Anyone have a working node using an SCOM 7330 in line? I currently am trying to get these two to work. It's about 80% right now. Audio from the node box is making it to the repeater and keying the transmitter, no problem there. The problem I'm having is the audio from the repeater not getting into the node box. I see the audio on a scope at pin 9 (mic_in) on the URI. I also have a transition from high to low on pins 7 and 8 (COR Det and CTCSS Det) when the 7330 tells it to transmit. On the 7330, I'm using port 1 for the repeater. Port 3 is connect to the URI. Paths on 7330 as follows: RX-1 to TX-1 RX-1 to TX-3 RX-3 to TX-1 In rpt.conf I have duplex=0 and linktolink=on In USB radio I have carrierfrom=usb and ctcssfrom=usb Looking for thoughts / suggestions.

We are working on this now. I just built a cable and needed to add a pullup resistor at the URI COR input between pins 8 and 14. If you're using the CTCSS input, you need one there, too. I added the pullup in the DB-25 shell.

Since you are connecting the URI to the controller there is no need to use the ctcss input to the URI. I'm assuming the 7330 is validating the pl on the repeater port. You only need to make the following connections: cont PTT - URI COR cont COR - URI PTT cont TXA - URI RXA cont RXA - URI TXA You may need a pullup resistor on the controller cor input though. The URI does not require pullup resistors (they are internally built in) on the cor and ctcss inputs. What they require is a transition to ground in either active hi or active low. So they can be connected to open collector outputs. No voltage needs to be sourced to the URI. The inputs are diode isolated to block the volatage anyway. Since the PTT from the controller is act lo, then the "corfrom" needs to be set to usbinvert for active low. and the ctcss input on the URI can be ignored.
In USB radio I have carrierfrom=usb and ctcssfrom=usb
Set carrierfrom to usbinvert and ctcssfrom=no and comment out the pl frequencies in the default tone, RX tone and TX tone lines. Restart Asterisk then you should get audio to the node from the controller. Hope this helps. Jon VA3RQ On 2/3/2013 10:05 AM, Dave Maciorowski wrote:

Mornin' Jon,
You may need a pullup resistor on the controller cor input though.
The 7330 has jumpers on each COR and CTCSS logic input of each port. See pages B-4 and B-5 of the 7330 manual. Thanks for the correction on the need for pullups on the URI. 73, Dave I On 2/3/2013 9:09 AM, REDBUTTON_CTRL wrote:

Thanks Dave for the tip. I'm heading back out to the site to work on this some more. I will give the pull-ups a try. Maybe that's why it's not streaming out. How did you resolve the setting of the receive levels running 'radio tune rxnoise' etc, with the URI connected in this manner? Thanks!

I suggest setting audio levels on the controller first, then do the URI adjustments. Set as follows: in usbradio. conf the audio setting should be : rxdemod=speaker txprelim=no This assumes the audio on the 7330 port is de-emphasized and does not require pre emphasis to and from the node. Disconnect the URI from the 7330. 1) Send a full quieting signal to the repeater with a 1k tone @ 3k deviation. Set the TX audio level on the controller URI port to 1v p-p. 2) Connect an 1K audio tone @1vp-p to the RXA pin on the controller port and gound the COR in line. Adjust input level to get 3k deviation on the repeater TX. Now you have the controller levels fixed. You new need to adjust the URI to these settings. Connect the URI and node to the controller. 3) Send a full quieting signal with the 1k k tone /3k deviation to the repeater and on the URI CLI console do a RADIO TUNE RXVOICE to measure the input level. (Dont worry about the RX noise adjustment - not required as you are not doing any DSP with this setup) 4) Do a RADIO TUNE TXVOICE 500 and measure the repeater deviation. 5) Repeat step 5 with different level until 3k deviation is reached on the repeater TX deviation. 6 Do a RADIO TUNE SAVE the set the audio levels on the node. 7) you are done.
