I always wondered why the jst-245 has a double image of a CW signal when not using the 500Hz filter. That means that it looks that you hear the usb and lsb from a reveived CW signal. Does this occur on every rig? Any idea's to fix this? Rgds, WIlko Wilko J. Hollemans PA3BWK member of VERON, ARRL, VRZA Remember: without CW it's just CB !
