- serious bug fixed: Under some circumstances a data sended from computer to keyer could be lost. It caused various undesirable keyer behavior (incorrect PTT configuration, incorrect WK commands, lost data for WK, ...)
- bug fixed: PS2 keyboard/pad sporadically freeze in state in which it didn't respond to key strokes.
- bug fixed: WinKey PinConfig was not always updated on mode change. This caused that incorrect PTT selection (PTT1/PTT2/noPTT) was used.

- Implemented WinKey partial command parser to prevent computer to send WinKey inadequate settings and to have WPM under control.
- PTT selection (PTT1/PTT2/noPTT) was unified for all PTT sources (foot switch, serial PTT, WinKey)
- PTT delay was coupled with WinKey PTT Lead.
- Added possibility to switch mode on num pad (special keys: *0,*1,*2,*3,*4)
- Added possibility to temporarily disable PA/LNA PTT (special key *9)
- bug fixed: WPM control from PS2 keyboard/numpad didn't work in standalone mode.

FSK messages work in both modes; new keyboard mode switching. — summary by updatemystuff.com
Source:
microham.comRelease notes & downloadShow release notes Hide release notes
- When message is played in FSK mode a WinKey commands possibly contained in message (except PTT ON/OFF) are filtered out. It allows playing of "any" message in both CW and FSK modes.
- Added possibility to insert extra FIGURE SHIFT, extra LETTER SHIFT, BLANK and BEL characters to FSK Message. Also PTT ON and PTT OFF commands work in FSK mode.
- New keyboard mode switching: When MK is connected router can force one of CW, FSK or VOICE keyboard mode or can set "manual" to allow user switch modes by CAPS key. When MK is disconnected user can manually switch between CW and FSK modes (VOICE mode cannot be used without router).
- bug fixed: When in CW mode the ALT key (or CTRL in versions older than v2.7) was pressed without entering the new number, keyer stoped respond to keyboard events.
- bug fixed: CK and DK now return correct value of CTS.
- bug fixed: Small bug related to "USB disconnect timer" was fixed.
- Migration to WinAVR 20060125
- Note: Since this version the firmware is updated consistently with "mok" firmware for MK2R.

- Now it is possible to utilize messages in both modes CW and FSK.
- Using of CTRL key was replaced by ALT to prevent interference with some keyboard switches available on the market.
- Some small changes in keyboard evaluation.

Restores PTT2 footswitch output, adds digi keyer support, and improves TUNE function for radio compatibility — summary by updatemystuff.com
Source:
microham.comRelease notes & downloadShow release notes Hide release notes
- PA PTT output can optionaly generate also LNA PTT (with PTT tail)
- PTT2 can be again generated from foot switch like before v1.8 (PTT1/PTT2 from footswitch are always delayed)
- New flag "FSK busy" is generated. This allows to host applications turn PTT off in the right time.
- Function TUNE, started with asterisk on key pad, now generate PTT in advance before CW to overcome problems with some radios.
- Added possibility to temporarily suppress keyboard evaluation. This can be used by router to handle voice message recording/playing from keyer keyboard without mixing with standard function of keyboard.
- support for digi keyer

Fixed FSK channel compatibility with older routers — summary by updatemystuff.com
Source:
microham.comRelease notes & downloadShow release notes Hide release notes
- Because the same firmware is used for whole family of devices (micro KEYER, CW KEYER, ...) there was built in device subtype detection to enable/disable some features.
- bug fixed: Since v2.0 firmware correctly transmits only 5-bits stream on FSK channel. It results in undesirable behavior when router (older than v2.2.2) set FSK channel to non 5-bit mode.

- CTS from radio is passed to computer. When RTS/CTS handshake is set on radio port, keyer respects CTS level and suspend transmition to radio if inactive.
Radio TX buffer extended to 128 bytes.

microham.comRelease notes & downloadShow release notes Hide release notes
- Wide optimalization of code.
- new features:
- Auto numbering in CW mode (ENTER invoke sending of number optionally with report 5NN, number is automatically incremented, can be changed from keyboard)
- Type ahead with buffer of 16 characters (optional in both FSK and CW mode)
- Optional QWERTZ keyboard layout
- Keys ENTER,+,- on numpad have two alternative functions (WPM speed control and auto numbering control) that are toggled by numpad key /. Its old function (side tone control) is obsolete.

PTT2 output removed; serial PTT now supports configurable delay and router v2.0 compatibility. — summary by updatemystuff.com
Source:
microham.comRelease notes & downloadShow release notes Hide release notes
- Added new input flag "any PTT on" that is needed by router v2.0 to display current rx/tx state on audio page.
- PTT2 from WinKey is no longer generated (PTT1 still generated by WinKey)
- PTT2 from foot switch is no longer generated (PTT1 always delayed)
- Serial PTT (both PTT1 and PTT2) can be delayed according to configuration.
- Only one delay constant is used for both PTT1 and PTT2, second is reserved for extension.
-
Fixed side tone-induced data disturbance at high baud rates, added inverted FSK support. — summary by updatemystuff.com
Source:
microham.comRelease notes & downloadShow release notes Hide release notes
- Support for inverted FSK (Dedicated to use with TT-OMNI V or TT-OMNI VI).
- bug fixed: When side tone was turned on, the data from radio to computer was sporadically disturbed, especially on high baud rates like a 57600 bps.
- bug fixed: Data from computer to Winkey are routed without protection against Winkey buffer overflow. Only host application is responsible for this protection. It prevents too late response to message abort.
Use with router v1.13.
