Try taking the covers off. I had a stryker 955 that had a very similar issue right out of the box. It would only misbehave with the bottom cover installed....I'm curious.

That's usually an indication of insufficient shielding within the unit itself. Even though the cover is grounded, it can still reflect output signal, back into the input stages. The problematic area can often be located by slowly sliding the cover over the equipment and noting where the problem starts. Shielding over or around that area can fix the problem. It did on oscillations in the driver stage of the FT-857 on 6 meters.

Nothin' more fun than pinning down a fault that only appears with the cover in place.

I would also check the ground screws around the edge of the circuit board. They tend to loosen and cause issues with stability.

That was it. I used a cover from a smaller radio to find the general area. The small shielding boxes on the board were not soldered to gnd. After doing that and bonding them all together it was good.

Have had no issues with my N2.
Been working flawlessly for yrs.

Yeah I’ve had my n2 about 6/7 years now and never s problem. I talked around the world hooked up mobile in my otr truck. Australia, Indonesia, South American, best radio I ever had. I now have a icon 718 I’m gonna hook up.
