Is there anyone in Maine, USA that would be interested in a couple unassembled BITX40s? I have two kits. I was about to assemble but have decided not to. I'll make a local person a really good deal.

Vic,

I understand that the specifics are for the Bitx40, however some of the comments were that it was used on commercial rigs to protect receiver front ends.  Would be interested in the reason it would not apply to other rigs inputs, as long as it was only in the receiver path from the antenna to the first mixer.  There is Q90 in the uBitx that is possibly vulnerable to the overload problem as in the  Bitx40 Q13(?).

Thank-you for the response

Re: suggestions for a graphics display

Lawrence Galea
 

Farhan
good thinking.
However, I would suggest not to use the small displays as it will be difficult for most of the old timers to read.
Balance the size with cost
Thanks and regards

Among the various experiments, and understanding the requirements set by Farhan I can suggest these two options: 1) 0.96 - 1.3 inch IIC Serial OLED Display 128X64 I2C SSD1306 2) Nokia 5110 84x84 pixel display.

3) ILI9341 display driven by additional arduino nano. The first two have wholesale prices of a couple of dollars, and are simple to use and program. Obviously if you need something better (colors etc ...) you need other displays but the problem is the inability to exploit it fully with the arduino 328p. Possibly you could build an "intelligent display" using a 2.2-inch SPI display and 65000 colors ILI9341 driven by an arduino that exposes via liea I2C serial commands "similar to the nexion" towards the main arduino on which the Raduino code runs. This way I think the costs could go: $ 4 on the display and about $ 2 for a dwarf arduino.

TSW's Raduino "Clone" and BITeensio Kits

Jim Sheldon
 

The TSW (www.w0eb.com/Page2.html) group has confirmed that both our "Raduino Clone" board and the BITeensio board kits will work fine with the new uBITX Version 5 rigs.

The Factory V5.1 Raduino firmware from GitHub works in the NANO on our "Clone" board installed in a V5 uBITX just like it does in a factory supplied Raduino and we are very close to releasing firmware for the BITeensio that will run on both the legacy (V3/V4) uBITX and the new V5 uBITX boards as well simply by selecting VL (legacy) or V5 in the calibration menu. The default will be V5 but to use it in one of the "Legacy" rigs, select VL and calibrate it. The VL calibration info is saved separately from the V5 info and once you have the BITeensio calibrated for both versions you can swap it between the two uBITX types simply by selecting VL or V5 in the Calibration menu.

(If you install the BITeensio in a different V5 or VL uBITX than it was originally calibrated in, you may have to touch up the calibration.)

Beta source code usable with both the 2.8" and 3.2" color displays will be posted in the TSW website's file directories sometime in the next several days as soon as the operating instruction manuals are revised. The same version will work for both displays with the addition of one wire on the 2.8" display only. On the 2.8' the T_IRQ pin needs to connect to D17 on the Teensy 3.6.

Hi All.
How about doing a Pacific Region QSO on 7.177?
Time of say 8:00 PM ( 20:00 ) Australian Eastern Time  =  10:00 AM (10:00) UTC SUNDAYS?

Yeah nothing heard I did call cq bitx quite a bit. Did have 4 qsos with the bitx curious. Talked to one guy in Baltimore who gave me a solid 59 and couldn't believe that I was running a qrp power level. Last week talked to a ham in Green Bay, he asks, "you running power or just a 100 watts?" .... ah 10 watts. He didn't believe me. I hear stuff like that a lot.

My good antenna has been on the ground for a week now from ice.

Knowing that the radiuinos are compatible is good news Jim. Thanks for posting that.

Have you had a chance to evaluate the v5 board in other ways. Showing power or other factors that might be significant?

Re: TSW's Raduino "Clone" and BITeensio Kits

Jim Sheldon
 

Dave (and All),
Right now I haven't had the opportunity to do any more than get the cards (and with the immense help of Ron, W2CTX, TSW's master programmer) evaluated with the system to make sure they work and that software can be written. We didn't bother writing the software for the Raduino Clones as we supply them already containing the HF Signals/Ashhar Farhan factory versions. We used Ashhar Farhan's V5.1 posted on GitHub to check things with the V5 board and it works just fine - RX sensitivity is really good (better than claimed for the V4 (.2 microvolt signal is readable claimed for V4). Once I had my first V5 board calibrated (using the original Raduino that came with it) I was able to copy CW signals down on the noise with a very poor antenna I use for evaluation. I did NOT measure the sensitivity yet.

Power output was 10 watts on 40 meters (the only band transmitted on so far) and I'm waiting on a brand new Siglent Spectrum analyzer my wife ordered for me as an early birthday present to get here (not shipped yet, hopefully today) before I do any real deep testing for harmonics, spurs and the like.

At present (took time out to write this) I'm re-writing the software operating manual for TSW's BITeensio board and then I'll post our latest beta software to the TSW website. As of this morning, we have only one version of software for the BITeensio but that version will allow use of both the 2.8" and 3.2" ILI9341 color TFT touch screen displays (sorry this is the largest screens we will support right now and they are NOT repeat NOT Nextions. Here's the nice part. This software will allow the use of a mouse and keyboard for control as well as full CAT control (we have a remote control program available on the website). The programmer's reference manual is on the website. We use a partial version of the Kenwood protocol for basic control with many uBITX unique commands/responses (listed in the programmer's reference) that the user will have to interface to their own software.

I've tested this with the N3FJP logging programs (which I use exclusively) and it will grab the frequency and mode from the radio into the logged QSO's.

The mouse and keyboard can be either wired or wireless. Due to USB host library problems from the Teensy USBHost_t3 library, it doesn't like some USB hubs so you can only hook either a mouse OR a keyboard up as of right now. Logitech wireless KB's with the self contained touchpad mouse do work giving both KB/touchpad capability.

OH, I forgot to mention, the new BITeensio software has built in support for BOTH "Legacy" (what we call V3 & V4 boards) and Versioin 5 (V5) boards, selectable through the SETUP/Calibration menu. Calibration constants are saved in different locations so once you have it calibrated for both versions, you can swap the board between either version (as long as you use the same Legacy or V5 rigs you originally calibrated it for. If you move it to a different card, you may have to touch up the calibration again due to internal differences on the uBITX board(s).

Now, back to finishing the manual so I can post the latest (beta) version of the software and documentation on the website this morning.

This makes sense for European ubitxers too.

TSW BITeensio Card - new Firmware published #ubitx

Jim Sheldon
 

All,
The Triumvirate Skonk Worx (TSW) just published our latest "beta" 2.8" or 3.2" Color TFT touch screen firmware for the BITeensio controller card.  This new firmware addresses the changes Farhan made to the uBITX in the release of his Version 5 transceiver board which HF Signals is now shipping. 

Using our BITeensio card and the new firmware you will now have the capability of selecting operation with either the older V3 and V4 uBITX boards which we are calling "Legacy" boards or the new Version 5 ones via an item in the "Calibration" menu.

Depending on which type of uBITX you install it in, you need to calibrate it one time for that uBITX board.  Calibration data is stored on the BITeensio's  Micro SD card in different locations for the 2 different versions so if you calibrate the card in a V4 (or V3) radio, and later decide to switch it to a V5 radio, you will have to again calibrate it for the V5 system.  However, once that has been done, you can then swap the BITeensio back into your original "Legacy" radio, select "VL" in the calibration menu and it will recall the previously stored calibration data for that version.  If it's the same VL board you originally used for "VL" calibration, you should not have to re-calibrate the card.  If, however, you install it in a different uBITX than the original one, you may have to touch up the calibration to make things sound right and operate on the right frequency.  Same is true for V5 boards.

Since both of the displays we use (2.8" and 3.2") use the same ILI-9341 controller, and have the same number of pixels, we found that no software changes were needed to use either display.  No user action is required to switch from one to the other except to make sure they are cabled properly and this is outlined in the manual.

The operating manual for this software has been completely re-written to reflect the changes and the pictures have been changed to show the operating information in the new version.

You can find complete information on this (and our other items) on the TSW website ( www.w0eb.com) .  If you visit the site, be sure to clear your browser's cache on each page to make sure you are getting the latest information.
