[NLRS] MMT 28-144 Transverters?

[Dr. Gerald N. Johnson]

It can work.

Found a manual without schematic at: http://www.nx7u.net/MMT144-28.pdf
which says the receiver stages are double gate MOSFETs which will handle 
strong signals much better than the bipolar I presumed.

Has a schematic but it doesn't expand well.

http://www.g4fre.com/circuits.htm lists the schematic but has no link.

http://www.ko4bb.com/Manuals/08%29_Misc_Ham_Equipment/SSB_Electronic/MMT_28-144/MMT_28-144_Schematic.jpg 
has the schematic.

In my search I see Barry, VE4MA has been working on one.
