With 500-kHz crystal, output can be used as 5-kHz markers in sweep alignment procedure If SN7490P decade dividers are omitted and 455-kHz crystal is chosen, TTL circuit can be used to supply low IF value used by some receivers Circuit will oscillate up to several megahertz-J Carr, VHF FM Receiver Alignment Techniques, Ham Radio, Aug 1975,p14-22.
