Next year 1966, an improved QRC-160-1 pod was fielded in Vietnam.
The QRC-160-1A (QRC means Quick Reaction Capability) introduced the Modulated Noise Jamming technique against the SA-75MK Dvina (SA-2B/F) fire control radar.
Keeping the QRC-160-1 D/E band 4pcs Voltage Tuned Magnetron's (providing 100W FMCW jamming per magnetron), this pod introduced AM noise on the 6th~8th (96~128Hz) harmonic of the Dvina fire control radar's scanning frequency (16Hz).
At the Dvina scope, this technique resulted 6~8 vertical noise strobe, per plane.
In case of a 4 ship formation, 24~32 vertical noise strobe could completely confuse, or blink the operators...
... causing longer target acquisition, and giving the Weasels more opportunities.
