SECTION 6
ALIGNMENT OF THE RADIO LINK
6.1 INTRODUCTION
This chapter details the alignment procedure for the PTRL-NV
transmitter and the RXRL-NV receiver.
6.2 FREQUENCY ALIGNMENT
The operating frequency of the complete radio link (TX + RX) is set
using a frequency meter to measure the frequency output by the transmitter
and the frequency after the second conversion of the receiver.
It is recommended to align both units (TX and RX) at the same time and
with the same frequency meter, preferably one of high precision
(eg. ±0.2 ppm).
A difference grater than 2 KHz between the transmitter’s center frequency
and that of the receiver (measured at the intermediate frequency of 10.7
MHz) will result in degradation of audio quality and stereo separation.
To perform this alignment, carry out the following procedure (SETUP A1
and A2):
1)
Connect the transmitter as shown in SETUP A1 (Fig.11).
SETUP A1
