[1000mp] Sticking relay problem- Not just a Yaesu problem

[Harry Yingst]

I have found that my Mark-v Field seems a lot more sensitive to RF then
the Icom radios I have run in the past (even at low power levels).

I wound up putting some ferrite on almost every lead in and out of it

I also have the internal tuner shut off and the a/b switch off as well.
