MX800 Transceiver Options
11. Replace the rear connector label with the label supplied.
MX800 Controller Setup:
1. The MX800 RF channels that are required to be simplex should be
programmed as ‘SIMPLEX’ within the channel edits screen of Mxtools
and then downloaded to the MX800.
2. Switches SW2/1 and SW2/2 on the microcontroller board are switched
‘ON’ as per Section 3.6 of the MX800 Manual.
MX800 Testing:
1. Connect a Communications Test Set via the RIB to the MX800.
2. Set the switches on the RIB to Line Audio and E&M.
3. Set the test set to measure Rx line level and ensure that the Receiver is
operating correctly.
4. Set the test set to measure TX modulation level and set the audio
generator output level as per the required line level.
5. PTT the MX800 and measure the TX Power and modulation depth.
Ensure that the coaxial relay operates correctly and that the full RF power
is measured on the test set.
6. Operate the PTT in quick succession and ensure that the coaxial relay
operates in unison with the PTT switch.
7. Replace the MX800 cover.
