[SignalOne] Filter Identification Question

[Bill Turini]

I was looking over my pile of filters last night and was wondering if
anyone knew the marking scheme for the Tyco filters?

I have four filters

1.
---

 ------------------------------------
| C-F Networks Division  Tyco, Inc.  |
| Model 8.815-1.2                    |
| 7004                               | 
 ------------------------------------

[blue case]

This is a 1.2 KHz wide filter. I assume the 7004 is a date code?


2.
---
 ---------------------
| Tyco Filters, Inc.  |
| P/N 001-6060        | 
| P/N 08-S0008-001    |   	(looks like the board #?)
| 7103                |
 ---------------------

[blue case]


3.
---

 -----------------------------------
| C-F Networks Division  Tyco, Inc. | 
| Model 8.8157-.4                   |  ( 400HZ? )
| 08-50004-001	                    |  ( Yes, 5. Looks like they screwed
up on board number?)
| 7004                              |
 -----------------------------------

[blue case]


4.
---

 ---------------------
| Tyco Filters, Inc.  |
| Model 8.815-.4      |     ( 400HZ?)
| 08-S0004-001        |
| 7251                |
 --------------------

[non-painted, i.e. silver color, case]


Anyone have any comments on the various colors or part numbers,
designations, etc?

I have a 400Hz CW filter in my CX7B that is quite a bit different from
the standard blue ones. The case is about 1" square and a little longer
than normal. I don't remember any markings at all on it.

73's
