If you could find one of those older tunable handheld weather radios, it would probably go up to 164Mhz. (VHF weather channels are around 162Mhz)
You'd have to modify it to recieve CW RF pulses.
I gather you have a carrier at 164MHz and it's modulated with 4.807kHz. Can't tell if it's FM or AM. If it's FM and if you don't need much sensitivity, consider modifying one of those horrible auto-scan receivers you get at the Dollar Store. Should be able to get it up to 164 by taking a few turns off the coil.
