Poor RX

sensitivity or no RX audio

Inject a standard FM test signal into the antenna port. Use CPS to ensure that attenuator feature is disabled. Use a spectrum analyzer and high-impedance RF probe to measure the IF signal on side 2.

3 kHz FM deviation,

1 kHz rate, -47 dBm

Frequency OK?	No	Check
UHF: 73.35 MHz		RXLO
UHF: 73.35 MHz		RXLO

Yes

IF

level about Yes 1 -38 dBm?

No

Measure RF

input level

at TP02

RF level			No		Inspect coaxial		Visual			No
about			No		antenna connector		inspection			No
about					antenna connector		inspection
-47 dBm?					and cable assembly		OK?
	Yes							Yes



Measure RF levels at TP02							Remove cable
and TP13 ,							assembly, measure
compute SW_FL loss							insertion loss

SW_FL		No	Check	Loss			No
loss < 2 dB?			SW_FL	< 0.2 db?
	Yes				Yes
	Yes				Yes

2				Bad antenna connector.
2				Replace chassis
				Replace chassis
				(connector is not
				serviceable)

Replace bad part
