[Milsurplus] 1905 Aircraft Radio

[Tom Norris]

Ah hah!

Avitron  models T-17/B and /H are specifically listed by the FCC as  
being
unacceptable for use after 1 Jan 1997 -

http://tinyurl.com/decertifiedradios

I wasn't able to find an online copy of the FAA version of the list.

Sometime between 1990 and 1995, perhaps earlier, the FAA sent
out a notice containing a list of radios that were to be "decertified"
due to change in channel spacing.  I vaguely remember this radio
model being on that list.

One of the reasons for the decertification was that with more
closely spaced channels, a more narrow receiver bandwidth would
be required.  It's very very doubtful I still have a copy of that
FAA notice.

Given the discussion thus far, does the date of the original notice
actually matter?  After all, it was quite a time after 1905... lol
