Release EU1KY AA Firmware CEC Version 0.40 ( How to using WSPR, FT8, JT65 TX Mode)


This version is a development version and may be unstable, and some of the features included in this version may be removed from V1.0, Stabilized version V0.35 has been released, and stabilized version is posted separately.

stabilized version : http://www.hamskey.com/2019/03/eu1ky-antenna-analyzer-cec-stabilized.html

When this version stabilizes, I will change version number to V0.45.

1. Added or improved in V0.34
  Please see the link below for revisions and improvements until Version 0.34
  (Do not download the firmware from the above page. old version)

  Please see the link below for revisions and improvements until Version 0.21
  (Do not download the firmware from the above page. old version)
  http://www.hamskey.com/2019/03/release-firmware-cec-version-021-for.html



1.1 Added speed control function of Auto (fast) mode in Frequency Sweep mode
'PAN AUTO SPEED' has been added to the setup menu. This menu does not affect AA, so you can change it as you like.

You can change the speed when operating in 'Auto' mode in Frequency Sweep mode.
'8' means speed up to V0.34 (Default Value)


If you change it to '16', you can see the value that changes close to real time.
As the speed increases, the measurement interval becomes wider, and the interpolation method instead guesses the value between.

If you set it to 4, the speed will be slower but it will be more precise than the existing one.


Below is an example of setting to '16'.


The measurement is executed in 0.5 seconds or less, so it looks almost real-time.


For precise measurement, stop the 'Auto (Fast)' mode and click the Scan button.

Below is a test video of this function.


1.2 Extend measurement frequency range in S21-Gain (VNA)
I have expanded from the existing 100Mhz to 1Ghz. 

I recommend measuring this function only from 0 to 100Mhz, 0 to -40dB. 
However, because users wanted to see a wide frequency range, they increased the measurement range to 1 GHz. At 100Mhz or higher, measure to -30dB only.



1.3 Added speed control function of Auto (fast) mode in S21-Gian (VNA)
'S21 AUTO SPEED' has been added to the setup menu. This menu does not affect AA, so you can change it as you like.

You can change the speed when operating in 'Auto' mode in S21-Gain(VNA) mode.
'8' means speed up to V0.34 (Default Value)

If you change it to '16', you can see the value that changes close to real time.
As the speed increases, the measurement interval becomes wider, and the interpolation method instead guesses the value between.


If you set it to 4, the speed will be slower but it will be more precise than the existing one.

Minimized blinking by minimizing the newly drawing area in V0.4.


Refresh to 0.5 seconds or less, so it looks like real time.


Test Video


1.4 WSPR, FT8, JT65 Transmitting function
This function can be used for setting up for digital communication, testing the connection between a radio and a computer, and measuring the reception performance of an antenna.

Or, if you add a simple amplification circuit, you can use it as a WSPR beacon.
Please refer to Section 2 below for usage.


1.5 Other changes
 - The remaining balance (%) of the battery was added at 0.34.
(Removed by user's request, added back by user's request)

 - The +200, -200 buttons have been added in the Si5351 Corr setting at 0.34.

 - Added touch function in Quartz measurement function. (When the RX screen is displayed, the user's touch moves to the next step. - user's request)





(When using this function, I have found a problem that I need to set the frequency and change the frequency. We are going to fix it in V0.5
(Be sure to change the frequency and use the function. Version 0.5 will be improved)



 - In the 'Manage Snapshots' view screen, you can select a file name by touch.
 (user's request)


 - There are several other Minor updates.
 (Memory cleanup, Name change 'S21-Gain Calibration', resize and realign buttons in S21-Gain for easy touch 'Auto', Fixed bug that screen turns off in configuration - Sleep mode section, To prevent entering 'Sleep mode' in 'Auto mode' of Frequency Sweep and S21-Gain  and mores...)


2 How to using WSPR, FT8, JT65 Transmitting function

2.1 Change Time
You can use it without setting the time, but if you set the time, you can use the digital mode more conveniently.

touch the 'Configuration' button


touch the 'Date/time' Button



touche the 'ok' on any date
The date is not important. You do not have to match today's date.

Set the minutes. Press the 'OK' button when it is 0 seconds.


Look at the time at the bottom of the desktop and make sure the minutes and seconds are correct. 


Touch the upper button 'WSPR/FT8/JT65' button


2.2 Change Mode
This function can use WSPR, FT8, JT65, JT9 protocol.

touch the upper button 'WSPR', 'FT8', 'JT65', or 'JT9' to change to the corresponding protocol mode.

[WSPR]


[FT8]


[JT65]


[JT9]


2.3 Input data for digital Mode
The data for WSPR is Callsign, Location, dBm

Touch the 'WSPR' button
Touch the Callsign Area

Input Your Callsign.
If you need '/', type '_'. If you have entered everything, click the 'OK' button.


touch the Location Area and Input you Location

input dBm Area and Input dBm


For FT8, JT65, JT9, only the text data to be transmitted is required.
If you enter only one, all protocols will be used together.

Touch one of 'FT8', 'JT65', or 'JT9'.



Input 'Text Message'
Ex) Your call sign  and your location


Save configuration information
Only the 'Save Config' button must be pressed to save the set information to the SD-Card.

Even if the AA is turned off and then turned on, the setting configuration is loaded.

2.4 Send Data
Select Protocol for transmission. (A)
Please select a band to transmit (B)
If you want to adjust the frequency, use the AF-10Hz, AF + 10Hz buttons(C)
WSPR should not deviate significantly from 1500hz.

Transmit option #1
If your 'AA' does not have the correct minutes and seconds, watch your wristwatch and press the 'Manual Send' button if it is time to transfer



The 'Manual Send' button is changed to the 'Stop' button and you can interrupt the transmission at any time using this button.

The status changes from 'Ready' to 'On air'.

Transmit option #2
If your 'AA' has the correct minutes and seconds set, press 'RTC Send'

The status changes from 'Ready' to 'Wait ..', The transmission will start automatically when the time is available for transmission. Please wait a moment.

If you want to stop the transmission, click the 'RTC Send' button again.

If the transmission time according to the protocol is reached, it will be transmitted automatically.


If you want to continue digital transmission, you can use the 'Continuous TX' function.
(D)

Click the 'Continuous TX' button and the square will change to blue.


If you press 'RTC Send' button, it will continue to be transmitted until you press 'Stop' button.

Maybe you can use it to measure the performance of the newly created antenna.


2.5 Test for digital TX
QRP The spectrum when receiving from the transceiver. (Change Frequency)


It has been decoded in Wsjt-X 2.0.



The below is a test video that transmits a digital signal at 'AA'.


2.6 Change transmit port
S1 and S2 can be selected as transmission ports.
S1 outputs a very weak signal.

Touch the TX Power area below.


The TX port and power will change.





It may be possible to efficiently test the reception performance of the antenna by leaving 'AA' at a considerable distance and outputting it to S1.


2.7 Application
You can also use it as a beacon by adding a simple circuit.

I do not know if someone needs PTT, so I added some features. If you need a PTT for hardware retrofit, you can use GPIO B4.
GPIO B4 becomes HIGH when WSPR, FT8, JT65, JT9 are transmitted.

In the above video, there is an LED, which is the LED connected to B4.
This is just your choice. I do not need it now, but I just implemented it because somebody might not need it.


3. Download Firmware


4. conclusion
I would appreciate it if you test and give feedback.
If there is no problem after 1 week ~ 2 weeks test, version name will be changed to stable version.

If you want a stable version, please use the link below.

  3. Tested all the features. Everything works fine. Perfectly!
    In the future, I think it is necessary to compare the design on all screens. Although, to make the buttons the same. Thanks for your work. Not an analyzer, but just a fantastic car. Soon will turn into a transceiver ...... Hi..hi

uBITX Firmware CEC Version 1.08 Release

uBITX Firmware CEC Version 1.08 Release
Version 1.08 is the first major release since 1.061, I will release it after a 50-day beta test


How to upgrade uBITX Firmware

uBITX is based on Arduino Nano. So uBITX's firmware upgrade method is the same as Arduino.
There are two ways to upgrade the firmware of uBITX.

The first is to compile the source from the Arduino IDE, and the second is to upload the compiled hex file using the Firmware Upgrade Tool.

I'll show you how to upload a compiled hex file as a second method.

1.Connect the uBITX's USB cable to the computer.


2.Run Device Manager on your computer.
  The way to open the Device Manager for each OS Version differs slightly.
  In most Windows, you can easily launch the Device Manager by running.

  On your computer, press the Windows key + R.



 Type devmgmt.msc and press OK Button.




On most operating systems, there will be a serial port named Ports with CH340. If so, the next step is skipped.

If the serial port is not installed as below, you need to install the driver.



Included in uBITX is the Adonano, which uses the CH340 USB To UART part.

Download the latest CH340 driver from the Internet.
