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].
As 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
[1]. 1
The TE-712 was intended as a military intercept receiver, and was used
for radio monitoring purposes and intelligence gathering in the 10 kHz
- 30 MHz frequency range. The unit is housed in a 19" rackmount case
and weights 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.

of this receiver, which shows great similarity with that
of the KE-30 Stay-Behind short-wave receiver.
