+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.

-# Quisk Software Defined Radio by N2ADR
-**December 27, 2023**
-
-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.
-
-The web page for this project is  [https://groups.io/g/n2adr-sdr](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).
-
-The documentation is [here](http://james.ahlstrom.name/quisk/docs.html).
-
-The help file is [here](http://james.ahlstrom.name/quisk/help.html).

+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.

+<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.
 The bandwidth is set with the filter buttons as

+ *
+ *  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.
