Thanks Ashhar I'll do that.... On Wed, Nov 10, 2021 at 4:25 PM Ashhar Farhan <farhanbox@...> wrote:

Re: sBITx - Build chain
The i2cbb is a library to bit bang i2c protocol to control the si5351. There is a function in sbitx.c called set_lo that changea the frequency by reprogramming the si5351. You can comment that out along with the si5351v2.c file. On Wed, Nov 10, 2021, 9:52 PM Kevin Wheatley <kevin.m0khz@...> wrote:

Re: sBITx - Build chain
Kevin Wheatley
sBITx application now running! So after wiring up the WM8731 codec as per Ashhar's schematic (figure 6 from the paper) and changing the /boot/config.txt to include: # Enable audio (loads snd_bcm2835) #dtparam=audio=on dtoverlay=audioinjector-wm8731-audio (as per Ashhar's instructions), the application is now running... happy days, I can now start to understand how this all hangs together within the Raspberry Pi GTK environment... Thank you all for getting me this far, I'm sure there will be a lot of questions to follow.... Kevin - M0KHZ On Tue, Nov 9, 2021 at 3:07 PM Kevin Wheatley via <kevin.m0khz=[email protected]> wrote:

Re: V6 Arrival
Hi Dave,

Let me know what you think of it after you get to use it. I have worked on some of the uBitX rigs for other guys, including the V6. I won't be buying a V6 because I already have a V3 with some refinements. That touch screen is not attractive to me (not repulsive either) so no need for a V6. I am betting you will like it. I like having mine here even though I have other gear that I like. 73, Bill KU8H bark less - wag more On 11/10/21 10:53 AM, David Wilcox K8WPE via groups.io wrote:

Net Report 10 December
Joe Bratton
The band was in very good shape this morning and being net control was a lot of fun. We had 27 QNI and I only needed 4 QSPs. All stations were heard here but those 4 were too lite for a reliable copy--those were in MS, AL and TX, close in for me. Thanks, Rich (WGX), David (1E), and Dr. Bob (UCR) for the relay help today. Lots of very nice fall weather reported today, but Ed K1UQE was the winner of the polar bear with 29F and rain/snow in the forecast. Bundle up there Ed! Jim NK7B was close behind with 30F. Chet reported in /MM and was anchored off east coast of Cape Sable with FB weather. Capt. Bob said he would make another Facebook post today of nostalgic pictures of past WW CW Net members. I have really enjoyed seeing those and you need to check them out if you haven't yet, our net has such a rich history of great ops and mariners. Lloyd VE1VEI was on the skype chat today, still in the hospital and is scheduled for surgery in the next couple of days, keep him in your thoughts and prayers for a quick recovery. Hope to hear him on the net again very soon!?
Hope everyone has a great day, thanks for checking in today!? 73! Joe AA5AD? ?

Dear Ramon, ??? GREETINGS. ?????? ??I am very much attracted by your posting in # No 90771 and also the features explained in the you tube video? ¡®ubitx+Raduino32 in action¡¯ . Please accept my congratulations and appreciations. ???????? ?I am having ubitx V6 and I want to install Raduino32 which is having very good desirable functions. I want the following additional details/ clarifications. 1.????? In? the # No 90771, it has been stated that in the ?uBitx v6 unit the original Raduino with Arduino Nano control board has been replaced by a board with an ESP32 microprocessor. The TFT screen is the same as the original uBitx, it is only necessary to unplug the original board and insert the Raduino32 board. ?Kindly confirm no hardware modification is necessary. 2.????? Is any adapter required to plug in the new Raduino32? in the socket of existing Arduino Nano board? ?If required, the details of the adapter 3.????? How to link the signal from Vol. H (detector circuit) ?for ?S meter function? 4.????? ?I downloaded ?software for ESP32 from ?. On extracting the files, there are following ?ino. files i)cat_libs.ino ii)cw_autokey.ino iii)ubitx_keyer.ino iv) ubitx_menu.ino v) ubitx_Si5351.ino vi ubitx_tft320240.ino vii)ubitx_ui.ino viii)ubitx_wspr.ino ix) ubitx_32_20.ino ????? ?Kindly let me know whether all the above sketches/files should be uploaded in the Raduino duly creating necessary subfolders with same names and putting ?relevant files in the respective folders. 5. Is Raduino32 board available at present with all the components soldered as module? 6 Where ?can I get such Raduino32 module? ? Kindly send? the details and help me.

Re: sBitx xtal filter
I did a brute force method. 1. I used a QER filter.? This is an evolution of the Cohn filter that has equal capacitors. It has paralleled crystals in the end points. 2. I started with 4.7 pf capacitors and variable resistors on either side. 3. I swept the filter on Antuino. The bandwidth was too short. 4. I decreased the capacitors to 2.2pf, the bandwidth proved enough (30 khz). I adjusted the terminating resistors to eliminate the ripple. 5. I replaced the terminating resistors with L network to do the impedance transformation. - f On Tue, Nov 9, 2021, 9:19 PM Niels Jalling <niels@...> wrote: Please give more details on how-to calculate (and build) the 40MHz xtal-filter. |

I've just ordered a WM8731 breakout board from Radio Spares (UK) . With any luck this will be here tomorrow.... The fun continues... On Tue, Nov 9, 2021 at 2:32 PM Kevin Wheatley via <kevin.m0khz=[email protected]> wrote: Hi Niels |

Re: sBITx - Build chain

Hi Niels
See attached my current config.txt file... I have commented out the wm8731 line as I don't yet have the codec. If I run a YouTube video I have sound via the headphone jack, so to my mind I have a sound driver installed and running? Thanks for the clues, I must be getting close now?
