SV-COM-760, SV-COM-T25 and SV-COM-T83 Installation and Configuration
SkyView System Installation Guide – Revision AK (draft) 16-21
SETUP MENU > ENABLE 8.33 KHZ (SV-COM-X83) > NO.
This setting can be changed back to 8.33 kHz at any time.
Post Installation Checks
• On Ground
• Do all SV-COM-PANEL buttons and knobs function normally?
• Verify dim commands from SkyView display dim the backlighting of the SV-COM-
PANEL.
• Does the (optional) FLIP/FLOP pushbutton swap the STBY and COM frequencies?
• Does pushing the PTT switch cause the SV-COM-X25/X83 to transmit (only) when
pushed?
Do not transmit without an antenna connected. Doing so will damage your
Transceiver Module.
• (Optional, if two transceiver modules installed) Does the PTT Select Switch cause
only the selected radio to transmit when PTT switch is pushed?
• Temporarily install a VSWR meter between the transceiver module and the
antenna. Using brief test transmissions, is the VSWR 2.5:1 or below? The
maximum acceptable VSWR for transceiver module is 2.5:1.
• When transmitting on transceiver module is there any interference to other
aircraft systems?
• Power off the SkyView display(s) by pushing and holding Button #1 on the
display. The SV-COM-XXX should continue to operate normally, with the
exception that auto-population of the button frequencies will not occur, and a
NO SV error message will appear approx. 3 seconds after SV is not operating.
• In Flight
• Does the SV-COM-XXX receive other aircraft and ground transmissions at
reasonable ranges?
• Does the SV-COM-XXX receive other aircraft and ground transmissions equally
well at the low end, middle, and high end of the Aviation band?
• Is received audio clear at most volume levels on the SV-COM-XXX? (Distortion at
high volume levels is normal.)
• Are transmissions from the SV-COM-XXX heard by others at reasonable ranges?
(Keep in mind that the power output of the SV-COM-XXX is 6 watts.)
• Are transmissions from the SV-COM-XXX clear (when received by others)?
Continued Airworthiness and Maintenance
• Periodically inspect the COM antenna for wear and weather-tight seal to the fuselage.
Water intrusion could corrode the antenna connection.
• As with all wiring, periodically inspect the COM antenna’s coaxial cable for wear; repair
or replace if significant wear is found.
• Periodic function checks as required by your aviation authority.
