Within the hour I will be uploading Release 1.00 of the software for the TFT mods discussed earlier. This software assumes you are using the PCB, AD9850, Mega 2560 Pro Mini, and rotary encoder as was

Can we add fine tune as a option that can turn on and off in the normal mode settings w/o the "tune" button? I also noted in my Bitx I am about 45Hz off so I either get 40 or 50Hz I can't fine tune

Excellent idea Vince! I'll include this suggestion in the "user instructions" of the raduino software. 73 Allard PE1NWL

Vince Thanks. I will try it. Arv _._

I've just released raduino_v1.18, download it from https://github.com/amunters/bitx40 ( https://github.com/amunters/bitx40 ) New in this release: * improved CW performance at higher CW speeds: -

Allard, Thanks for the pointers, I will try again. Joe

Joe, do something like this: if (USB) // if we are in UPPER side band mode si5351.set_freq((IF + Dial_freq) * 100ULL, SI5351_CLK2); else // if we are in LOWER side band mode si5351.set_freq((IF -

OK I have worked out the circuit hope you can see it OK in this photo

Low power tuning? No problem. I used the CW trick (part of the recent Raduino mods) with the 10K resistor but instead of hooking up the other end of the resistor to the raduino, I hooked it up to a

Vince, Thanks for the reply. Yes, i have looked at both methods. But no luck in adding to existing code. I tried using code from Peter Flemming, as he use clk2 and clk0 for vfo and bfo. I built a

U3 should be: Pin 1 - 5v Pin 2 - Ground Pin 3 - voltage in Make sure you test the voltage while the radio is in transmit mode. U3 will not be powered up unless in transmit mode. If you do not have 5v,

OK the kit was made 1987 it came from Howes model swb30 I not got a circuit for it I will see if I can work it out 1you can see fitted in my bitx with vk3 AGC to the left of it 2 photo shows a second

My bitx uses a restive swr bridge was a howls kit from years ago it never let's your pa see more than 1:1.5 swr I run a I.vee dipole with a swr of almost 3 and my bitx worked fine I will post a photo

It was said to change this cap to 4.7uf i did not have one so used a 6.8 uf I find when you key up you get 1 watt of rf for a split second then your audio is OK I was thinking to try a non elec

Rich KC8MWG MOSFETs will blow from over-current faster than I can reach the controls, but I am old and slow so your mileage may vary. Tune up has always been one of my complaints about the BITX

Joe, there are two ways to get USB. The first way is what's offered in Allard's Raduino project which shifts CLK2 to 19MHz. The second way (which I'm going to be doing when life gets outta the way and

Hi, Myself and Adrian (VK4L) have been working on code developed by PD8W. We believe it would be a very nice addition to software choices for our fellow hams. It works with an atmega 2560, a SI5351, a

Whats the details of the C124 mod, and is there a diagram with the modded values for the AGC circuit. Phil - G7BZD

Oh...ok I see it.....nope still a blank screen, but the backlight is on...but the radio is not. Hi...guess somehow I fried the radiuno. I was varying the frequency of the bfo crystal x5, and all the
