Bo, I was thinking about using my SDR Play 2 behind the bandpass filters of the uBITX and powering it with either an RPi3 or an old 2.5 GHz ATOM.? The latter would give me choices for logging and

One small point.? If your using diode for reverse polarity protection it is better to place the fuses BEFORE the diode as then the fuse blows and the diode is less likely to be fried and also down

Great job!? I work qrp also.looking forward to rebuilding my antennas. Several years ago I qualified for the 1000 mile a watt award. But I was using an Argonaut 509. Great job! Sent from Yahoo

Hey Bo,? According to all drawings and the HFSignals wireup page: * Tip is Mic * Ring is PTT I hope that helps

Should work fine. Note that the Nano has an FT232RL USB-to-serial chip that includes a 5v to 3.3v regulator.? This currently powers the si5351 through the Nano's J2 pin 14.? On the clones, it's

Can you verify that the orange PTT goes to the sleeve? It is shown to the tip on the Randino schematic I found Bo W4GHV

I was wondering something similar, to remove the USB section of the Arduino Nano to clean up any birdies caused by it.. thoughts? Nick VK4PLN

The uBITX continues to be great fun!? As per the attached logbook snapshot, I was able to work 9 bands in 1 day last week with 10 meters through 80 meters.? The contact on 10 meters was only a

I updated the Assembly page with pictures, no making fun of my soldering. ;-) I could use help with two things as I did not do a vanilla installation of these two. 1. The microphone? 2. The Keyer If

I really need to purchase EZNEC or something similar, because I need to be able to run some reasonable simulations.

I hear one other station intermittently. Lots of QRN here. ? -- John - WA2FZW

they are starting to come out of the woodwork. Hearing stations from Nova Scotia VE1ESP to Alabama.

Bear in mind,....? ?sometimes when you buy RD16HHF1 fets? from EBay, China... you don't always get what you expect,....... Sent from Samsung tablet.

Hans, would it be possible to pull the crystals in a filter using the LED or Zenor Varicap diodes?? -Justin N2TOH

I setup for the FT-817 38400 baud and do have transmit control. Am I supposed to have more (frequency control, etc) with fldigi & wsjtx or just transmit/PTT control?? I see a conflict on two

I'm on with Tom, VE3THR with pretty good signals! Anyone else on? -- John - WA2FZW

I wanted my ?BITX to power-on on our club meeting frequency, instead of having to navigate to it every time. Couldn't find any documentation on how to set the default frequency which is (was) 7.150

Thanks, Allison!

After listening to mine today on FT8 ?I'd say the RCVR I'd just fine. Or mighty fine! It's been a joy listening to CW, SSB, & FT8 ?today. I have problems on the transmit for another post. Definitely
