After using an amplifier with manual tuning (Alpin 200) for a long time and also using a manual antenna tuner (Palstar AT2K), recording the required values (tune, load, inductance) and then find the correct piece of paper 😉 was too uncomfortable for me.
So I decided to write a small tool that displays the required values, frequency dependent.
For frequency detection, I have implemented the interface to OmniRig and an interface to TCI (EESDR).
For TCI I have also implemented the “tune”-function. Just click the button, and your Thetis (or SunSDR2) starts tuning! 

All values are stored in a CSV file (tuner.csv). This file is always in the directory from which the program was started. If the file does not exist, it is created automatically at program start.

Since version 1.03 the tool supports two devices per frequency!!

Download 1.33

Release notes see below.

Installation notice:

If you use OmniRig, and OmniRig is running with administration-rights, you have to start TunerReminder also with administration-rights, otherwise you will not be able to connect to OmniRig.

The software is 100% free of charge, no trialperiod or whatsoever. TunerReminder runs on Windows 10/11.
If you like it, a donation will be much appreciated!

Have fun with it!

Release Notes:

1.33

• complete new error handler for omnirig

• synched “on top” with settings and added also to menu

• changed msgbox for adding/changing/deleting of tuner values into an infopanel (to minimize mouse-clicks)

• Update-Info-Window now auto closes after 7s

1.32

• complete rewrite of startup code, allows now to change settings without application restart

• tweaked TCI-Reconnecting

• activity “LED” for UDP output

1.31

• xml-tag “match” now boolean

1.30

• added darkmode for window title

• re-written xml for udp output

1.29

• added process checker for running instances

• added udp output in XML format (see also https://community.apache-labs.com/viewtopic.php?f=9&t=5129)

UDP-Output in a nutshell:
You can activate UDP-Output (data-format XML) via Settings. This will send all data from TunerReminder to a specific UDP-Port.
With a third-party app (like Thetis) you can receive this data and represent it.

1.28

• fixed min/max width & height on forms

• fixed flashing tune button, if tune fails (ie. Thetis not powered on)

• fixed font on vfo b

• fixed “label25” showing up, when not connected

• fixed hide on click in about-box

1.27

• small bug-fixes

• (re) added labeling for device 2 and 3
  Notice for Device 2 and 3:
  Since TunerReminder sorts the entries found by frequency,naming devices 2 and 3 may not make sense in some situations.

1.26

• added option for debug log into settings:
  A debug log will be created in the directory where TunerReminder is started. If something is not working: open settings, check “create debug log” and restart. After the problem has occured, exit TunerReminder and send me the debug log with an error description.

1.25

• fixed a bug where TunerReminder crashes on “Tune”

1.24

• fixed/optimized TCI connect/reconnect

1.23

• fixed display issue on inductance values

• fixed position of update-info window

1.22

• fixed threading issue while connecting/reconnecting to TCI

1.21

• added option in settings to find always closest match (= ignore the +/- 20 kHz span on lookup in your value-table)

1.20

• changed the default install directory to “c:\users\<yourusername>\documents”, because previous setting has some issues on upgrading/uninstalling (if you encounter a problem on setup: please goto control panel – installed programs and uninstall existing TunerReminder first)

• fixed a bug, where TunerReminder could crash on fresh installs

1.19

• all settings are now stored in an ini-file (inside the program-dir) … existing settings from registry will be migrated on 1st program start
  (for migrating your existing tuner-values: copy tuner.csv into the install-dir) 

• TunerReminder comes now with an installer which installs it into %UserProfile%\TunerReminder (ie. c:\users\hamradio\TunerReminder)

• program can now run multiple instances. copy the TunerReminder.exe in a directory of your choice. Each instance has its own settings and tuner-value table (update & uninstall works only for the orginal install-dir)

• values for induction can now be set to “text” (via settings)

1.18

• fixed labeling for device3

1.17

• added option for 3rd device via settings

1.16

• added update checker on program start

1.15

• added option in settings to change label of device

1.14

• added option in settings to change label of “Tune”, “Load” and “Ind.”

1.13

• Bugfix Inductance

1.12

• Extended the range of load and tune to 9999

• Added 2 decimal places to inductance

1.11

• TCI optimization

1.10

• complete redesign (now with VFO A and VFO B)

• TX visualization (on both VFOs)

• click on “SPLIT” activates/deactivates split-mode

• TCI: now supporting “Receiver 1” and “Receiver 2” (via setttings)

• TCI: cosmetic fix on Tune-Button

1.07

• added “always on top” for the entry-window

• added a setting “use VFO-Freq instead of TXFreq”. In some cases getTXFrequency does not work. With this option the frequency will be read from VFO-A/VFO-B

1.05

• corrected typo in main-window-title

1.04

• added “always on top” setting for the main-window

• added warning, if TunerReminder is using Omnirig and not running with admin privileges

• added “bring to top-left corner” to tray-icon-menu (if application-window is outside screen boundaries)

1.03

• Added 2nd device / frequency

• Complete redesign of the filter-engine

• Small bug-fixes

1.02

• Initial Release
