Subject: ICOM IC-701 extended freq. mod.

From: Carl Hodder  Subject: Computer control of ICOM 701 via accessory connecter.



The August 1984 issue of QST (page 19) has an article on computer

controlling the ICOM IC-701 HF transceiver by it's rear panel

accessory connector. Although the article describes controlling

the radio by a dedicated Three-Chip Microcomputer which can be

built for $20 (the cost of the three chips) if you already have

some common parts. This project can easily be adapted to control

the radio by an IBM PC. Please refer to the QST article for more

information. The same interface and control commands also work

for the IC-211 and IC-245 transceivers.

I also heard of a mod using pin #11 (transverter) but can't recall

the details. If you know of any other mods for this radio please

email me at sba3020


All mods are at your own risk, so please be careful.



Hope that helps, Carl (VO1XY).
