==================================
Improvement on the low-level sound processing
==================================

The low-level sound processing has been improved. The user can preset the sizes of TX and RX FIFO buffers even independently. If you frequently see "Sound lost" in the spectrum scope window, try increasing the sizes of the FIFO buffers.

Click on Option, Setup MMTTY, and Misc tab. You will find the drop down list for presetting the sizes at the top left corner of the window.

* MMTTY now automatically adjusts the buffer size, which was defined in the Setup menu in the previous MMTTY versions.

================================
Full duplex mode
================================

Version 1.62B has an option that simultaneously runs the record and play functions of the soundcard, so that it can make the external loop back possible. This is useful for the satellite communication and the monitor of the FSK operation.
Click Option, Setup MMTTY, and Misc tab. Select Ext.(SAT) in the Sound loopback pane to enable the full duplex mode.
The local echo option in the TX window of the Setup MMTTY has been deleted as it would result in the same effect as the no loop back mode.

The internal linkage of the TX and RX modules for the no loop back, internal loop back, and external loop back modes are as follows:

<Sound loop back off>

TxData ---> Modulator ---> Sound Out -->
|
--> RX window

<Internal loop back (default)>

TxData ---> Modulator ---> Sound Out -->
|
--> Demodulator -> RX window

<External loop back (for satellite)>

TxData ---> Modulator ---> Sound Out ---->

-- Sound In <--
|
--> Demodulator -> RX window

===================================
TX offset
===================================

Some soundcards inadvertently have different sampling frequencies in the record (RX) and play (TX) operations. With MMTTY version 1.62A, the user can calibrate the sampling frequency for TX. The parameter to be set in the TX offset is the same as that of MMSSTV. To obtain the precise value of the parameter, you have to use MMSSTV. In the case of RTTY, however, the TX offset is not necessarily very accurate contrary to SSTV. So the simple adjustment procedure shown below should give enough accuracy for RTTY.

1) Adjust the RX sampling frequency.
2) Click on Option, Setup MMTTY, and Misc tab. Select Ext.(SAT) in the loop back.
3) Connect the output and input of the soundcard, or select "loop-back" or "Stereo/monaural mixer" in the mixer program of the volume control.
4) Adjust the TXOffset so that the twin peaks in the spectrum scope are on the line marker.

According to my experiences, recent soundcards tend to come into one of the following three categories.

RX TX TX offset
~11025 ~11025 0
~11025 ~11100 75.00
~11100 ~11025 -75.00

Therefore, if you find some discrepancy in the spectrum scope, try putting 75.00 or -75.00 in the TXOffset.

In RTTY, offset frequency 75Hz with respect to base frequency 11025Hz results in 5 to 15Hz frequency discrepancy. The baud rate discrepancy is about 6800ppm (0.68%). RTTY has substantial amount of margin for the discrepancies, so I do not think they are problematic in real QSOs.

================================================
RX log setting moved from the setup menu to the File menu
================================================
To save the system resources in the remote mode, the settings of the RX log have been moved from the setup menu to the File menu. Click on File and select Options of received-log.

==================
EXTFSK port
==================
EXTFSK is used for the USB-FSK interface made by JA7UDE Oba. To use the EXTFSK port, select EXTFSK from the PTT port drop-down list in MMTTY Setup window. EXTFSK.DLL must exist in the same folder where MMTTY is installed. For more information, refer to the following web site.

- Added the Radio Command to the PTT control.  (Tnx to KB2EOQ, JA1WSK and MMTTY-Group) 
- Added repeat function to macro commands 
- Improved output timing of FSK As for older version, there was a bug, and the FSK signal output by Txd was 1 stop bit. Revised to 1.5 stop bits. In the Sound+Txd option, new method to take the same period of both. 

- Added 2nd notch frequency.  Two notch filters when you check  "Two notches" into ON with a part setting Notch of the setup window. In this case of course CPU load becomes heavy. 

- Added one line of macro buttons.  ON/OFF of the macro buttons of an indication menu, you could turn macro button indication of OFF in the older version, but I added the feature to display the macro buttons under the Control Panel.  It may be easier to use the large spectrum and Waterfall. 

- Revised a bug with import text file.  
- Revised a bug with YYYY format.  Conversion of a date with QSO window did not work properly. Revised one point when you selected the YYYY format.  In addition, it can change the output of the date by "%D" macro with the date format. 

[V1.6 2000-12-18] 

- Added the keyboard word-wrap function (thanks to JH1BIH). In the TX window, it reserves the right margin using a space key.  It can be turned ON/OFF in the option menu.  The default is ON. 

- Added two options in the remote mode (thanks to K4CY and MMTTY group) 
-h option allows the user to specify the Windows handle at the startup. 
-n option makes the MMTTY sends the received characters without converting into Baudot 
(raw character mode).

- Added %M and %t keywords to the Macro (thanks to MMTTY group) 
- %M - the contest number portion in MyRST 
- %t - UTC time in 1234 format 

- Added "Commands" button to the Macro definition window (thanks to MMTTY group).  When "Commands" button in the Macro definition window is pushed, all the available keywords are listed and are ready for selection.  Some keywords have different meanings in Macro groups 1 and 2.  Since the Command button displays different keywords according to the situations, I hope it alleviates the confusion. 

- Made the color of the transmitted characters customizable (thanks to MMTTY group).  
The user can define the color of the transmitted characters that are echoed in the TX window.

- Added the import filter for ADIF.  The log data in the ADIF format can be imported to the MMTTY logging facility.  Added the option for FSK-TXD to accommodate USB-COM port (thanks to MMTTY group).  Some USB-COM adapters did not work in the FSK mode. To solve the problem, four options have been added to the FSK-TXD mode.  Go along with [Option], [Setup MMTTY], [Misc], select "Sound+TXD" or "TxD," and push the USB port button to select one of the following options. 
A) Normal 
B) Polling - Transmit characters without using Windows transmission events. 
C) Limiting speed - Set limit to the transmission speed in order to prevent the buffer from being filled with DIDDLE. 
D) Polling and limiting speed - Transmit characters without using Windows transmission events.  Set limit to the transmission speed in order to prevent the buffer from being filled with DIDDLE. Use Normal for the legacy COM port.  If you have a trouble in the USB-COM adapter, try the other three options.  If you see an error message "Cannot open COMx," you would not be able to use the COM port for FSK.  The COM port probably does not support the 5-bit 45-bps mode.

- Added shortcut definitions, OnQSO, OffQSO, and Capture (thanks to JA1WSK and MMTTY group).  The user had to use the mouse to capture the call sign and start/end a QSO. The user can do these operations using short-cut keys.  To activate this function, the user must assign the short-cut keys to OnQSO, OffQSO, and Capture by using [Assign ShortCut Keys] in the Edit option. Capture automatically captures the call sign, which MMTTY guesses it is, in the received text. OnQSO gets MMTTY in the starting QSO state.  If the call sign has not been captured, it executes Capture at the same time. Even if the QSO has started, the automatic Macro sends the sentence for starting QSO. OffQSO gets MMTTY in the ending QSO state. Even if the QSO has already ended, the automatic Macro again sends the sentence that was sent at the previous QSO. 

- Added the style option to the font.  Bold and Italic can be applied to the font. 
- Changed the JCC/JCG text from Japanese to English in the English mode (thanks to MMTTY group).  
- In the English mode, the JCC/JCG are displayed not in Japanese but in the English alphabet. 

- Added notch filter marker in the FFT window (thanks to MMTTY group)In the FFT window, markers are displayed at the center frequency of the notch filters. 

- Added VFO polling function to the Radio Command (thanks to JA1WSK and MMTTY group).  MMTTY logging facility can retrieve the VFO frequency through the Radio Command.  When "VFO polling" is selected in the Radio Command pane, MMTTY reads the frequency of the radio and automatically updates the band information of the logging.  Currently, MMTTY supports only several transceivers that have the Radio Command, but will support others as their command is revealed.  The frequency is logged as follows: Added option to select mono, left, right sound card channel on receive 
NONE freq = VFO 
LSB freq = VFO - MarkFreq 
USB freq = VFO + MarkFreq
