[1000mp] MKV RX Relay Problem

[Piotr Gutkiewicz]

Hello Thomas and others!

I have the similar observations with my FT-1000MP Mark-V. I always
disconnect the antenna when not operating the radio. But "sticky relays"
problem has gone three years ago when I moved radio grounding wire mounting
point from default "GND Terminal Post" to antenna "B" ground (outer)
connector. I have one multiband antenna only and have no power amplifier so
when not operating I disconnect both antenna and grounding wire from the
radio and I connect antenna to this grounding wire. I wonder where your
grounding wire goes? Maybe you have your antenna already grounded on the
roof or your antenna switch is grounded?

73! Peter, SP5CFD
