I, like many other owners of the IC-211, have one that still operates perfectly. Mine has never failed since the day I bought it new. And it still looks brand new. Dick - W6CCD |

One of my troubleshooting efforts involved fixing the digital readout, which was intermittent. I resorted to completely sucking all of the solder off and resoldering every joint. After that it was very erratic. I finally determined that one CMOS DIP didn't have 5 Vdd on pin 14 like it should have. Further examination revealed that there wasn't even a circuit trace to pin 14. Vcc went to pin 13 and apparently Icom used a solder bridge from 13 to 14 to power the chip. When I cleaned off the solder I broke the connection. A wire jumper fixed that but the Mickey Mouse synthesizer module was hopelessly unreliable, especially while mobile in motion. |

A wire jumper fixed that but the Mickey Mouse synthesizer module was hopelessly unreliable, especially while mobile in motion. The IC-211 wasn't really suitable as a mobile, even though Icom did provide a mount for it. That's why they came out with the IC-245/SSB. You need to remember that the IC-211 was the first radio of that type ever produced. You can't compare the ham radio technology of the 70's with what is available today. For its time, the IC-211 was an amazing radio. As was the IC-701 which I also have in pristine condition. Dick - W6CCD |

I found that there were a few rivets used for "through hole" connection to connect traces on one side to the other near the synthesizer. I soldered those and the synthesizer worked better. Mi 211 sets on the shelf with a broken switch :-( Bill k7NOM |
