I see what the lad wants to do. Ping pong is the non-descript term for the action happening during the repeater hang time. Skyler- The wise guys have spoken, with their knowledge still mentally lingering, I am going to throw this tid bit in there too: Unless you have technical control of the repeaters, you are going to experience the un-desired ping-pong action you are having -BECAUSE- what I said in my first statement.. For an ASL remote base to a repeater, one we had control of, at the repeater side, the repeater controller was set to only TX PL when the repeater's RX was active. That solved our ping pong issue. As I lead on to earlier, you are just going to have to deal with that as repeaters and their operation are created in the image of the owner - we are all unique.

Skyler, I think you seek a software fix for a electronics problem.
The pulse you are getting at rx/cor is from the switching of the TXer and I don't think a software delay is going to fix the issue.
Are you toggling the TX with a relay ? Did you put a zener across the coil of the relay if so ? You need to scope the source. Probably at the TX/PTT line / relay contacts, even a transistor may need changed/filtered with a cap. Is frame ground bonded with negative ? Should it be ? Check radio specs.
Things to think about.

I am dealing with a system (half duplex), which sends a pulse through the network. I've had this question quite a bit, but never been able to word it right. Hope this is understandable.
This "ping pong" issue only occurs after the transmitter is unkeyed. There is no way to fix this in hardware ( don't need to complicate it by going into technical details on how the link is setup)
RXONDELAY WORKS, but it is sort of pointless because now the beginning of everybody's transmission gets cut off, and is physically does not need to be.
We are really looking for
TX UNKEYS ------> Disable RX ------ > Wait 1/4 second ------> Enable RX
NOT RXONDELAY: USER KEYS ---> DISABLE RX ------> WAIT 1/4 Second -----> ENABLE RX
Is there any way to perform the function in mind? ( in either usbradio, or simpleusb). Has anybody here thought about this before?
Thank You, Skyler KDØWHB
