I'm finding the uBitx signal/noise ratio on CW to be almost intolerable. ?The background hiss is loud and irritating, and weaker signals get lost in it. ?I haven't tried hardwiring in a narrower

BITX40 ord 2/24/2018, shipped 3/3/2018, sched delivery 3/7 - terrific now for the uBITX ordered 3/1/2018 ):>

This is a non-ASCII code, which suggests that the code had something copied/pasted into it. The error message does a pretty good job of identifying the line number where the error occurred. Go to that

Hi Justin, If you want to change vfo, i think you should check qrp-lab.com for kit to built vfo. Hans Summer make really amassing kits. It Can even be controlled by gps to keep the frequency. There

Did you open the sketch file or entered it with Cut&Paste?? Could be that a <SPACE> was changed to <SHIFT-SPACE> which usually you cannot easily ?distinguish in the editor. Maybe manually typing in

Pictures are correct, wire up diagram wrong ... http://ubitx.net/wiring-up-the-volume-control/ Unfortunately It’s not the only error, see this page on uBITx.net as

Orange to middle lug of the volume control? Shouldn't that be Yellow? That's certainly what the schematic shows. We are talking uBitx here aren't we? If I'm wrong about this you may well have

160 has some kind of contest going on as well as a number of QSOs. 75 is quite busy. Should be able to find traffic on either of those bands. Vince. -- Michigan VHF Corp.

Forgot another important detail: powered by battery measuring 12.6V under load.

Finally got mine on the bench. Just wired up audio pot, encoder with button, tip & sleeve of 1 heaphone jack, power, and Antenna.? Used my N2CQR-designed 160m-capable HPF with the original ceramic

What Vince is proposing is that the stereo jack be wired with the TDA2822 output going to the tip, ground going to the ring, and the sleeve floating (not grounded). A speaker with a mono plug will

While trying to compile the original Farhan BitX40 sketch, I keep getting this error message- *stray ‘\302’ in program?* ive been able to compile many other sketches but can’t seem to get this

I'm with you. The standard for audio outputs on a communications rig doesn't include stereo headphones. That said, the inclusion of an isolating capacitor on the output just makes good sense.? Sent

The bitx40 kit should have come with a ready wound toroid. The coil is 9uH as I remember. Raj

I didn't, nor would I ever tell someone to do that. It's been pointed out in the past that there are errors in the wiring diagram. If it says that, I'd call that an error. I haven't looked at the

If you only get black squares it sounds like the contrast is off. Do you have a potentiometer on the back side of the Radiuno you can adjust for contrast? tim ab0wr "Justin Maynard KN4FAW"

Respectfully - If you wire the positive output of the 2822 to both the tip and ring terminal on the TRS jack and the ground lead to the sleeve terminal and then plug in a mono plug you *will* short

I finished a BitX20 Ver3 some weeks ago and opted to go the analogue VFO route.?After a decent warmup it sits rock stable during a QSO and I've listened in to 20 min ragchews without having to touch
