I checked out Irwin Schiff's website:

And it says he'll be back on SW radio for at least one program.

"You can listen here on the internet on Sunday March 14th at 7:00PM
Pacific 8:00 Mountain 9:00 Central 10:00 Eastern time. You may also
listen to the live show on WWCR shortwave radio at 3.210 Mhz."
