What other approaches have others taken? I've got a permanently mounted socket / switch unit from iCom. The panel mount radio and antenna coax are permanently mounted to it, and I have a length of feedline for the handheld that terminates in a plug. If I should need the handheld, all I do is plug it's feedline into the socket. The panel mount is disconnected from the antenna, and the handheld is now on line. Very neat and simple. No making or breaking of BNC connex while flying the plane. I got mine through Pacific coast avionics.

Is it something like Bob has in the Aeroelectric connection, a panel mounted antenna plug, or am I missing something?

You won't be able to measure, let alone perceive, the loss. If it is more convenient to terminate the coax in a male BNC and then use a dual- female bulkhead 'barrel' connector, do so. Case in point, I always put a pair of male BNC connectors with a female barrel connector in-between in every coax to every radio, usually someplace convenient to get to. That makes it easy to temporarily insert test equipment in the line. The losses, even at transponder, DME, and GPS frequencies, are inconsequential.

Alt. field circuit breaker --> AeroElectric-List message posted by: sarg314 Bob: Your diagrams all show a 2-10 Main switch which is apparently hooked up to give us OFF, Battery Only, and Battery+Alt field. I can see the merits of this. But I happen to have a number of high quality, sealed, mil spec. Cutler-Hammer SPST switches that I'm itching to use. Is there any reason not to use one for the battery and one for the alt. field coil instead of the 2-10? This combination would allow having the alt. field ON while the battery is OFF, which is likely to make the alternator unhappy, but is it dangerous? I'm thinking that would come under the "don't do that" heading, like so many other things about flying. Also, you mention in chapter 10 of your book that you like to have a circuit breaker on the alt. field rather than a fuse because of over voltage situations, but you don't explain why it's actually handy to be able to reset this one circuit.

The RAC "Wire schematic" is attached. Do both sets of trim switches (the corresponding switches from grip 1 and grip 2) connect to the points labeled Switch 1, Switch3, Switch4, and Switch2? To me the diagram doesn't make this clear. Does anyone have a schematic diagram of a complete RAC trim system that includes relay deck(s) and indicator(s)? The RAC documentation spreads out the applicable information between the stick grip and the servo manuals and it is more of a pictorial than a schematic diagram. I'd particularly like to see what's inside the "relay deck".

I think they would be fine on something like a dune buggy or snowmobile or sand rail, but are severe overkill for the inside of a cockpit. The screws tops are hard to get off and on, and the chain tends to bunch up when you spin the cap. I sent them back to Powerlet, and they gave me full credit, and shipped the other model with the flip caps (PSO-001) to me in Switzerland at their expense. That's what I meant when I said they were good people to deal with! These connectors are small, and there are *tons* of accessories that use this type of connector in the motorcycle world. They have a lot of the same types of requirements we do. As you mentioned, there are adapters to the cigar lighter connector, and a lot of other connectors. http://www.powerletproducts.com/products/cables.php I bought a cigar lighter adapter, and one for the SAE type cable, which works perfectly with the battery tender. BTW, I think I learned about these on either this list or one of the other fine lists I try to read regularly. -- Mickey Coggins http://www.rv8.ch/ #82007 finishing ________________________________ Message 16 ____________________________________ Time: 04:53:05 PM PST US From: Steve Allison Subject: Re: AeroElectric-List: Van's gauges power consumption --> AeroElectric-List message posted by: Steve Allison sarg314 wrote: > I have a few of van's gauges and their associated senders.

Tom, I measured one gage at 100 mA. (Don't remember which one it was.....and I've made the assumption in my electrical system design they are all about the same.) The light in the gage uses an additional 125 mA at full intensity. Steve ________________________________ Message 17 ____________________________________ Time: 08:05:15 PM PST US From: "Robert G.

I heard today about switches that have a push-pull CB mounted below the switch in the same housing. Anyone have a reference for these so I can research? For the few CB's that Bob recommends, why would I want a separate CB and switch (whether in the same housing or not) when I can get the switch/CB in one smaller package? I know there's a price difference.

This sounded like it was worth looking into. I verified this opinion with a competitor of Direct2. So off I go to study TSO-C146 the Standard document for WAAS GPS, unfortunately there is nothing in the document regarding functional requirements other than a reference to: RTCA/DO-229B (which I learned has since been superceeded w/ RTCA/DO-229C). Another Google search reveals that this document is available but with a cost which ranged from $108-370 per copy. Does anyone know of a 'library' where this document could be 'rented' or checked-out. a couple hundred bucks is a steep price for someone just investigating an idea/thought.
