I have the following receivers coming in soon that I want to investigate any
possible mods that can be done. I already know what Kiwa can do so those
don't need to be mentioned.

AOR AR3030
Drake SW-2
Palstar R30C
Lowe HF-150

I will as usual be investigating upgrading the IF filters but any other
known mods would be interesting to hear about

thanks to all with the good stuff to contribute.
