[SignalOne] CX11A filter questions.

[Dr. J. R. Sheller]

I now again have a CX11A . SN10649701..I am going thru it and installing 
all of Paul's mods.  At this point I have some questions.  The 
schematics all show FL1 as the  small almost square unit.. FL2 and FL3 
as the units mounted flat on the outside edge of A8, the IF board.  FL4 
should be the CW2 filter mounted on the bracket above FL1, and  FL5  
would the CW3 filter mounted on the bracket above FL2.

I assumed that FL2 and FL3..because they were indentical .. would be 
cascaded.. according to the schematics, they are not.  FL1 and FL2 are 
cascaded in  AM, USB and LSB. while FL1 and FL3 are cascaded in CW1... I 
must getting dense n my old age, but this does not make sense to me.  
Can somebody explain?

My unit had both a 400hz Blue Tyco and a 300hz Silver color unit made by 
Crystal D???????.
The ink is smeared and cannot read the entire name.  The 400hz unit is 
installed in CW3 and the 300hz unit is in position CW2.  I would think 
this is backward.  My unit has the IF amp installed..it appears factory, 
but it is installed on the CW2 filter [300 hz]..  Do both filters, the 
300 and 400 hz need an amp?..  I have laid out an amp board, but dont 
really want ot burn it and etch it if I dont need a second one.

Sorry to be so long winded, but this damn filter thing has me scratching 
my head.

The CX11A I had previously, did NOT have the multicolor screen front 
panel.. It might be my antique eyes, but I cannot read the yellow..  are 
they all like this or has mine faded?

Last question.. does any one have a source for some of the relays in the 
unit.  I have spent a week on the net and called about every company 
around looking for the following :"

MAGNECRAFT   W174DIP-1      EXT AMP SWITCHING RELAY

MAGNECRAFT   W172DIP-8      RCVR  TR RELAY

MAGNECRAFT   W102RMPCX-3   OUTPUT POWER T/R RELAY.
Either they did nit have them, or they had a 250-500 dollar minimum.

If these are not available, any one have subs for them?

Hope I can get some feedback on all the above.

Thanks

Doc  K8RR.
