Ted, thanks for posting that bfo calabration. Looks very similar to the old R388 instructions used by myself back in the early '70's. Somewhat tedious but always checked out against primary standards maintained by our second order calibration vans. Their standards were maintained by our Barstow,Ca. Repair & standard's depot.
This always makes me wonder how often we as hams check our "standards¡± like say a Bird meter or in my case, a TS-352 scraped by Barstow, then repaired by me and converted from BA-31's at 4.5 Volts each to common over-the-counter battery¡¯s for resistance measurement. Back then each item had a cal due date from the next senior shop.
Also, thanks to all of you for getting me back into repair and programming along with the Arduino world introduction,& safety, smt useage, tips about many other thinks like Linux, low power antennas, & QRP operation..
Frank, KJ5WI?
