well after updateign firmware as stated before I lost 2 vfo? boards . so what I neeed is if anyone is not using thier vfo and moved over to a differaant vfo thay would be will to part with the

Dave, this is because semi QSK is ON. Press the CW key down to automatically switch to CW, Press PTT to automatically switch to SSB. This behaviour will be disabled when you set semi QSK to OFF. 73

On the panel it comes with that's more like 3 or 4.

I ran across this video on YouTube last night, interesting work you are doing there. I am (im)patiently awaiting my uBITX with the same goal of creating a self-contained JT9/FT8 rig. Have you

With an I2C expander, the TX_A, TX_B, TX_C and CW_TONE lines could be implemented freeing up 4 digital I/O lines.

Hello, I am very interested in purchasing one of these! Somebody here from Latin America that can give me some advice about the delivery in your countries? Should I opt for the DHL delivery? Thanks in

I'd avoid anything with that low of a bandwidth. Shoot for a minimum of 100MHz bandwidth. Digital is nice, but if you're troubleshooting an analog circuit, such as the IF in a BitX, the signal is

I started collecting Tek scopes (and quit) 30 years ago.? I still have several.? I got 2 of the nice 50MHz dual trace that I fixed for sale. They had some matched transistor modules that would go

Hi all Just completed the mods and installed V2.03 of the firmware on my BITX40, a vast improvement over the original firmware and it's working well. I only have one problem. When I first switched it

Bill :? I am using "Spectroid" which is free. It works quite well and was very useful in setting the BFO frequencies on my BITX40? running Raduino V2.03. Cheers Michael VE3WMB

I don't have the original in front of me but my design is as follows outer layer is 193mm x 63mm x 1.5mm inner layer is 183mm x 53mm x 3mm both have a .33 radius on the corners

?maybe he could measure those two oscillators with a communications receiver and come back with some numbers and we could verify your hypothesis? ________________________________ Sent: Wednesday,

Farhan has said that the uBitx uses a low side BFO, below the crystal filter passband, because with a BFO about 3khz higher on the high side of the crystal filter? the harmonics of the 12mhz BFO beat

Joel first, thanks for using my firmware. Master calibration and BFO Calibration in version 0.27 are the still original source. I also experienced similar problems with uBITX at the beginning of

I ordered mine on 15 December.. I have been told (yesterday)that in my case it should ship within the next two days. Sent from my iPhone

I found the following on mine: Outer 1.35 Inner 2.25 Groove on shell 2.45

there was a problem of no toroids, but they received some on the 1-13-2018 the Ubix should be shipped by the end of this month. that's what they told me.

Doug, I'm doing something similar, but without an original in front of me (it's still in transit). I would like to print mine, but of course I want it to fit when the case gets here. It looks like you

Any word on the cutoff for Round 2?? I ordered mine 21 December 2017 and paid for the DHL.? No word, yet, on when it's going to ship. -- 73 de W5NNH

Hi Ian, I have been using .027 for the last week or so and have had no problems until I tried to calibrate the frequency, the radio goes off into la la land and the only way to recover is to reload
