KGO was on 780 (384.4 m) for just over a year - 6/15/27 to 11/11/28 - at 
which time GE moved KGO to 790, where WGY was already operating. Both 
stations operated on 790 until NARBA, then were moved by table to 810. 
KGO remained (nominally) ND-U at 7500 watts with the longwire until the 
completion of the three-tower DA at Fremont in 1947, at which point it 
became 50 kW DA-1.

So the "breakdown" of WGY's de-facto I-A status actually predates the 
initial designation of the I-A clears, if I'm not mistaken, and almost 
certainly could not have happened without the active cooperation of GE - 
surely it was more valuable to them to have a I-B in Schenectady and a 
I-B in Oakland than to have a I-A in Schenectady and a regional Class 
III in Oakland. (Though presumably I-A status in Schenectady would have 
prevented the postwar drop-in of KCMO Kansas City as a 50/5 kW II-B on 
810, at least until the breakdown of the clears many decades later.)

As for Denver, the breakdown of KOA's I-A operation indeed came after 
NARBA, when several of the daytimers that had also moved by table from 
830 to 850 upgraded to fulltime operation (most notably Boston's WHDH, 
but also Norfolk.)

The old 780 kc channel was never a class I - it was the regional channel 
belonging to KEHE/KECA in Los Angeles, WMC in Memphis, WTAR in Norfolk 
VA, etc., all of which moved to 790 by table.
