Hopefully those on the list can answer a few questions about getting app_rpt setup and what is really required.<br><br>1.&nbsp; why is the arib needed and what exactly does it do?<br><br>2.&nbsp; Why do I need 2 fxs ports for full duplex operation?&nbsp; my phone is full duplex when plugged into the same port why can't the audio for the radio be?&nbsp; Come to think of it I can buy a little phone with a headset jack for next to nothing and have seperate tx (mike) and rx (speaker) audio.&nbsp; this just takes a 2 to 4 wire hybrid common to most phones.&nbsp; why do I need the arib at all?
<br><br>3.&nbsp; Why do I need the arib at all?<br><br>4.&nbsp; is the rbi-1 really needed?&nbsp; what function does it serve?&nbsp; I've seen mention of using an ft-897 directly without it.&nbsp; How is this done?&nbsp; why hf only for the 897 when the 897 covers hf, 6m, 2m, and 440?
<br><br>5.&nbsp; what about interfacing other radios used for repeaters such as micor, maxtrack, etc.<br><br>Thanks,<br><br>Eric - kg6kqt<br>
