The January Tech night was about getting the most out of your HF transceiver. Fred had an interesting  PowerPoint presentation where he demonstrated how to do just that. For anyone else new to HF, I wanted to comment on it here. In his presentation, he described how you should use filtering first and digital signal processing (DSP) as a last resort. That’s the exact mistake I was doing. if you use a lot  DSP with a narrow filter selected the audio sounds hollow and really difficult to listen to. If you turn off the DSP  select the narrow filter and then bring up the DSP if needed you get less noise and a pleasing audio output. Also turning down the AF gain can be your friend too!

73 and good DXing
