Mike,

Yes, you should have full receiver capability (albiet only on 40 meters) at
Test and Alignment II stage.

Check your components and soldering carefully (at least 3 times) - and don't
forget to check for jumpers W1 and W6.
Then do some 'quick and dirty' troubleshooting - try connecting an antenna
to W6 - if you find signals there, try it at W1 - if you find signals at W6
but not W1, look at the T/R switch area for the problem.  If you find
signals at both W1 and W6 but not at the antenna jack, the problem is in the
Low Pass Filter area.

If you find no results from the tests above, then turn to page 9 of Appendix
E in your manual, build up the test oscillator shown there if you have no
adequate signal generator and proceed with the steps beginning on page 10
through page 12 (but not the transmitter parts).

73,
Don W3FPR
