Hi,
For EMFcamp, I am preparing two Akai GX-77 reel-to-reel 'full
autoreverse' decks
to play music in a fully analog, electromagnetic way:

They are using 1/4" reel-to-reel tape pioneered by AEG and BASF, pre
WWII.
These days magnetic tape in this broadcast format is only commercially
available
from Ampex, USA, via sites like thomann.de, large dutch retailers don't
have it.
correction: Thomann.de only sells new tape from ATR Magnetics and RTM
(recording the masters),
Ampex went mostly defunct in 2014 according to wikipedia
https://en.wikipedia.org/wiki/Ampex
Old tape is usable too, as long the tape's
oxide-to-tape binder quality
was ok.
The GX-77 decks will be adapted to include remote control and remote
pitch control and rudimentary cueing features so they can be used along
with vinyl records.
Timecode extraction and -slaving from the other stereo head (it is a
dual 2-track
autoreverse machine) should be possible as well, although it goes a bit
against
the 'all analog' dogma, and would mostly suitable to match film or
video - for cueing
the latency of vinyl, capstanless direct-drive of the actual reels
would be best.
For this the dual reel motor drive circuit needs to be redesigned,
worst case replaced.
The music itself should ideally being taped from FM radio, in the
highest quality possible.
What stations worth listening to in .nl (could be local) should I check
out
and what genre's should I bring to EMF ?
