Just what the title says.  I am tired of the tower asking me to repeat, or telling me I am unreadable due to the loud "buzzing" noise in the back ground.  I have checked it out with my brother flying and me listening in on my hand held and the "buzzing" is the cockpit noise of the dang 2 stroke, not an electrical or interference noise.



We are currently running a JHP-520 hand held, Flight com 5DX head sets and have tried sigtronix, flight com and PSE Aerocom II.  I have tried david clark headsets as well and still have the dang 2 stroke scream.  I know alot of guys are using something that works.  I plugged the headset directly into the radio and it was worse.  It seems that the PSE intercom has worked best, but still leaves alot to be desired.



Dave, I noticed in your videos that you dont have the loud 2 stoke scream in the back ground on your transmissions so what set up are you using?



I am wanting to order what ever it takes for my plane so I can fly direct over the tower to my favorite destination and not annoy the tower with crappy transmission's.



Thanks

I'm happy with my Lynx Micro headsets and radio interface -

http://www.lynx-avionics.com/English_Site/E_Site_Index/e_frame_set.html.

They ain't cheap but the noise cancelling electret microphones + built-in

speech processor do the job pretty well, they are designed for use in open

cockpit (UK) ultralights where the 582 is almost a headrest and absolutely

nothing between you and the engine. Or you and the wind. Or you and the

ground! And my KF2 with 582 can *not* be flown without ear protection, the

db level can be disorienting otherwise.



They also have many configurations from single headset noise protection to

multiple headsets fully integrated into your radio system(s). Even helmets.

Len,

I don't know for certain about the handheld you are using, but every damn

handheld I've tried in an airplane has had some problems with many different

things.  I've never used an aviation handheld in the cockpit, but I've tried

a few different amateur radio handhelds, and the biggest problem I've

encountered with them is that the internal mic is NOT disconnected when an

external mic is plugged in resulting two mics in parallel, 1/2 the impedance

needed, and some draw down on mic voltage circuitry.  The internal mics I've

dealt with ARE NOT directional mics, nor are they noise cancelling  They

didn't work worth a flip out of the box. Cutting the connections on the

circuit boards at the internal mic solved most of the problem, and turning

the mic gain pot down also helped.

Are you using the rubber ducky antenna attached to your handheld mounted on 

your dash?  Try an external antenna mounted back in the rear of the plane. 

Way better reception and less noise.

I have tried both ways.  It was actually better using the rubber ducky than the external in terms of the tower hearing me.  I have a feeling that the big part is the intercom not being a "high noise" intercom.  I looked up the SPA-400 that Guy has and saw the 400N for high noise.  Looks like I may be ordering one of those.

I use either a icom a -24 or a a 22 handheld  through a sigtronics  SPO22 N  intercom.......  the N is for noise reduction circuit desigined for  2 strokes.   Headsets are Peltor  - We sell them but I forget what model it is.



I will look it up if you need to know.

Thanks Dave. My 5DX has a noise canceling mike that is spose to be good for 120 db ambient.  I think I will try the high noise intercom and see if that does it.  I know when I talk to the passenger you can really hear the cockpit noise, but I have talked to other guys in the air and while they heard the background noise the transmissions were plenty clear for him the carry on a conversation with me.  I think the tower is just being picky about me flying through his airspace.  There are float planes crossing through about every 10 minutes on the way to and from the local hot fishing spots so I think he gets tired of dealing with us lol.

John:

For the benefit of others on the post.



The ham rigs are FM not AM not that that would have a lot to do with the

clarity required to send a decent voice signal.  A Larger consideration

would be the side tone.  Ham rigs seldom, if ever, have side tone.  With the

side tone the pilot should be able to hear the outgoing signal unless there

is an interfering rf on the same or near freq.  Experience shows me that you

will hear localized RFI (radio frequency interference)



All that aside I'm using an Icom IC-A24 with a set of AC-200PNR headphones.

I power only using batteries but I do have an external 1/4 wave whip

antenna.  Gander International airport is around 30 mi. away from where I

normally take off.  Only once was the tower not able to hear me in my 582

powered Kitfox.  On that occasion a fault shorted the resistors in my plugs

after taking off and the tower couldn't copy me even though I was only a

couple of thousand feet from their antenna array. With a whole lot of work I

did get my destination to the tower and was cleared to leave the zone.  When

I was ready to land I pulled the throttle and was able to easily get through

(30 mi.)to notify the tower I had arrived home.  Before and since that

occasion I've have no problems at all.



I generally only turn the radio on if I'm in the vicinity of an MF or in

controlled airspace...  I also carry an extra battery for Mr. Murphy  and

his law.



Noel
