Running 3 nodes on the DIAL release is likely not going to work. You may want to try Doug and David's release which uses a different channel driver. I've never heard anyone having luck running more then 2 nodes on the Raspberry Pi release in full DSP, but I have heard of success with the other.<br>

Hi Kevin and all:<br>
<br>
Wow - lots of discussion going on today, so I will jump in help divert the discussion!<br>
<br>
So... for one of my 220 repeaters, I did confirm that the USB fob I was using was one of my earlier versions, which only had one audio output - hence the reason why I was not able to get the 'split' PL working - doh! - my bad ;).<br>
<br>
My 2nd 220 repeater (yeh, I have 2 x 220 machines that I am lucky enough to be working on at the same time!) - this is a pair of Bridgecom BCM220 mobiles (identical to the radios used in the Bridgecom 220 repeater package) - this repeater is connected to a fob where I did bring out both audio channels. So hence, I am able to split the PL and inject that into the 'data' input of the BCM220 radio. This works well - so all good there!<br>
<br>
What I am observing is that I have some high frequency noise on the audio out of the Bridgecom TX radio; it's subtle, but it is there. One thought that I had is whether this was coming off discriminator of the RX radio. I turned the RX radio off and the noise is still there. Now coincidentally, I saw a message scroll by the display on the TX radio "PLL UNLOCKED" - ta da... is this synthesizer whine that I am hearing??? - I am going to test with a local mic tonight and see if the noise is still there (independent of the USB fob / app_rpt, etc...).<br>
<br>
Running 3 full-duplex nodes on the Pi - I've been doing that for sometime; the difference now is the radio's - the RPi 2 and fobs are the same. I didn't have this issue before.<br>
<br>
More to follow... but for now, I wanted to provide an update and get us back to a technical discussion! ;).<br>
<br>
Cheers,<br>
<br>
Ramesh.<div class="HOEnZb"><div class="h5"><br>
