Somebody on this mailing list (I forgot who) has a web page
that says the IR receiver module (38kHz, side-look) from
Digikey (www.digikey.com), part no. 160-1153-ND, is pretty much
identical to the part listed in the HB Tech. Ref.
I bought one, but I haven't tried it yet. According to the
instructions I saw, it's supposed to be wired up like so:
-------------

I haven't even reviewed the HB schematics yet to determine
whether the capacitor and the resistor are already part of the
HB circuit. Anyway, I hope this helps.
