I got this radio in a trade. Seems to work good but the noise blanker is terrible on the 10m band. I did some investigating and found that the noise blanker unit has been modified. I swapped out the pb1292 board from my 101 Bravo and it works a lot better. A interesting thing to note when the noise blanker isn't even on with the other board it's quieter then the modified board. then when you turn it on it's even more quiet. this modified one does work but it doesn't work as good in either radio. Here are some pictures of the board. a trace has been cut, a jumper has been added and it looks likely at one point cut another teace and two resistors have been added. I don't see where the diode has been changed that people were talking about online. I can't really find any information on this modification on the internet. 73 all Happy holidays.
