Hi there;
You have got a T300 Narrowband
repeater (12.5 KHz Channel spacing). The IF Filter that you have is for 7.5 KHz
bandwidth rather than 15 KHz (Which is for 25 KHz Channel spacing).
Unfortunately you have the last
of the T355 receiver's and these were double conversion with 21.4 MHz IF's
compared to the 10.7 MHz IF's.
I may be in a position to get
you some 25 KHz T300's as I am aware of some that are being replaced by T800
repeaters if you are interested.
We used to go the other way with
the older gear and whip in a xtal filter from the old Pye/Philips P135 Falcons
to narrowband the RX modules and change some R and C on the food
chain.
I've grown up with these in NZ
so if you need any help dont hesitate to give me a holler :-)
