SV-COM-X83 Transceiver and Panel Installation and Configuration
SkyView HDX System Installation Manual - Revision E 15-11
particular radio, aircraft, antennas, and terrain (buildings), it may be necessary to have
some distance between you and the helper (being right next to each other will not be a
valid test). With the helper listening on your (not heavily in use) test frequency, adjust MIC
GAIN slowly up or down, pausing between transmissions.
For example, set MIC GAIN to 55, speak “Test1, Test2, Test3, Test4, Test5”, then pause
a minute or so for other transmissions to be heard. The helper should reply whether your
transmission was weaker, or stronger than the other transmissions. If the helper indicated
your transmission was stronger than the other transmissions, adjust MIC GAIN lower, and
do another set of transmissions. When the helper hears your audio to be about the same
volume as the other transmissions, MIC GAIN is set correctly.
If other people report that your transmissions fade off at the end or can't be heard at all,
you may need increase MIC GAIN. If your transmissions are reported to sound "hollow",
"robotic" or if they have a lot of background noise, you may need to decrease MIC GAIN.
Also note these issues can only be heard on real transmissions by third parties.
The audio you hear in your headset (Sidetone) when you transmit is
unaffected by the MIC GAIN setting. As explained above, the best method to
set MIC GAIN correctly is to work with a helper who is listening to your
transmissions on a different radio.
15.3.1.3 Displayed COM (Top Bar)
The status of one (1) COM radio can be displayed on the top bar. The radio that is
selected here is also the radio that you can send airports and frequencies to via SkyView’s
Map Menu APT>COM and TUNE COM buttons. See the SkyView Pilot’s User Guide for
additional details.
• Go to SETUP MENU > SYSTEM SETUP > DISPLAYED COM and select which COM
radio status to display on the Top Bar (or NONE). (To display status of a non-Dynon
Avionics radio, a serial port connection must be installed FROM the radio TO the
SkyView display(s).
15.4 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-X83 to transmit (only) when
pushed?
