Preselectors
============

992E-1		Rack mounted for user with the 651 Receiver (or 851 Receiver if you make your cable).
		Often used with the 671U-4A Receiver-Exciter (see wiring information to make your own cable)
        	Requires an external source of 28 VDC (< 1 amp)
		Uses the 635U-2 preselector inside the housing. 
		We use our unit with the HF-8054A receiver and with a DC supply that powers the preselector and the
		the outdoor magnetic loop antenna (a Hermes). 
		You can download the manual here on the 992E-1 Shelf. Here is the Service Manual

635U-1		To be added

635U-2		To be added (we have three of them but no technical documents - all work which is good)
		Rockwell Collins Part number: 622 0402 009 and the FSC number is 5915-01050-13738
		There is also a 622-0402-001 and a 002 version. We are unaware of the differences.

		Power: 100/115/215/230 V 47-63 Hz. 5.3x19x24, 32 lbs 
                This unit was also replaced with a fully digital one - the PR-2025 (also a break in the numbering).
