I just ordered one for dad K8HBI in Florida. You will hear him on 40 meters fists area. Thanks Chuck K9HBI Dan.. I just ordered one for dad K8HBI in Florida.

There is varying degree of discussion why IC151 fails. Regardless since the IC has a high rate of failure in the 746pro. This clearly means the 746pro has design issue that ICOM is not really clear about. I have a 746 original that a got three years now and IC151 has not failed. ICOM claims that it is a static issue, but I find that hard to believe. It is my understanding that 746 pro drive IC 151 with a high voltage which means it is dissipating more heat. So you guess is as good as mine why this part only fails in the 746 Pro. The 746 original all of the 756 line 756, 756 pro, and proII all use the same drive IC.

I think you'll find that they go for a lot more than that, though. Hey, I’d buy one for that price. I think you’ll find that they go for a lot more than that, though.

I couldn't be happier with it. In the two years since I posted this, the furor over IC151 seems to have died down, and it appears that they've either fixed the problem or have been able to reduce the failure rate substantially. In any case, Icom will repair the radio for no charge should this be the cause of failuire. It's not an IC-756PROIII, but I still think it's a great deal.

I'm thinking of getting one, but I need reliability. I use a TS-480SAT right now to calibrate the LP-100s. It's very stable as far as power output goes, and covers 6m. Not a great DX radio though ;-) Who has the lowest price now? At what serial number did ICOM start doing the IC151 fix? Larry N8LP Hi Dan. Just wondering what you think of the ‘746 now.
