Development History. (Latest to Earliest)
8-27-26
Releasd 0.971. Changed text box for TEST button to display module number and fault number which caused TEST to stop, i.e., A1A5-3, the same number displayed on the RT1446. Added FAULT LED above VFO A to display Red when TEST fails......
7-5-19
Release 0.962c. Fixed problem with Sidetone. Radio turns off Sidetone on the first selection of AME mode after powering up. Program now restores initial Sidetone setting when changing from AME to other modes. Fixed problem with PTT Enable button to restore user's setting when exiting Out-of-band condition. Fixed interlocking between Swap, Tune On, Xmt On, and PTT buttons.
8-24-18
Release 0.962b. Fixed freeze-up (Program not responding...) in Scan Bands. Allow changing scan limits while scanning.
8-8-18
Release 0.962a. Fixed logic that caused XMT, TUNE, PTT, and PTT En buttons to flicker. Noticed that if an RF350 Antenna Coupler is used during Split operation, the radio may enter a tune cycle each time PTT is clicked. To avoid this:
Enter the transmit frequency in VFO A.
Enter the receive frequency in VFO B.
Select TX A.
Click PTT. The Antenna Coupler should tune on the transmit frequency.
Click Swap and select TX B.
Click PTT. The Antenna Coupler should not tune.
11-21-17
Release 0.962. Fixed problems that caused radio to crash in v0.961. Allows Split only when both frequencies are in USB, LSB, or AME. "Out of Band" limit now depends on the transmit VFO to allow transmitting so VFO A may be used to listen out of band. Note: If you want to transmit outside the Amateur Radio bands, you may add a file named "Permissions.txt" to the "RT1446 Files" folder. Added "Test" button to initiate radio self-test. Label under Test button will show "FAULT" if Self-Test fails or if fault occurs during operation. Program caption date: 11-21-17 : 1600.
10-01-17
Release 0.961 is being withdrawn. It was discovered that PTT command did not work correctly in Split mode when VFO A Mode is different from VFO B Mode. Also discovered that radio needs some time after changing frequency before start of transmit. New release 0.961a will partially fix the problem but Split Modes has been abandoned for now.
09-04-17
Release 0.961. Replaced MEM/VFO button with option buttons CHAN and VFO. Replaced Split button with option buttons TXA and TXB. Reduced delay time to start transmit in Split. Changed tuning rate of VFO A. Program caption date: 09-04-17 : 1100. Updated Help file. NOTE: Microsoft updates to Windows 10 may remove WinHelp which supports 32 bit help files. I had to re-run the script described above to re-install WinHelp
05-01-17
Release 0.960. Activated VFO B Mode for Split and Swap. Swap VFO A and Mode with VFO B and Mode. Save VFOB Mode, SplitOn/SplitOff, Ext Knob Step Size at exit and restore at startup. Program caption date: 04-30-17 : 2134.
05-01-17
Fix to 0.950f. Fixes error caused by selecting CW mode. Last modification to v0.950. Program caption date: 5-01-17 : 1453
03-30-17
Release 0.950f. Minor fix to avoid runtime error caused by older ini file format. Program caption date: 3-30-17 : 1208
03-29-17
Release 0.950e. Activated External Knob controls which were invisible. Added "OFF" value to Step Size to disable knob input. Added save and restore of VFO B value in ini file RT1446ini.txt. Delete this file in Users\Public\RT1446 Files folder before first launch of program. Tested program on Windows 7 64Bit.
Fixed bugs in 01-22-17 release:
Mode, AGC, Audio Source, and Digital drop-down menus would not select new values.
01-22-17
Release 0.950d. Added keyboard input to change VFO A. "i" increases, "d" decreases. Might work with "Griffin Knob" but not tested.
Fixed bugs in 12-17-16 release:
Band Select looked for text files in Program Files folder.
Frequency change fails for repeated short mouse clicks.
Frequency for 60M channel 3 was wrong causing Out Of Band
New release should show date: 1-22-17:2231
12-18-16
OOPS! Previous release had some problems with PTT button going into endless transmit if RS232 DSR not set up for external PTT. Sorry! New release should show date: 12-17-16:2319
12-13-16
Version 0.950c dated 12-10-6 released. This revision eliminates several message boxes including "Sync Timeout" and "Mode Error". Program recovers by getting status of radio and re-establishing Sync. Eliminated confusion caused when radio initiates transmit to tune antenna or amplifier.
12-7-16
Version 0.950b dated 12-6-16 released. This revision provides for disabling the DSR External PTT. Program will recall its screen position from the last use.

Help for Windows Help. Microsoft Visual Basic programs are compiled to 16 bit code. When they are run on 32bit or 64bit Windows systems, the compiled help files are not compatible. Microsoft provided a program Winhlp32.exe for Windows 7 to connect the 16bit help files to programs .Unfortunately, Winhlp32 was not updated to work with Windows 8 and Windows 10. It's really the same program but the installer won't work on Windows 8 or 10. I found a program on the web which allows changing the installer so it works with all Windows versions. I have wrapped the necessary files up in a ZIP file for downloading.
Download Komeil-cab.zip . Follow the instructions in the included PDF file Making Windows 32 bit Help files work in Windows 10.pdf .
11-29-16
Version 0.950a dated 11-27-16 released. Added Memory Channel selection and programming. Added second VFO dial for split and swap operation.
11-3-16
Version 0.931b dated 10-30-16 is available. Fixed problems with exit when no com port was available. Added method to interface external Push to Talk via Com Port.
9-29-15
Version 0.931a dated 9-29-15 is available. Fixed error in previous version which caused program to enter endless loop when response from radio was missing linefeed. Usually happened during transmit.7-3-15
Information about connecting the Logging Program Com Port to the RT1446 Program CAT Port is detailed in the file:
6-29-15
Version 0.931 dated 5-29-15 is available. Fixed to save current audio source when switching to digital mode and restore when returning to phone.
5-24-15
Version 0.931a is available. Still somewhat Beta. This version adds a dropdown menu to choose Digital Modes OFF, PSK, FSK, RTTY. Audio Setup Menu includes choice of audio channels to use for digital signal. Choosing a digital mode causes the Audio Source to cycle to the desired source: MIC, Audio2, or Patch. The CAT Mode data sent to the logger will indicate SSB, PSK, FSK, or RTTY.

Some notes on CAT ports and Help files... The ports for CAT should be established in Device Manager before the program is started. USB RS232 ports need to be connected first and device drivers loaded. Virtual ports such as VSPE can be set up by running the virtual port manager at Windows Startup before the logging program and RT1446 are started. If the programs are started by shortcuts in the Startup Folder, the VSPE shortcut should be run first. This can be accomplished by making the name of the shortcut start with a "0" since Windows sorts the files alphabetically.
RT1446.Hlp is compiled as a 32 Bit help file. Windows 7, 64Bit, will need an update installed to read the help file. The Windows popup when you click RT1446 Help will give a link to the download page.
5-15-2015
Meter Functions directly selectable
RF Gain Control simplified
BFO Control simplified
CAT emulation to provide Frequency and Mode to logging programs. Set your logging program to use Kenwood or TS-450 protocol. Use two Com ports to connect the programs. Set the ports for compatible parameters. At NB6GC, we use virtual COM ports provided by Virtual Serial Port Emulator, (VSPE), from Eterlogic.com .

RT1446Probe_V040 (8-18-11)
This is a program to investigate the responses of the RT1446 to commands. It can be used to test for proper or undocumented responses. Download RT1446Probe_v040.zip . The program doesn't need to be installed if you have the required Visual Basic support files. Just extract the files to a folder. Visual Basic source files are included.
