Re: distorted FM

I had recently installed ver 1732 along with that gaggle of plugins that is offered. My WFM sounded like crap.
I found the audio processor plugin already enabled,which caused the very poor WFM audio quality.

Re: Error When Turning On Bias-T

I can't help with your issue but I will tell you that most rtl-sdr builds don't use biast anymore. If you do a rtl_tcp -h .... you'll see that T bias is turned on with the -T arg now. Also if you did use the rtl-sdr -blog build ....you can use rtl_eeprom to latch the tbias on constant between boots....

Re: RTL-SDR HF Mod effecting normal bands?

You didn't mention which app you use, so try a different one SDR#, sdrconsole, gqrx, etc...
If your still have issue, consider what rtl-sdr your using...like keenards, vs osmocom...
Also when using direct sample, you need a "good" antenna

Re: GNU Radio isn't working with RTL-SDR

I would say you have to open the rtl_source box and add a line in the Device Arguments field like
rtl=0 or other info.

Re: Max Volume

I really don't think this has anything to do with your antennas. I think your audio setup has issues. Like some mixing. With your wx app running in manual record mode.
