how to preserve old RL01 pack data?

I have some old DEC RL01 packs with PDP-11 diagnostic utilities - these are DEC originals: AX-E380L-MC DLDP+DIAG#1 + DECX A1 SYSTEM A AX-E441L-MC CZZLBLO DLDP+DIAG #2 + CPUTST + DECX B1 SYS B They won't last forever, and I don't have any spare media to back them up to, so I'd like to archive this software onto my PC (for posterity - or perhaps to make available to other hobbyists for use in the emulator, though I'm not sure whether the Mentec license would cover this - it does say "and associated utilities" however). The question is, how can I get a copy of a pack as a binary image onto the PC ? (to load in simh for example ?) I have a working serial port, and I can run kermit OK on RT-11. However, even if RT-11 will read the pack in DL1: (and I'm not even sure of that), how can I persuade kermit to take a copy of DL1: as an image ? I haven't found a way of doing this. Simply doing "get DL1:" doesn't seem to work. Is there any kermit-like software out there that has a PC client and can do a disk image transfer ? Thanks in advance, F
