    Subject: Radio interference when receiving
    I have a new Jabiru 2200 (85hp) installed in a Murphy Maverick with an Icom IC-A200 panel mount VHFand an external antenna mounted throughthe fuselage skin midway between the cabin and fin using the fuselage for a groundplane. I am picking up ignition interference when receiving which increases with engine speed. I have tried running the radio from an independant power supply to eliminate installation wiring and still get the same problem, which seems to indicate that the antenna is picking up the radiated noise. The engine has suppressed ht leads to the plugs but I am not sure about the leads to the coils.I checked the rotor arms for security and they seem fine. Does anyone have any suggestions on how to cure the problem? Geoff Leedham

    I'm planning a PIDG terminal order and can't find this nugget on the skytec website: anybody know the stud sizes for the various terminals on the SkyTec Lycoming PM starter? Want to be sure I order the correct thing. TIA, Bill B.

    Subject: Marker Beacon Antenna
    An old topic but I could not find the information. I plan to install the marker beacon antenna on the lower cowl of a RV-7 and have a couple of questions: 1. Is the 40" length mandatory or will 32 to 36" work? 2. Can the antenna be made from coax with the outer braid and insulation stripped leaving only the center wire and insulation as the antenna? 3. Can the antenna be installed along the upper edge of the lower cowl or will the vertically oriented fiberglass (side of cowl) mask the signal? 4. Does the antenna have to be straight for its entire length or is a 90* turn for the last 6" acceptable? A lot of concern for a system that will be gone in a few years but it's there so I might as well use it. Thanks in advance, Roger, RV-7 Finishing

Gang: I am planning a minimalist glass cockpit, and find that my EFIS will output serial altitude data directly. Anyone have a list of which transponders will accept serial input? I know that the Garmin GTX-327 does. What about the -320A? What about any of the new NARCO boxes? Becker? Microair? Others? (Keep in the in range of $2000=B1 GA units. I know that the fancier $datalink$ units all do.) The serial-Gillman converter is about $250, which gives me some lattitude in selecting a slightly pricier serial-compatible unit.)

    I made mine 40" and curled the end round over the last 6"...It works great. I stuck mine in the bottom....Unless you intend to fly approaches inverted I would do the same again..:) Like you I stripped a length of Coax. One piece of advice, make the connection where you can reach it thru the oil door. I put mine on the other side, amazing how many times I've had to remove the top cowl again after forgetting to hook up the antenna.

    Subject: So you can't wait for window's Vista?
    So you can't wait for Windows new Vista to be released this week? Saw a review of the final version on PC Magazine online, today...Here's some of the results of the testing and review that PC Magazine did on it. They tested the SAME versions that you'll get in the store, and on all types of new machines, laptops, low end, high end, minimum memory and speed, maximum, etc... I only included some more general cons, but you'll hear about all the claimed pluses from Windows ads that you will be seeing shortly. Of course, they probably won't mention these... Looks like it needs a lot of work yet to improve on XP... Harley ------------------------------------------------------------------------ Vista won't let you install over an OS that has a C:\Users multiple-users folder. I didn't realize this until after I'd started the installation and typed in my Vista product key. When it came time to choose between a clean install and an overlay, the overlay wasn't an option. So I moved my Users folder. But now the install wouldn't take: Vista thought I'd already completed installation. It took me days to straighten things out Vista's real competitor, though, is Windows XP. For many users, XP is still good enough. And for all the advances in Vista, it's hard to avoid seeing the things that aren't as good as they could have been. Nor is Vista bug-free. As I assessed final code, I ran into a variety of small but annoying glitches and found plenty of features that didn't work as seamlessly as I would have liked. I can't shake the feeling that Vista's release was rushed. Hefty hardware requirements. Minor bugs and rough edges in UI. Lack of a killer app to compel adoption. Many features also available for Windows XP users. Vista offers improvements over Windows XP, but most of them are conveniences rather than essentials. Incompatibility issues with latest graphics card drivers from ATI Some games were more sluggish than in Windows XP Pro. Had to uninstall Norton Internet Security Had to remove McAfee security applications You can't back up your entire system if running a FAT32 file system. Drive Encryption did not recognize the Trusted Platform Module; you'll need an NTFS file system, TPM, and a BIOS update to run BitLocker. Vista did not recognize the integrated Sierra Wireless EV-DO card. Screen orientation, arrow, and escape buttons on the tablet screen do not work. Had to convert the file system of the C: partition to NTFS before proceeding. Installing Vista is a lot slower on a budget PC, taking over 3 hours You might do better with Vista Home Basic. But if that's what you choose, you'll need to install it fresh and reinstall all your applications, because you can't upgrade to Home Basic, only to Premium or Ultimate. Office 2003 works just as well and as fast as it does in XP, so you don't have to upgrade to Office 2007. Integrated graphics and 512MB of system memory just aren't enough Slow when installing programs, playing games, and encoding video. Media Center works, but loading video is slow. Bugs appeared in older games Vista did not support ATI's CrossFire Installer did not autodetect all components, 32-bit programs are installed in a Program Files (x86) folder, which can cause problems for older installers that don't like parentheses in their folder names. Video became garbled after 15 minutes of viewing live and recorded TV.

    Umm, what does this have to do with aviation electrics? Not to mention it's scary that a PC rag writes a review on a product when they obviously can't do it objectively. Half of the gripes below are because of vendor drivers, not Vista and the other half are RTFM items. He's also running the 64 bit version which is not the norm for the average consumer (you can tell by his x86 comment). Lots of things should keep the average Joe from switching to Vista as XP is just fine and there is always OSX or other UNIX variants for those inclined or adventurous, unfortunately this so called review missed the mark.

    Subject: Re: 8AWG Wire to Fast-On Connection
    Bob, The Fast-On connection is to a mosfet switch solid state relay sold by perihelion design <http://www.periheliondesign.com/powerlinkjr.htm> rated for 35 amps continuous. But your statement "30A is pushing a Fast-On pretty hard" got me thinking, which generated more questions, so now I need some guidance. I am using the a Z-13/20 architecture that is modified for a battery in the tail cone (RV-10) The solid state relay is for the endurance bus feed. The circuit goes from the battery to a 30 amp ANL limiter to the relay and then to the endurance bus, the run is 17 feet. The continuous e-bus load is just under 10 amps, but the maximum possible load is 30 amps (no diversity at all, everything running at once, flaps, auto pilot servos, com transmit, etc). The drivers for the high load are pitot heat and landing light. [I know it could be debated whether or not these deserve to be on the e-bus, but IMHO this design is to allow me to fly safely in IMC and land] So, if my calculations are correct for a 14 volt system: a] 10 amps @ 17 feet 10AWG has a voltage drop of 0.17 volts b] 10 amps @ 17 feet 8 AWG has a voltage drop of 0.11 volts c] 30 amps @ 17 feet 10 AWG has a voltage drop of 0.51 volts d] 30 amps @ 17 feet 8 AWG has a voltage drop of 0.32 volts This is only the voltage drop to the e-bus fuse block and does not account for the voltage drop to the final device. So, I believe I am justified in using a 30 amp fuse, but am I being way to conservative in using 8 AWG wire to account for a very unlikely full max load? Larry RV-10 N205EN (reserved) Robert L.
