Wiring/Programming for A reverse RF link to a repeater

I have obtained permission from the Rocky Mountain Radio League here in Denver to link an all-star node up to one of their repeaters mountain high.

I have a few questions to set up the best link to the nice nice repeaters up there @ 11,500 feet above sea

Already Solved Problems {

First Concern: Accidentally gets stuck on TX

Solution: Use the radios built in TOT

Second Concern: Transmitting random stuff that cant be controlled (maybe interference from someone hitting the node)

Solution: SSH and disable through the computer

}

My Questions {

FULL DUPLEX???

So with one radio I could have it TX and RX on separate frequencies. This would Be a nice SIMPLEX link. I would not need full duplex because it would just be doubling with the repeaters other people inputs making it yeah…

BUT…

What about the hang time? Yes, the RMRL repeaters have Very Very long tails, so I have asked them to turn off the TX tone right away, and they will do that so I don’t have to get their tone and their little courtesy tone.

So should I spend the extra work of getting a Duplexer or Diplexer or band reject or band pass filter (whichever one, IDK) WITH another radio or would it work just as well with a SimpleSimplexSetup.

Now to the software part, which I hope you guys will help with.

  1. I probably want to disable courtesy tones| Easy, just in the Conf file comment it out

  2. Station ID in morse

Now this is my question because I don’t want to break the law by not doing morse code, but I don’t want to annoy everybody by having the code in the repeater on the mountain as well as in the radio, because that would be a lot of stuff going on.

Maybe… Could I make it so there is no TONE transmitted when it does the CW ID? So it is just a “LOCAL” Identification

Thanks for any help anyone, it is all appreciated. I actually did not exect approval, but I want to carry on now that it is approved.

Sorry for all the people who are not fans of using the input frequency to InternetLink, it works Great for the other repeaters that do it, nothing bad has happened for the year I have been a ham.

So any ideas, tips, don’t do’s etc? Thanks for any advice!!!

I am having problems understanding what is going on with the RXONDELAY command in

duplex=1 mode. (simplex with telementry )

From what I understand, this command turns off the reciever for a value of 20ms times (x) (my value 75) after the transmitting is dropped to prevent ping ponging or relay racing.

Once this value is reached, should not the receiver come back on??? I find that this value will play a part when a valid signal comes back on as well. The usbradio will wait that (X) before

turning on the receiver even after the transmitting has already reached value of (X).

So, if the signal has dropped for over 5 second lets say, why would rxondelay play any part again??? Should not this value have to wait until the valid signal is dropped again???

I hope I have explained this correctly.
