I suppose the sunil vu3sua is also selling these boards from his Indian site

Upload a crisp photo on the internal main board. let us see.

Obvious that only Farhan can bring out the price at the due time

Are you using electret mic as the mic pin is having dc bias voltage? Generally we provide a 1nF cap across the electret. That filters rf induced on the mic cable. Reg ver 3 drawing 650mA on Rx with vo

what is version # please?

I saw but!

Once you have thought of using raduino, i suppose you could use one with nano and si5351. You could derive bfo and vfo also. On the bitx you could stop populating the crystal bfo, but use its buffer t

While homebrewing Sunil's bitx 20 or any other older version with through hole components , can better use quarter watt mfr and preferably mlc capacitors. Sarma vu3zmv

That is obvious. Leet us check at nominal volume and ant connected. Then if you remove the antenna, the audio is near silent. All thebest. Sarma vu3zmv

Congrats Kelley, you solved it.

Hi Kelley, Try to place on 1000pf (1nf) capacitor across the electret mic. Things should improve. All the best. Regards Sarma vu3zmv

The creator of that article deserves the appreciation., Thanks Steve Regards Sarma vu3zmv

https://petetest2017.files.wordpress.com/2019/01/micro-bitx-calibration-instructions.pdf I got this link from a friend om mahesh vu2iia. It works. Whether stock or lees firmware procedure is common .

I wonder whether the O P has used 4k7 resistor between key wire and 5v vcc( blue and green wires)?

Raj, perhaps you got what i was suffering. Regards Sarma

I learnt another point today. Thanks Saneep jee

Dear Pratap jee, Your power inside is really welcome . One could take out the rig to field, with some end fed or a fold-able vertical antenna and used for an hour. Other mods are curiously awaited. Be

Hi Cristian, Please upload a screen shot of your error. secondly, please check whether you have set the port and Port has recognised the CH340G usb interface. Finally define the chip as atmega328, and

Try with ide 1.8.5 Define mega328p old bootloder Regards Sarma vu3zmv

Even if one is rich, i suppose that there is no point in investing in mics that zerve high end systems for ham use. We dont really need more than 0.3 to 3Khz at the maximum Regards Sarma vu3zmv
