Re: PA breaking into oscillation? (uBitx)
I could have a balance?issue with the mixer diodes, I suppose. I'm using discrete BAT85 . . . not necessarily matched but from the same lot (Digi-Key). The BAT85 is electrically identical to the

Re: can I bypass the CP2102 chip on the NANO with an FTDI based serial adapter? #arduino #cp2102 #ftdi #nano
You should be able to connect your FTDI cable directly to the D0 and D1 pins on the Nano. The onboard chip drives the serial data through 1K resistors and allows the D0 and D1 pins to override the

I don't see a way to re-edit a post, so here it is again, I hope, in an easier to read font. It looks like the issue is with writing in another editor and pasting that into the on-line editor here.

If there is a way to edit posted messages, I'll be glad to do that. (and fix a misspelling I see, also). I only see one size font that is not a "header" size though.

Re: uBITXII
I fully agree, address the microphone audio, the frame power out issues and generally do a complete workaround on those things that have been addressed. As to the software, keep it simple and for

When you see 26 and 19 Watts, what exactly are you looking at? What mods, and at what voltage to the drains? Jerry

Are the uBITX receivers ripe for improvement? -- And some other miscellaneous thoughts.
I see a lot of good conversations here about improving the uBITX transmitter output. However, I see very little about how good the receiver is. My question is, have many people done comparisons of the

Re: boosting the power on 28 MHz #ubitx
Yes it does increase the output across the entire spectrum, but mostly above 18 MHz, and it is greatest at 28 MHz . It cancels some inductance at higher frequencies that is problematic. I see a

New software and hardware improvements will continue to come as the uBITX is purchased by more and more users. This is natural. Rather than incrementally improving pieces and parts and wind up with a

Re: Antenna Impedance Confirmation
Vince, Too bad that those little 3 digit $1 LED displays on ebay are noisy. I don't see many bypass capacitors on that thing. Turns out the analog input pin on that SOIC module they use (no ID

Re: PA breaking into oscillation? (uBitx)
It is probably a layout or decoupling issue. You have a feedback path from the output to the input. It might be a power supply decoupling issue. Try driving the output stage from a seperate power

Re: Should we adopt the KD8CEC firmware?
One of the things the uBITX is best at, is a learning platform for new hams, and more experienced ones that may not have much experience with microprocessor based radios. Leave the stock firmware as
