+Quisk Version 4.2.55  October 2026
+==================================
+Karl Heinz, K5KHK, provided a patche to fix the AC2YD remote control head. He provided another patch
+to fix Hamlib control when using WSJT-X improved. He added a mic jitter buffer to the remote control
+head so it works over WiFi. Thanks Karl!
+
+Quisk Version 4.2.54  August 2026
+=================================
+Quisk can now accept audio samples for Tx from TCI at rates 48000, 24000, 12000 and 8000. Please test.
+
+Quisk now includes program icons in the directory "quisk/icons". The Windows icon is quisk/icons/quisk.ico.
+On Windows, right-click the desktop icon and change the icon to <path-to-quisk>/quisk/icons/quisk.ico.
+The Linux icon is quisk/icons/quisk.svg. On Linux, change the quisk.desktop file to
+Icon=<path-to-quisk>/quisk/icons/quisk.svg.
+
+Quisk Version 4.2.53  June 2026
+===============================
+I added TCI support for Software Defined Connectors CW skimmer. Please test.
+
+This version of Quisk now works on Python 3.14 and higher. I changed to a new build system because
+the old one has been deprecated by Python. They no longer support running setup.py.
+The Linux version has a new makefile. The Windows version is installed by pip as usual.
+Please test.
+
+Quisk Version 4.2.52  May 2026
+==============================
+This is a fix for various TCI bugs. Please test with WSJT-X and let me know if all problems are solved.
+It is unlikely that other digital software will connect without problems, but please test and let me know.
+
+Quisk Version 4.2.51  May 2026
+==============================
+This version can use the TCI protocol to connect to WSJT-X. Please see Digital Modes in the documentation.
+
+Quisk Version 4.2.50  December 2025
+===================================
+This is a quick fix for a bug in 4.2.49 that results in the repeated message
+AttributeError: 'Hardware' object has no attribute 'is_HermesLite2'
+
+Quisk Version 4.2.49  December 2025
+===================================
+This version adds more features for the Anan 10E and other OpenHPSDR radios. Please test.
+
+I added the forward power, SWR, temperature and PA current display to the OpenHPSDR radio. But
+I don't have that radio so I need some help. I think the forward and reverse power connections
+are correct, but it is still necessary to create a table to convert analog input codes to power.
+Go to the Hardware screen and check the "Power meter calibration" setting. You will need to enter
+"New" and create a suitable table. To see the ADC values, choose table "Show ADC".
+
+There is no protocol standard to specify which analog input is used for temperature and PA current.
+And AFAIK the Anan 10E has no such sensors. I am hoping to use the board ID to find the right input.
+The ADC conversion is linear and the two points are specified on the Hardware screen.
+
+I currently assigned the analog inputs as follows:
+AIN1	Forward power
+AIN2	Reverse power
+AIN3	PA current
+AIN5	Temperature
+If you need to see the ADC codes 0-4095 for each input, go to hermes/quisk_hardware.py and
+change DEBUG_SENSORS to one.
+
+Quisk Version 4.2.48  November 2025
+===================================
+This is a quisk fix for a bug in the new OpenHPSDR radios. It fixes use_rx_udp that was reset to zero.
+
+Quisk Version 4.2.47  November 2025
+===================================
+To improve the performance of Quisk with the Anan 10-E and other OpenHPSDR radios, I added
+a new type of radio "OpenHPSDR". Use this type for the Anan 10-E and similar radios. It removes
+all the protocol extensions added by the Hermes-Lite2 project.  I removed the configuration
+option "Hermes Lite2 protocol enable". This is now automatic.
+
+I added buttons for antennas 0, 1, 2 and 3 for OpenHPSDR radios that support more antennas.
+I added controls for the OpenHPSDR preamplifier and attenuator.
+
+I do not have any Apache Labs radios, so I must depend on my users to report problems and solutions.
+
+Quisk Version 4.2.46  October 2025
+==================================
+I fixed a bug in Hamlib rig 2 which happens with the new Pure Signal code. The Hamlib "f" command
+now always returns the main receiver frequency, not one of the added receiver frequencies. This is
+consistent with the Flex ZZ commands.
+
+Quisk Version 4.2.45  October 2025
+==================================
+The new FreeDV including RADE mode is now a built-in mode of Quisk. Just press "FDV" to talk FreeDV.
+In brief, install FreeDV-GUI from the web site. Then configure the usual Quisk digital input and
+output that you use for digital modes. In FreeDV-GUI use the digital input and output. For the
+speakers and microphone use the same ones as Quisk. Don't forget to configure your call sign in
+FreeDV so it works with FreeDV Reporter. For detailed instructions see http://james.ahlstrom.name/rade.html.
+
+The Quisk digital output device is now always active; a DGT mode is not required.
+
 Quisk Version 4.2.44  September 2025
 ====================================
 Quisk now has Pure Signal for the Hermes Lite2. This is baseband predistortion to reduce IMD products.

+# Quisk Software Defined Radio
 
-This is Quisk, a Software Defined Radio (SDR).
-You supply radio hardware such as Hermes Lite2 or SoftRock to convert
-the antenna voltage to I/Q samples.
-Then send the samples to a computer running Quisk.
-The Quisk software will read the I/Q data, tune it, filter it,
-demodulate it, and send the audio to headphones or speakers.
-Quisk has a microphone input and a key input so it can operate as a
-complete transceiver.
+Quisk is a software defined radio transceiver that runs on a PC or on a single board computer such as a Raspberry Pi.
+It is written in Python and C.
+It works with various kinds of radio hardware such as SoftRock, Hermes Lite 2,
+the SDR-IQ by RfSpace, and with network UDP samples.
+Quisk is easily extensible by writing your own hardware file in Python.
 
-The web page for this project is  [https://groups.io/g/n2adr-sdr](https://groups.io/g/n2adr-sdr).
+I wrote Quisk back in 2008, and I have been maintaining it ever since.
+For questions and support, please visit the group https://groups.io/g/n2adr-sdr.
 
-The change log is [here](CHANGELOG.txt).
-
-Installation instructions are [here](http://james.ahlstrom.name/quisk/docs.html#Installation).

+<h3>Digital Modes with the TCI Protocol</h3>
 <p>
+Using the sound devices in a PC to transfer digital sample streams has always caused problems.
+Several new methods are now becoming available. These are the <a href="https://github.com/ExpertSDR3/TCI">TCI protocol</a>
+used by <a href="https://eesdr.com/en/">Expert Electronics</a> for
+their SunSDR hardware
+and <a href="https://www.vita.com/page-1855484">Vita49</a> used by <a href="https://www.flexradio.com">FlexRadio</a>.
+And Hamlib is planning to add digital stream support.
+</p>
+<br>
+<p>
+Quisk can now connect to WSJT-X version 3.0.0 with the TCI protocol.
+On the Quisk Config/radio/Remote screen enter IP address 127.0.0.1 and port 40001.
+Use USB for digital modes. The DGT-* modes are for sound cards.
+In WSJT-X choose the radio "TCI Client RX1", and for audio choose "TCI audio".
+And enter the same IP and port. Everything then just works.
+If your WSJT-X does not have "TCI Client RX1" you need to update to a more recent version.
+This feature is new. To see the TCI conversation, use the "Debug level" on the Config/radio/Options screen.
+</p>
+<br>
+<h3>Digital Modes with Sound Cards</h3>
+<p>
+Digital modes need to receive the audio from the radio to decode it.
+They need to send audio to the radio to transmit.
+These audio streams have traditionally been sent using PC sound cards or
+an artificial sound card known as a Virtual Audio Cable.
 Quisk has a number of modes "DGT-" to receive and transmit digital
-signals. The modes "DGT-U" and "DGT-L" decode the signal as upper
+signals on sound devices. The modes "DGT-U" and "DGT-L" decode the signal as upper
 or lower sideband, and send the stereo audio to the digital sound
 device. The left and right channel are the same.

-Note:  The directory freedvpkg no longer contains source files.  It only contains copies of
-       the codec2 libraries for use by Quisk.  If any other files are present, delete them.
-
-FreeDV and Directory freedvpkg
-==============================
-
-FreeDV is the combination of the codec2 codec and the fdmdv modem.  It provides digital voice
-suitable for HF and VHF transmission.  Quisk has native (built-in) support for
-FreeDV.  Just push the FDV mode and talk.  This freedvpkg directory contains copies of the
-codec2 libraries for use by Quisk.
-
-You can also use the separate FreeDV program available at freedv.org, and the Quisk DGT-U mode
-which attaches to external digital programs. The setup is identical to fldigi and other external
-digital programs.
-
-Quisk will add the FDV button if specified on the Config/radio/Controls tab.
-If there is a problem with the freedv module, the button will be grayed out.
-
-The freedv module requires the codec2 library.  This library is included for Windows and for
-Ubuntu 18.04 LTS 32-bit and 64-bit.  For other systems (such as ARM) you will need to build another
-codec2.  Just try the FDV mode and see if it works.  It should always work on Windows, and may work
-on Linux.  If the FDV button is grayed out, you need a different codec2 than the one included.  Make
-a new codec2 library, and copy it to freedvpkg or to the correct system directory.
-
-2020 mode
-=========
-You can now use 2020 mode with Quisk.  Note however that 2020 mode requires a processor with AVX. 
-Also note a Raspberry PI (model 4B) does not have enough processing power even if neon is used
-and it is overclocked.
-
-There are two parts to this:
-1. build LPCNet
-2. rebuild codec2
-The details are found here: https://github.com/drowe67/codec2#freedv-2020-support-building-with-lpcnet
-
-Both liblpcnetfreedv and libcodec2 are needed.  If you are running under windows, the resultant
-liblpcnetfreedv.dll file needs to be placed in the quisk folder.  Libcodec2 may be placed in the
-quisk freedvpkg folder. Or install the DLL's in the correct system folders.
-
-Search Order
-============
-
-Quisk will search for a valid codec2 library in this order on Windows:
-1.  The system codec2 library installed outside of Quisk by another program.
-2.  freedvpkg/libcodec2.dll.     Not included. You can copy your own codec2 here but a system-wide installation is better.
-3.  freedvpkg/libcodec2_32.dll.  The 32-bit codec2 shipped with Quisk.
-4.  freedvpkg/libcodec2_64.dll.  The 64-bit codec2 shipped with Quisk.
-
-Quisk will search for a valid codec2 library in this order on Linux:
-1.  The system codec2 library installed outside of Quisk by another program.
-2.  freedvpkg/libcodec2.so.     Not included. You can copy your own codec2 here but a system-wide installation is better.
-3.  freedvpkg/libcodec2_32.so.  The 32-bit codec2 shipped with Quisk.
-4.  freedvpkg/libcodec2_64.so.  The 64-bit codec2 shipped with Quisk.
-
-How to Build a New codec2
-=========================
-
-The source for codec2 is available on github.  Or google for other sources or perhaps a pre-built library.
-If you need to compile codec2 from source, first change to a suitable directory (not the Quisk directory)
-and download the source with git:
-
-  git clone https://github.com/drowe67/codec2.git
-
-Then build codec2 using the directions found at https://github.com/drowe67/codec2/blob/master/INSTALL.
-The directions given below are current as of June 2020, but check for changes.
-Then copy the codec2 library to the freedvpkg directory under Quisk.
-
-Build a New codec2 on Linux
-===========================
-Create the codec2 shared library.  This assumes a 64-bit linux. Change the directory
-name from build_linux64 to build_linux32 for 32-bit linux.  Note the "../".
-
-  cd codec2
-  mkdir build_linux64
-  cd build_linux64
-  cmake -DCMAKE_BUILD_TYPE=Release ../
-  make
-  cd src
-  cp libcodec2.so my-quisk-directory/freedvpkg
-
-Build a New 32-bit codec2 on 64-bit Linux
-=========================================
-Make sure package libc6-dev-i386 is installed.
-Create the codec2 shared library.  Note the "../".
-
-  cd codec2
-  mkdir build_linux32
-  cd build_linux32
-  export CFLAGS=-m32
-  cmake -DCMAKE_BUILD_TYPE=Release ../
-  make
-  cd src
-  cp libcodec2.so my-quisk-directory/freedvpkg
-
-Build a New codec2 on Windows
-=============================
-For Windows you need to install MinGW-w64, MSYS2, and g++.  Use the mingw shell.  The Speex libraries
-are not needed by codec2, but are required for the Unit Test modules.  To build the Unit Test modules,
-you need to install Speex and add -DSPEEXDSP_INCLUDE_DIR=../speex/include/speex -DSPEEXDSP_LIBRARY=../speex/bin.
-
-  # Use mingw32.exe 32-bit shell:
-  cd codec2
-  mkdir build_win32
-  cd build_win32
-  cmake -G "MSYS Makefiles" -DCMAKE_BUILD_TYPE=Release -DUNITTEST=OFF  ../
-  make codec2
-  cd src
-  cp libcodec2.dll  my-quisk-directory/freedvpkg
-
-  # Use mingw64.exe 64-bit shell:
-  cd codec2
-  mkdir build_win64
-  cd build_win64
-  cmake -G "MSYS Makefiles" -DCMAKE_BUILD_TYPE=Release -DUNITTEST=OFF -DCMAKE_SYSTEM_PROCESSOR=x86_64 ../
-  make codec2
-  cd src
-  cp libcodec2.dll  my-quisk-directory/freedvpkg
-
-Testing
-=======
-You can just start Quisk and see if the FDV button is not grayed out, and FDV works.  Or you can
-test the import of freedv and look for error messages.
-
-  cd my-quisk-directory
-  python                                # Use the correct Python 2 or 3 in 32 or 64 bit
-    import _quisk
-    _quisk.freedv_get_version()         # This should return 13 or higher for a recent codec2
-

+ *  sha1.c
+ *
+ *  Description:
+ *      This file implements the Secure Hashing Algorithm 1 as
+ *      defined in FIPS PUB 180-1 published April 17, 1995.
+ *
+ *      The SHA-1, produces a 160-bit message digest for a given
+ *      data stream.  It should take about 2**n steps to find a
+ *      message with the same digest as a given message and
+ *      2**(n/2) to find any two messages with the same digest,
+ *      when n is the digest size in bits.  Therefore, this
+ *      algorithm can serve as a means of providing a
+ *      "fingerprint" for a message.
+ *
+ *  Portability Issues:
+ *      SHA-1 is defined in terms of 32-bit "words".  This code
+ *      uses <stdint.h> (included via "sha1.h" to define 32 and 8
+ *      bit unsigned integer types.  If your C compiler does not
+ *      support 32 bit unsigned integers, this code is not
+ *      appropriate.
+ *
+ *  Caveats:
+ *      SHA-1 is designed to work with messages less than 2^64 bits
+ *      long.  Although SHA-1 allows a message digest to be generated
+ *      for messages of any number of bits less than 2^64, this
+ *      implementation only works with messages with a length that is
+ *      a multiple of the size of an 8-bit character.
