I know for a fact that a strikefinder has been made to work and I think at
least one wx500 has been made to work.
However, I think it will take persistence to find every noisy
connection/poor ground.
One LIVP builder that got a wx500 to work also had a full airframe ground
system.   I don't know if this was a factor or not.
IMO a wx500 should work but it's more attention to detail than certain
vendors want to spend.

I have a radar pod I will sell you but I can't be responsible for any
emotional damage you may suffer as a result of heckling on the ramp.
