DR-1X and AllStarLink
Jump to navigation
Jump to search
Connecting a Yaesu DR-1X to AllStarLink is no as simple as with other radios or repeaters. The easiest way to do it is using a DMK Engineering URIxB card.
The DR-1X needs an external tone generator connected when used in BASE station mode while using the accessory port.
Audio and signaling Cable
First thing you have to do is a cable to connect DR-1X and the URIxB as follows.
| DR-1X to URIxB | |||
|---|---|---|---|
| DR-1X | URIxB | ||
| Pin | Use | Pin | Use |
| 1 - 5 | Mode (Connect to pin 5) | ||
| 2 | PTT | 1 | |
| 3 | CTCSS_DET | 7 | |
| 4 | COS_DET | 8 | |
| 5 | Gnd (Connect to pin 5) | N/C | |
| 6 | Tone In | 23 | Right Audio Out |
| 7 | Audio In | 22 | Left Audio Out |
| 9 | Audio Out | 21 | Mic In |
| 10 | Gnd | 13 | Gnd |
Connect your repeater, custom cable, URIxB, USB cable and Raspberry Pi or AllStarLink computer to be used.
Repeater Configuration
Configure your repeater with the frequency you are going to use, Rx tone and do not set/enable a Tx tone (even if you setup one, it will not work on BASE mode), set deviation to Wide and disable Remote.
AllStarLink Configuration
It is assumed that you are familiar with AllStarLink ssh logging and menu. So I will not explain that here.
sudo asl-menu
Select Node Setting, next AllStar Node Setup Menu Add Node or Update Node xxxxxx and set your Node Number, Node Password, Node Callsign, for Radio interface select USB Radio (DSP driver), and Duplex Type 2.
If asked to restar Asterisk go ahead.
Exit the Interface Tune CLI, we are not using it at this time.
Apply changes, and next go to the Expert Configuration Menu and Edit usbradio.conf file adding the following parameters to your node stanza (here I use node 123456). I do not like templates from ASL3 as with multiple nodes, if you do not track your node differences, you can mess with other nodes, so I make a full stanza for each node.

Here, replace 100.0 with your repeater Tx tone.
txctcssdefault = 100.0 ; default TX CTCSS frequency, any frequency permitted

voxhangtime = 2000 ; If carrierfrom=vox, mS to wait detecting RX audio before setting rxcarrierdetect=0

; nodes, and leave commented out for repeaters or other full duplex nodes.
txoffdelay = 0 ; Ignore the reciever for a specified number of 20 millisecond

; scaling/clipping code will be deleted once existing installs have been able to verify their audio levels
Save your file.
Restart Asterisk.
Thats all, have fun.
Notes
Pre-Emphasys does not work as expected, still looking for a workarround for this issue.
