Would appreciate any help here. I have the icom IC-2730D and would like to expand the TX range. it currently has a range of upto 440Mhz that is standard. I have also looked up forums mentioning to remove the D307 and D315 diode, which should solve my problem . Unfortunately the unit I have doesn't have these diods similar to the 2730 and 2730A and am currently lost. Any help right now would be appreciated.
