Tait Orca 5000 - Radio Specifications; General Specifications; Receiver Performance

June 2003 IPN: M5000-00-105 Radio specifications B - 3
Radio specifications
Tables B-1, B-2 and B-3 show information
common to all the radios. For detailed infor-
mation on each band, refer to the performance
figures outlined in Tables B-4 to B-11.
The performance figures are typical figures,
unless otherwise stated, for equipment operat-
ing at standard room temperature.
The test methods used to obtain these figures
are those described in the European Telecom-
munication Standard ETS 300-086. Where
applicable, the EIA figure is also given.
Details of test methods and the conditions that
apply for type approval testing in all countries
can be obtained from Tait Electronics Ltd.
Important notes for Tables B-4 to B-11
With regard to the typical performance
figures, specifications are subject to change
without notice and shall not form part of any
contract. They are issued for guidance purpos-
es only. For further information please check
with your nearest Tait office or authorised
dealer who can confirm that the radio meets
applicable regulatory requirements.
* Tait Orca products have an intermediate
(universal) IF bandwidth and can be
programmed per channel for 2.5, 4.0 or 5.0
kHz deviation to cover any channel spacing.
See “Universal band versus wideband IF
filtering” on page B-15.
† TOPB600 batteries are recommended for use
with conventional radios (Orca 501x/2x)
only.
