The Teensy replaces the nano.
Is there a write up anywhere?

Are the adapters commercially available?
Yes, at www.w0eb.com

I'm not a paid shill, just a satisfied customer.  The Teensy speeds up the UI quite a bit.  You must compile and upload the software from Jim's website to the Teensy yourself -- it's pretty easy.  You do have to solder pins to the adapter board, but that also is pretty easy if you take your time and follow directions.

That being said, the CW keying problems have also been fixed for the Nano with Reed's software, but I haven't had a chance to test that out yet and compare it to the Teensy.  I'm still ironing out hardware problems with my V6.

Hello Thomas,

The replacement display arrived today.
Extremely well packed.
Plugged it in, reassembled everything.
I quick test and everything is working.
Thank you so much for your assistance.

I am right behind you Jim... Got my adapter and T4. Just need to glue it all together when my V6  gets here!!
Looking forward to see how this plays compared to my V4..

1 hour to modify (added BCB filter to the RX as I have a 5KW AM station within 3/4 mile of my house). I have the N8DAH AGC board and will install that in a few days after I thoroughly check out the radio.  

Removed the NANO (not going to use it again, ever) plugged in one of my TSW Teensy 4.0 to NANO adapters with a T4 on it to the factory Raduino, re-calibrated it to WWV @ 10 MHz, set the BFO close using TSW's published (in our latest software manual) no-test equipment BFO CAL procedure and made a couple QSO's on 20 meters using a really poor antenna I use for testing.  All checked out very well.  CW Carrier was dead bang on (used my panadapter attached to a K3S which is my main home station) to check it.  Nice keying reports from the guys I worked at approximately 30 wpm with TSW's extra key paddle jack wired in.

No mods to the case or Raduino were made.  The extra paddle jack was mounted in a 3D printed block using a couple of the spare 3mm flat head screws and nuts that come with the kit.  The block attaches with 2 screws and nuts through two of the PA Vent holes and the wires snaked through one of them (between the PA transistor heat sinks).  Very little interference with the ability of cooling air to pass through the vents and allows for "No Extra Holes" in the case.  Gotta love it when a plan comes together.

Pictures include the back of the factory supplied Raduino with the T4 Adapter and Teensy 4 installed/wired up (I did have to change out the supplied USB extension cable for one that had the USB Micro rather than the MINI connector to allow CAT and reprogramming the Teensy 4.0 without having to take the cover off), Back Panel with the extra CW paddle block & jack mounted and a picture of the rig powered up running an experimental version of TSW's latest firmware which has 10 memory channels and PBT (passband tuning) similar to some other software.  This isn't quite ready for release yet, but will be coming down the pike from the Triumvirate Skonk Worx.

uBITX VFO Encoder

Adrian Rees
 

Hi

I would like to buy some of the encoders used in the uBITXfor other projects I have. Does anyone know the make & model ? I want exactly the same encoders because they don't have that annoying click-stop.

Alternatively if anyone has managed to get a proper optical encoder working with the software, I would really like to hear about that.

Thanks

Re: uBITX v 4 Fault Finding:Resolved

Adrian Rees
 

Hi Raj, all

I resolved the problem. Turns out the v4 board I have uses 12MHz crystals in the SSB Filter. I was using v5.1 firmware. V5.1 firmware is for v5 boards which use 11.059MHz crystals, hence a deaf receiver.

Changing the firmware resolved the problem, although it now requires calibration !

Thanks

Maurice,  

you probably have spurious rf carrier on your antenna feed line coming into your radio antenna hookup.  Try putting two or three snap on ferrites on the antenna lead near the radio.  You could also be generating similar signals in the shielded cable lead you said you used on the radio side of the antenna connector.  Try the same solution there.  Also, try touching those antenna leads in both locations to see if there are any changes similar to the ones your having on the mic cable.  It would seem likely there is RF floating around somewhere in proximity to your mic hook up.

Re: BFO Calibration and SSB Carrier Suppression #ubitx #v6

Reed N
 

Hi Evan,

I went ahead and played some tones. 440Hz, and a 1kHz-2kHz sweep. Looks like in both BFO tuning cases, the 440Hz signal is roughly the same magnitude as the carrier, and both BFO tunings resulted in a -70dB average reading for the sweep, although the 11.055.500 had significantly more 440Hz.

I also tried tuning my BFO to 11.053.550 (as shown in my original post), and as you predicted, there wasn't any power when playing the test tones, so it must have purely been the high frequencies of the white-ish noise going through in that image.

Next, I put a test sweep from 300-3000Hz (2s sweep period) into the radio, and found that my output audio signals were approximately the same with the BFO calibrations set to 11.054.700 and 11.060.000. However, at these settings, the carrier was 5dB higher (aka less suppressed) when using the 11.054.700 value. Both of these settings reduced output at 600Hz to around -15dB vs tuning the BFO for maximum pass of that frequency.

Ultimately, it seems that my radio just isn't capable of allowing 300-600Hz fully through without also letting significant carrier through, regardless of BFO calibration direction. I decided to set my BFO to 11.054.700 for now, to suppress the carrier a reasonable amount at the cost of sounding tinny. I can't help but feel that there's got to be a hardware mod solution to this...

On a related note, the v6 schematic says that the filter has a 12MHz crystal for X7. My board's crystals are all stamped with 11.0592, though, so this appears to just be a labeling failure, and not an actual part swap. Ashhar - you might want to fix this.

Re: WA3NFV builds μBITX V6

Dan Mitten - WA3NFV
 

Thanks Reed.

The Frequency adjustment worked very easily, I used WWV at 5 MHz which is strong, here. I can't say that the extra tones they transmit help much! The BFO adjustment required a bit more finesse to get good opposite sideband rejection. I made a transmission listening on my TS-2000 with headphones while the μBITX V6 was into a dummy load, once adjusted. The opposite sideband was all but gone and the rejection was equivalent when reversing sidebands. After tuning across 40 Meters, I noted that the great fidelity that I had experienced prior, was retained.

The carrier adjustment and the VFO adjustment are clearly independent, as I see now, neat and very helpful. The 2.1 KHz offset was apparently just another coincidence!

I was completely unaware of the BITE (Built in Test Equipment). Was I alone?

Ashhar, many thanks to you, too.

All is right with the world!
