You could spend more than $59 on just a potentiometer. ?Compared to that, I suppose everything on the Bitx40 is low quality. ?That's why I got one. ?Haven't seen any complaints here about the pot

Is "unnecessary wear on the potentiometer" really a concern if that what's it's designed for?? Or does the kit come with low-quality components? At any rate, my bitx40 order is on its way, and I'm

Thanks for the support I have the very same question. -- Thanks de Hugh 2E0EHA

Hi Sorry for the delay in updating results. So couldn't find the 24v Ps I thought I had so I'm using 19v 4amp supply. I don't have a way of testing watts but I'm assuming with this voltage I'd be

The schematic on hfsigs.com ?for the Raduino shows that the Si5351 has 3.3v pullups on the two I2C lines into pins A4 (SDA, and Nano pin 8) and A5 (SCL, and Nano pin 9). ?You won't find those pins

Thanks for reminding Dragan! I have updated the instructions at https://github.com/amunters/bitx40/blob/master/operating%20instructions (

Not a bad idea, it could well help. ?Also shields around various parts of the main Bitx PC board, ?I don't think anybody here has yet tried it and reported the results. ?Most of us have adequate

This business of not connecting the ground braid on one end of a piece of coax came up in regard to tuning clicks from the Raduino. ?Some here felt that since multiple grounds from Bitx40 to Raduino

This looked like a good entry point for this question in reference to how raduimo configures the ArduinoMicro Where do I find how the port pins are used and configured?? Of particular interest are

I recently joined the group and I just ordered a BITX40/Raduino so I am trying to come up to speed. ?I am wondering if it is necessary/desirable to? put the Raduino VFO into it's own shielded box

Here is my build of your idea. The MMBT3906 is on the K1 power lead. The Base 12K goes to PTT and Collector 11K goes to ground and will be connected to the 2N7002 SMD I propose to use. The resistor

Since the introduction of RIT in v1.09, there's no need anymore to set the base frequency. You only need to set the tuning range. When the pot is max or min position, fast tuning will occur and the

Like Jerry said, hfsigs.com sells the Si5351a board + arduino + display for $25. If you're using it for experimentation with the BitX40 then it's probably the best bet.? On the other hand, it's

Great bit of info, will keep this one as a hard copy. Solved my issues. Thanks Phil - G7BZD

Right!!! New day and a fresh view of whats going on, found the culprit, had v2.02 lurking, thought I had deleted it, but no. Have followed the guide posted on the forum, both Raduino's are now

You should be able to go to the Ubuntu repository and it will do the installation. Use synaptic or apt-get.

i have two computers both windows 7 and ubuntu linux ver 12 i have successfully installed the ide on windows but i cannot se how to do it on linux i would prefer to use linux cos my windows computer

Hi Recently bought the BitX40, it says BitX40v3 on board. I have assembled it but have some issues. 1.) It seems the freq range is 7.100 - 7.150 is that correct, and if so, how do I get it to

i have ordered a bitx40 but not yet here. i have also ordered a 10 turn pot. in the settings menu it appears that you can set up the range to 200 but how do you set up the base freq = 7.00
