Hi   

I am in the final stages (yeah right!) of wiring my panel. I have a GNS430W and an SL30 amongst other toys. I am wondering which will be most used from a comm perspective. I plan to have a flip / flop on the stick and would like to make the right choice as to which radio is connected to the switch.  

Any comments / opinions?   

Cheers

As a datapoint, I use the SL30 for ATC since I don't know the frequencies  

ahead of time and have to twist them in anyway.  This free's up the G530 for  

AWOS and UNICOM since I look up those frequencies from the database rather  

than twisting them in.  



Don't have any  flip\flop buttons on the yoke, so can't comment on that  

point.



Hope that helps.

Les,

  

 I am with Robin,

  

 I have the 430W and the SL30.  I have my Com1  Nav1 on the 430W.

I do just the reverse. Comm 2 is always my WX comm. Here is why: 

 

430W  

Transmit power: 

10 watts minimum; 16 watts minimum (GNS 430A)

  

SL30

Transmit power 8 watts (carrier power) 

 

My G900X has dual 16 Watt comms. Nice to have J 

My 8A with a 430/SL30 has 1 - 16 Watt Comm & 1 - 8 Watt Comm. Use the 16 for all your primary communication IMHO.

I guess just to be different……I have it the other way around.  I use the SL30 for all my primary comm and the 430 for my primary navigation.  I have the sl30 hooked to my Grand Rapids and I can push freqs from the GRT system to the sl30.  I have a freq flip/flop on my sick hooked to my SL30…….

 

I think it may depend more on how you plan on integrating and using your EFIS, etc.  I really thought I was going to use my EFIS more to control the radios than I really have.  I think my old age is catching up with me and I just go to looking up freqs and putting them in the radio instead of using the efis to look them up and push them over.

I have the SL-30 functioning as COMM 1 and the 430W as COMM 2. I do push VOR freqs from my Chelton into the SL-30 sometimes, but that is not a major factor for me. I can't tell you any particular reason I made that decision back during the build, but I am glad I did. (It is entirely possible that Stein recommended that setup, I just don't remember) The SL-30 is a really great radio IMHO. The ability to monitor two comm freqs as well as two VORs off of one radio is awesome. My VOR needles on the Chelton point to the primary VOR as well as the secondary or standby VOR in the SL-30. I have the flip-flop switch on my stick set up for COMM 1. My stack is set up with the SL-30 above the 430W, so maybe that is why I made the decision. Bottom line, it is probably not too important unless your EFIS setup makes one radio or the other preferable.

I have my 480 set up as comm 1 and the SL 30 as radio 2.  Both excellent radios, I end up using the 480 as primary mostly because it is hooked to the better of my 2 antennas.  I used the Bob Archer foil for comm 2 and while effective it's not quite as good so I use it mostly for ATIS and local traffic comm.

Not sure why you bought the optional extra power on the 430, but for the 

majority of folks with a standard 430 the power output with it and the 

SL30 will be identical at 8 watts.

I have sl-30 #1, G-420 #2. Not sure there is any real reason to prefer one over the other, although a minor point:  G-420 has an inhibit input so the receiver is off when transmitting on the SL-30, to prevent any feed thru if it happens to be selected on the audio panel. I don't think the SL-30 has such an input (?).

The difference in receive & transmit between the 430W & SL30 is noticeable

30-80 miles out.

Of course, when you are pushing 16 watts of a 430A vs 10 watts of a 

standard 430W. 8 watts of the sL30 vs 10 watts of standard 430 is not a 

meaningful power difference. Any detectable difference would have to be 

explained in antenna differences.

I believe any comm. radio would have an inhibit input line on it lest the

overwhelming power from a transmit antenna just a few feet away would

overwhelm the input of the second radio if not damaging it.

I'd go with what radio sounds better as my primary.

My 2 cents.

There may be a power difference between the radios, but at 2 1/2  

years and 400 hours, I have not been aware of any difference between  

the two. If anything, the SL-30 seems to be the stronger of the two,  

but not significantly. Perhaps that could be antenna issues on my  

airplane? At any rate, 400 hours with lots of IFR and no comm issues  

at all using the SL-30 as primary. I feel like the radios that Garmin  

bought from UPS (SL-30, 480, and GTX-330?) are superior. No  

scientific reasons, just my feelings.

Mine is just like David's....the SL-30 is Nav1/Com1, and the

GNS480 is Nav2/Com2.  I think it does make sense to plan it

partly around your EFIS.  The SL-30 is about the easiest

to integrate for many people, and in David's and my case,

you can use the standby NAV to effectively have it draw

TWO NAV radio needles on the EFIS....so if your other

Nav/Com/GPS has one, it's like having 3 in the plane.  The

SL-30 is the perfect fit for us Chelton users, because it

allows our EFIS to populate the frequencies for both ILS/Nav

and COM, right from the Chelton Database.  It's a great

radio and even manually entering freqs it's what we use

for our primary radio.  The ability to monitor a 2nd comm

freq is awesome.  I can do the same on the GNS480, but I

do it all the time on the SL-30.  Even flying to OSH, I was

talking to the guys in my flight on ACTV, and listening

to Fisk on STBY.  Since my GNS480 has the same ability,

being an apollo product, it's like having 4 COM's and 4

NAV's in the plane.

Then, as others have said, I tend to do all my radio

work on the SL-30, and on the GNS480 that leaves me free

to tune in ATIS, call flightwatch work with FSS, or

whatever, and I'm not punching buttons on it all the

time.  I can also use the 480 to pull up NRST VOR,

NRST Airport, and all the other good stuff since it has

an internal database.

Regarding transmit power, I don't even know off hand

what the transmit powers are anymore of my 2 radios,

but in 750+ hours of flying, both of the radios have

been flawless with belly mounted COM antennas.  Ground,

Tower, ATC, and everyone else, has always had no

trouble talking to me, and I've had the airplane in

so many places that it's pretty much proven itself.

Hi



Thank you to all that expressed an opinion on this thorny question. It

sounds like a split deciusion from those who are flying. Perhaps I need to

break out the magic eight ball...

Or more appropriately, break out the magic manuals and learn

about the EFIS system you choose, and the rest of your stack,

to learn which plan makes sense for YOUR plane, and YOUR

avionics.

Just a quick comment - I have a 430W and an SL-40. Aerotronics put together the panel and they set up the comm flip flop on the stick to change the PS9000EX, not the radios. I hadn't thought about it until now, but if you're listening to two different frequencies, those are most likely the ones you want to transmit on.
