455 kHz CW filter for ICOM

455 kHz CW filter for ICOM

Hi,

I have an ICOM 707 transceiver which uses 455 kHz filters (FL-52A and
FL-53A). I would like to add a CW filter, but ICOM's filters are
pretty expensive. I wonder if I could use a 455 kHz filter for a
different radio instead. Some mechanical adapation will be necessary,
but will they be electrically compatible?

I've found the following link:
http://www.qrpproject.de/UK/inradfilt.htm. Here, an alternative filter
is suggested for both YAESU FT817 and ICOM IC703. The ICOM uses the
same filters as mine, so this would suggest that filters for the YAESU
might work in ICOM.
