RT-900 CTCSS Decoding Window
Added 2025-05-25 08:48:06 +0000 UTCTesting here with my local repeater CTCSS=71.9 430.91250 MHz Signal S5
With XTAL 671 = +0, patchy, sometimes decodes sometimes not, right at the edge of the window.
With XTAL 671 = +80 , this represents roughly 500 Hz adjustment, repeater comes in fine, no cutting out.
With XTAL 671 = +150, it begins to be patchy again, decoding sometimes, sometimes not, so it's now at the other edge of the decode window.
XTAL671=150 at 430.91250 representsa bout 1 kHz decode window. That is absolutely HUGE. Repeaters should not be over 1 kHz off frequency, and if they are they have no business operating like that.
