R-390 Family History Categories, 9/9/2022
In order to make it easier for you to find some particular
information of interest to you, I've divided it up into sections.
I'm open to suggestions, but thought some might be: VFO, Filters,
Adler, Cosmos, R-392, etc. I'd like to keep the number of sections
from growing too much, though. If 'final' is in the 'Last update'
column, it means I'm not planning updates to it. Please let me know
any suggestions for content and contributions welcome, Larry Haney,
Larry41gm 'at' gmail 'dot' com. Thanks.
