Good morning I was advised to upgrade to the Allard's version https://github.com/amunters/bitx40 that solves many problems! I downloaded the zip and unzipped it then I installed the Arduino/Genuino

I would go with the rtl-SDR.com v3 dongle. I use it with my Yaesu FT-840. And I have about 4 others that make up my radio farm. To me it’s the best design of the dongle type SDR’s no need to get

Hello Anyone have a suggestion for a rtl sdr device for use with uBitX? Best Regards, Stein-Roar Brobakken post@... LB3RE K3RAG Skype: lb3re.rag

Hello Resti, It depends what you mean by "via bitx". If you mean without the addition of an external device, I don't know of such a solution, but it may have been done by someone. It is technically

Hello everyone, can we send gps data via bitx? thank you

Thank you. These links look good. Regards. Max K 4 O D S. I've Never Lost the Wonder. Antique Electronics Site: <http://www.angelfire.com/electronic/funwithtubes/>

Not all ground wires are black and not all black wires are ground. The mic ground is blue and the ground for keyer and encoder is yellow. The encoder A connection is black. Mike K5ESS Sent:

The grounds for the arduino are located on several pins - marked gnd The rig grounds are the black wires but i test them to be sure. I keep my grounds short and tie them to the chassis. Either

Hi, Sorry if this has been addressed, but I have a question regarding the grounds on this board. Are the grounds for the Raduino (terminal 4) and the audio grounds considered common grounds? And can

I assume a 10M leaded resistor from RF-in to ground is what you are suggesting? That will be a lot simpler for me to do than adding an RF gain control. The front panel is getting pretty crowded! tim

My braid is grounded at the entrance box to the house. I also made up shorting plugs for when I unhook the antenna so the center conductor and braid should both be at the same potential. tim

I guess that then assumes you have a very simple tuner (Cap-L leg)? No impedance transformers, inductors to ground, etc. Dr. William J. Schmidt - K9HZ J68HZ 8P6HK ZF2HZ PJ4/K9HZ VP5/K9HZ PJ2/K9HZ

I agree! But if the problem here is static buildup then a tuner won't help any more than the coax connector on the rig! tim ab0wr "K9HZ" <bill@...> wrote:

I wound a ft37-43 ferrite to get 33uh. Not as neat as an smd inductor but I ddin't have any of them! tim ab0wr "Howard Fidel" <sonic1@...> wrote:

Thanks Arv , info much appreciated. Norm vk5gi

This is used with the Sotabeams LaserBeam Dual variable kit. I didn't like the limited mounting options or the point-to-point of the filter kit so I made this board for my projects and had a few left

The AGC writeup does mention that the RF gain control is assumed, but the diagram just says "To K3 pin 14" where I assume it should say "To Wiper of RF Gain Pot" ?

Chris: The parts caps I have are smaller then the resistors on the board, I think they resistors are 0805. It is not too difficult to solder one on top of the other. Electrically, it doesn't matter
