The following technical documents are available to help you understand how you can build your own transmitter:

Encoder revision 4.0
Firmware for the revision 4.0 Encoder.
There are two sets for firmware for the rev 4.0 Encoder:
1.) The adapter version for use in the rev 3.0 encoder with an upgrade adapter installed.
2.) The rev 4.0 PC board version for use in the new encoder PC board.
Adapter versions: Rev 4.0 encoder PCB versions: The rev 4.0 encoder PIC contains two programs, the boot loader and the encoder application. The bootloader is a simple program that allows the PC application to download updated encoder versions using the serial port.
There is only one bootloader version and it works on both the rev 4.0 encoder PC board and the upgrade adapter.
Every adapter I ship and every PC board with a PIC installed also has the bootloader installed. You should only need this file if you are installing and programming your own PIC. You will need a programmer to install this file into a PIC.

July 20, 2008 update:

The latest update to the Encoder requires you to update both the PC interface application and the encoder PIC software. You can download both of these application here. Make sure you install and the PC application first and read the ICP help information to learn how to setup this version. I am no longer building multiple versions of the encoder software for different hardware options. The encoder software can be configured with the PC application for your hardware configuration.

Version 2.0f hex file, encoder firmware

Version 2.4 MicroStar PC interface application

Encoder firmware version 2.0f updates include:

	1.) change snap buttons to allow sticks to still function, A,E,R only
	2.) Fixed bug in the throttle stick timer enable
	3.) Fixed bug in the stick position switch function
	4.) Added stick speed control to select aircraft and percentage
	5.) Add message to indicate you are in slave mode
	6.) Beep when the trims are set to zero
	7.) Added servo slew rate control to channel 5 and 8
	8.) Allow the user to select the RF deck ref osc frequency
	9.) Allow adjustment of the framing rate and frame time defect

Encoder revision 3.0 (obsolete, file are here for reference only no more updates will occur)

RF Deck
The RF Deck can be built two ways. In standalone mode a PIC mircrocontroller is used to configure the PLL when power is applied. This PIC will read the frequency selection switches and program the PLL for the selected channel. The RF Deck can also use the Encoder to configure the PLL. In the standalone mode you will need to program the PIC, this download will give you the firmware you need, in Intel HEX format. ICP
The PIC processor used in the Encoder (revision 3.0 only) can be programmed using my In Circuit Programmer hardware and my ICP.EXE DOS program or you can use the ICP feature in the PC application available above (revision 3.0 only). These downloads contains the documentation and the ICP.EXE program. Using this system you can program the PIC without removing it from the Encoder. You will, however, need a eraser to remove the old PIC programming before you can reprogram the PIC.
If you are using the revision 4.0 Encoder you need no special hardware to download new version of the software, just the PC application.
