Re: JackAl System Preview
If we went to a screen that small, I think we'd drop the touch screen feature and do complete menu system. The costs aren't cheap compared to those display sizes (e.g., > $10 versus $34), but 5" at

Re: Started my uBitx build
As for the power meter I agree it is important to have one. My first one was the kit RFprobe by Hendricks. You can probably make one 'plagiarizing' its schematic. Inexpensive, simple and it works

Hi everyone! I'm not sure I totally understand what are the spurs and harmonics, I have a faint idea, anyway. What I read on the net is that are no known issues about spurs and harmonics in the 40m

Re: UBITX Q90 mod with BFR106
Glenn, What is the actual rf power being delivered by the 2 ea 2n2222a transistors in the predriver section? Are you able to measure that? I wonder if 2 ea 2n5770s would be a better transistor in that

Re: uBITX schema relay K1

Looking at another QRR radio, they use separate relays for RX/TX signal and PWR(TX/RX). Then during TX, they mute the RX section with a transistor to GND on the input side of the RX chain(relay at

Re: UBITX Q90 mod with BFR106
Try bypassing the 11R resistors with 2000pf to 3000pf. Should make the equivalent to 2 ohms or so. Good work, by the way. Marco - KG5PRT
