Hi, After receiving several nice comments about the TS-940 brochure that I have on my homepage, and for those that might be interested, I have just scanned the instruction manuals for the IF-10B and IF-232C interfaces and put them on my homepage as well. Go to the bottom of the page and click on TS-940 page. 73's Martin de HS0ZED http://www.qsl.net/hs0zed/index.html
