I’m curious, the device I’m using, USB Duplex Repeater (USB Duplex Repeater), requires that a switch to be set in one direction to set the receive parameters & then set to the other direction to set the transmit side, how would I go about programing this using ASL3? I tried last night with limited success. The radio would transmit during the boot up process but it would not respond when I tried to key it up. Thank you for your help!
I would say consult the manufacturer.
Did they provide instruction ?
ASL is set to take input and give output with 2 methods generally speaking to COS and PTT
A parallel port and a URI based on cmedia sound fobs. where those lines can be extracted.
Not withstanding the device, it has to fit within that or provide its own means else-wise.
Within that, it should be no different as the cmedia based device.
But these are configured in simpleusb.conf
Also see the wiki
They do provide instruction. However, using sa818-menu in ASL3 doesn’t have an option to program the receive side of this node & then program the transmit side. At least I haven’t found the proper way to program it yet.
To program your SA818 using the command line you can execute the sa818 command. For command usage information, use sa818 --help.
While I can’t really say much about this, it seems the device should have it’s own utility to set freq’s…
My understanding is that you setup the HSR to program either the RX or TX side. Then you would use sa818-menu to configure the selected RF module. Next you would flip the switch on the HSR to program the other module and again use sa818-menu to store your configuration.
Note: the sa818-menu command does not give you the option to “apply” the settings if you haven’t made any changes. To force updating the module (or to program a second module with the same settings) you have 2 options. First would be to change one of the settings to a different value, then switch the setting back, and lastly apply the configuration. The second option would be to exec `sudo sa818-menu --apply". This command will re-apply the last stored configuration to the RF module.
Note: the sa818-menu and sa818 commands cannot query the settings stored to the RF module. They can only set a new configuration. For sa818-menu, the last stored settings are saved in a file and read back in when the command starts.
And note that the HSR cable is “directional” in that one side up is radio and the other side up is program.
It’s two independent SA818 radios on a single serial controller. There is a switch between the two SMA connectors. Program on e with sa818-menu, flip the switch, then program the other.
I typically set mine up as if it is two simplex radios, I.E. RX radio is set to both RX and TX 440.025, TX radio is set to RX/TX 445.025. This is a standard 5 mHz offset, which we use here on UHF, and a repeater pair that isn’t used or coordinated by anyone in my area. I listened to the frequency pair on a high gain antenna for a long time before putting my node there.
To be fully clear the SMA connectors for the antennas is not controlled by the switch. Just the USB serial port link for programming the radio modules. @KE4DYI was just pointing out the physical location.
Yep. There is nothing special about the cable itself, other than the sticker. The USB C port is wired with 4 pins going to the sound fob, and the other 4 going to the serial controller, I guess to avoid having two physical ports. Thus, the direction matters, but the included cable itself isn’t electrically special.
Thanks everyone. Really helps to read & re-read the instructions AND try not to over think that for some reason programming would be different on ASL3.
