Expert Advice Needed
I will be starting to assemble my uBITX after the case is delivered on 6/1. ?I received the uBITX on 4/18 and have been waiting for the case to delivered from India. The board I received is marked

Re: uBitx sound
You probably need to adjust the BFO to make it sound more natural.? The BFO calibration is in the Setup menu list. Dan, W2DLC

Re: What does zero-beat sound like? #ubitx
You can¡¯t discriminate down to zero Hz unless you tap off at the right point with a DC amplifier. The AC coupling provides a high pass filter that will block the signal above some frequency. I built

uBitx sound
The sound from my uBitx has no bass. It sounds like an ancient mini-transistor radio receiver. Is the speaker from the Inkits case so bad?? My Youkits HB-1B on the same frequency and small external

Re: What does zero-beat sound like? #ubitx
Easy enough to place the BFO at the center of the 12mhz crystal filter, then the near zero hz beat comes through strong as ever. In the equations of post? ??/g/BITX20/message/44278

Re: SDR as Waterfall display
BTW on transmit you get the transmitted signal spectrum. Quite nice! (I do reduce the gain on transmit!). FreqShow runs on a Pi¡­ needs to be moved to a Teensy. Dr. William J. Schmidt - K9HZ J68HZ

Re: Need Clarification on uBitx v. 4 Schematic
To my eye, it looks like parallel, though I'm left wondering how they'd mount. The RDs would have better 10/12m performance, the IRFs better at 80/40m. Not quite sure on biasing/static currents, but

Teensy I2c on wire2 (SDA2/SCL2) #ubitx
Has anyone ever gotten the I2C LCD display AND the Si5351 clock chip to operate on SDA2/SCL2?? Looking to get that running on a Teensy3.6 if possible.? Any help from the group would be very much

Re: Simple sound card interface #ft8
Thanks Doug, I followed your instructions and was able to make several FT8 contacts yesterday. I wonder what the 1K resistors are for across the audio outputs. Can they be eliminated? 73, Dennis W7DRW

Re: What does zero-beat sound like? #ubitx
Interesting, I will have to look at this at a level that is more than casual. I was thinking that one would be discriminating to the limit of zero Hz. I do like the idea of the Nano or Uno or...
