Re: uBITX working, question about power, PTT pop, LOUD headphone output #ubitx

Hi Jim,

I also got the kit from India the other day. I have built it in an ex mobile vhf rig aluminium alloy case.
I am not satistied with the transceiver due to the drawbacks you mentioned.
I like to operate CW but hand keying is impossible due to sending errors which I get whenever I try to pound brass.

Polished also the contacts and tried different keys, too. Nothing helps.
Haven't tried SSB because I bought this rig for portable CW operation.

Tonight I even updated the fimware. Got some new items to the menu but CW is still miserable
in spite of the update.
How about "hard" keying of the transmitter? Carrier on all the time and using a PNP transistor as a switch. No hazzle with processor loops or similar.

DipTrace - schematics, PCBs, libraries, etc. all there.

KICAD http://kicad-pcb.org/, it is open source and free. Lots of videos and tutorials online.

Some people like autodesk Eagle, which is of course owned by autodesk. I don’t like it because the free version is too restrictive On the number of layers and board size.

I’ve also heard good things about diptrace, but haven’t used it personally.

I have a software called Auto Sketch that I try to draw schematics with, but it did not come with a symbol library.

I use something called FidoCadJ. It comes with a pretty good library and you can add your own symbols. It's a freebie!

Another Ubitx Case Possibility

 

I know that ammo cans has been used for projects since the beginning of time. Spotted this one at Tractor Supply. This one is all metal, has a nice gray hammertone finished and seems to be about the right size for a Ubitix: https://www.tractorsupply.com/tsc/product/treeline-metal-ammo-can-hammer-finishing-small?rfk=1

Hi my BITX 40 come to me in the UK in
13 days i thought that was great
service and the support from this and
the other BITX forums is excellent just
wish we could get more kits like this.

Re: Variable power control

Very nice and helpful.  I will save this.

So, you seem to be saying that anything under 4.6volts is too low?

Will you system health display show on your current LCD display?  How will it input into the processor?

Thank you again.

Linear Technologies LTspice is a free, powerful and versatile program. You can easily draw excellent schematics and print them
or email them. Many of the schematics you have seen on this reflector have been drawn in LTspice.

Re: Erratic Tuning bitx40!

Larry Smith
 

I had this problem one time and it was the 100k tune pot opened. Just before failure the pot tuning was unstable.
and noticed the wiper action was getting rough.  I was using a cheaper blue Chinese pot at that time.

Hi, my bitx40 has decided to start tuning erraticly! It will tune itself in 10khz steps to the very top of the band or the bottom. And if it’s not doing that then it is jumping and tuning all over the place! One thing I have also noticed is that when first turning the radio on, the Radino with version number displays, it never used to? So I’m wondering if something has reset? Any ideas please? 

Many thanks Carl M0CLS

At 12:45 p.m, the DHL courier dropped mine off at the house in the middle of a pretty good ice storm.  The city side streets have not been sanded or salted and they are slicker than just about anything!  Gotta give those delivery guys a LOT of credit  for even getting out in this stuff.  It WAS a real DHL truck and he was wearing a DHL uniform.

Re: Ownership

We are continously producing now, however, we are not able to meet the demand. Hence, the backlog still remains. I am hopeful that into early march, we will get past the backlog and start shipping ex-stock. 

I am not very active on the mailing list these days because I am heads down, making test jibs, documenting the test procedures, writing arduino code to automate as much as we can. I hope to wrap it up and get back to homebrewing by the end of this week after handing over these jigs and software to the HF signals folks. Some of this stuff is quite neat and of interest to regular builders as well. i will post these circuits and code shortly.

Hey Farhan,

I was wondering.  Do you build/ship uBitx on a continuous basis now or still in batches?  The reason I ask is, I have been seeing people get notified pretty much on a daily basis here lately and have “back timed” to see that there is about a 2 month period between order date and shipping date.  I ordered on January 13th and the last report here you were shipping orders made on December 25th.    Will you continue to ship daily or has the last batch been shipped and we are waiting on the next?  Sorry, but I am just trying to come up with an estimate as to when I might receive my “very anxiously anticipated” ubitx.

 

Thanx for an awesome project!

I thought I'd just mention this here in the passing. When HF Sigs decided to kit the radio, one of my conditions was that they ask for the purchaser's callsign and then verify the shipping address with their address on record at qrz.com. Unless they quote a very good reason, they have refused to ship to other addresses. i know that this is not enough of a cover, but for pirates, it is mighty easier to just buy a second hand marine or hf rig on ebay than try getting a kit from us after two months time and then solder it up.

I agree totally... although I would argue that it's handy to be able to make your own repairs (especially if they're minor, like broken conductor in a mike cord).  I've known some really good hams who were excellent at emergency communications but who barely passed the license exams and who never really understood what was going on under the cover.

Here's another point (where kit building should be encouraged): when I was first licensed, radios were (still) transitioning from tube to transistor... although most of the new rigs were a hybrid of the two technologies (a couple even more advanced than that).  Things have changed drastically since then... and although I am very technically inclined and into homebrew (when I get that extremely rare thing called free time), there are aspects of the modern radios that I am a bit fuzzy about (I work with state-of-the-art tech too!).  A kit can help with that.  I've had some good times practicing surface-mount soldering while building radios - and when doing it you can't help but learn more about the new stuff.

However...

For me, kit building is to relax and take my mind off of the heavier stuff I work with.  One gripe I do have regarding kit building is people who say "here's the threads, start reading.  You have to learn!"  I'm a doctoral candidate working with x-ray fluorescence and optical spectrometry... I spend hours each day just reading and learning.  So when I ask a question while building a kit... I do NOT want to turn something for fun into something more like what I do as a general rule! 

(A polite and concise answer to a technical question or withholding the assumption that people have stopped learning should be the general rule anyway!)

My two cents worth...

Hi,

There's a Zed thread right now, going about 70 pages, about whether Hams really need electrical knowledge, or should have to demonstrate it for a license.

The short version is most people saying "yes they do and yes they should," but a few have pointed out that they've been able to operate radio equipment for decades, contesting and rag-chewing, without knowing how electronics work.  

For that reason, I wouldn't assume that someone lacking circuit knowledge is unlicensed.  It could be someone who has been operating for years in a less technical capacity and who has now decided to take the plunge into kits---and who in my opinion should be encouraged to do so.

Thanks, Xcott K2CAJ
