Newer Post Older Post Home.Open the bottom lid of the radio. The end result was awesome One of the pics here is the filter as modeled in software, the violet curve is before mods, the white curve is after mods. This moves the knee of the filter from 5. I checked the manuals and board layouts against each other, and while the filter units in the standard and Pro II are physically a little different, the circuit was the same. He came up with a few capacitor changes to alter the upper end of the filter response to fix the problem in the Pro II.
He had access to some filter design software, and modeled the 80m filter to see where the problem was. Another ham I was talking to on the internet had the IC Pro II and modified his for 60m coverage as I did, and had the same problem with low output power. Here's the info for the first phase of the modification I found that the band matrix is setup to use the 80m low pass filter up to 6. First, the transmitter has to be opened up for general coverage operation.
