I have recently been monitoring NORAD freqs here in the SF Bay Area. On several occasions an aircraft will call Big Foot (today on Blue7) and ask for a "modes & codes check". Big Foot responded "sweet, sweet". This sounds like the aircraft is asking for a transponder check and the reply is that it is normal. Is this correct? Also, has anyone heard any Combat Air Patrol (CAP) flights over the S F Bay Area lately? Thanks.
