Maybe sometimes there is a nuance between agc and avc from the tube aka valve days. Its rarely as easy as it sounds. In a modern receiver like the ubitx, gain is minimized until after the xtal filter.

Hi Ashar, I succeeded in building the sbitx software from your repository on a RasPi-Zero on a recent/fresh copy of Raspberry Pi OS. The building went rather smoothly and had no errors but took like

Answering my own question - Looking at http://www.hamskey.com/2018/05/ubitx-firmware-cec-version-108-release.html - I'm guessing ST stands for "straight" as in straight key for CW Everyday's a

Re-read question. High-pass filter is the BCI cure. AGC or AVC is kinder on the ear. 73!

Question: AGC or AVC? AGC is automatic GAIN control - that cuts the gain of the incoming signal to knock back overly STRONG signals. AVC is automatic VOLUME control - that cuts the gain (usually of

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

Hello Peter, I’ve been trying to reach you via direct email about the boards I shipped and haven’t heard back. Perhaps my messages are getting caught up in spam folder? Best, Jim KM4TXR

Don, To get to the v6 menu you press and hold in the encoder for 10 seconds or so until the settings menu comes up.? You then use the encoder to select the CW Keyer and then press the encoder to

Don Email me direct and we could brainstorm on antenna. My call at yahoo. Its summer, but bands aren't that dreadful overall. Ubitx not my favorite cw rig, still I have made hundreds of cw contacts

“Using” V6.1. Between the menu issue and the limited space for an antenna, and dead bands, I have not been having a good time. Thanks. Don

Hi Don, Which version of uBiTx do you have. and are there any modifications from stock? Most versions with stock displays are as Curt has stated.? You change settings through the encoder (tuning

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

Press the tuning knob and then as you turn it you should see various menus. To select a topic press again, then you can scroll through the settings. If all else fails then find a YouTube video. My

Thanks. But Where is the menu?

There is a menu setting for choosing keyed or straight key. Step through menus, press the main tuning know to get there, and you will see things to adjust. I mostly use my ubitx on straight key,

When I plug in a straight key, my uBITX transmits a series of dots as long as the key is plugged in. How do I get the reg to properly see a straight key? KD7QW Seattle

OM Abhrajit Wonderful news that alignment addressed it. People here will debate agc forever, it works fine without it, but I added a simple LED and photoresistor agc circuit that helps when tuning

Something from long ago … the first time I installed my shack at this QTH in about 1990, I put up a sky wave loop for 80M. Surprise, the 50kW AM BCB station a couple of miles down the road — on
