Amateur Radio Transceiver

[gbowne1]

I am designing and building a radio transmitter that works in the bands from 1,800 KHz to 30MHz.

It is based on a 10 year old design that uses a 3 chip computer using the 80C31 and a 27C64. The EPROM is supposed to have 2,008 lines of assembly code.

I am redesigning the circut so that it is not so modular. The original design was designed to be housed in a small chassis. I now have two rackmount chassis that I wish to use with the project, one 12" high and the other 6" high. They both go about 22" front to back. The design is spaced over about 7 different PC boards. I would like to either slim it down to about 3 boards or design a planar system using ISA type 8 or 16 bit bus cards.

I am intending on updating to 2006 technology.

The original design used a 2 row, 16 character per row. LCD display that is backlit. I was planning on doubling that to 4 x 32.

I need to know what I could change the controller to in the update.

I can post text files of component lists from the original design or parts of the original text.
