Tom: Don't get distraught! Realize that these kinds of problems are a
normal part of homebrewing. This is not plug-and-play radio. Just about
everything you build will have these kinds of problems -- problems that you
have to resolve before the device will work properly. And you can learn a
lot from these problems. The net is a tremendous resource for you in this
effort.

I have some articles on my efforts to resolve similar problems with HB
receivers.
Check out my web site and look in the HB/QRP and 17 meter sections.

Good Luck and FB on your HB project.
