to make sure that you
could do the tests without doing the PA install AND to make sure that
