Just in case someone else decides to try this. reference this. http://www.repeater-builder.com/motorola/maxtrac/gm300-info.html a) on the GM300, leave JU551 set to the default (de-emphasized not FLAT) position B b) also make sure that JU701 is set to the default position A or else you won't encode PL on TX Beyond that, I used beagle tune to set the levels, and the portal to give me a basic node setup. I did play a little with the wait-times in rpt.conf. settled with these for a simplex node. [wait-times] telemwait=1200 idwait=500 unkeywait=300 calltermwait=1500 I did use cables from Marshall and he includes an rj45 with the wire to jumper so that with no mic connected it's onhook so that PL functions correctly. I was lucky enough to have 2 real live GM300 D04 radios (1-10watt versions with 439-450 coverage), I plugged in 446.000 with a pl on tx/rx and didn't have to touch much else. RX sensitivity was -122db on radio and -120 on the other. good enough for what I'm looking for - personal simplex nodes. if you get cables from Marshall make sure you follow his instructions and pin 8 on the back of the radio needs to be set to show both CARRIER *AND* PL. The Beagle.conf looks like the following [YOURNODENUMBER] carrierfrom=hwinvert ctcssfrom=no invertptt=0 duplex=0 rxondelay=0 That's it. if doing a simplex node, and using the portal to generate your starting setup, make sure you select all the right things for the node radio interface - beagle, then the other items below it, specifically the duplex= Hope this helps for the next person. Note, I tried JU551 on the beagle and in FLAT mode it just sounded tinny - probably would work great in a sideband contest, but with it in the default position, the audio across the network sounded much more *natural*, the way it should. NOTE, this may be an artifact of the Beagle, none of the normal usb setup values are support in chan_beagle.c, etc. And lastly thanks to everyone who offered their nodes to me. it was a huge help. With my main allstar server on the same network as my 2 new nodes, while I could get the big allstar server to see both separately but using separate ports, I couldn't connect one to the other. So having a node out in the networks. Solved the problem. Alan
