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

Was tightening up tuning pot and rig went desd. Restarted and display only shows firmware version. Won't give frequency. Tried firmware reinstall but same. Nano looks to be communicating properly with

my guess requires a second SPI display and rhymes with schmaterfall.? of course with the quality of the display you speced I might build the thing just to watch movies on it. -- www.bitxmap.com (

I’ve messed with this board a bunch. You can always replace (at your own risk) the existing generated code for what you want. ?If you mess it up, reload the virgin Jackal code. Nothing ?lost.? ?

I had to dig up this thread because I just completed an FT8 QSO on 30m to ZL with only 4.67w out.? That's 1745.33mi/w.? I also hit 1508.1mi/w in the other direction a few days ago.? I'm not sharing

My experience is that the real bottleneck is not flash memory, but almost always the amount of SRAM. Since it is partitioned between the stack and the heap, the compile time statistics on SRAM memory

Hello Ralph, Coincidentally I did the same watt meter measurement last night and found a bandwidth very similar to yours: with my current BFO setting, I had a passband from 2100Hz to just under 500Hz

I'll take one too - KC9WIB, thanks, let me know who/how to pay Marc

Tom, The cat protocol was unstable until Ian fixed an overflow problem. Try with the latest sources on the github.com. - f

Hmmm...perhaps you guessed the primary reason for selecting a relatively expensive processor. Jack, W8TEE

Kees Thank you for Information. This variety is so good. I am happy to be able to use various boards and firmware for uBITX. Firmware and boards often appear in this community are missing. Nik

Ooops!? I totally overlooked the previous: Sending bugs: Send me the bug reports directly to my email?farhanbox@.... In the subject line use the word "#ubitx40". Sorry for the spam.... Tom AB7WT

The Arduino Mega 2560 has 4K of EEPROM. The Mega 2560 Pro Mini is the smallest footprint I've seen for it. Jack, W8TEE

I would like one of each board please. Happy to pay once info is posted available. W9PDS

That could make sense as a very fun toy.? A hackable 0-30 mhz receiver. I'm not convinced it's a good fit as an add-on to the uBitx. Jerry
