I haven't done any adjustments or calibration yet. ?Been too excited getting it going. I need to Google and get the info to do them. Thinking an external audio level meter is needed. (my o'scope is

Allen K5ABL said: about the same cost as ST. They SHOULD cost the same -- the dies are identical, for equal-specification processors. 73 Jim N6OTQ

Probably obvious, but don't forget a button battery for the RTC and add code to set it when you're tethered to the PC, using its system clock to get the current date and time. There's plenty of code

I think most will tell you to snip the legs of the Nano, remove it, and carefully unsolder each pin from the board, exercising care not to overheat the board and lift the pads. Jack, W8TEE

Need device on the best way to unsolder the nano board. All help gratefully received. -- 72 and God bless KD4EPG

Ordered nano and clock board. Gonna start with nano then the 5351 ic. Anything else I should consider? Thx

Apologies if this has been answered, but roughly how many ?Bs has hfsignals shipped so far? Is there any breakdown by country available?

Hello Joe W3JDR, I have made a comparison of the STM32 *Blue Pill* , and the *Maple Mini clone* in my wiki. See: http://www.rudiswiki.de/wiki9/STM32F103Board (

Please let me have a board from each. I will pay by paypal when asked to. Paul 9H4N

Ashar, I did your modification which included shorting R83. I was careful to bag and tag all the removed components so I could remove the modification if needed. I found the power out on 10 meters

Hi Guys! I'm still trying to make the Pill work in the least intrusive way. It seems to me that the 5V from the Pill's USB connector only powers the 3.3V on-board? regulator, and everything else on

Thanks Farhan Yesterday I sat down with calipers and made all the dimension measurements, so I'm well on the way. Joe

Rudolph Theres about a dozen Nano type boards that Ive looked at on my desk. I have a couple Maple Mini clones and evaluated it. I forget why I moved on,? but will have another look. For now, I'm

Works great now, Ashhar!? I had 2 FT8 QSos and tested CAT on multiple bands.? I'll do more testing over the next few days but looks good so far.? Much thanks! Tom AB7WT

The connector is simply a 0.1 inch spaced pin out. The rest are not really important. The gerbers are enclosed. - f

Hello Joe W3JDR, A STM32 Maple Mini clone from China does have a Schottky diode between USB+5V and the 3V3 voltage regulator. Beside of the voltage regulator, see the picture. 73, Rudolf DL5FA

Joe, Be it arduino or many other miniature processor boards I find there is very little attention paid to the power management on these little boards. No overvoltage protection, no reverse voltage

Tom and others, I discovered another subtle bug in the catReadEEprom function that was causing latch up in the second transmit sequence of wsjtx. I have fixed it. I had a full QSO just now on the FT8.

Ubitx on 1.061. That's what i figured. Best plan of attack?

In tightenting up the encoder, you probably shorted some digital line to the ground. Was this on the bitx40 firmware or the ubitx? - f
