You're correct.  The IC-W32A might be available from other vendors, and if
HRO's web site no longer has the W32A listed then their stores have probably
sold their remaining stock of those radios.

As for the IC-91A/AD that Icom is advertising as the replacement for the W32A,
it is not a full-duplex radio.  In fact, it will take some manual
effort to use the new
HT with satellites, since its memories won't accept frequencies in
different bands
like many Kenwood and Yaesu dual-band HTs.  I played with the IC-91A at
Dayton, and asked specifically about the radio's capabilities related to FM
satellite work.  It sounded like it would be as useful as my IC-T7H -
it can work,
but with swapping the TX and RX frequencies manually to work the passes,
and not full-duplex.  :-(  Seems like Icom replaced the cross-band full-duplex
capability of the W32A with D-Star.
