Replies to Equalizer Info commands

Doug - K3TZR

When I send an "eq rx info" command to the radio I receive the expected response:

SCCB288B6|eq rx mode=1 63Hz=10 125Hz=10 250Hz=10 500Hz=10 1000Hz=10 2000Hz=10 4000Hz=10 8000Hz=10

but I also receive the following:

SCCB288B6|eq rxsc mode=1 63Hz=0 125Hz=0 250Hz=0 500Hz=0 1000Hz=0 2000Hz=0 4000Hz=0 8000Hz=0

What is the significance of the "rxsc" reply? Similarly, two replies are received for the "eq tx info" command, one with "tx" and one with "txsc".

When we first created the EQ it was implemented in our audio codec chip and the API commands and responses had a range of 0 to 20 for the EQ levels. In v1.4 we moved the location of the EQ into our DSP co-processor and it made more sense to use the actual values of the EQ which have a range from -10 to 10.

We did not want to break the API for developers that had already written EQ controls so we left the old API command which is "eq rx" and added a new command/status which is the "eq rxsc". Both commands and statuses are valid with the "eq rx" command using the old 0 to 20 range and the new "eq rxsc" command using the -10 to 10 range. 

The same applies to the TX EQ.

Thanks Ed,

I suspected something like that.

I'm primarily looking forward from 1.4 so when I see the "sc" form coming from the Radio I'll use the "sc" form when sending commands.

To afford some measure of backward compatibility, when I only see the non-"sc" form coming from the Radio, I'll use the non-"sc" form in commands I send to the Radio.

Sounds like a good plan. That's very close to what we do in SmartSDR.
