FLAT vs Preemphasized audio

We plan on interfacing with a Palomar repeater controller which uses FLAT audio in and out. It is designed strictly for disc audio in and output directly to a radio’s modulator.

Would the settings…

RXDEMOD = FLAT

TXPRELIM = YES

… be correct to make sure the Palomar gets already pre-emphasized audio in and audio coming from the Palomar to the URI is de-emphasized in the URI before going out to the rest of the network? Many of the other nodes on the network are using MIC inputs and “Speaker” audio out.

Would these commands go in the usbradio.conf file?

If it is a DMK URI, would the same commands go in the simpleusb.conf file?

Seems I remember setting something like this in the initial DMK setup…have only done one DMK.

Not sure if final unit will be a DMK or some other URI.

…I know…a lot of questions!

Thanks…

The settings you have thought to be for usbradio.conf appear to be
correct.

Not sure about the simpleusb for DMK URI. You can use the DMK URI with
usbradio.conf. I like the usbradio.conf over simpleusb, seems to me a
lot of folks are having issues with simpleusb.

Remember to use radio-tune-menu with a service monitor to ensure your
TX/RX audio levels are set appropriately!

Have not heard about problems with "simpleusb.conf" ??? Any comments on that?? New to the reflector.

Nothing but an HP 8920 and scope for levels! Only way to fly!
