The Omni D series B (which it sounds like is what you have), can only be
modified for 24 mhz and 10 mhz.  18 mhz is not possible.  There was a kit
containing several coils that did the mod for these two bands.  This kit
sold for $25 back in the 80's.  I recently saw one for sale on this
reflector just a few weeks ago.   This kit adds 10 mhz transmit and 24 mhz
transmit and receive to the AUX position of the band switch.  I do not
recommend doing this mod without the kit because of the complexity in making
the specialized coils and transformers.

If you have an Omni C, then all you need is crystals.  The Omni C has 10,
18, and 24 mhz right on the band switch.
