SV-COM-X83 Transceiver and Panel Installation and Configuration
15-12 SkyView HDX System Installation Manual - Revision E
• (Optional, if two (2) SV-COM-X83s 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 SV-COM-X83 and the antenna.
Using brief test transmissions, is the VSWR 3:1 or below? A good installation
should have VSWR of 2:1 or even 1:1. The maximum acceptable VSWR for
SV-COM-X83 is 3:1.
• When transmitting on SV-COM-X83, 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-X83 should continue to operate normally, with the
exception that auto-population of the buttons frequencies will not occur, and a
NO SV error message will appear approx. three (3) seconds after SV is not
operating.
In Flight
• Does the SV-COM-X83 receive other aircraft and ground transmissions at
reasonable ranges?
• Does the SV-COM-X83 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-X83? (Distortion
at high volume levels is normal.)
• Are transmissions from the SV-COM-X83 heard by others at reasonable
ranges? (Keep in mind that the power output of the SV-COM-X83 is 6 watts.)
• Are transmissions from the SV-COM-X83 clear (when received by others)?
