Thanks, Gene, and I’ve found the files - it looks great and exactly what I was looking tor. 73 Peter

I have started working on a TFT display for my uBITX.? So far I have only tried a 1.8" tft? 160 x 128, because it can be wired in to the existing connector without having to do any level conversion

Mike WA6ISP When you connect a resonant antenna most of the birdies will go away. They are a result of the receiver being very very quiet and the volume control setting being quite high. The 7.12

Mike, I just took a listen on 7.120, quiet as a mouse, in fact I haven’t noticed any birdies. Joel N6ALT

Mike, I would suggest that You first try the opriginal i.e. Raduino to see where the birdies come from and then start experimenting. Henning DK5LV -----Ursprüngliche Mitteilung----- Von: Michael
