Help with Bitx-40

[email protected]
 

Hi all


I originally purchased a BItx40 board last year (pre-Raduino) and assembled the kit.

Recently I ordered the upgrade kit which I have now assembled and connected.

When I turn on the radio everything works beautifully and it is spot on frequency.

When I assembled the Raduino add-on I did not remove any components from the main board. I read somewhere that there were a couple of components to remove but the online instructions don't mention this.

Do I need to unsolder any components from the main board?

Also the upgrade kit included a 50 turn toroid. What is this for?

Thanks Peter VK3PB

You need to remove L4, you got a spare one with the Raduino for people who want to revert to analog!
I recommend removing C91 and C92.

Remove L4 to disable the analog VFO if you wish to use the Raduino. ?Then just plug stuff together as instructed on the WireUp webpage.

They currently ship the Bitx40 without L4 installed, and include L4 in the bag of parts for those that wish to use the analog vfo instead of the Raduino. ?Sounds like you now have two L4's.

Correct. Thanks for your help.

By the way I really like this kit. Is there a 20m version available now or in the future? Can it be easily modded to 20m?

Cheers Peter

This group is called Bitx20 for a reason, it was originally a 20 meter rig. ?To change the Bitx40 to 20 meters would require adusting the filters at L1,L2,L3 and at L6,L7, also hacking the Raduino sketch to change the VFO frequency. ?

Farhan's working on an all-band rig, it may become available through hfsigs in the coming months: ?? Incorporates some lessons learned in producing the Bitx20.

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 7.066.
?
2.) Am I supposed to hear clicking when changing freq? Also if I tune out of this freq, it just Drops down to 6.99Mhz and then I need to switch the power off and on, to get an accurate view where the freq is?
?
Thanks for assistance,
?

Evan,

When you reach either end of the tuning pot you go into “shuttle mode” and will tune in larger increments. To stop it, simply reverse the direction of the pot.

In your example had you turned the pot clockwise, you can tune up the band from the 6.99 MHz and you will get to your desired 7.088. With the shuttle tune you can cover the entire band. The limits are set in the sketch. Once you master the shuttle tune you can go anywhere within the limits.

Personally I did not care for it and have programmed mine with a push button that selects step size of 1, 10, 100, 1000, or 10000 ?HZ .
