I don't know if any of those receivers are narrow band or not.
However, Futaba never did narrow band receivers, only transmitters.
Receivers are too small, and it's cheaper to just replace them.
The golden stickers were only for transmitters, not receivers. (The
FCC doesn't care about receivers, only transmitters.) Receivers often
had a `1991' sticker on them around the time of the switch that did
indicate narrow banding, but I don't think they add them any more.
This link --
suggests that at least some of those receivers are narrow band, but
hardly proves that all are. (And I suspect you've already found this
You could test it -- have somebody transmit on a channel adjacent to
yours while you're transmitting and see if it causes problems for your
receiver. This isn't a perfect test, however, as there are pager
channels in between our R/C channels, and this won't provide a signal
for that channel. Of course, even brand new, narrow band equipment
often can't handle a strong signal on an adjacent (10 kHz away)
If you do just decide to replace it, you don't have to replace it with
another Futaba receiver. Hitec, FMA and Berg all make receivers that
are Futaba compatible and generally have better performance than
things like the R127DF. And they usually cost less.
