Question regarding Direct Sample Mode #7

Closed Brent-Davis closed 4 years ago

Brent-Davis commented 4 years ago

Just wanted to say I'm loving this app but I can't figure out how to set Direct Sampling mode when using this with an RTL_SDR v3. In most other applications like GQRX its just a matter of setting an argument. Are there any arguments that are passable for SdrGlut?

righthalfplane commented 4 years ago

I am not sure how set things up for Direct Sampling mode - I will have to look into it.

righthalfplane commented 4 years ago

That was simple enough - it will be in the next release. If you are in a hurry, you can clone the SdrGlut directory and build SdrGlut - the Direct Sampling mode is now in a pop up menu.

Thank you so much for working on this. It would be really awesome to get on HF with the RTLSDR v3 dongle. I just cloned the SdrGlut directory and tried to compile but I'm currently getting an error. Trying to poke through myself and see if I can find a solution but I'm not much of a coder. Anyway here's what I am getting:

Got it to compile! These lines were causing the issue for me:

else

f->demodAM = ampmodem_create(0.5, mode, iflag);

Once I changed those I got rid of the errors and it compiled. And direct sampling is working great. Listening to HF right now as we speak. Thank you so much for adding it!
