Did you check the micro switch to be sure it isn't always closed?

On my V4 board there was enough drop when I plugged the mic in to cause the uBitX to cycle in and out of transmit. The internal Arduino resistor was not up to holding the 5v signal above the keying threshold, which I could monitor using the KD8CEC software. I added an external 5v dropping resistor and have had no issues since.

Sounds like the connector is failing.

Re: Gordon Gibby Digital Interface

 

Trust me its not by choice on the manuals. The site layout/opencart that I use will not let me post the manuals I have to link them to sales. Its also why I say send me a mail and I will send them out. I have sent Dennis the info and Curt if you would like it let me know at n8dah@... and I can send them over. If I could post them on the product page I would but opencart will not let me.

Jack I like the way you implemented changing frequency steps right there on the screen, it is clean and efficient. I hate to have to dive into menus to fine useful functions that I use frequently, and changing tuning steps is one of those I use on my other rigs.

Agree, and I have some interesting things I want to try with the 4.0 Teensy. For a while, JackAl used a software timer to track the rate at which the user was "spinning" the frequency knob. If the rate when above some user-defined threshold, we upper the increment factor by 10x. It worked fine, but seemed awkward to us. Because we use a touchscreen with the JackAl, we just put a "floating" cursor above the current frequency (shown here above the '3' digit) and the user can tap the '<' or '>' to move the

Hey Jack!  Easier?  Sure, ok.  But its not always about what easy, is it.  If it were, we would just buy all of our ham gear and be done with it.  That being said, whats mentioned above isn't that difficult.  I used and attiny85 that I programmed with the ArduinoIDE.  Works like a champ.  The one thing I would love to add is, when I change the step size in the uBitx, I would like to have the radio change the divisor on the fly.  For 10 Hz step, divide by 2, for the others by 4.  The goal would be for about 2.4 kHz span per one knob revolution when 10 Hz is selected, and about 12 kHz when 100 Hz is selected.

My reasons for going to a higher PPR optical encoder over the mechanical encoder that most use was all about the feel.  Most optical encoders have bearings and makes for very smooth operation.  The encoder in my uBitx is 128ppr and the Nano just isn't up to that task.  It could likely be made to work but I'm no expert with the code or ISR's.  I also have the BITeensio board and I can tell you that with its Teensy 3.6 processor and  a few simple mods to their encoder routines, I was able to read my 1024 ppr encoders (overkill for sure) as fast as I could spin it, without missing a beat.  Point being, we really need a faster processor in the raduino, something like the Teensy 4 would be pretty interesting.  The Teensy 4 could open the door for having some fun with digital audio filters, better spectrum display, etc.

Re: uBITX rotary enconder

John Scherer
 

It just came to me that, the circuit I posted above and designed by Glen - VK3PE, would be super easy to modify to have two different division ratios.  Rather than using D0 as a direction output, just configure it as an input and have it divide by 2 if its high, or 4 if is low.  Divisors could be anything but you get the idea.  The all I would need is an output from the teensy / nano to reflect the step size chosen to flip the bit

Re: uBITX rotary enconder

I always liked that screen layout Jack.  UI design for these small displays, well any display really, and especially when its for the masses, can be an exercise in futility. Its hard to be all things to all the people ;-)  But this layout puts everything you need all on one screen.  Simple and sweet.

Here is the explanation of the v5 spurs and the v5 solution.  Not that in this thread, Ashhar has not yet gone to the BFR93W devices for the 45 MHz IF.

Re: BFR93w availability in US

I am also thinking try everything else first. If and when we establish a best recipe for curing v3 and v4 mixer spurious, maybe some of our merchants in various spots in the world could kit the parts, perhaps. Or maybe you have tried all those? But I see more signal might reduce the spur level when it sneaks in after this amplifier, if is really needed.

Hi David,
Can I get on the list for the next batch? Also, I tried to download the assembly manual from your store, but cannot access it due the the product being out of stock. Would you be kind enough to email me the pdf file.

Vince,

There are 2 versions of the CEC software for each of the display types.  The difference is one uses a seperate I2C connected Nano to add functionality.  The other uses the spare input pin on the Nano to connect the S-Meter. Read the FileNameInfo.txt file to insure that you use the correct one.

http://www.hamskey.com/2019/04/release-cec-firmware-v1200-for-ubitx.html


The added hardware sensor for the direct connected S-Meter is in this article on the HamsKey web page:
http://www.hamskey.com/2018/06/creating-simple-s-meter-sensor-for.html

If you add a second Nano then this is the article on how to connect it:
http://www.hamskey.com/2018/07/standalone-signal-analyzer-i2c-type.html

If you go the rout of adding the I2C connected Nano, then there are other functions that can be added beyond the S-Meter.  As Werner suggested.

So the choice is yours.  That is the beauty of the uBitx and the great additions that Dr. Lee (KD8CEC) have provided.
