Just fixing a secondhand uBITX from ebay. it's a v4 and it's running uBITX v0.20 +v1.200 firmware according to the start up display

I'm puzzled by the bars in the 14th and 15th characters on the top line of the 2 line LCD display (see attached photos).

Are they supposed to be a signal meter? They seem to appear sometimes when a signal is detected but they stay there when the signal drops until you tune away. Or are they for some other purpose?

It's got an s-meter in the chassis but it isn't connected to anything. I'm planning to drive that off the vol high pot eventually.

Thanks for the link. It's a bit of an unknown this box. I got if off ebay and there was lots wrong with it - the speaker had come detached in shipping and rolled all over the PCB smashing a couple of toroids that I had to replace and rewind. Q90 had been replaced by a TO-92 package but it had been soldered in the wrong way round resulting in zero output power. After I fixed that I set the bias and got 10 watts out - just worked W3LL on 20m SSB -?3481 miles !!?

There's a purple wire connected to A7 but it's just flapping in the breeze. I'm guessing it's either picking up noise and/or the s-meter is set wrong in?uBITX Manager - I'll download a copy and have a look once the USB mini-B cable arrives from Amazon. Think I'd rather get the S-meter that came with the case working ( a la ?) so I might just switch this feature off.

Occasionally it displays "ST" in place of the signal bars - any idea what that means?

Thanks for the link.

Answering my own question -?

Looking at ? - I'm guessing ST stands for "straight" as in straight key for CW

Everyday's a school day.

Got a usb2 mini-B cable, installed the?CH340 driver and fired up uBITX Memory Manager. As I thought the s-meter had been set in memory by the previous owner (see attached) and I guess it's just responding to noise coming in through the A7 lead dangling in the breeze. I've now switched it off in Memory Manager as I'd prefer to get the analogue S-meter in the case working instead. I can always switch it back on again
