Version history (last entry first)

If you use Yaesu rotators you need one of these to achieve the full connectivity:
Yaesu SDX 800, 1000, 2800: https://www.ebay.com/itm/384721667452
Yaesu DXA 800, 1000, 2800: https://www.ebay.com/itm/133801762652

Thanks to Vlada OK1NVV for tests with his FT-991.

• HR stores an exact frequency (Hz) to a log (on condition it was connected to the TCVR).
• Fixed behavior when an external monitor is used together with the main display ("extend" mode).

• When an Icom TCVR is connected for the first time HamRacer offers to modify setup of TCVR. The purpose is that it matches options selected in HamRacer. This is done through CI-V commands. Tested with IC-9700.
• Minor fixes and enhacements.

• Full support for dual-port devices (transceivers). A single USB cable setup is now supported (all CW keying, PTT control and SSB modulation through one cable).
• Improvements in KST chat.
• CW keying and PTT control over the CI-V protocol commands (much better than DTR/RTS). Available for Icoms only at the moment.
• Improvements in the messages editing dialog.
• The wizard connecting a new device was vastly improved.
• Automated check for 6 hours block, or two block with at least 2 hours space, when IARU 6 HOURS category is selected. This happens when exporting to EDI.

The advanced features were developed and tested with IC-9700. It can be assumed they will work seamlessly also with IC-7300 and IC-7610.
Note: due to the new features it was necessary to change the format of the hardware IDs in Options. You will have to connect all the serial devices again.

• Fixed CI-V communication (frequency readout) for 1286 MHz band.
• Modified the frequency change on changing CQ / S&P. If the user doesn't click on a frequency marker (DX Spot) in the analog scale then the frequency remains the same.
• Pressing CapsLock can control PTT not only for Spider Keyer.
• Tested the "all-thru-usb" setup with IC-9700

• Fixed behavior of the "compass" when the segment crosses the 360/0 degrees. This happens when you enter the big square that is to north of your locator.
• Implemented the rotator control. It follows the Yaesu spefication described in Yaesu_GS-232B_Manual.pdf.
  The intention is to make use of the original control box Yaesu SDX 1000 enhanced by the optional board that provides the serial communication (available on eBay).

• Retro search improved. When the retro search is on a small floating window will pop up. With a single button click you can find previous/next suspicious QSO to deal with.
  
• ON4KST chat improved. When you type a message (both to a certain station or to all) and press [Enter] the text is sent and the main window is re-focused. Alternatively, when you click the button Send the ON4KST window retains the focus and you can type a message for another station.
  
• A new feature - Profiles. It is convenient for contesting teams where more OPs take turns at the same running HamRacer instance.
  If you require different options than the others (keys schema: native/simple, paddles normal/swapped, different keyer messages, ...) simply create your own profile and make all the necessary changes in Options. When it is your turn simply select your Profile.

• Added the possibility to control PTT by CAT commands over the USB/COM connection to the TCVR. This can simplify harness in some setups. It is currrently available for all protocols except Icom CI-V.
• Detecting an ad-hoc serial device that was just plugged into the USB socket is now much faster.

• HamRacer doesn't prevent the Windows system from shutting down any longer. Instead, it terminates gracefully.
• When the Windows system goes suspended HamRacer disconnects from DX Cluster and ON4KST chat. On the system resume it reconnects in case it was connected before.

• Minor ergonomy improvements
• Fix in the resolution PX/Callsign => Country

• The compass showing the desired direction yields more accurate and reliable behavior when the direction is exactly to North or South.
• Now it counts 1 point (1 km) when QSO happens in the same locator. This matches the recommendations from IARU.
• Improvement when too many stations are on the tabs in the ON4KST window. The tabs are spilt to more lines when necessary.
• RBN window shows DX spots (different continent) in bold characters. Also, it is possible to list all DX spots first in the list.
• Speed improvements (assignment of a country to PX or CALL). This makes difference mainly if you have many hundreds of QSOs in the log.

• Import/Export of ADIF fixed/enhanced
• Copy/paste from/to a log enhanced (you can copy QSOs from HamRacer to e.g Notepad or MS Excel, modify, and then copy back).

• Working with ON4KST chat was improved. Thanks for the hints to Martin, OK1MCW
• Device detection improved (more devices attached at a time). Thanks for the hint to Jindra, OK4RM.

• When the log is loaded from the automatic storage (HamRacer was just started) or when it was loaded from a file (*.log) and then modified, then when a user does something that could lead to a data loss (starts a new contest, deletes all QSOs, ...) then the previous QSOs are stored to a hidden temporary file in the background. The file is kept for 10 days, then automatically deleted. This highly improves a chance to restore data when a less experienced user fiddles with HamRacer.
• Minor ergonomy improvements.

• Yeasu CAT is now supported to controll your TCVR. Mind that this is the original protocol that Yeasu developed years ago. It will work with TCVRs like FT-817, FT-857, FT-897, FT-847 and similar. Because Yeasu recently changed the protocol, without renaming it and without keeping backward compability, it won't work with the recent TCVRs like FT-991.
  
• Dx spots inserted into the analog scale are painted in red color in case it is a new multiplier for the contest:
  

• The new macro {SAVE} for messages was added. If this macro is used in a message the QSO is stored automatically on the message playback. Applicable for both CW and SSB. The position of the {SAVE} macro in the string doesn't matter (be aware of redudant spaces). The QSO is stored after the playback.
  The {SAVE} macro has no effect if:
  o- the complete properties of QSO are not yet entered (callsign, exchange, ev. locator)
  o- the playback of the message was interrupted (F12, touching the paddles)
• Instead of a local time HamRacer now uses a system time. This fixed the problem that occured during CW WPX SSB (European contesters only). The problem occured because of the time change (ordinary time to summer time, and vice versa) during the contest.

• HamRacer now reconnects all serial devices after the PC was resumed from the suspended mode. It is important for Spider Keyer which forgets the initialization values while being w/o power.
• Minor enhancements and fixes.

This version also offers the new sketch for Spider Keyer: 1.37

New version of Spider Keyer sketch (1.35), what is new:

• If the automatic sending is interrupted by paddles the interrupting dot or dash is not transmitted.
• More accurate manual sending while the speed potentiometer is being rotated.

Spider Keyer version 1.35 and higher won't work correctly with HamRacer versions prior to 1.7.0.0.

HamRacer 1.7.0.0 and higher will work seamlessly with any version of Spider Keyer.

• Enhancements regarding RS(T) handling. Sent RST is fully editable now and received RST is optional (Stew Perry).
• An uknown country (4U1A) can now be easily added to the database.
• The new version of sketch for Spider Keyer 1.30.
  What is new in Spider Keyer 1.30 (1.31):
      o - It is possible to save configuration of the keyer into Spider Keyer EEPROM memory. When Spider Keyer starts it takes the configuration from EEPROM. This is useful when Spider Keyer runs stand-alone (not connected to PC).
      o- A new push-button (PCB ver. 3.0) can send a programmed message (CQ...). A long press does the key-down (tune ATU etc.).

• The ON4KST chat stuff is significantly enhanced. Except the "running" list there is also a list of all the users that are currently logged into ON4KST. Double-clicking an item in either of them will create a separate tab for the callsign. This tab shows the aximuth, locator and distance. It enables to copy the callsign and the locator into the main HamRacer window.
• New option in the contest properties - it enables to specify how to treat DUPEs (HF).
• Fix of the occasional short "freeze" when connected to a DX Cluster.
• Fixes in the way how Band's points are calculated.
• Other minor fixes and enhacements

• For uploading of the sketch into Arduino Nano the two bootloaders are now supported (ATmegaBOOT @ 57600bps, Optiboot @ 115200bps). This way both the genuine Arduinos are supported as well as the older units and the cheap Chinese clones.
• If the word debug is supplied on the command line that starts HamRacer then a special log file File log.txt will be created on your Desktop. Don't expect much useful information in it. However, if you experience any problems the author will be thankful for the file. Delete the word debug if the problem is resolved in order it doesn't slow the things.

• It is possible to swap paddles for left-handed OPs. It is implemented for both WinKeyer and Spider Keyer. Mind that Spider Keyer needs upgrade (by selecting an option from the main menu of HamRacer) for this to work.
• Selection Curtis-A/Curtis-B is now available for WinKeyer as well.

• New option for Exchage to receive: Any string including spaces
  This will enable you to use HamRacer in contests where two or more items are to be logged for the exhange, such as NAQP.
• When you select two or more QSOs in the list the sum of points and the average QSO distance is calculated only for the selected segment (VHF).
• Configuration is automatically saved in background after each change. This yields a better user experience.
• When logged to ON4KST and when some stations talks to you all the chat with this station appears filtered on a separate tab. The tab disappears when the station is QSOed or it can be closed manually.

• It is possible to send a SKED to another workplace (different VHF/UHF/SHF band) in a multi-operator environment.
  In the recipient's analog scale it appears as a new flag such as "432-->OK1ABC".
  
  Double clicking the flag does:
  o- Switches to the Search & Pounce mode (when necessary)
  o- Selects the proper mode (SSB/CW)
  o- Tunes the TCVR to the frequency that was negotiated by the sender
  o- Fills in Callsign and Locator
  o- Moves the cursor to the Exchange field
  o- Rotates ANT to the relevant azimuth (planned for future releases)
  
  For this it is necessary that all PCs with running HamRacers are connected to the same LAN segment.

• Export to EDI (VHF) revised. It now suits better the multi-operator logs.

• Implemented automated system for upgrading of the installation.
• Minor fixes and enhancements

• It is possible to connect to a DX Cluster (telnet protocol) now. When connected, a large analog scale pops up. Flags (DX Spots) are showed in the scale as they arrive from the DX Cluster. Single click on the flag tunes TCVR to the frequency. Double click tunes to the frequency, switches from CQ to Search and Pounce and copies the callsign.
• Options reorganized to be more easy to navigate.

• HamRacer can speak two languages now. The main language (always English) and the 2nd language (your choice). It currently supports Czech as the second language but it can be easily configured to speak any other language, too. The language is selected automatically in dependency of what callsign input.
• It is possible to control PTT with CapsLock key on the keyboard. Convenient for manual CW sending or for SSB with a headset.
• Enhancements in Synergy (e.g. you can prohibit the connected HamRacer to delete or modify QSOs in your log).

• It is cheaper than WinKeyer 3
• The source code is published. Anyone can modify it to meet his needs
• Using the same HW, new features can now be implemented, such as ANT rotator control, switching beverage ANTs, etc
