Exciting Announcement for the uBITX experimenters and tech savvy types:

Now available for ordering, a brand new, completely redesigned, Raduino Clone kit (only for the uBITX Version 6 at this time) that uses the latest PJRC Teensy 4.1 which is much larger and has way more I/O, almost all of which is accessable on the main pins. Hardware will allow USB Host mode (an additional cable MUST be added and the case modified in order to use this but once this is done, a standard USB 2 or 3 hub can plug in and allow a keyboard or mouse to be plugged in for control and operation. The Keyboard can also function as a really nice CW keyer and still allow the keyer paddles or a hand key/external keyer to be plugged in at the same time.

Due to limitations of the "Host mode" programming library (still the same one as the old Teensy 3.6) to simultaneously operate a mouse with a keyboard hooked up via a hub, both must be of the wired type. There are inexpensive wireless keyboard/mouse combinations available (I use one from Amazon) that use only one plug-in "dongle" to handle both the KB and Mouse. All the ones tested so far allow simultaneous KB/Mouse operations so for portable ops this will probably be the best option.

We do have preliminary software for the Teensy 4.1 Raduino available in the "Program & DOC Files" directory. It only allows Touch and Keyboard operation right now but hopefully the next release will remedy that and really make this thing super handy. Almost all of the I/O pins of the Teensy 4.1 that are not directly used to directly control the uBITX and Raduino are available via DuPont style header pions on the back side of the T4.1 Raduino so the experimenter has access to everything available. Plenty of digital and analog inputs/outputs to keep you busy for a long time developing things for this board. (The TSW team is working on quite a few things and all the programming is and will continue to be "open source" with the caution that if you modify it, you are on your own for troubleshooting problems you create. The TSW team simply will not have the time to sort out your source code errors so you will have to do that yourself. That being said, we WILL be available to help with problems discovered in our own software.

A bit of the history for this development:
Shortly after the HF Signals (India) uBITX transceiver Version 6 hit the market, the TSW group produced a Raduino Clone for it that could use an Arduino NANO like the factory version did and operate with the factory's software or, with an adapter also produced by TSW, use a Teensy 4.0 by PJRC in place of the NANO with our own software for much faster display updates, easier calibration and much better Iambic keyer CW operation.

We had good success with the Teensy 4.0 using the adapter, but when we tried to mount the Teensy directly on a custom Raduino board, for some reason we could not make it work right so abandoned that project.

Fast forward a few months and PRJC has made available a new, larger footprint version of the Teensy called the Teensy 4.1. After looking at the specs, the TSW team decided to take a chance and make an experimental attempt at using this on a unique Raduino clone that used the T4.1 plugged directly into the redesigned Raduino board, with no adapter. We chose to mount the T4.1 upside down on the back side of the board just like the original NANO and our T4.0 adapter did to keep the MPU from interfering with the display as well as for accessability.

We had a very limited run of prototype boards made to test the idea and much to everyone's delight, it worked very well! An added benefit of the re-design, is that it seems to have eliminated most if not all of the noise problems inherent with the Factory (and our earlier clone) Raduino using the Teensy 4.0 to NANO adapter.

Except for the very small Si5351 clock/vfo IC, we chose to use all 1206 size SMD resistors and capacitors to make kit construction a bit easier for those who don't like to work with the smaller 0805 surface mount components TSW uses for our other kits. It was also decided that all the TSW Raduino Clone kits would already have the Si5351a IC already soldered in place and checked for proper connections to ensure the highest probability of successful kit completion and operation.

The MPU for this Raduino Clone must be a PJRC Teensy 4.1 and like the NANO on the Factory Raduino and Teensy 4.0 on TSW's adapter, The Teensy 4.1 will plug in upside down on the back side of the PCB. The photo below shows how to set up the (user supplied) pins on the Teensy 4.1 to plug into its socket on the T4.1 Raduino Clone. (There is an extra user supplied memory chip shown on the Teensy 4.1 in the photo that is not necessary and will not be used.)

We strongly recommend that you obtain and use gold plated pins for mounting your teensy and for the 5 pin headers on the back of it. This will help increase reliability and decrease any succeptability to corrosion that could cause intermittent connections later on.

WARNING: You MUST cut the indicated jumper on the Teensy 4.1 due to the fact
that the incoming 5 Volts from the USB programming connection will conflict with the
5 Volts powering the Raduino (and subsequently the Teensy 4.1). Since they are
from different sources, they will not be exactly the same voltage. This could
very well destroy the Teensy 4.1 AND even the Raduino in worst case situations.

A preliminary, working, software version IS available now in the "Program & Doc Files" directory (use the Teensy 4.1, not the 4.0 version). Extra features will allow for a wired Keyboard AND Mouse to control the display in addition to the Touch control already implemented. The keyboard will, in addition to being able to control most functions of the uBITX, also operate as a Keyboard CW keyer. Mouse control has not yet been added but is being worked on as of this writing. Once available, it will be announced on this website.

These "extra features", if you choose to use them, will actually require a modification of the uBITX case to add a USB "A" cable connectionon the back panel. The right sized cable is actually available from PJRC.com for around $3.00 plus shipping and you can order it at the same time you order your Teensy 4.1 if you like. The cable plugs into the 5 pin "Host Mode" header on the Teensy 4.1 itself and allows for a standard USB "A" style keyboard or wired mouse to be plugged in. At this time, you can also use a USB 2.0 hub so both Keyboard and mouse can be connected simultaneously. For some reason we are having trouble getting it to work reliably with combinations of wired/wireless devices at this time. There ARE some nice alternatives. Fairly inexpensive wireless Keyboard/Mouse combinations using only 1 plug-in "Dongle" are available and all that have been tested so far allow simultaneous keyboard AND mouse operation so this may be your best option.

You do NOT have to have the additional cable to use the software, you just won't be able to use a keyboard or mouse for control/CW keyer so it's a matter of personal choice whether or not to modify the case for the extra USB connection.

We are NOT, repeat NOT going to have a software CW Decoder implemented. We firmly believe that electronic morse decoders make too many mistakes when band conditions are even slightly noisy and if you cannot properly copy callsigns, you shouldn't be using a decoder. This decision is final so please don't ask for the addition of a Decoder feature.

An announcement on the BITX20@groups.io reflector, in the uBITX group on Facebook and on this website has been made and the kits ARE available right now as well as software to make them work.

Thanks a million for your interest,

The team.

The assembled, plug-in battery socket will be part of the kit but
the battery itself is user supplied.

uBITX V6 Teensy 4.1 Raduino construction manual.

A comprehensive analysis of the current parts cost (some cheaper/some slightly more expensive, plus labor to install the Si5351a chip) and slight postage increases by the USPS puts the price of the new TSW V6 T4.1 Raduino kit at the same $35 as our older V6 clone shipped in the US. International kits will be USD $35 PLUS international shipping and the total price will be agreed upon by both parties prior to any international orders being approved. Sorry, but under current world conditions this is necessary to protect TSW's interests. International postage rates are changing too quickly and we simply cannot absorb any VAT/Customs duties or replace items lost by other countries postal systems.

The TSW V6 Raduino Clone KIT can be supplied as a bare board for $10.00 post paid in the US. Due to postage increases, the cost for the bare board to those outside of the US and its posessions will be $20 USD and only 1 per order (International First Class "rigid" envelope).

Also available is a full kit of parts with the Si5351a IC already soldered in place and continuity checked, $35.00 post paid to the US and its possessions. For our Canadian friends, the full kit will be $35 USD + shipping. (Canadian Customs/VAT will be the recipients responsibility). For all other international orders, the price for the full kit will be $35 USD plus shipping and must be agreed upon by both parties prior to any kits being sold internationally. Also, any Customs duties and or VAT will be the responsibility of the recipient. TSW cannot be held responsible for these.

Kits are NOW AVAILABLE for order - email W0EB via the link at the bottom of this page for further instructions on ordering.

Preliminary software is available in the "Program & DOC Files" section under "TSW T4.1 Raduino Software" and the software operating manual is available here for download.

Check back often for further updates please.


For reasons I'd rather not try to explain here, I can't put PayPal order links on any of these pages. Sorry for the inconvenience, but all you have to do is follow the directions and contact W0EB via this or any of the other email links on these pages for ordering or further information.


COVID-19 Statement:
During this time of world wide crisis, we at TSW are finding that many countries either are not accepting mail for delivery or are or have implemented draconian VAT and Customs duties on even the simplest and most inexpensive items. This makes it very difficult for us to ship things to Europe at present. We do so only if the requestor is willing to accept the responsibility for his/her countries possible VAT/Customs charges and or non-delivery. We simply cannot afford to replace items lost by another country's mail service - Order at your own risk.
