Ici Londres ! les Francais parlent aux Francais. Another advantage using the nextion display is the spectrum analyser and the morse code reader (using the second Arduino for the standalone analyser)

Please let us know how this board works out. My biggest concern would be that it probably would need to be constantly queried. For example; If you wanted to put the tuning knob on it, then it would

On the hardware side, the interrupt pin INT, is an open drain asserted low signal (maybe better described as INT_B). This node can be wired OR'd. ( 'daisy-chained' as John described) The software

Hi Don, Thank you for your answer, directly from the maker ;-) OK well I understand what you're saying and the differences beetween. Well noted the PopFix page I've found on ubitx.net too. I think

Hello Adrien, That is not an AGC circuit, but is just a limiter circuit. No "clack" elimination but it does limit how strong it appears in your ears. It is hearing protection. I have installed that in

A minor change in the KD8CECs' source code helps a lot if you want to use the cheap 100ppr encoder. I documented what I did here Maybe I can make a video after work, then you can see the difference

Thank you that is most helpful – there are little tid bits all over the place😊 73 Murray ZL2IQ

Using 78s12 i gave scope for higher load for tft disply too Today i am substtuting 7805 on raduino with 78T05 that bought from aliex.....

I've found this from ND6T : http://www.nd6t.com/qrp/speaker.htm On his website, we can find lot of ther AGC schems for ubitx but I wonder what is the usage for this very simple circuit ? By reading

Interesting devices. The boards also have 2 or 3 general I/O pins (depending on the usage of the LED), and 128 (256?) Bytes of EEPROM. From a quick read of the Arduino library

Salut Olivier, Thank you for those informations (frenchies talking to each other in english, is kinda fun !) So, that's quite interesting the running time you have. With that information, I think I

Bonjour Adrien. The 3 X 18650 Battery pack I've installed in my V5 give me height hours running time at 10% transmitting time (on dummy load), I installed the same battery protection board as yours

Yes, keep tuned Jeff ! I'll receive all the parts in a month or so, but I've the time to design well everything to avoid losing time on the build. Also, all the designs are made with SpaceClaim, that

Here ya go Murray... http://ubitx.net/fix-fix-uneven-tx-output-across-bands/

Nice use of the design tools! Keep the group apprised of your progress. I'm looking to put together something that looks kind of like one of those WWII spy radios. The Ubitx is about the right size

Hi Can you give the URL of those transistor mods Vic. Keen to get a little more output myself. 73 Murray ZL2IQ

I received my v5 ubitx yesterday and looked closely at the xmtr on the bench tonight. As it arrived, I was getting 7W on 80m, 5W on 40 and 4.5W on 20,15m and 3W on 10. I did the 2N2222/BTR106

As far as I can tell, the only neg on the KD8CEC software is that "apparently" it does not read the encoder reliability fast enough to allow you to use a digital cnc 100ppr knob you can get on ebay

OK, looks like I have all the info I need, just set a time and take the courage to do it! Thanks

Hi Jeff, Here is the link to the thread. https://groups.io/g/BITX20/topic/8872690#54576 In summary it was the nano's crystal frequency. I changed the nano and it solved the issue. To see if it's
