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

These are all interesting comments. Especially on the tradeoffs of trying to preserve the simple battery operated radio concept or trying to use the uBITX as a component in a larger system. Yes, real

Well this is not entirely true. You will get about the same performance out of the RD16HHF1 as that of the IRF510 by just replacement. Where the RD16HHF1 comes alive is when you also do other mods.

I added variable BW to my uBITX by placing BB112 VVCs across C218, C219 and C220. ?I use the RX voltage varied by a 10K panel mounted pot on receive and the TX voltage on transmit to make the BB112s

Note: I used the wrong resistor (15K) and that reduced the audio way too much. I am now using a 10 Ohm resister and now its great!
