[App_rpt-users] Setting Up a Remote Base w/RTCM

[KD8USF]

The reason why you are seeing the pulse go over the link is because when the link radio unkeys it hears the repeater tail and therefore keys up the link again. I also run an MSF5000, it does the CWID with no PL which keeps the ID off the link unless someone kerchunks the repeater while it's ID'ing. One way to stop the pulsing would be to set no tail on the repeater, but if you're like me I have at least a 2 sec tail because I don't want the repeater going up and down all the time like a simplex radio, and with no tail you would not hear the repeater come back to you when you keyed it up.Andrew.

Our remote base isn’t cutting it. It is half-duplex using a Vertex VX-4200. We are told that the audio has no bottom, it is sending CWID that it hears from the repeater (I knew why) and is sending pulses. I didn’t set the hardware or software up, so as I ask please know that I am at the top of a mountain and the remote base at the bottom where we have internet. Here’s what we are dealing with. Our intent is to attach the RTCM at the repeater site once we have internet up there. Until then... The DB-15 on the back of the Vertex VX-4200 is *almost* capable of being used as a repeater controller output. Pin 1 = TX AudioPin 2 = RX AudioPin 6 = External PTTPin 9 = COR (see notes)Pin 15 = GRND COR is achieved by creating voltage divider using other pins. Only then will one get COR but not COS. PL will only make it to the speaker on the front panel and rear jack. PL IS NOT on pin 2. Pin 2 is squelched but when it receives the repeater’s built-in controller (a Motorola MSF-5000). Every time our CWID goes off our remote base sends it to everyone. Here are the problems. First, we’re told that we are committing link abuse by “jumping” or key clicking every time someone else transmits on a node our node replies. I don’t know what I am talking bout at this point. :-) Next I am told that our audio has no bottom end. No bass. The pin that we’re able to pull from is the only source that we’re aware of and is the pin used by Vertex to send audio to their VRS (mobile repeater). http://www.shercoares.org/doc_files/manuals/vx4200_sm.pdf I’ve been told to turn PL off and let the repeater pass through the tone. But please remember that pin 2 has no PL on it. Only the front panel speaker and rear speaker jack audio are muted by PL. The easiest solution may be a GM300 but I cannot get the darn software on our old 386 laptop. The floppy decided to only read those created by itself. We’re puckered up on this one. Suggestions are appeciated.
