Yaesu FT-817 Portable QRP MF/HF/VHF/UHF Transceiver
Attention newsletter editors: If you are interested in reprinting these things (that's a technical term) in your not-for-profit newsletter, e-mail me first. You must agree to some simple terms before publication.
A note regarding formats: most of the files are available both in standard web browser-compatible HTML format and Adobe Acrobat (.PDF) format. I recommend you first browse the HTML file on-line, and then download the PDF if you want a printed copy. Acrobat PDF files are very well compressed, yet the graphics print out with excellent quality--the schematics are much easier to read from a PDF printout. If you do not have the Adobe Acrobat Reader, follow the link into Adobe's web site. The reader is free.

The FT-817 has many features and few knobs and pushbuttons, so a menu system is used to access most of the radio's functionality. The most important commands are summarized on a single page that you print and carried along with the little radio.
The receive-mode current draw of the rig with various supply voltages is graphed.
The 5W transmit current draw of the rig with various supply voltages is graphed.
This circuit interfaces Yaesu solid state amplifiers (FL-7000, Quadra) to the FT-817, providing automatic band selection as well as T/R control, etc. Outputs are provided for DuneStar/ICE band pass filters, or may be employed for automatic antenna selection. An RS-232 serial interface is also included. [New 2 March 2001]
