K2 Receiver issues

Bob-24
Greetings,
I just finished building my K2 and seems to work pretty well except
that it does not received like I think it should.  I put it side by
side with my K1 and the K1 picked up signals better.  They were louder
and clearer on the K1 than the K2.  I have made about 3 passes through
the alignments and am comfortable with those. The S meter, when I am
listening to a strong signal, will barely come off the first bar. All
of the resistance and voltage checks along the build have come out
fine.  I am now deciding how to attack this issue and would appreciate
any suggestions anyone has.  I am going to be doing some of the
voltage checks from the back of the manual next week and also seeing
if I can find a 10 MHz crystal to make the signal generator to begin
that process.
Thanks in advance for any thoughts

72/73
Bob, AD7BP

Bob,

Yes, the best and easiest way to determine what is wrong is to do
Receiver Signal Tracing.  That should allow you to isolate the problem
to a single stage and armed with that information, we can likely help
better.

You do not need a 10 MHz crystal.  Any crystal frequency within the
tuning range of the K2 will do just as well.  The 10 MHz crystal is
suggested if you have no other - they are inexpensive and commonly
available from a number of sources.

You will also have to build up an RF Probe (or use a 'scope).  The parts
to build an RF Probe were included with your K2 kit.
