The alignment procedure you have it is not for the factory software, so it will not work. Ion VA3NOI

Most Dlink router wall warts are capable as they are 12V/2.5A

Your uBitx V5 uses a different IF frequency (11.059MHz), so your BFO frequency should be lower than that. 11,996MHz BFO frequency was used in V3 and V4. Those two previous versions used a 12MHz IF. Th

Hi Bill! I think you loaded the wrong version of the firmware. It looks like your firmware is for the older versions. Did you use a hex file and uploader, or you compiled the sketch yourself? Look aga

You can use BFR106, available at Digikey. Same foot print, almist same performane for low signal. Ion VA3NOI

Mark, The 0.1 uF capacitor goes on the tuning pot between wiper and GND. you can add a 100 pF capacitor in parallel with L7 to reduce the second harmonic.

At this point I would like to propose a solution. What about us, as a group, contribute with $1 each and hopefully are able to reimburse your purchase. The moment you collect the money you paid you st

Or, one can connect the anodes direct to RX/TX lines and use a single resistor from cathode to GND. Ion VA3NOI

I think that your uBitx thinks you are not calibrated. There is a function of the software which is entered when you have the encoder switch depressed during power up. Did you install capacitors on yo

Adam, The microphone is polarized. The switch you had received is connected between PTT line and GND and not in series with the microphone. The microphone is connected between GND and Mic input. On th

Sorry, the postage was $8.50, total cost was $11.50

I made some AGC boards for myself. Both TH and SMT. They use Don's schematic but a different layout than Kees used to offer. They come in panels of 10 TH and 12 SMT. One panel is $3 plus postage. Post

Michael, Now that you are on frequency you can adjust again the BFO. BFO frequency differs from unit to unit depending on the filter passband. If the pitch on receive is too low you should increase yo

You are missing a second, calibrated receiver on which you should be able to listen for zero beat. Try uploading Ian's firmware ( www.hamskey.com ) and you will do zero beat on your uBitx receiver usi

Michael, I do not know what number you shall write in uBitx manager calibration field for your particular clock crystal (25 MHz crystal for SI clock generator). Why don't you try calibration using the

Michael, You found the right BFO frequency as 11997200. At this point I would leave the uBitx manager aside and go to enable setup. Verify that your BFO is still 11997200 by going to Set carrier. If n

#arduino #ubitx #ubitx-help

Mark, If you do not require calibration to a standard I would suggest you set your lowest value (mine is set to 2) and your highest value (you measured S9 at 50 uV in that gives you 1.6 V) at one thir

Hi Michael, Here is my calibration saved with the help of uBitX manager. You can try loading it. I do not have a factory settings files as I replaced my Nano. You can get the factory values by uploadi

I will explain what I did and it worked for me. Turn ON the radio with the function (encoder push button) pressed and hold it. Watch the screen for messages to reset to factory defaults. Last thing it

Hi Michael! What firmware are you using? In case you use Ian's firmware I will tell you what I have done to get my uBitX calibrated. Please let me know and I will try to help. 73,
