In addition to being a first rate operator in the 2022 VA QSO Party, Steven is a multi mode operator! My log shows Olivia, Contestia, PSK and the beloved FSKH105 (the finest visual digital mode

No, we had some covid infections! We should ship very soon. The manual is all done, except for the rtty section and the intro. - f wrote:

Hi Ashhar, Any update on when the product will be released ? It didn't go live at the weekend so I guess you are sorting out a few more software issues ? Best regards, Peter.

Will, The critical part is that sbitx is entirely open source. If you happen to have a raspberry pi with you, you can order a wm8731 card for 20 dollars and solder rest of it from ordinary transistors

Wow! I've been away from this group for a while and just saw this -- great job Ashhar! $500 is understandable in today's tough climate, but maybe things will cool off and there will be a price cut in

Ashok, It should not matter if you truly get it to zero beats.? One way to tell is to save the calibration value and then go back and set the radio for the calibration frequency and see if there is a

I have now installed KD8CEC sw in the original Nano, and read out the data using ”MM”, and backed up that file. I now have reception, not as great as a websdr (that i found) but i should test with

Anyone know if PI-3B would work with the sBITX until the prices come down on the PI-4's? Ron

Hi Evan, Thanks for jumping in. Ok I will calibrate using the TCXO, but I have one question. During calibration, which side-band mode should I use, USB or LSB? In the video Farhan used LSB, but in

Ashok, I would suggest that you follow the steps in Ashhar Farhan's video: https://www.youtube.com/watch?v=t6LGXhS4_O8 You can use the TXCO as the AM station to zero beats.? The critical step is the

I reported earlier that Stephen received email notification he won the "Digital Modes, Single Operator" section of the 2022 Virginia QSO Party. The handsome wall plaque he received to confirm the win

Hi, Thanks for the info. Thats great ! ?I Will load KD8CEC sw in the original Arduino… and fetch the data with MM …

Ashok, Does it transmit 1) SSB and 2: CW do both tests. When you test with 7.023 MHz tune plus or minus 1 Mhz or more and see any carrier. If so it may show up something. Resolder all mixer diodes

Thanks Raj, Yes I also thought later that frequency looks like OK, except i think there is a typo on the uBItx block diagram on HFsignal page. Now that the RADUINO is generating correct frequency,

Ashok, Looks OK, clock 2 for 3-30 Mhz = 45Mhz +3 or 30 = 48 to 75 MHz I havent dabbled with these numbers before, but I should think you should get 56.05 or near about not 57 MHz i.e 45 + 1.0556

Hi Farhan, As there is no strong AM station in Kolkata, I cannot attempt the calibration procedure. I have a 20 MHZ TCXO +-2.5ppm. Can I use that to do the calibration ? If yes, what sideband mode

I measured the frequency in 3 clock output. Results below, the accuracy of measurement may be off by a few KHZ? due to low quality counter. There are 4 sets of measurement. SET1 (A=3000 KHZ LSB)

Thank you for the explanation...

Ulf, You need to load the KD8CEC v1.20 software into the original Nano of the Raaduinno for the PC-based Memory Manager to be able to read the EEPROM for the calibration data.? Loading the KD8CEC

Hi, I can’t connect to original Arduino using KD8CEC MM, alwayd getting ”Error Receive Length”, wichever speed I am using…
