Greetings Experts! I need more help with my GM300/URI node project. I thought I was on the home stretch after struggling through the "RSS on modern hardware" stage; but, I am still having problems (and I am still new to radio). I am trying to connect a GM300 VHF 16 channel via a URI to my Raspberry Pi2. I am also trying to connect an M120 UHF 2 channel via a (separate) URI to the same Pi2. My friend and I wired the 16 pin accessory cable to DB25 according to the directions we found on Allstar and DMK (we were not using the COR pin option). Our results were that we could connect to the node via Zoiper or iaxRpt and talk and we would hear it go out the radio (whichever one we were testing). We could trigger CW ID, time, etc. and we would hear it on our handhelds having been transmitted from the GM300's. However, when we transmitted back from the handhelds, we hear the GM300 receive it on its speaker, but we don't get any audio back into the node/soft-clients--although we do hear a courtesy tone generated. I have since gotten in the GM300 VHF and observed that the JU551 jumper was in position B, so we rewired the 16 pin accessory to match that. I followed some instructions to program the GM300 VHF Pin 8 to "CSQ Detect, Output, No, High" within the "EXT Accessory: Public Address" screen. I still have the same results. I have tried adjusting parameters within the usbradio.conf file to no good effect. I have also tried running radio-tune-menu. I am a little confused by menu option 3: "Set Rx Voice Level." I don't see the little text signal indicator fluctuating although it does occasionally flash up and then disappear. The simpleusb-tune-menu command errors out with "Error parsing device parameters." My friend and I have a growing discouragement about this project, and to make matters worse, we're entering the stage where we have changed too many things. I guess I am seeking answers to these questions: * Would someone be willing to send me a copy of their usbradio.conf file to examine if they are successfully running this configuration? * Is running two nodes on one Pi2 causing me additional issues? * Should I see the radio-tune-menu Set Rx Voice Level indicator moving fluidly when the radio is receiving? * Are "CSQ Detect, Output, No, High" within the "EXT Accessory: Public Address" screen the settings I want to program pin 8 on the radio? I notice that there are a lot of other screens besides Public Address. My thanks in advance to those offering help. 73, Doug KI7DQG ki7dqg@gmail.com
