[Premium-Rx] Cathodeon Crystal Filters

[Errico Prota]

Hi Fellows!

I have these professional crystal filters. All are like new (never used)

1) 35,4 MHz Cathodeon - England BP 4772-00  (1° IF filter Band Pass 8,50 
kHz symmetric)

2) 1,4 MHz Cathodeon - England BP 4701-00 ( Bandpass 6kHz symmetric) 
(good for AM-FM)

3) 1,4 MHz Cathodeon - England BP 4710-10 (Bandpass 600 Hz  symmetric)  
good for CW

I have also a crystal on 34.000 kHz for 1° IF oscillator (35,4 MHz - 34 MHz = 1,4 MHz for 2° IF...)



If interested and for any info, please let me know off-list (eprota_at_tiscali.it)
