[App_rpt-users] uri to msf5000 interface - ever done one?

[Eric Guth]

I found this on batboard and kept it in my file.  FYI.
Connect URI to MSF5000

CODE: SELECT ALL
MSF SSCB---------URI
TP9 (Mic PTT)------1
TP8 (Mic Audio)---22
TP3 (Disc Audio)--21
TP7 (Ground)------13


Passes audio and CTCSS just fine. This was for a setup where the URI was handling CTCSS
encode/decode and TX qualification so no COR signal was necessary. I set the receiver qualification
to "ON" in the MSF Channel programming and set my PTT priority to "L".

not enough tx audio problem ive been having.

i cant get anymore than 1.1khz max dieviation out of it using the uri.
if i use the uri amplifier to boost the audio , i get somewhere around 2.5khz, i am able to her that it is clearly distorted and choppy audio.

so , ive got a digital capable uhf r2 msf5000. it worked great as a stand alone ham band repeater on 442.925 and the audio - everything was fine using its own controller.

so i changed the codeplug to what some guy WA1??? on repeater-builder recommended for the settings for using an external controller. because i want the allstar box to control the whole box. i preferred dsp for audio.

i soldered to the TP2 ,3,4,and TP9 test point to get my audio and everything else. i want to use those because it said the tp for reciever audio is pre-emphasis. so all the wires go to one area and then all my connections are soldered to the corresponding TestPoint connectors.

so i tried making a interface cable to the j2 side mount plug (the 25pin on the side of the station) same result on audio. i used line 2+ and line 4+ for the audio. With the audio maxed out -still 1.1 khz coming out with no audio amp and about 2.6khz and distorted and choppy coming out with the audio amp.

anything come to mind?

 i hope to get this figured out , so i can interface the next msf. where did y'all interface your uri's to an msf?

thanks so much ,
