m, Check your wiring, probably in the audio connections. Check the stock volume control for proper value etc. r

I'm at last got my uBitx wired up: slightly older (2017 date) board, in out-of-the-box condition with no mods or software updates. Based solely on reading, I believe I might have the TDA2822 problem,

Yes that is true, if I didn't originally learn C on non-optimizing compilers for simple machines and check the "real" code, assembly, to see if C was dong what was expected, I think my understanding

very nice Darren, thank you very much. Kevin REa K6REA

Hi Tom: I did look at the assembler output for a similar thing over a year ago and the compiler did make the optimization anyway. I'd be surprised if the GCC didn't make the change you're talking

I've cleaned up a few things on various screens.? The same download links above should now download the updated versions. Darren

For 15.5 nSeconds read 16.5 nSeconds in the input capacitance calc of last post. TF.? Obvious kludge? Simple untuned emitter follower stages in class A will also give the effect of a coupling

C'mon Jerry I think you are being a bit harsh.? I stated explicitly that the NN1G design was class C but it introduced? class of chips that people have been dismissive of.??

There are other displays available: https://www.buydisplay.com/default/5-inch-tft-lcd-module-800x480-display-controller-i2c-serial-spi 2.8 inch ILI9341 based touch screen display which is widely

So to elaborate on my previous really short reply. I really like the macro, it handles the hardcoding the number of elements issue well. For the definition inside the loop. I may be trusting the

Hi, A team of french operators kindly translated the installation and user instructions for the Raduino sketch for BitX40. I've included them in the Raduino repository on Github:

Hi Allison, It was not clear in my post that I was not expecting the increased voltage to fix the harmonics and replace the needed fixes to output filters and such, but only to help with the drive to

I meant stock.? I went back and fired it up.? It went from a few below 7.05 - 7.5Mhz.? Which makes sense.? That was with Raduino V1.01.? Getting ready to load a newer version.?? Thanks 73,

Needing help from all! Attached as a .PDF and LibreOffice Spreadsheet. Please provide input!! Goal is to make it into a club project, simplified as much as possible. Thanks, Bo W4GHV since '54

Yup, I skipped 17m. Also 30m and 60m. Those smaller WARC bands are supported, go for it! Jerry

Hi Terry, The new group has already formed. If you haven't already signed on it's on grups.io. Login and search for HBTE. 73, Bill KU8H

Sure, lots of ways to build an amp. The DSW-II with the LT1252 was a CW transceiver, that attachment is not a recipe for a linear amp.? If starting with what's on the uBitx and wishing to bring gain

Hi Jerry, I think you omitted 17 meters in that lineup. I am using external filters for CW on those bands and keeping it under 10 watts. 73, Bill KU8H

Simple answere is NO .? But there are advantages as per below. 1.The Pinning on RD devices is GSD with device flat on its back. ( that means inter alia the final transformer has be direct wired to

It has all been done before over 20 years back.? LT1252. It has essentially infinite input impedance. In this cct it is providing 5K input Z to the wiper of the potentiometer.? This chip can produce
