I have a FT1000MP and my Orion coupled with just a Y connecter in the keying
line to my Henry 3KD for over three years and have had no problems using
either radio.

It could be that the 1N4148 will have a volt or more of drop depending how much current it takes to key the amplifier and that diode drop may keep it from working right. -- 73, Jerry, K0CQ, All content copyright Dr. Gerald N.
