Custom EAS Receiver
(was TFT EAS-930A, now EAS-1)

Fit & Finish
All the panel machining is done, now it's time to mount the nomenclature decals,
and check the controls for fit ... or possible mechanical interference.
All controls mounted, including the meters, pots, rotary selector and toggle mode switches, the three BCD decade switches, and the indicator LEDs.
Note that the BCDs are tuned up or down (frequency) by pushing little buttons above and below the numerals.
The green LEDs indicate which receiver module is functioning and the yellow LEDs trigger when AGC level is above the noise floor (usable signal).

Right: Closeup of the BCD (frequency) switches,
(behind the little doors) that required a
screwdriver to adjust.
Misc Photos
Various shots of the panel to document the details.
Final chassis assembly.
Here is the unit, finished
and working.

It's only been burned-in
for about 6 hours now, so
I'll let it sit and play for
awhile before doing
some of the final tweeks.

Thus far, I'm really
impressed with the

After dark, I'll check out
the AM DX ability again.
Last night I tuned around
for about 2 hours and
really had a lot of fun, but
the true test will be to
repeat the testing on
many consecutive nights
so that we experience all
that nature can do to the
atmosphere and

It's kind of nice to have
the calibrated S-meter to
keep signal records from
one night to the next and
compare to some of my
other radios.

The VU meter is set to
monitor the drive level of
the audio that I send to a
hi-fi system with good
quality speakers. Zero
dB = 0.707V into 600
Ohms, but it will drive
loads down to 150 Ohms

Amazingly, some of the
AM broadcasters still
strive to deliver good
quality audio to their
customers ... that is,
without over compression
or peak limiting in an
effort to increase their
coverage audience. Too
bad. That's a common
practice among many
broadcasters, but be
assured, there are still
many that adhere to the
precepts of quality and
operational integrity.

Tonight, my regulars will
be the usual Midwesters;
WLW-700, WLS-890,
KDKA-1020 ... all from
the heartland into
Southern New England.
There are many others
from out there, and the
South, too ... testing is
hard work, but someone
has got to do it ... fun, fun.
Finished and Working
If you are a tinkerer and happen to find a TFT (brand) ESE-930 Emergency Broadcast Monitor on one of the used equipment lists, well,
then you just may want it - a good, solid platform to play with. The 930's architecture is modification-friendly and almost any rework
customization is possible and easily done. This was a fun project - with very rewarding results.

Thanks for looking and good signals to you.
