Nathan's 37-690X
#29

Next up is everybody's favorite part about these 37-XXX radios - the RF subchassis.  

Disconnect RF Subchassis

I went through and labeled each of the connection points to the RF subchassis and labeled each wire after desoldering it.
With my trusty letter wire markers I made it to letter T!

Freedom

I believe that I've read that the 37-116 and 37-690 share the RF subchassis. Note that the tuning condenser is actually stamped 37-116 on mine.

Finally, here it is with one of the sides removed to facilitate recapping:
