    The plug-in concept was inspired by the National HRO-series receivers. Most multi-band receivers use a complicated rotary bandswitch, with lots of wires coming and going! Once installed, those things are impossible to fix or modify. My home-brew experience taught me that changes and modifications are always necessary. This project had to be easy to modify. The plug-in tuning units make it easier to work on. Also, each of the major sub-assemblies are on connectors, so they can be removed for changes. Even the front panel can be removed, and there is one big connector for everything on the panel.

    Always nice to see the work of another Cal Poly SLO graduate! I have a MCRP (Masters in City and Regional Planning) from Cal Poly. Lots of great engineers from the school as well - One of our local DOT engineers graduated from Cal Poly.

    I haven't been back to Cal Poly since spring of 1962.

    I understand the campus is quite different!

    No longer classes held in surplus WWII "Quonset Huts". with no A/C.

    I had a similar experience. I found some mini circuits TAK-3H mixers that were cheap. Of course, it's a 17 dbm mixer. Used them in both the transmitter and the receiver. Definitely scratched my head on that one! Thanks for posting your experience.
