    Subject: Re: Flightline harness
    I am installing a Flightline FL 760 transceiver in my RV-7A project. I bought the wiring harness from Aircraft Spruce with jacks attached. The wires are labeled for the most part but 3 wires have me confused. There are 2 wires soldered to the ptt tab on the mic jacks. One wire goes back to the harness and the other wire is loose with no label. This one would route to your stick-grip mounted TRANSMIT button . . . Also there is a wire from the harness labeled ptt intercom. I'm not sure which wires should be connected to my ptt switch on my sticks. This wire goes to a separate button on the grip for INTERCOM. I have researched this on the internet with no luck. The wiring schematic provided by the manufacturer didn't cover the extra wire from the mic jack. Any help would be appreciated. Thank you, Tim. Way back when I was selling MicroAir, I did an installation manual for the transceiver which you can download here. http://tinyurl.com/m7mj7rk I don't know that the pin numbers on the radio are the same as what you have but the functionality is the same. This 'more complete' wiring diagram is an example of how your radio would be wired. Bob . . .

A properly bucked rivet swells to completely fill the holes in a sheet. It seems unlikely that insulating naterials would persist with enough contamination to seriously degrade the conductivity . . . besides, there are so many! But things can happen. For example, I saw a King Air out at Mid Continent getting pressurization checks after some major refurb including a paint job. Seems that the chemical stripper used to prepare the airplane for paint etched metal away under the rivet heads. During pressurization checks, thousands of rivets were found to 'bubble' when soaped. This would place the conductivity of the airframe in doubt as well. If stuff got in and ate material away, then 'gas tightness' is lost. I don't think the new assembly methods necessarily degrade rivet conductivity but for sure, environmental stresses (and over zealous painters) might offer an alternative reality in time. Bob . . .

So i want to >take more than one of these units and create a flashing beacon light. Okay, we're mulling over the options for producing a white flashing beacon not unlike those sold as strobes. This brings to mind an array of lamps that is flashed about 60-90 times a minute with a duty-cycle on the order of 10%. The cool thing about the short duty cycle is that you can drive the lamps with greater than their continuous rated current without overheating them. This lets you get brighter flashes than might otherwise be secured with simple on/off flasher circuits. Doing the flasher for controlling 12v to the lamps is pretty simple. The venerable 555 timer has been incorporated into dozens of light flashing circuits over its 50+ market life. http://tinyurl.com/28tdjz At the same time, you might want to consider removing any resistors in the light assemblies and driving them with a constant current power supply specifically tailored to LED driving. Sorry, there's not a satisfying 'short answer' to your question. To confine a response to simply flashing the off the shelf fixtures you're working with would produce an outcome that's far short of the best we know how to do. Bob . . .

    Subject: Marker Beacon Remote Indicators?
    Does anyone have a resource for 14V White, Amber, and Blue indicators. I am reorganizing my panel and the audio panel (PS Engineering PMA7000M-S) is going to be out of easy field of view for approaches. The PMA7000M-S has pins on the connector for remote lights so it won't be too hard to wire it up. The real problem is that I'm finding it really hard to find small incandescent lamps. I'd love to find some Dialight 507-3914 series 14V cartridge lamps and holders. They're just about the right size. I see them available in white and amber but no blue. There's a hole in the part number series where the blue one was and I've found a reference for them but it says "Obsolete" and stock "0". :( These are either Dialight 507-3914-1474-600 or MS-18235-2BT. Someone probably has a drawer full of them somewhere... Bill

    Have you considered LEDs? There are TONS of sources out there for them. Larg e, Small, Medium... You name it. Just search 12v led indicator on google. I s pent days searching thru the results from google before I decided on which o ne to do. Plenty of good choices. The other thing to consider is that the ma rkers aren't required if you have a different way to identify the fix. There are a very few rare approaches where there is nothing but an OM marker beacon to mark the FAF for a localizer-only approach. In those cases, you c an't get by with DME or an ADF, but the FAF should be identifiable with a GP S that has the fix in its database. Note that some GPS's like the KLN-89B do not have non-GPS approaches in their database (and thus, no unnamed approac h fixes) in their database, but more modern ones like the Garmin GNS430 do. I n addition, as noted above, marker beacon receivers are required equipment f or Cat II/III ILS approaches, but not too many of us do those. There is always the flashing light factor.

    Subject: Marker Beacon Remote Indicators?
    Bill; A quick "Google" search reveals several suppliers with part number 507-3914-1474-600 in stock. (some are the "F" version which appears to be the RoHS compliant model) Also some have minimums which will be a problem - but- http://www.masterelectronics.com shows 2 of the "F" model available to ship http://www.onlinecomponents.com has 2 of the "F" model in stock for $4.95 ea http://www.sierraic.com has 688 in stock http://www.componentsmax.com says they have 51,800 in stock http://www.harrykrantz.com shows 17 available Why not an LED indicator which would have a better service life than the incandescent model quoted??

    Subject: Re: Marker Beacon Remote Indicators?
    Good Afternoon Bob and Bill, May I ask why you want the marker beacon indication? It is/was part of the low frequency range system which was shut down over sixty years ago. It has been retained for use with a few ILSs and some NDB approaches, but such use is rapidly being discontinued. I know of no fix designated by a marker beacon that cannot be found via some other legal IFR data. That is especially true if one has an IFR approved GPS installed. There is nothing wrong with having a marker beacon receiver installed, but you can eliminate an antenna and some wiring by getting rid of it. You might even be able to save some panel space. My vote is to forget about the marker Beacon Receiver. <G> Happy Skies, Old Bob

    Good Afternoon JM, You mention that you need to have the fix in the GPS database to use it in lieu of the marker beacon. That is not completely correct. If there is any other fix along the same course that IS in the database, A distance from that fix may be used. Check out the section in the AIM that has to do with using the GPS in lieu of ADF and DME. That and other uses are covered quite well. Happy Skies, Old Bob In a message dated 3/9/2014 1:33:23 P.M.

    From: "rparigoris" <rparigor@suffolk.lib.ny.us>
    Hi Bob True Rotax alt. alternator can be run from the front of the motor when prop is in tractor mode, on the plane Europa I'm building it requires quite the modification to the cowl and making sure that you have adequate clearance for the slip ring contact for the constant speed Airmaster prop. The cowl is quite close fitting to the motor. I'm not an absolute advocate to $137.50 per amp, but it is driven by the aft side of the motor. A Europa enthusiast was offering a kit to drive an alternator from the aft side of the motor for considerably less than $137.50 per amp. Perhaps all is OK, but long term in service history I suspect is not available. I personally ran scared and purchased a short B+C alternator with a regulator that features Applied Archaic Technology (LR3C-14). Not ideal. Weight further forward. Not cheap. The regulator is probably not as efficient as a switcher. The alternator does not spin as fast as would be desirable. But quality hardware, probably very reliable, you can easily set the set point voltage. It kinda gives me a warm cozy feeling. Set up was not $137.50 per amp, but not cheap. I initially purchased a ND with an internal regulator that was machined to fit a Rotax 91X vacuum pad. Unlike the B+C, no attempt was made to deal with a seized alternator like B+C addressed. In addition the drive gear had a smaller width. I was in contact with a Europa owner with a 6 cylinder Jabaru engine, and he ate up several alternator driver gears with the modified ND alternator.
