Thanks for responding. If I really want more power, an external amplifier would be the way to go. Since that December post, FT8 has caught my attention, and more power would be overkill.

When I press the Raduino reset and the controller button the display briefly shows "Raduino 2.0" before returning back to VFO A: ?7.150:000

The ATMega328P processor chip on our Nano processor (which in turn is mounted on the uBitx Raduino board) talks to the Si5351 oscillator chip via a two wire i2c bus: ?

I would also like to purchase one of the AGC kits. Thank you 73, Guy N7BIR

Hi, sorry but somewhere down the line I must have missed something. ?What is an i2c? ?More specifically, what is an i2c periferal? regards Norm vk5gi McLaren Vale South Australia

I desoldered all wires from the encoder. The push putton funktions works from open circuit to 0 ohm when I push it. Connecting the yellow and red wire doesn't change a thing on the display. I

Dennis W7DRW Perhaps I can provide a little information that may get you started. The .hex file is generated by the compiler. In the Arduino IDE on Linux it is stored in a temporary directory. Windows

Attached is a schematic of the variable IF circuit. ?The RX and TX voltages are about 12V, so I used a resistor network to keep the applied voltage to about 1 to 9V because that is the usable range

Tim, I am a little confused by your post titled Re: [BITX20] Should we adopt the KD8CEC firmware? You mention a feature you may want to implement. To me, whether the 'base load' is hfsignals firmware,

OK. Figured it out.? Relays are fine. The culprit: I have?a PCB trace,?with the node/net L1, C200, C80 running parallel to my RF output trace (from relay KT1, pin 5) causing feedback. Doh. I should

I finally got around to designing and printing ?BITX panels for the EF01 enclosure.? I switched out the LCD for a white on black one.? I ended up recessing it in the panel to avoid the need for a

I get 3.0 mV to the connector with good continuity to the microphone.

if it was carefully and intentionally engineered with design documentation that will open the door for experimentation then I am all for it..if it was hacked on the fly with no or poor documentation

Well, Ash. It seems to me that there are too many opinions to change things very much. It is probably best to leave things pretty much as is, and let each user determine what's the next best thing to

Think of it this way. I want to add a Tune item to the menu. The item will send a CW signal and monitor an i2c peripheral for reverse power indication while the CW key is held down. Do I duplicate the
