Latest release of PSR-500/600 "CPU F1.5" Firmware has been released.
CPU Production Firmware Version 1.5 release notes:
- This is the user loadable version of the Factory 1.5 CPU firmware.
Will display as "uP Appl Ver:U1.5" after loading and is identical to
the factory "F1.5" load.
- Please use with DSP version 1.2 or higher, otherwise some features
may not operate properly
New features:
* Per FCC approval, changed 700 MHz frequency tunable range to:
764000000 MHz - 805996875 MHz
(all on 3.125 kHz steps)
* Changed 700 MHz ranges in Public Safety Search and Sweeper to:
764000000 MHz - 766996875 MHz
769000000 MHz - 775996875 MHz
794000000 MHz - 796996875 MHz
799000000 MHz - 805996875 MHz
(all on 3.125 kHz steps)
* Added "connect tone" display to M36 analyze mode, alternating
with other data (QQ% SID:xxxx Syy).
* Added "OmniLink" 6-char site name to M36 Analyze mode alternating
with other data (QQ% SID:xxxx Syy).
* Added "RadioIDAlert" item to FUNC+GLOB menu. If set, then we'll
show the private TGRP's alert when:
a. showing a group call.
b. showing the private TGRP's tag on line for for the radio ID.
c. private TGRP's "LED Color" is non-zero (the default 'off').
d. new menu item enabled.
Fixes / Enhancements:
* Fixed missing 'DG' display for digital trunked VCs (bug that
was introduced in F1.4).
* Fixed P25 CC analyze problem with system ID info (bug that was
introduced in F1.4).
* Added timeout to trunking analysis results in TUNE mode, so
spurious false detects (esp. Mot 3600 low-speed) won't cause
persistent display of trunking data.
* Fixed issue where occasionally, pressing MAN while in SCAN mode
would not go to the last active object.
* Fixed problem when multi-scanning some EDACS systems.
* Swapped Source vs Target Radio IDs in handling of EDACS
"I-Calls" per customer reports.
* Un-swap (version 1.4) source and destination radio IDs when showing a
Private Call Wild Card where the source ID was locked out.
* Fixed search modes possibly skipping a freq while paused, if
zeromatic is turned on. While waiting for unmute delay, we were
checking zeromatic even if paused.
* Added additional qualification to storing polled P25 NAC. We
only store it if:
the new NAC is non-zero, OR
we don't already have a NAC value, OR
the NAC value we already have is zero
Other:
For users that have VHF trunked systems which utilize 5 kHz
centers, the following changes were made:
* Allow 5 kHz steps between 138 MHz and 174 MHz. These are
enabled with a new menu item in FUNC+GLOB.
If not turned on, use the 'normal' steps.
If turned on, 5 kHz steps are used in ALL modes.
CONV objects created in one "mode" will tune based on the
"active mode" - that is, if you create a CONV object 138.005 MHz
with the feature enabled, the radio will tune to 138.000 MHz if
the the feature is not enabled (although 138.005 will be displayed)
* Changed default receive mode for 138 MHz to 144 MHz to AM if the new
"5 kHz" feature is disabled in the FUNC+GLOB menu (default).
* Changed default rx mode for 138 MHz to 144 MHz to FM, if the new
"5 kHz" feature is enabled in the FUNC+GLOB menu.
