Frequency Hopping (Option - Export Permit Required)
The Barrett 2050 employs a unique frequency hopping system that uses an
external ESU (Encryption Synchronisation Unit).
Note:- The external ESU must be connected and providing valid data for the
frequency hopping system to operate.
Selecting the Hop Band
Select the channel used for normal/clear transmissions based on the normal
procedures used when using an HF system, this channel frequency and mode is
used by the Barrett 2050 to determine the hop band. .
Note:- The reference frequency in NOT a centre frequency for the hop band. It
simply determines which of the preset hop bands are selected.
Entering the Security Code
For hopping PIN code entry refer to the “General” section of the Protected Menu, in
the subsection “Hopping PIN”, select the security PIN code based on the
information below.
Security Codes and Bandwidths
Security codes 00000000 to 19999999 are used for hopping +/- 2 kHz
Security codes 20000000 to 49999999 are used for hopping +/- 16 kHz
Security codes 50000000 to 99999999 are used for hopping +/- 128 kHz
Note:- Hopping up to +/- 2 kHz is useful for narrow band antennas such as when
using antenna tuners in manpack operation.
Note:- Hopping up to +/- 128 kHz can be used with wideband antennas such as
base station broadband antennas.
Note:- Once entered the security code for security reasons can never be retrieved
or viewed.
