Title: New/old project
Post by: Ed KG6UTS on July 11, 2018, 06:24:37 PM
Hauled home a 1938 home brew with enuf parts to make it live. Am documenting the wiring as it is before tearing it all down, 1940 Thordarson manual will be my reference.  The little mod scope appears to be a National CRR or close. Anyone know this or have documents?? Thanks!
