I tried remote mounting the IRF510 to the side of the case I had my rig
in and managed to blow up 3 before giving up on the idea. I think I was
getting rf into the leads I used (about 25mm long) I then mounted a
IRF510 on the bottom of the board so I could attach it to the case below
the circuit board. I dont have a heat sink as such just the aluminium
case the radio is in. I currently run the final at 19v and only use SSB,
but I have run mine with as much as 28V on the final with this
configuration without blowing the IRF510. Make sure the tag of the IRF
510 is insulated from the case as it will blow if it shorts to earth.
