RECOMMENDED PERIODIC CHECKS

Perform XMTR local oscillator frequency verification (Para. 5.18) and XMTR output check
(Para. 5.19) 1 year after initial setting and at 5-year intervals thereafter to correct possible
drift caused by aging.

RADIO TROUBLESHOOTING

The digital radio system is equipped with alarm circuitry and automatic switching (in hot-
standby, frequency diversity, and space diversity configurations) to provide protection
against loss of traffic. This automatic switching, coupled with adaptive equalization of mul-
tipath distortion, provides protection against equipment outage and propagation varia-
tions. Because of the finite life of electronic equipment, failures occur.

5.9.1

Troubleshooting USI Alarms

First alert for an alarm is normally the USI Status Alarm Screen. See Figure 5

3 through

12 for detailed alarm information and troubleshooting guidelines. After isolating

the fault to the most probable cause, replace module or repair as directed.

5.9.2

Troubleshooting RCVR Lockup Problems

The radio is operational when the RCVR is locked onto the associated farend XMTR fre-
quency. Normally lockup occurs within minutes after power is applied. Successful lockup is
indicated by not having the channel alarm (Chan Alm) lit on the RCVR front panel.

5.9.2.1

Slow Lockup At Initial Turnup

Slow lockup at initial turnup is defined as lockup occurring five minutes or more after pow-
erup. If the radio is non-standby/no space diversity (one RCVR in A side), replace the
RCVR. If radio is non-standby space diversity or hot-standby (two RCVRs, A and B sides)
problem is probably the XMTR at the farend of the hop. The most common cause of slow
lockup is incorrect carrier null. First try switching XMTRs. If this clears the problem, per-
form carrier null (Para. 5.20) and XMTR/P A output level calibration procedure (Para. 5.21)
on the off-line XMTR. If the problem is not cleared, replace the XMTR.

5.9.2.2

Slow Lockup During Normal Operation

Slow lockup after a bad fade or other temporary interruption is defined as lockup occurring
less than a second after RSL is restored. Troubleshooting this type of slow lockup requires
knowing what the RSL is. Check RSL using the procedure in Appendix G on attached CD.

If the RSL is at least 4 to 5 dB above RCV threshold, the two most probable causes are carrier
leakage and the RCVR local oscillator. Perform carrier null test (Para. 5.20) on the farend
XMTR. If slow lockup continues, remove and replace the RCVR crystal oscillator subboard.

If the RSL is below or 1 to 3 dB above RCVR threshold, wait until RSL improves to at least
4 to 5 dB above RCVR threshold before starting troubleshooting.
