Teletron ← TE-704
Short-wave receiver
- this page is a stub
TE-712 was a professional solid-state short-wave double-conversion
communications receiver, developed around 1977 by
Heinrich Pfitzner GmbH
in Bergen Enkheim (near Frankfurt am Main, Germany)
and marketed under the brandname Teletron [3].
It was the successor to the TE-704.
|
It is suitable for the reception of radio signals between 10 kHz and 30 MHz
in 1 Hz steps, in A1, A2, A3, F1, F4, USB, LSB.
It has a 1st IF frequency of 75 MHz and a 2nd IF of 30 kHz
[2]. 1
The TE-712 was intended for civil and military applications, and was also used
for radio monitoring purposes and intelligence gathering in the 10 kHz
- 30 MHz frequency range. The device is housed in a 4U 19" rackmountable
enclosure that was available in two colour variants: grey and beige.
It weighs approx. 20 kg. At the time of its introduction in 1977,
it had a price tage of DM 50,000 (approx. 25,000 Euro) [2].

At the time, these were common IF frequencies in professional receivers
from Pfitzner
and Telefunken.
|
- TE-712 B
This is the standard model that was used by the German and French services.
Frequencies can be stored in the internal memory and the device can be
remote controlled.
According to [3] there was a variant of this model that had an overload
indicator, but no internal memory. It is believed that this variant was used
by the German Weather Service.
- TE-712 S
This version has a reduced functionality. Compared to the TE-712B, it has
only 6 filters, no notch and spur filters, no Automatic Frequency Control (AFC)
and no diversity mode. Furthermore, it does not offer the F1 and F4 modes.
|
- Colour
It is known that there were at least two colour variants of the TE-712.
For the German army (Bundeswehr) a grey front panel was used, printed with
the word BUND and the NSN number 5820-12-185-7004. It is possible that they
grey variant was also supplied to other armies and countries. In addition,
there was a civil variant with a beige front panel.
- Enclosure
When used as a table top device (i.e. not rackmounted), the device could be
housed in a purpose made metal enclosure, similar to the one used with the
TG-44G telegraphy demodulator.
In case of the grey variant, the enclosure was dark grey (hammer paint),
whilst the beige variant was usually housed in a beige or brown enclosure.
