Hello again!
Well, it seems that my filter IS a CW filter, with correct bandwidth,
center frequency and impedance BUT larger than the one used in the HW-101.
It appears to be an earlier version, suitable for an SB-300 or other older
rigs. Filter data is:
HEATHKIT by Daystrom
Crystal Filter
Part No. 404-M202-P23
Cf 3395.4 kc Z IN-OUT 2k
400 CPS @ 6dB 2.5 kc @ 60dB
So, is there anybody who wants to swap this filter for the correct HW-101
filter?. I hope somebody needs the larger one for another Heathkit :-)!
Thanks and best regards.
JOSE
