Re: ubitx v4 - distortion in received audio

Vic WA4THR
 

The V4 use of discreet transistors suffers from crossover distortion in the audio amp final stage. Raj did some great work identifying this and providing a fix:
https://groups.io/g/BITX20/message/52181?p=,,,20,0,0,0::relevance,,crossover,20,2,0,22188783
I used a 10-turn 100 ohm mini preset pot and it ended up between 30-40 ohms. That completely fixes the distortion.

Re: #bitx20 Ver 5 relays. #bitx20

Raj, good to know advices. I think I may drill a hole on the top of the chassis to have an easier access to RV1 to set PWR to about 8W SSB. You specified 8W on 40m. As my unit barely puts out 2.5w on 10m, my I adjust RV1 to increase PWR without creating a mess? How much may I possibly increase PWR on 10m without creating unwanted QRM?

Re: Ordered my v5 ubitx today, case delivery tomorrow!

David Wilcox <Djwilcox01@...>
 

Another interesting side note:

Had a defective item and Amazon put another in the mail same day. With Prime it CAME IN TWO DAYS....SUNDAY!!!!  And gave me 30 days to return the defective unit.  Yes, I pay for Prime but it’s worth every dollar.

The delivery van had a sticker on the door stating USPS Rural Delivery.  I am not rural.

I thanked the local Postmaster and she didn’t even know about the Sunday service.

The item was just a high quality iron (yes, my wife of 45 years still knows how to use one), not a medical emergency item.

Not so difficult for me to replace relays and other components. But I must admit that this is how I make my lively wood. Am a 2 way radio bench tech for more than 40 years. And that includes SMD as well. Also have a professional workshop at my disposal with test instruments that many can only dream of. And still working at the age of 67.

Many constructors seem really concerned about their rig's compliance.  I think this is probably an unnecessary concern given the power output of the uBITx.  Doing the mods cannot guarantee compliance, but doing both mods is likely to significantly reduce spurs and harmonics bringing it well within the unwanted emissions from a 100w rig.

I suggest that more, clearer data is needed before recommending a particular spurious fix.  The Axicom relays may work if a board does not require a huge improvement - I think this may be why some are not seeing compliance with this solution.  The alternative solution using 3 relays on a daughter board is actually easier for many builders since it has no need to remove relays from the board - but problem is that no one is sourcing it as a kit.  On the 45 MHz fix, I am not sure that replacing two coils is adequate in itself.  We honestly need more data.  Our own local club has a large group build - we can contribute data when we have it on v4.  I don't want the community having a false hope on any particular cure - and also want the community to understand that a sufficient fix is possible.

Re: Nextion Tune Button

Ted
 

Hey, Sam.

On my Zombie Apocalypse Survival HF Go-Kit (work in progress), the front panel has a momentary spst switch that essentially mimics a CW key.  So, I might suggest exploring the addition of a 2N7000 across the CW key line and assign one of the digital outputs freed up by use of a Nextion screen, to turn this transistor on and off (and henceforth use for tuning).  I suppose a virtual key, functioning in a latch mode, needs to be designed and inserted into one of the popular Nextion screen firmware versions to activate/deactivate a certain digital oitput.

Theoretically.........

VK3YE AGC Success in uBITX

Curt
 

With the help of a couple ops here I figured out my wrong integration of this circuit into the uBITX.  I was trying to use it is series with the volume control, it needs to go in parallel.  Simply explained - do not disconnect any wires or parts in the uBITX.  Attach the LDR across the volume control pot as described, and the bias to the 12-13.8 volt DC supply (I wired a SP2T here to experience the difference, honestly I find no need to turn off this circuit).  The AGC 'sense' into the series (nominal) 10 uF capacitor is fed from the center of the volume control, via a series resistor.  I started with this resistor being 3.3k but noticed the AGC behavior varied with the volume control setting - which implies this circuit is loading the main path.  I increased this resistor to 27k and now it works nicely - the volume control acts independent of the AGC sense circuit. 

The result is quite nice with large signals being squashed I estimate 15-20 dB.  I had needed to run the audio gain at about 5% or less to copy these large signals in headphones - now I can routine tune across the band with the volume control at around 25%.  As I also operate a K2 I am familiar with a soft AGC response requiring some operator audio gain adjustment for copying weak signals - but rarely needing more than 50% audio at least on 40 meters.  I am thrilled with how this circuit works.  Two NPNs, an LED and an LDR are certainly within the spirit of the uBITX design. 

A couple parts comments - the LDR has a dark resistance of over 100k ohms and a few k ohms in dim ambient light.  Perhaps the latter may be more important, as in the box it may offer comparable resistance to the volume control.  I am using a small but very bright LED with a clear body but emitting red light.  Reading about photoresistors they are said to have a little lag in their response and it seems to act nicely as I tune across the band or listen to a pile-up of signals of varying levels.  It is a keeper. 

There are several other AGC circuits to explore.  The one in the Jackal seems to be a derivative of the W7ZOI hybrid cascode, albeit simplified.  Worth exploring for homebrewers wishing a more complex circuit to try.  Likely I was misapplying the ND6T AGC.  Enjoy your pursuit of AGC in the uBITX.

Re: ubitx v4 - distortion in received audio

Curt
 

My v4 came with the bfo out of alignment,  which matters a lot more than frequency accuracy. This might cure it. Do listen with headphones before concluding an issue with the receiver. I hope to incorporate an adjustable audio filter and a final audio amplifier before the speaker and headphone jack.

Re: Should I wait to buy a ubitx?

Gordon Gibby <ggibby@...>
 

Well Arv, I didn’t mean any offense either,   

I thought the discussion was about the United States ....

Certain participants were upset at the manufacturers resulting product.   In their minds it did not meet their view of a product they wished to use under  (United States) FCC regulations (I didn’t hear much discussion of any other regulatory body.)

However, being an amateur radio operator has both advantages, requirements and privileges.  

If you wish to use a kit like product such as the micro bit x you can, 
but you may need to, 
and are also empowered to 
improve it!  

It is NOT type accepted (that I know of ).  The manufacturer did believe when producing various versions & does believe with current versions that  it meets/met  requirements, however obviously the user can operate it in a manner so that it doesn’t!  (and the manufacture may have had incorrect beliefs about their bell curve of produced units ) Old time single side band operators often kept a station oscilloscope or monitor going so they could watch their signal and tune their amplifiers for linearity.  Two tone patterns and trapezoidal  waveforms etc.   With commercially manufactured equipment, many amateurs rely completely on the manufacturers representations that automatic level control and other circuitry made this unnecessary.  not always so I hear. 

This foreign manufacturer does not package their  radio completely, and although it may be a little confusing, and people may be upset at some of the language on the manufactures website, it is still basically a semi kit.   

People choosing to purchase such a system might need to know a bit more in exchange for the less expensive option, and might need to do a bit more if they wish to have a specification similar to that of equipment costing six or 10-fold. 

In the United States at least, I think the basic legal user class are amateur radio operators.  I’m not sure if for transmitting purposes there are any other legal users in the United States.   For receiving it should be fine except in Virginia where I hear they will not allow you to try to receive radar signals from the police.   So don’t try to modify it for microwave reception in Virginia!

But that is not what was being discussed in this thread.

And...not all members of this discussion group are licensed ham radio operators.  Some are
electronics experimenters, some are students, some are using the rigs for non-licensed bands,
and some are just curious.  There are a few who might be CB`ers and some who are applying
BITX designs to commercial use.

Boy, howdy am I sorry I started this thread ...  After a lot of research and time invested in the preparation for ordering one let me say that I have in fact ordered my V5 board today via DHL.  My case is almost here, and Iembrace this experience coming up.

Understand  that we Hams come in all shapes and sizes and degrees of aging just like cheese...some are more seasoned than others and some are not able to purchase commercial  products  anymore. Some just want to capture  the spirit of ham radio...either one more time, or for the first time!

Let's all play in the sandbox well together, or at least be supportive of one another. This forum is for honest questions needing honest answers. I believe this radio as hackable as it is, has great educational opportunities for all hams, and is a definite candidate with a few mods of being a totally clean and great radio that can rival some commercial gear.  It takes far less money to enjoy QRP,  as let's say an FT 817 will. I suspect  I will relearn my Extra Class theory much better with this kit, than I did when I passed it a few years ago. So let us strive to embody the ham radio code, helping one another as "radioactive brothers in arms".
