We have tried four different GPS fixed and handheld. I have heard that COM transmissions can affect GPS receivers. The GPS frequency that we use is 1575.42 MHz. The 12th and 13th harmonics of our COM transmitters when tuned to these frequencies could cause interference. 1575.42 / 13 = 121.186 1575.42 / 12 = 131.285 What you are describing, however, is different. If I understand correctly, you are experiencing difficulties when you are receiving. I suspect that your COM receiver local oscillator is radiating some small amount of energy at 1575.42 MHz. Hopefully, the path of this radiation is through your antenna and that it can be filtered. I would call NARCO to see if they are aware of the problem and if they have an in-line filter to solve it. You might also want to check with Jim Weir. He has lots of experience with avionics (he designs, manufactures, and markets antennas and intercoms). His e-mail address is .

Only recently have worked on this as I have been trying to keep on track with building process. Recommend you don't buy any of the normal engine monitoring instruments. I should have this inexpensive alternative totally developed in next few months. Available to all FREE! Right now I have display on crt that resembles side view of Cozy. When gear are down, display shows a wheel in down position. Same for air brake. If Brake is too hot, wheel Flashes red. I will then hear " Your left brake is hot" on the head phones. More important, computer recognizes I'm in landing mode and announces "your gear are not down" or "Landing brake not down". If fuel level gets below 10 gallons, it will flash and tell me. When I click the Joystick button, display will switch to my Mentor moving map. However, as soon as an alarm occurs a window will pop up and let me know, including voice in headset. It's a piece of cake to have this same system lead me thru my checklist on startup. It also is capable of controlling the autopilot, but for me that's way lo priority. I offer this to the group only because it can save someone's life. There is a lot more it can do, and anyone can do it. You don't have to be an EE or programmer. There is nothing on the market that compares. Far more powerful than Archangel, Rocky mtn., etc. Looks like it will cost me around $1100.00 (with compromises), not including pc and sending units. Incidently, this uses same approach Rutan used on Boomerang, except he developed custom software instead of using off the shelf. I'm not marketing anything. Just trying to help out.

Although I haven't started yet. I am in line to take advantage of your work, it sounds like a great idea. I also have a line on a very inexpensive GPS board that can be put into a laptop computer and the computer will take output from the board and it can then be used for providing a "virtual tunnel" or something similar for you to fly through to get to your destination. It can also be easily set up for non-precision approaches to landing again using a "virtual tunnel" at the proper glide slope etc.. Lots more can be easily added. Keep up the great work!

Frequency selection is a major pain. You have to watch the cursor, push the single frequency button just the right amount of time to move the cursor to the next number. Many times I push and push trying to get it to switch position. It's saving grace is it's small size. In my LongEZ I thought it was the only way to go. In the Cozy I am building I would buy a traditial type (4 rotary switches) or the new King which as push buttons across the bottom (from 0-7). Then you just punch in the squak. I also purchased the Terra 760D. Didn't like that one either (am I hard to please or what)! It was MUCH!! more noisy than my King KX155 and the side tone was extremely loud. Frequency selcection was a pain (just like the 250). I have always thought King was overpriced, but my king has 10 watts pwr vice 7 watts for the Terra, and it sounds so much cleaner... I pulled the 760D out of my LongEZ (replaced it with a QuiteFlight Intercom) and am putting it in a plane that I am selling... So much for my experence with Terra.

For IFR flight, there are the additional checks to ensure that your altimeter and encoder are calibrated, and that your static system can pass a leak test. (FAR 91.411). Why? Many GA pilots are unaware of TCAS - Traffic Alerting and Collision Avoidance. It's an on-board system that allows a plane to detect all other near-by aircraft that are transponder-equipped. It then displays the other planes' relative positions to the pilot and calculates the potential for mid-air collision. With a TCAS II system (required on all transports with 30 or more seats), the TCAS system has the capability to instruct the pilot whether to climb or descend to miss the other airplane. In order for TCAS to work, we must all have "working" transponders. A slight frequency "pull" induced by poor antenna location or frequency drift of the transponder itself (happens with time) can cause your plane to become "invisible" to ground controllers and TCAS systems alike. Please pass this e-mail on to other pilots; this kind of information can keep us all safer.

Will put it in my VE this WE so can't yet comment on the performance. General specs: TSO C47c Class 1A, weight 1.6 rack .64 lbs, power 11 to 33 VDC @ 12 W, rx sensitivity -74 dbm @90% reply, Mode C capable to 63,000 ft, power O/P 200 Watts. The TX is all solid state so no warm up or cavity oscillator tube to go south ($650.00 for the KT76A tube). Uses 4 rotary knobs for code selection, ident button, reply light. This is a "garden variety" transponder, nothing fancy, just functional but priced below all the others. We opened the cover at the dealers since this was the first one they had seen. The insides look very high tech and beautifully made, several LSI chips and separate shielded RF sections for RX and TX. All the dealers I called were very reluctant to sell me one for some reason but once I explained it was for a homebuilt they loosened up a bit. Garmin have a waiting list and are only shipping to installers right now, so there will be a lead time (mine was 2 months). Tell then you will be installing it yourself in a homebuilt and they will sell you one, strange... Anyway my overall first impressions are very favourable.

Zeitlin Email: marcz@an.hp.com Hi guys, The front panel footprint is standard 6 wide by 1.5 inch high but it is only 7 inches deep, about 2/3 that of my KT76a (which don't work no more due to a fried O/P tube.. ouch). Can't remember where I heard about it but started calling USA based dealers about 3 months ago, some had never heard of it others said they could not get it or wouldnt sell it to me. Gulf Coast Avionics said they would sell me one but only for a homebuilt and would call back with a price but never did. So tried a local Ottawa Canada dealer, Canadian Airmotive, who called me back and explained the wait list thing, but said he could get me one since he was an installer. So 2 months later it arrived, and Im a happy camper since I live right in the Ottawa class D and its been a real pain lately without one. I paid the US dollar equivalent of $1050.00 after subtracting cross border shipping and local taxes. It comes with an alum slide mount tray which has a cast alum end plate that has the antenna connector and the main 25 pin "D" connector. The aircraft wiring plug is supplied along with some other bits I haven't figured out yet. So everything you need to install it (except antenna) is in the box. The installation and user manual looks very good with all you need to know to install it, wire it including pin connections to the encoder, and operate it, plus a bunch of dwgs and specs on certification. Manual part # is 190-00133-01 REV B dated May 30, 1997. They also mention in the manual that Garmin will provide retro-fit kits for the KT76A and Narco AT150. These are alum boxes that screw to the back of the Garmin xponder and interface with the existing mount tray plugs for either of these transponders, sort of plug and play, nothing else to do. Hope this covered it all, just ask if you need anything else.

The Maggellan Meridian XL unit is advertised to track at 800+ knots so would be quit usable for general aviation purposes. My experience with it so far has been in my car and it works quite well within its design limits. It does not have a data base of any kind. It will compute distance and bearing to any waypoint and provide a steering needle type of display as well as plot your actual course with a user selected scale from .2 to 100 miles. It also has the ability to compute ETA, time enroute etc. The unit comes with a mounting bracket and a cable for external power and data connections to a computer. A co-worker that purchased one connected the data wires to a DB9 connector and plugged it into his notebook computer and it worked first time with economical mapping software. I made an antenna extension from RG58U and BNC male & female connectors. It seems to work well in the car with the antenna inside the windshield. I purchased the unit to ultimately use as a back-up to a full featured panel mounted system. It is supposedly waterproof and seems to be quite rugged, rubber armored case etc. John Epplin Mk4 #467 -- frantically building so I can use GPS! From: "Todd B.

BTY, last weekend I saw Chuck Wolcott's MkIV @ Camarillo. Nice job. I'm 6'5" and long-waisted. The fit with NO cushions was very tight. I'm going to deepen the tub, and modify the front seat bulkhead position. My head was up against the canopy. Has anyone used a more "square" profiled canopy to increase headroom? Also, my left foot was bent inward by the tub's curvature, does an elongated nose help this? I'd sure hate making a three seater (one in front only) as suggested by Nat. Also the King Kozy seems beyond me. Martin Orro morro@inreach.com Applied Research and Development Co.

I have a Lowrance Airmap that I dearly love, but I didn't think there was any way to couple it to a Navaid, which I definitely plan to incorporate into the Long. I would prefer not to take up the space and add the weight and cost of a panel-mount unit, just so I can have the CDI function to feed to the Navaid. The one exception to this philosophy would be if the IFR approach-certified units have come down enough by the time I get to that point.

I use the Navaid and it's great. You can program a multi waypoint trip in the handheld gps,and when it reaches each waypoint it changes course all by itself----just like the big boys! This is of course my opinion and not solicted by anyone. Tom Date: Mon, 17 Nov 97 7:36:01 EST From: "Nick J Ugolini" Subject: Re: COZY: Navaid >>I should tell you that there is another way to avoid buying either the Track Wizard or the Porcine Smart Coupler. If you haven't bought your NAVAID yet, just order it with the option for reading the digital data directly. Then it can connect to a handheld GPS, or a panel mount GPS, without the need for a special coupling device. This is another example of Experimental aviation leading the way. The traditional certified autopilots still generally use the old fashioned CDI analogs signals for guidance. In the marine world, all the boat autopilots converted to digital interfaces years ago, when LORANs first became popular. In fact, that is where the NMEA 0183 was developed.>> I ordered my NavAid with the "Smart Coupler 2". I hooked my Lorance Airmap directly to the NavAid AutoPilot and it has the serial converter built in. The nice feature with this converter is the ability to take the Heading signal directly from the GPS, somewhat like the heading bug on a compass gyro. Fly a selected heading, touch the switch, and you will fly that heading. You can adjust the heading L or R in 2 deg increments without resetting anything. Nice. You can also select the course track mode to track your flight plan.

I have the MicroMonitor installed in my Long-EZ and really like it. With the optional 4-way switch, you can switch the display between cylinders to get CHT and EGT on all four. The only gripe I have is that all temps are in Celcius(sp). I still have to do mental gymnastics to figure out what F. temps I have. A cheat sheet on my kneeboard really helps, though This really isn't a big problem for us F. oriented types, as most of the monitored parameters (including temps) have a settable max alarm. Set in the max temps you want, and the monitor will beep (and the offending parameter will flash) if it is exceeded. So knowing the actual temp in F. really isn't necessary. -- Stet Elliott flyez@earthlink.net Long-EZ N321EF From: "Boykin Ed (C)" Subject: COZY: Homebuilt electronic instruments Date: Wed, 17 Dec 1997 16:17:24 -0500 I am going to post this here only once and PLEASE PLEASE PLEASE PLEASE reply to ME and NOT THE LIST. I've started to develop the systems I would need to have an electronic cockpit in my Cozy. I may never actually build it and put it in my plane unless I am reasonably confident I wont kill myself using them (Even if I do use the system in my plane I'll still have standard instruments installed as backups.) If you would like to be included in the discussion of this topic and/or contribute to the design then please submit to me your name and e-mail address.
