[App_rpt-users] Audio detection circuit to generate 'COR'

Tue Oct 6 13:30:40 UTC 2015

Other than using a Pi 2, and the newer/cleaner 828 module, Doug's setup based on the 818 module is exactly what I will be trying. Thanks for the info!

 Steve,
 Be aware that those transmitters are dirty.
 There is a note about a module using the same RF circuit on Doug's HAMVIOP site.
 He suggests a filter. REQUIRED if you are going to drive a amp or even connect it to a antenna!

  Thanks. For my first full duplex repeater (for test/learning purposes) I am going with 2 of those modules and a 6 cavity duplexor (likely of the 'notch' variety). If it works out may put my Mirage BD-35 on the TX side before the duplexor and get ~16 watts for giggles.

 Thanks Steve! I'll look into that as well.

   Steve COR or actually RUS "Receiver Un Squelch" is available in that radio. You have to unsolder the shield to get to it.

  Well, it is a generic question - any radio without COR. The specific  model in my case is a UHF radio module model # SA-828U: http://www.alibaba.com/product-detail/1W-5km-distance-SA828-U-uhf_60092524887.html?spm=a2700.7724857.29.62.Xbg6c5    Steven Donegan

  That might work, I use it for packet. 
  What radio are you on?

   Does anyone have a circuit that will take  audio from a radio and generate a pseudo COR signal for the  URI-x? If so would you share the  circuit diagram?
