Quisk version 4.2.35

+Quisk Version 4.2.35  June 2024
+===============================
+There is a new item "File play level" on the Config/radio/Sound screen to reduce the volume when playing files.
+Use it to reduce the volume of the CQ message relative to radio sound.
+
+Dan, AI2M, provided a patch to compile in MacOS on Apple Silicon. Thanks Dan!
+
+I am working on better amplitude and phase adjustments when using SoftRock radios. The new corrections
+screen has a spreadsheet to display the VFO and tune offset. And there is a feature to automatically
+measure the corrections when using a signal generator as a source. If you use Quisk with SoftRock or similar
+radios, please let me know what you think.
+
+Quisk Version 4.2.34  May 2024
+==============================
+For the Hermes-Lite2 the inhibit Tx function (CN8) now releases the Spot button.
+
+Quisk displays the band plan below the X-axis as colored bars, and there are eighteen possible colors.
+If you hover the mouse over a bar, Quisk now displays the name of the mode. Recall that there is a dialog
+box so you can set the band plan to what you want.
+ 
+Quisk Version 4.2.33  May 2024
+==============================
+Added the get_level Hamlib command "l STRENGTH". It returns the S-meter reading. I finally found some Hamlib
+documentation, often not an easy task.  The return value of STRENGTH is in dB with zero dB equal to S9.
+There are 6 dB per S-unit. So a STRENGTH of 4 is 4dB over S9, and -6, -12, -18 is S8, S7, S6. I also added
+the corresponding FlexRadio command ZZSM.
+
+Quisk Version 4.2.32  April 2024
+================================
+I found and fixed a bug in the microphone filters that can result in a buffer overrun. You should update Quisk.
+
+Some Linux digital programs can not use the usual Quisk Pulse loopback device and must use an
+Alsa loopback. I added more documentation for Alsa loopbacks, added more information on the Sound
+screen and I changed the default Alsa sample size to 16 bit.
+
+Quisk now responds to the Hermes Lite2 Tx inhibit input by displaying a message and extinguishing the "Tx" light.
+There is a new item "Hermes Lite2 protocol" on the Hardware screen to control this behavior.
+
+Quisk Version 4.2.31  March 2024
+================================
+The "Tune" item was missing from the Midi menus. I fixed it but I didn't test it because I did
+not borrow Ben's Midi controller. Please test it yourself and let me know if it works. The Midi
+speed can be set from the menu too.
+
+Quisk Version 4.2.30  March 2024
+================================
+A new option "Tx-Rx silence msec" on the Timing configuration screen controls how long
+to suppress Rx audio when switching from Tx to Rx. The previous fixed time was 50 msec.
+
+The SSB squelch control now works on CW too. Please test.
+
+Quisk Version 4.2.29  January 2024
+==================================
+This version updates the FreeDV library files and program logic. I added a "Monitor"
+item to the FreeDV menu. It routes the sound to the speakers instead of to the demodulator.
+Turn on both the monitor and FDX to listen to your transmitted FreeDV signals. Please test.
+
+Modes 700x and 1600 are finished. The other modes will be added shortly. If you use any of them
+post here and I will move them to the top of the list.
+
 Quisk Version 4.2.28  December 2023
 ===================================
 This version includes a patch from Jon, AB8WU, to build Quisk on FreeBSD. Thanks Jon!

-<br>
-<br>
-This will install the Python files and all other files except for the C source. This is the easiest method
-if you do not want to work in C.
-To run Quisk, use this command from a terminal:
-<br>
-<br>
-python3 -m quisk
-<br>
-<br>
-You can create a panel launcher on your desktop with the command to run Quisk.
-<br>
-<br>
-If the installation of Quisk fails, you can force re-installation:
-<br>
-<br>
 </p>
-<pre>
+<br>
-sudo -H python3 -m pip uninstall quisk
-sudo -H python3 -m pip install  --no-cache-dir  --force-reinstall  quisk

+Installation to the system Python is no longer allowed, and you may get the message "error: externally-managed-environment".
+If you used pip to install Quisk you can continue to upgrade with "sudo python3 -m pip install --upgrade quisk"
+until you get this error message. But it is best to uninstall the pip Quisk. If you installed with pipx, uninstall that too.
+</p>
 <br>
-You can also install an older version of Quisk. You may need to do that if the most recent version fails for some reason. Use:

+<h3 id="LSI">Linux Source Installation</h3>
+<p>
+On Linux, Quisk is installed from github, and it is contained in a "quisk" directory. First you need to decide where to put the
+quisk directory. Anywhere will do, but it is best to use a directory where you have write permission so
+you don't need to use "sudo". The examples below assume you used your home directory indicated by "~". Just replace "~"
+by your desired location.
+</p>
 <br>
+<p>
+To install a fresh copy of Quisk, change to your desired directory, clone the github site, change to the quisk directory and run "make".
+Then run the python program quisk.py.
+</p>
 <br>
+<pre>
+cd ~
+git clone https://github.com/jimahlstrom/quisk
+cd quisk
+make
+python3 quisk.py
+</pre>
+<br>
+<p>
+If "make" fails, you probably have missing packages or missing "-dev" packages. Try to figure out what is missing from the error messages.
+You only clone github for the initial installation. To update Quisk, use pull:
+</p>
+<br>
+<pre>
+cd ~/quisk
+git pull
+</pre>
+<br>
+<p>
+You run Quisk by running the file quisk.py with python3. For example, "python3 /home/jim/quisk/quisk.py".
+You can create a desktop icon to do that, but the method depends on your version of Linux.
+<b>Never run Quisk with root privelege by using sudo. Fix the permission problem instead.</b>
 To get started you must tell Quisk what kind of radio hardware you have. Press the Config button and select Radios.
 Then set your sound devices for that radio; the device for the radio speakers, the microphone and so forth. All configuration
 is (mostly) from the Config button. Ignore old directions and don't bother with a config file.
-<br>
+To uninstall Quisk, just delete the quisk directory.
-<br>
-To edit the Quisk Python files you need to know where they are. To find out, import quisk and print it:
-<br>
-<br>
-</p>
-<pre>
-jim@IntelNUC:~$ python3
-Python 3.6.9 (default, Oct  8 2020, 12:12:24)

-<h3>Linux Pip Upgrade</h3>
-<p>
-To upgrade to a newer version of Quisk, use pip:
-<br>
-<br>
-sudo python3 -m pip install --upgrade quisk
-<br>
-<br>
-</p>
-<h3>Linux Uninstall Quisk</h3>
-<p>
-sudo python3 -m pip uninstall quisk
 </p>
 <br>
-<br>
-<h3>Linux Source Installation</h3>
-<p>
-The previous method using pip is simple, but will not install the C source files. If you want those proceed as follows.
-Go to <a href="https://pypi.org/project/quisk/">https://pypi.org/project/quisk</a> and under "Navigation"
-select "Download files". Download the quisk-x-x-xx.tar.gz file. This is the source file. The ".whl" files are for Windows.
-Change directory to where the file was downloaded, probably "Downloads", and uncompress and untar it.
-<br><br>
-cd  ~/Downloads
-<br>
-tar zxf quisk-x.x.xx.tar.gz
-<br><br>
-Change directories to the Quisk directory:
-<br><br>
-cd quisk-x.x.xx
-<br><br>
-Now compile Quisk with the "make" command:
-<br><br>
-make quisk3
-<br><br>
-If "make" fails, you probably have missing packages or missing "-dev" packages. Try to figure out what is missing from the error messages.
-Now you can run quisk with the command:
-<br><br>
-python3 quisk.py
-<br><br>
-At this point you have a choice of where to install Quisk. You could just rename the quisk-x.x.xx directory
-to a more convenient name, like "quisk" in your home directory, and run Quisk from there.
-This is convenient if you want to
-alter the Quisk code. Or you could install Quisk into the Python system.
