X-no-archive: yes
In article , Mike Borgelt writes I think your problem is actually in the other gliders. The MicroAir receiver is narrow band. Other transmitters may meet the older specifications but may have a problem talking to a MicroAir receiver. I think that was what the MicroAir designer was talking about at Kingaroy a few months ago. Mike Borgelt Mike, what exactly are you saying by narrow band? Is the Microair 8.33Khz spacing (which we are threatened with)?

I'm not sure of the exact details but the implication was that the MicroAir was tighter than required for 25Khz spacing. I'll ask. Mike Borgelt

Andy,
I have the same situation that you described with my Microair. Just about every glider sounds different and I sure appreciate those with "tight" radios. I agree with Mike Borgelt's reply that the other radios are not up to par. Overall the Microair has performed well (except for the excessive sensitivity) but I would rate the quality of finish and external components (judged by the feel of the pots, etc.) as only average. My old Dittel was really nice... Steve LS-3a AM snip I am happy with mine except that I still have not resolved a problem that a few gliders that I fly with are very distorted and unreadable, while most are clear even when very close.

I have a Microair in my glider and there are a couple
of gliders in our club that I can't understand transmissions coming from their radios. One is equipped with an (identical?) Microair and the other is equipped with either a Dittel or a Becker. Other gliders hear them fine. All I hear is a garbled message. I can usually determine who is speaking by the sound of their voice, but I can't distinguish the words. I do plan on taking the glider to a radio shop and have them check it out, including the antenna. Is it my radio or the others? I suspect it is my radio since others here the 'garblers' clearly. They all say my transmissions are clear. Ray Lovinggood Carrboro, North Carolina, USA LS-1d (In need of a snorkle this year...)

It has a front panel squelch control that can be very useful for shutting out chatter from distant sites while still leaving the volume high enough to hear safety calls from proximate gliders. Other 'top of the line' glider radios have no pilot adjustable squelch.

Mike Borgelt Mike, I suspect you are right nut I have not yet been able to confirm with frequency measurements. Is the MicroAir designed with a narrow IF passband to support 12.5kHz channel spacing? It only allows selection of 25kHz channels. If that is the case perhaps they would consider a design change to widen the IF passband. Has Australia changed to 12.5kHz spacing? Andy (GY)

I'm re-painting some gel coat spots on my LS and was wondering what
everyone is using for the red trim color. The original stuff is Nitro Cellulose Lacquer. So, I call up the local body shop only to find that lacquer is on it's way out of major production. Too bad as it's nice stuff to work with, cheap, light, can be put on thin, and easy to patch. I've found some by looking on the internet but it only comes in one color red and gallons. I'm also re-finishing the elevator and would like to sand the gelcaot and paint it with lacquer. Won't add weight that way. The LS also has some red tape to blend the seal on the rudder. Any idea where to get this red tape? -- Joe LaCour KineOptics 120 Golden Pheasant Dr. Slidell, LA 70461-3116 985-649-0602 Optical & Mechanical Instrument design/fabrication http://www.kineoptics.com/

It's comparatively little used today because glow-engine fuels attack it, but the larger hobby dealers have it -- and if you can't find nitrate, the newer butyrate dope is usually compatible with it. Buy a small sample, test it on an out-of-the-way spot, and you should be able to get a color match with a little mixing. rj

you could also use acrylic laquer, which has huge advantages over over
nitro and no real disadvantage (it can be shot very thin) or a basecoat/clearcoat system, while a bit more work, can also be done thin/light and will be many times more durable than nitrocellulose. Either of these two systems can be EXACTLY color matched and are locally available anywhere at an autobody supply store. Try Ditzler Duracryl for acryl laquer, or Deltron for b/c system, or other types by Sikkens, Martin-Senor, Glasurit, etc.
