Because I receive so many tips from readers here on QRPer, I wanted way to share them in a concise newsletter format. To that end, welcome to QRPer Notes, a collection of links to interesting stories and tips making waves in the world of radio!
Check out this short article by John (AE5X) where he uses a CW Flea transmitter and Belka-DX receiver for a QRPp POTA activation. I love what John’s done here and I think I may have to give the CW Flea a go too someday.
My X6100 arrived this week and I did notice some noise on the receive audio when wearing headphones. It shows up as a 1000 Hz tone with a few harmonics and it’s loud enough to make the audio a bit fatiguing to listen to. The good news is that the noise disappeared when I added a mini line isolator between the rig and headphones. It also removes the hiss!
I like how the isolator is such a simple solution and imagine it could help other radios with similar issues. Often these noises and harmonics come from display noise. Also, your video certainly shows the improvement using an external speaker on the X6100! Thank you for sharing!
