You will become a guru in not time! I presume that you are reading 0.9 amps not milliamps. 900mA is too much by itself without shouting into the mic. Possible final blown, assuming you are getting

Thanks. I have a few to try. Some from a closing Radio Shack, but no idea what the specs are. And (somewhere... if I can find them) some from The Electronic Goldmine that are supposed to have a less

I received my Bitx40 v3 kit a couple of months ago and I've never been able to get it on the air.? I've done a lot of troubleshooting, tried updating the sketch in the Arduino twice, watched several

Hi Dimitar: I saw your comment:? (many features - many clicks ..., simple code - no clicks). and would like to you to explain how that works to me in greater detail. I know that many of us have

Hi I had also very loud buzz and tuning clicks at start. Replace your 56 ohm resistor with inductor. First inductor i tried was too small (from old computer mobo), so nothing happened. The second one

Attach one wire to the ground then and then attach the two grounds to that wire so its less of a hassle connecting both at the jack Sent: June 8, 2017 4:31 AM To: [email protected] Subject: Re:

Jerry, I forgot to mention. The LDRs seen to have a peak response (to light) at around 550nm which is red LED light wavelenght, so a plain old red LED is good.

Jerry, The LDRs that you are looking for are the ones with the lowest ON (ie; lit-up bright resistance) resistance. The Bitx volume control pot is a 10k unit so if you are going to shunt the audio

it is same ground. I have troble with the jack connector... thanks

Do a test on ptt ground and mic ground..see if its same ground is my guess. Sent: June 7, 2017 10:37 AM To: [email protected] Subject: Re: [BITX20] Baofeng microphone mod for BITX So if you have 4

Hi all, Before, I have the same problem with other transceivers, with various DDS, and with LED/OLED displays.The tuning clicks, are the software problem, connected to refreshing frequency for

But this is a dinamic microfono right? I guess it will get too much power as the board is designed to put volts on a electret mic... nice mic for the price anyway

Everyone else is getting called out and so should we. We make up the heartland of this country. So let's hear from ya. de KG5KYJ, John, Oklahoma city, Central time zone. 18' NVIS Dipole. 24 Volt

Thanks for the reply Phil. ?So you tried both the mike as is and with the bitx supplied mic element? And you saw no difference between the two? ? Was the wiring of the jack to the bitx40 straight

Datasheet says a BS170 is good for 350mw dissipation max. We normally set RV1 for bias into the IRF510 for a quiescent drain current of 100ma, which means the IRF510 is dissipating 12v*0.1a = 1.2

Good advice from everyone! When I was learning, while driving I used to read boards in my mind in morse "did dah dah" sounds! As Dan said practice till you hear all the birds and squirrels in morse!

Thank you Farhan and Jerry. Clearly I am out of my element here. My thought would be to turn down r136 so that the final doesn't get driven hard at all, and put in a smaller final like the BS170 that

My problems are due to bad connections. Baofeng uses very poor quality wires and i can see copper trhough plastic!! I have to rewire it. It is going to work i guess as i have checked that ground is
