A simple lm386 module comes much cheaper, and can be adopted removing the discrete section. wrote:

Here are a few pics of some of the bigger changes.

Hey, Sam. This was a really quick-and-dirty type deal. I mainly wanted to make things easier to see at a sit-back in the chair distance AND have the buttons react, rather than have the sensory

Hi Ted. We actually have a lot of errors to deal with. For the read control, i just deleted it and recreated. There are a lot of sizing issues and a few missed controls. Not too bad...I got tied up on

I haven't played with it while actually attached to a radio much, yet (been doing family stuff).? Would you please PM me with your corrected HTM file and let me know how you got the "READ" back on

For what it's worth, for the price of a 7806 regulator you can buy a NJM2073D (US$5 for five units on eBay), same footprint as the 2822 and runs on up to15 volts.? Does not explode on contact with

I don't know much about the radio control programming setups though it sounds like your program was written for the V3 and V4 - the IF frequency that the rig keeps resetting to, suggests that this is

I just noticed that the pictures had been resized, i uploaded them to a hosting provider: TTL - uBitx on ( https://www.directupload.net/file/d/5387/nbg7eofi_png.htm ) TTL - uBitx off (

As you have probably figured out, the schematic for the Bitx40 is at the top of this page: ? ??http://www.hfsignals.com/index.php/2017/11/23/bitx40-circuit-description/ and the assembly

Hi John, I guess i made some progress. I have a small oscilloscope for PC usage which i just dug out to visualize and check the voltage Levels - and i got some interesting results. At first i

Need some help please.... I have wired up and enclosed a ver. 4 ubitx40 and am having trouble getting the encoder to respond correctly in order to change bands, or go into setup, or tune. Am able to

Hi Curt, if these are the values of an unmodified unit, some bands were clearly out of spec but not terrible. My ver 3 board without the Axicom relays was worse. Coilcrafts are good stuff, I have some

I am building a bitx40 and got a larger 16x2 display. Not sure how to connect the data lines.? The Raduino J2 pins: J2Pin? ? Arduino? ? Function 4? ? ? ? ? ?D8? ? ? ? ? ? RST 6? ?

I have a ver5 board that I ended up loading the 1.08 radio control software in. the problem is in the BFO it was with the original software 11.055.3 but now it keeps resetting to 11.997. If I turn it

Iz while I am a decent operator - SO2R is way over my head.? I am using the same LC design as v5.? the inductors were found in a junkbox - they are coilcraft (and not a small footprint) so I

Ok, thanks for the hint, I certainly need it. I will start with simulating a dummy load hihi
