NO, as all the actual dated original documents that have been presented here have shown, the 343 line field test was NEVER at 3.25MHz carrier spacing. The RF Alignment manual I copied showed they were aligning the 343 line RR-359 sets to 2.25MHz in November of 1936. I fail to understand your instance to the contrary without ever providing a single piece of original documentation of support.

I went back to read the Joffieffe presentation to the FCC on June 15, 1936. In it Jollieffe asserts a resolution around 440 lines and the need for a 6 MHz channel. However he explains that the construction of the transmitter for the July 1936 first television demonstration was 343 line and a 2.25MHz carrier spacing.
So the impeding move to 441 line was pending, I have not found a date for it's first public demonstration but i suspect it must have been late 1936 or early 1937.
So for the record, I fully agree with your statement and appreciate your dilligent clarification.
