Jerry. I programmed something similar to what you said. I just added another setting instead of a constant(SECOND_OSC_USB). The code is shown below. if (isUSB){ si5351bx_setfreq(2,

Yes, I will test it as soon as you issue it. Mo and tue I'm going to be at home....so. Hope to hear you from some SOTA summit soon. Carlos Always tks for ur job!

Thanks Terry, I am sure everything is good.? Just excited about getting the new ubitx. Dave kn4ok

Though Ian has responded, he seems to know what's going on here.

I think I was wrong in my previous post, shifting the value of SECOND_OSC_USB won't help. The audio frequencies through the?crystal filter should be strictly a matter of where the BFO is relative

I agree with Hans and I think when the common sense fail a reminder as this a very good option for the health of the blog and the group

Clark Martin KK6ISP As a general rule, one of the terminals on an electret mic is attached to the metal case while the other is insulated from the case. The terminal attached to the case is ground.

Carlos. Wow great! It is very nice graph. My plan is to climb mountains with only uBITX. And it sends WSPR by each band and communicates with built-in memory keyer. I will Search your callsign in

Philip. You are right. I used the trick to reduce the program size, which did not work as I thought. Using a function called SetTxFiler will solve this problem easily. After the weekend, I will update

Afterthought: perhaps feed the electret from the base of a PNP? Dex

Dex You are right on. Since the electret microphone uses a microphone voltage resistor inside the uBITX or BITX-40 (or any older BITX with electret microphone) it is possible to sense voltage drop

Gerald Thanks for feedback. Errors that apply IF-Shift on TX will be corrected soon and will be included in the next version. If you test a bit more about IF Shift, we can improve it. Ian

I am not clear on the mic wiring. - Is it polarized (which terminal is which on mic)? - Is there a capacitor that is to be included in wiring?

Fanciful, perhaps, but would it be possible to detect the current drain of the electret as a PTT? Enough resistance in the feed resistor of the rig should take the electret voltage down to mid-supply

Jerry The IF Shift function should only be applied during RX, but it sounds like it is being applied during TX in error in KD8CEC's sketch.? Probably a bug. However, the op shouldn't be using the

While I'm waiting for my blown U1 replacement parts, I'm finishing up on my ubitx case.? I'm not sure the best way to mount the LCD display to the case.? I've read a number of posts but did not find

Jack I don’t know if “degenerated “ is the right word for it. To a basic new programmer of Arduino your discussion elevated beyond my level of understanding. Maybe one day I’ll understand what

Dave, KN4OK, I ordered/paid on January 12. I received notification from PayPal yesterday, March 09, that my ubitX is shipping. Since I used India Postal Service I may have another month before

If Push comes to Stack, who wins Big Injun or Little Injun?

We agree that? " Endianness is a problem when a binary file created on a computer is read on another computer with different endianness." Where we seem to disagree is that I am convinced this code
