http://www.73.com/a/0019.shtml offers a "block converter". (among
dozens of other items! It's about 3/4 down the page on the left-hand
side, stock #AE047) It's a broadband frequency converter that will
convert a US channel 3 RF signal up to US channel 37.

I called these bozos to inquire about buying one of these. You get an
answering machine but not the courtesy of a call back. The items have
also disappeared from their web site inventory.

Any other sources?
