Wrote: In 2007, Gary Gitzen and I came up with a Carrier circuit mod thatallows retrofit with most 1mA meters. (It can also drive an 18-ohm unit should you find one later.)  I think it's in the mailing list archive andthe Pearls, but it did not make it into Y2K-R3. I have the write-up on my hard drive. When I asked for circuits for the R2 revision that mod wasn't submitted to me. I certainly would have included it. Please email me a copy of the circuit and your notes. I will write it up.

No.  I just turned 75 the other day and personal responsibilities make any such projects impossible.
I have a number of partially done large articles that would benefit the list if one wanted to volunteer.  Some will take over 100 hours to bring to completion.  Contact me off list if you're willing to do some self-flagellation for the greater good. your only reward will be that you contributed something to the list. You also will be second guest and criticized by a number of lurkers whose only joy is shitting on others contributions.
Tisha Hays said she would take over the task for a R3 supplement.  There is much new data that should be in there including the newer painting articles.
I have a number of miscellaneous articles which I've offered to the list over the years. A number are copied tutorials related to radios but aren't R390 or *A* specific but can be a spring board for ideas. Some are *in progress* and need finishing.
Al has agreed to add them to the R390 FAQ site site so they don't get lost in 404 land.
