MX800 Transceiver Options
3.2 T02 Programmable CTCSS encoder/decoder
3.2.1 Description
Provision is made in the MX800 to fit a CTCSS encoder/decoder. The
decoder is non-predictive and any valid CTCSS tone can be decoded. Any
standard TX CTCSS tone may be associated with the programmed decode
tone through the Channel Edit screen in MXTOOLS. Multiple CTCSS tones
are programmable for any channel providing "Community Repeater"
functionality.
This option may be fitted at order placement or retro fitted subsequently.
3.2.2 Installation
Components Required:
1. PART# C051 FX805 or MX805AP IC. Qty-1
Method:
1. Remove the cover to the MX800 radio.
2. Locate the socket for IC25 and install the MX805AP IC into this socket
ensuring correct IC pin orientation.
MX800 Controller Setup:
1. The RF channels that are required to be CTCSS controlled should be
programmed with the required CTCSS Subtone in the TX and/or RX
channel fields.
MX800 Testing:
1. The Option T02 will require a ‘Peak Deviation and Modulation Balance
Alignment’ as per Section 5 of the Technical manual. This alignment is
to be performed without the CTCSS frequencies programmed into the
alignment channel, as the subtone levels will give a false indication of the
peak deviation levels.
