Christmas 07

	K4CHE 2007 Alexanderson Alternater Christmas Eve Reception SAQ Attempt. ( The attempt was not successful.) Suggestions welcome. Many Thanks to Al, N3FRQ for his assistance and dragging me down into the lower frequencies. Information on the Alexanderson Alternator and Al's reception of SAQ can be found on K2TQN's(John Dilk's) home page: http://www.eht.com:80/oldradio/awa/events/grimeton/grimeton.htm Addtional info on the Anderson Alternator by VE3FAB can also be found at: http://jproc.ca:80/radiostor/aalt.html
	The loop that will be used for the Alexanderson Alternator attempt has sides that are 8 feet long and the loop consists of 12 turns of wire--The turns are wide spaced to reduce capacitance as the loop was designed for 500-200 Kcs. A separate pick up loop was utilized consisting of a single turn and for matching to 50 ohm coax. A small rotor was installed below the center section.
	Remote tuning with a screw driver motor.
	Very important--- only use a Rolaids Bottle to house the motor , no other brand of antacid will work.

	\| A Capacitor decade box and a fixed capacitor of .1uF were added this month to resonant the loop on 17.2 Kcs. The decade capacitors pad the loop down and you still make small peaking adjustments with the variable.
	VLF receiver. Tunes 10-30 Kcs in .1 or .05 Kcs increments. The receiver also has a fixed tuned channel on 60 Kcs. The set has two filters, 200 cycles and 50 cycles. The final IF is 1Kc which feeds an audio amplifier. So you get to listen to the 1 Kc IF. Its amazing what you can find at hamfests.
