Radio static

[fastfred]

Anyone have and input on this problem. When I key the mic it makes a loud static . Very uncomfortable. So far I have checked the settings adjusted the squelch . It started one day when talking to the tower with a Helicopter running near by . I keyed the mic and got blasted with static and helicopter blades. I tried to adjust it out and lost the tower for few minutes. The controller was not happy with me..

What comm? How far are your coax cables from other cables?

FastFred,

If you have a new or different headset, or new or different radio, you might need to adjust the mic gain (first) or the sidetone on the radio itself.

When you speak of picking up helicopter noise in the transmission - that makes me think a look at the mic gain is a good place to start - might be set a little high.

Information on doing this is a bit skimpy in most radio manuals, however the David Clark headsets have some instructions in their headset manuals.

If you don't have a new or different headset or radio - might need to start somewhere else.

IMHO....Radio=Voodoo

It is a Garmin SL 30 and Sl 40. I did just install the dynon ADS B in unit which has coax running to the Antenna. He just ran it next to the existing harness.

I never had any static, maybe because I grounded the panel as instructed from the get-go.

Jim,

I think you might be confusing people with what 'panel' you're talking about. I think you're talking about your Dynon EFIS 'panel' but others are talking about the instrument panel itself i.e. the metal thing with holes drilled in it. It might be useful if you clarified which 'panel' you are referring to.

[jiott]

Yes, I had to ground my Dynon Skyview panel.

[fastfred]

Was your static all the time or just when you press the mic? I will check the grounds though when I get a warm day

Check for good grounds on radio and push to talk switch also.

If the problem manifested after the ADS-B install, I would check anything new from that work. Suggestions such as the routing of new antenna coax (RF bleed over).
