Was the RACAL 17 the first HF receiver with a VHF first IF?

HQ-100 is one I recall,  used the Q multiplier as the BFO.  I think the
HQ-100A had a seperate BFO and the Q-multiplier. I don't remember if they
seemed more effective than the crystal phasing on an SX-110 now or not. They
were both after the same market about 1959.
