Re: SX-110 Alignment Puzzle
I can't open deja vu on my cell phone. Most receivers with single crystal filters adjust the IF to the crystal frequency.? ?A very few,? like the Collins 51J series need to have an exact IF frequency due to the way the tuning is done but this is very rare.?? Despite the discussion about signal generator calibration and stability it should be possible to align a simple IF with a service grade generator.? The crystal establishes the frequency. Since the overall bandwidth of the IF is considerably wider than the crystal great precision is not necessary.?? In most cases the crystal stage will have input tuning, a loading adjustment to set broadest crystal bandwidth, and maybe a neutralizing adjustment to center the phasing notch.?? Some earlier receivers have essentially a fixed crystal bandwidth and fixed phasing adjustment.? These use the original Lamb circuit.? The adjustment procedure is rather different from the later Hammarlund type filter.? Can be confusing but I don't think the earlier filter was used after aboutb1950.

Hi Steve again I believe from previous posts re the sx-110, you are trying to understand and implement the original instructions,? rather than use newer? techniques.

In the next step? I think it means the exact frequency of the that specific ztal in that specific circuit. I can only guess that for an older generator, you can adjust the frequency in small increments, but the readout of frequency is limited, so it will be hard to “dial it in”, so I think their intent is keep the generator setting from step 2 , and use it [don’t change it] to begin step 3 ?since step 3 is so sharp… just my guess. ? From some of my readings, step 2 cannot easily produce an “exact” frequency, at least with equipment of the time.? ? As I read your attachment , I can only assume that IF you are using the Original crystal , the factory has set step 2 .. so it is not really necessary to repeat it; but if you change crystals [your situation?]? you should do step 2?

The IF alignment procedure as spelled out in the SX-110’s Operating and Service Manual is a little confusing in one spot (see attached). In step 2 you adjust the top slug of the first IF transformer (alignment point "A") for a dip on your output meter (a VTVM, usually) (while varying the generator frequency some) – and the factory note says indicates that this alignment is to the frequency of the crystal. Fine -- I've found that null and know the frequency of that exact point.

Hi Joe,
I have a

I can no longer afford the space or time to use them. I have previously operated most if not all of the items. I know some of them worked, but I don't remember which. The rest may or may not have worked. Consider all of them not working, so your only surprise will be most work. The physical condition of all items are very nice. I am including a couple of pictures. Additional pictures would be difficult to get. I can no longer safely lift most of the pieces to allow more photos. Manuals are included for most items.
?
Consider this as a complete collection purchase. I am selling these as one lot, all 16 pieces in one sale. Items must be picked up in Ellettsville, IN. and must be removed from my basement (temperature and humidity controlled area). Most items are heavy and bulky.

The price is $3,850.00 cash or cashiers check. No PayPal.

I originally listed this as a package deal only. It was suggested to me that it would be difficult to load and transport all units at once. In case there is still someone who might be interested in the whole lot, I will sell as a package deal for $3,200 or best offer.
