The plug in board topic again:
I was looking in the Jameco catalog and found surface mount boards that allow you to mount and then plug a chip into another board. These are called "Surfboards" as in surface mount boards. Also they have a nice prototyping board that these small boards can plug into. Actually the prototyping board looks nice for a finished product if one wants a nice homebrew look when finished. But the price of the main board is a little too high to be used as the finished product and you would want to keep the board for other project needs. This I think would help you resolve you problem of a chip being on another board. Just go get the board, plug it in.]

I am working right now on placing a "spider web" vfo coil form and variable cap on the Colpits oscillator of the SR 40 V6. Using the Colpits oscillator on the board where the values of C5 and C6 are typical for most Colpits osc. After the dividers or DDS section divides the vfo 8x the effect of drift after warm up will be reduced by 8x also. Later I might add the GM4ZNX thermal drift compensation bridge circuit to the vfo. I will then use the V6 to tune the i.f. of my main receiver and I can tune back and forth a little to get the offset I want. Actually I plan to use a Varicap as the main tuning cap. I got enough parts and boards. The vfo is around 18.04 MHz and the i.f. I am tuning is 2.255 Mhz. I am going to add a 50 uA S Meter also. The S Meter will be reading a wide 12 kHz to 96 kHz i.f. but it can give me an idea of over all band energy at the PC location away from the main receiver. All in all it is a nice board and I can do things such as this with it as it is. It is a more user friendly board than I thought it would be. V7 also seems like something I might try also.
