I have a question about using multiple PL tone.
I have a guy that is using two usb interfaces per Pi to control his radio sorta like TalkGroups or an Zedtron
controller would work like as a Community repeater.
Have any idea what I'm talking about? And yes he is using ASL on his system.

Marty,
ASL/app_rpt is perfectly capable of using multiple PL/CTCSS tones.
But I do not see a question to answer in your statements.
Do you have a question on a specific use case ?

Marty,
Multiple CTCSS tone encoding/decoding is available in the usbradio channel driver. To properly use this channel driver, you must deliver raw discriminator audio into the radio adapter. You must also drive the TX modulator with the encode tone. A complete explanation of this is beyond the scope of this email.
It is NOT currently recommended to use the CM119B based radio adapters with usbradio because of several issues. Use an older URI, URIx or other radio adapters that still use the CM119A.
The minimum number of changes to the CTCSS stanza in the usbradio.conf file looks like this:
carrierfrom=dsp
ctcssfrom=dsp
rxdemod=flat
txctcssdefault=88.5 ; Tx CTCSS Default Encode
; Encodes this tone if no other tone in use.
rxctcssfreqs=88.5, 103.5, 123.0, 186.2 ; rx ctcss frequency. this must be in the tone table.
txctcssfreqs=88.5, 103.5, 123.0, 186.2 ; tx ctcss frequency. any frequency is permitted.
Basically, if you come in on 88.5, the repeater will encode 88.5. If you come in on another frequency, you'll encode that frequency, if everything is defined correctly. There are timing parameters that can be 'buggy', but it does work to some degree. You can use any of the CTCSS tones defined in the table.

Kevin,
Hello, I believe I’m the guy asking. I set it up on the bench and it works but I am looking for the rest of the information.
Is there a full white paper on all the commands available in usbradio?
There are many references to a “Tone Table”. I’ve looked and google searched extensively for it and cannot find anything. I’m guessing it must be in the white paper.
You mention buggy however it seems to work well.
Last question, is there a status line available that would show ctcss detect, COR detect, tx keying etc?
Tnx, Mark WB2ERS wb2ers@metcom.com
Mark,
There are no other instructions that I’m aware of. If I remember correctly, the “tone table” is the list of 37 EIA/TIA standard CTCSS tone frequencies. The decode frequencies must match the tone frequencies in the table exactly, but any encode frequency is possible, within reason. Not aware of a status line.

Kevin,
Thanks. Stay well
