Re: Reverse Burst Comments (Com Spec RB-1) If you add a circuit like the Com Spec RB-1 board to the typical repeater system using a ts-32/ts-54 board... the tx ctcss is not disabled or removed before the RB-1 delayed ptt line drops.
So you have the phase inverted ctcss present for at most up to 200 ms typical before the tx drop. If you don't remove the ctcss source the inverted ctcss remains up until the tx off/drop... Any of you actually running the RB-1 board with a true reverse burst type ctcss decoder (built into your radio)? Is a true reverse burst decoder in your commercial radio completely "fooled" by the phase inverted ctcss before carrier drop function. Or do you actually still hear some minor difference from the rb-1 type operation vs an original true Motorhead (Motorola) encoder - decoder operation? Thinking out-loud about having to possibly mute the ctcss at some time after invert and before the delayed ptt drop as a requirement to get the full/true reverse burst quiet squelch close. Any of you been down that road already? skipp
