relay volt drop

http://forum.allaboutcircuits.com – Hi all I've built the attached circuit... It's a timer - the 4020 counts the pulses from a 555 and shuts off a relay at the end of the time period. I'm using a 12v relay with a 120ohm coil in place of the smaller one supplied with the kit. It all works fine - however I measured the voltage across the coil just now, and it reads 9V, I'm running from a lab PSU at 12.1V. The relay seems to operate fine, although I haven't put a load on it yet. I figure the reverse polarity diode and PNP transistor should drop the voltage by 1.4 between them, but I have a 3V drop.... The BC328 should handle the c (Embedded)
