JRC crystal filter data

Optional JRC crystal filters are as follows:

JRC##         NDK##       Bandwidth/-6dB
======== =========== ===============
CFL-231     (YF455FM)     0.3 kHz
CFL-232     (YF455DQ)     0.5 kHz
CFL-233     (YF455DE)      1.0 kHz
CFL-218A   (YF455EBF)     1.8 kHz
CFL-251     (YF455EB)       2.4 kHz
CFL-316                         0.5 KHz (9 MHz IF)
CFL-317                         1.8 kHz (9 MHz IF)
CFL-318                         2.7 kHz (9 MHz IF) (Standard on JST-245)


These JRC filters are DC coupled.
Need 0.01 uF in series to fit with other (ICOM) receivers.

Murata 455 kHz filters
CFJ455K13      2.6 kHz
CFK455J         3.6 kHz
CFW455IT       5.1 kHz
CFU455G         9.5 kHz

ICOM crystal filter specifications

Finally, I compiled most of the popular ICOM crystal filters. These data based upon various ICOM service and operation manuals such as IC720, IC730, IC740, IC765, IC756.

FL-44A, FL-52A, FL-53A, FL-96
FL-222,FL-257,FL-100,FL-101,FL-102,FL-103,FL-223,FL-232,FL-272,
FL-32,FL-63,FL-33,FL-70,FL-45,FL-30,FL-80,FL-32,FL-34,

Getting an IC-7000, 1

It's about time to replace the old IC-706 for more fun. I look up the QST review of IC-7000.
