Hello all !
I am working on improving the performance of an FM Broadcast Translator that
is using a Remec Wacom BPBR filter in its output.
The three cavity filter is model WP-715D-3, it is serial number 4515. It is
set to pass 95.8 - 96.0, and to reject 95.4 - 95.6.
The translator receives on 95.5; it transmits on 95.9. (Ouch ! Close
spacing!)
The filter exhibits about 6 to 7 dB loss on-channel.
Would anyone have catalogue info or a data sheet on this item? I sent an
email to the manufacturer (sales at txrx.com) which was the only email address
I could find, and have received no answer after a week or so. I understand
that TXRX is the successor-in-interest to Wacom, but perhaps I am mistaken
and someone can correct me.
Could some kind person please tell me if what I'm experiencing (waaaaay more
on-channel loss than I'd like) is what I should expect from this unit?
Thanks very, very much !
