The cable that connects to the EL display is famous for causing problems. I do know the radios can suffer from poor solder joints.
#ICOM CI V FTDI SCHEMATIC DRIVER#
Also had plenty of bad caps in the front mounted display board but mostly to do with the EL display driver section. I can't say I've ever had any capacitor related issues in the logic section ever but I have had issues in the DC-DC convertor board and bad caps in other sections. I wish you the very best of success with this and please do keep us informed with your progress.Ĭlick to expand.Yes, sorry about that as I did go back later and saw where you or someone had mentioned checking at least some of the diodes or jumpers. If I still had my old CT-17, I would send it to you at no charge just so that you could try it, but it's no longer in my possession.
The computer to which the radio is connected has an actual RS-232 jack, so the only thing special about the hook-up was the need to use a 25-pin to 9-pin RS-232 adapter. My current IC-R8500 works well with HRD but the IC-R8500 has an actual RS-232 port so I don't use the radio's Remote (CI-V) jack, which it also has. This is why the CT-17 is referred to as a "Level Converter" by Icom, although it also allows the attachment of up to four radios at once. Note that an RS-232 interface is usually +/- 12 volts DC (direct current), although it can be as high as +/- 25 volts, whereas the Icom CI-V interface runs at TTL (Transistor-Transistor Logic) levels of 0 volts DC to +5 volts DC. The 20-546 is just $23.99 compared to the Icom CT-17 (currently $144.95 at Universal Radio, for example). Abr5 (Jerry), if Tim (mitbr) says that he has an IC-R7000 working with Ham Radio Deluxe (HRD) and a Radio Shack 20-546 USB-PC Scanner Programming Cable, then I would say to give that a try.
