Align Screen
Test and alignment of RCCR radio is
accomplished using the RCCR
Programmer. All adjustments can be
made via the Align
screen without
disassembly of the radio.
Factory testing characterizes the radio
performance across the specified
frequency range and sets a calibration
factor. This results in consistent
performance, regardless of frequency.
Typically, the radio has been tested near
the middle of the specified operating
frequency band with the resulting values
stored in the radio. The radio was then
tested near or at the highest specified
frequency. The difference between the
resulting values was stored as a “slope”
value, a Δvalue / Δfrequency ratio.
The radio cannot be tuned on a specific frequency or channel using the RCCR Programmer Align
screen. The
Align
screen will display the frequency to be used for tuning.
The “slope” value cannot be changed using the RCCR Programmer for any of the tunable attributes. Instead, the
programmer will allow tuning at the “Alignment Frequency” displayed on the Tune Radio
screen and rely on the
factory “slope” setting to apply the adjusted value appropriately at all other frequencies.
All factory testing is performed at the radio’s nominal operating voltage of +13.8 VDC.
IMPORTANT
The RCCR radio has been fully tested at the factory and should not require adjustment. An authorized RF
service technician must perform test and alignment of an RCCR radio. Do not attempt service of the radio if not
completely familiar with the operation of frequency synthesized radios.
