Thanks for the post. I've been putting together one of these transverters in
kit form, so it's good to see the info.

Whether it's you or someone else, I would love to see a ground-up,
well-documented design of a great-performing transverter, including design
decisions (what you did, what you didn't do, and why), math to describe how
appropriate passive components, filters, matching, etc., were defined, how it
was assembled, tested, and aligned, etc. In fact I suspect people would pay
money for a good design booklet that walked through this. I know I would. And
isn't learning and experimentation supposedly what ham radio is about,
especially at VHF+? All the better if you make schematics and board artwork
available using some cheaply-available EDA package like Eagle or KiCAD.
A few people (W1GHZ and a couple others) take many steps down this path, but
the information superhighway is littered with examples of "here's a design I
pulled out of thin air, feel free to duplicate it, once you've found all the
critical, obsolete parts" or else "here's a rough sketch I made of a
transverter, and since you're all veteran RF engineers you'll know what to do
from here."
It seems like this would be instrumental for VHF/UHF newbies, not just from a
theoretical perspective, but just a getting-on-the-air perspective.
