What the purchaser will find out, if they implement the 11 meter modification, is that they no longer will be able to just select channel 1-40. They will have to know the frequency of each channel they operate on. Every time he/she changes channel, he/she will have to convert a channel number to a frequency. Maybe the memories could be programmed, but it will still complicate the operation. It's a waste to use such a capable radio on a small sliver of frequencies.If the purchaser doesn't have any real experience modifying radios, there is a good chance the radio will never work again. And, wait till he/she finds out how much DC power the radio requires. His Radio Shack 3 amp supply isn't going to cut it.
