Modifications

Icom IC-736 Filter selection Less white noise Headphones AF filter Settable sidetone level ~~Meter back-light bulb replaced with LED~~ Meter made transparent Setting BFO for CW The DDS/VCO bugfix More filters at 455 kHz IF More filters at 9 MHz IF Receiver OUT / Receiver IN	Icom IC-740 Four crystal filters at 455 kHz Three crystal filters at 9 MHz Addtional roofing filter AF Filter (100Hz at 700Hz) Marker unit (like IC-EX241) IC-EX243 Keyer modification Usage of TDA2003 Volatile VOX modifications Internal ventilator External attenuator Settable sidetone level
Icom IC-275A (E) Modification of cooling	Yaesu FT-897D transceiver: Four filters at 455 kHz (yes, it is possible....) A simple modification reducing a white noise above 3 kHz Even more noise suppression - AF filter
Icom IC-730 Pre-amp relay replacement, antenna relay replacement, etc...	Dressler D200 144MHz Power Amplifier Faster R/T switching Mechanical and electrical modifications
RFT EKD300 professional receiver: Faster AGC, reverse BFO, AF filter, replacement of LEDs
