Re: site back up

 I will make one suggestion for an ISP..
 Use a linux based server.
 Windows based servers get hacked very often..
 Just a suggestion.

Yes, it has been. We think we are going to have to move the site to another ISP and start over.

I’ve made some progress on the band scope. 

It’s stretched but I’m not sure if it correlates to the range of the slider.  The slider spans about 500khz the smaller lcd versions was less. This was the effect of me stretching the range but I don’t think it matches with the visual reference. But hey it looks good.

This is code snippet you have to touch. The number 5 is what stretched the signal. The number 6 gave the signal more resolution. 

It was originally set as 2 and 3 respectively

KD8CEC 1.2 S meter movement, but no sensor!

Mark Hatch
 

Hi,

Trying to get a working s sensor for KD8CEC. I enabled the analog (A7) S sensor and then turned it on in the ubitx database manager.  I breadboarded one based on a blog post by KD8CEC. Although there is some weirdness (on background noise only, see the sensor level steadily increase to s9), decided to solder it up and see if playing with the capacitor will get a reasonable set of responses.

So here the sensor is completely disconnected, but S meter still enabled in the software. And to my surprise, I start seeing what almost looks like reasonable strength readings. Fired up the Ubitx Database manager again, put it in simulation mode, and the bits read from A7 seem to vary between 20 and 200, generally with the strength of signal. I do have the "front panel board" supplied with my case from  https://amateurradiokits.in/ but as far as I can tell, the A7 pin is disconnected.

My guess is that I am just seeing the impact of noise on the "floating" input.  Any other thoughts?

Yeah...you need the stand alone. Sorry...I thought you were running one.

If you want to fix that, just click on the p1 attribute on the right side (prob in px page) and click on Delete. You were compiling it correctly.

Anyway, here is the new tft. Let us know if it works out.

Hi Kevin,

It sounds like you may have accidently added a picture to the sketch. Let me recompile the hmi @270 degrees and I'll repost. Did you use my hmi or Ted's edited version (bigger tune step buttons)?

Where's this daughter board that everybody's talking about? I went to the website and I see no reference to it whatsoever?

Hi,

Saw this referenced on ubitx.net. How is the project going? Sounds like a great addon. Be happy to be the test subject on a V4 board. :-)

Adding 160m LPF will help a lot.

Can you make the LPF board separate or at last can be cut off?
Also how about including a 160M LPF position?
Guess this would entail software changes, but I am sure that for the excellent programmers in this group it would be just a simple matter to modify the software.

HI Everyone.
I'm working on a nice little add-on board for the uBitx.
It contains:
- 200hz CW Filter
- Mic Preamp (SMM2167 Module)
- VK3YE LED AGC
- LPF section (Dual relay per filter)
I will try do it all TH, but the 100uh inductors underneath will need to be 1206 SMT...

Maybe $5 a board + post (VK-$1, DX-$3)

Here is a prototype picture:

Re: Kit projects AGC install - extremely frustrated.

Looks like a 1 Meg variable R in lieu of the switch might be the easiest arrangement.  Only 2 wires back to the board (C and G), plus variable AGC release time.

An alternative if preferred would be to use a sub-miniature MIL spec rotary switch to switch between  common, off/slow/fast just as in the ND6T wiring diagram.

Just completed this board with no problems.

A screened pre-made wiring loom would help ensuring the exposed sections are kept nice and short. Choose good quality connecting wire and pre-solder the pads before tacking on the leads for best results. This is by far the easiest AGC board design to fit in my opinion.

Best wishes Derek G4VWI.

A rotary switch for AGC timing/control looks like a smooth idea!  Here's a deal for a pair.

Re: bitx40 dumb questions!

Ted
 

The uBitx also runs fine on 15 volts and has a little better sensitivity.... possibly  a matter of perception alone due to increased AF gain. 

Currently running off of a 20 volt Li-Po drill battery and feeding the finals direct, while regulating down to 15 volts for the rest of the radio. Currently waiting for some buck converters to do the voltage step down job in hope that this approach wastes less power as heat.
