Dear PA3FAT, Take advantage of your courtesy and expertise to request further assistance. In essence I came to almost the end of the job using your sketch for the s-meter and the encoder: ? The

Did you check your subscription settings?? /g/BITX20/editsub ( /g/BITX20/editsub )

John, It may sound intimidating but learning to re-program the raduino is essential. Many improvements and you will want to be able to use them. Here is a link for a previous discussion. I can't seem

If the final transistor IRF510 is using the same power supply as the transceiver it would be possible for the power supply voltage to fluctuate (on the board end) because of the heavy current the

thanks a lot. But I don't have enough know how to upgrade software. Is there any other methods to make it stable? How the FM ing is happening? Is it from voltage? 73ees VU2JON John

v1.01 is the original stock version. Try to upgrade to Aurduino-v1.15.1, download it from https://github.com/amunters/bitx40 It has VFO disabled during TX to prevent FM-ing (and many other

I am using version 1.01 73ees VU2JON John

I am using regulated power supply 13.5V, stable to 0.1V. I baught it just two months ago. Hence I believe it is latest version. It is showing version 1.01 during start up. 73ees VU2JON John

Jon:? What are you using for the power supply??? 73? Bill N2CQR

John, which version Raduino code are you using? In the latest versions VFO tuning is disabled during TX in order to prevent "FM-ing". 73 Allard PE1NWL Farhan. frequency slightly varying during voice

Dear OM, My bitx40 voice is wobbling during transmit. I am using DDS VFO from OM Farhan. My understanding DDS frequency shall be extremely stable. It looks like frequency slightly varying during

I see you fine Jack Joe VE1BWV

Yes, I checked r74-460 ohms. The meter I use normally gives hfe and leakage and actually puts up a picture of the component, whether its a bipolar transistor, fet, resistor or cap. ?In this case it

Terry Several answers in the past few days have suggested that you purchase a package of 50 same frequency crystals from an on-line vendor and select a matched set from that group. As an

can anybody tell me where i can buy a set of matched crystals for the filter terry gm4dso

Jack, Did you have bad thoughts about Big Brother?

It got through. Check your spam folder, maybe? Marco - KG5PRT [email protected]> wrote:

It was the Nano. There was no voltage on A3. Uploaded Raduino 1.15.1 and Etherkit SI5351 v2.05 to a new one, plugged it in, and it came up NOT in SETTINGS mode, and I heard faint morse code, with the
