H'mm that seems a bit off. Normally, fire control sets search at a lower PRF, then
track at a higher one. FWIW, the first available site I could find credits Fan
Song C/E with the following PRFs:

PRF 828-1440 Search. 1656-2880 Trk.

Makes me wonder now. Did they "flip a switch" and double the prf? Or
did the prf double because the aircraft was in the box and two beams
at the same prf were hitting?

I imagine PRF changed automatically as soon as they started auto-tracking. Otherwise,
they could do so manually when jamming required manual track. The Fansong actually had
three guys to do manual tracking, one each for range, altitude and azimuth.
