A handheld has much lower power output than an SL-30/-40/G430, which, added to your wingtip COM antenna, will be very far from a good option for a second radio. I have an extra SL-40 around that I could ship to you to use for the remainder of your trip. I would have to verify with an avionics person that it would fit into an SL-30 tray without problems, which I could test here, since I have an airplane with each here. I think this would work fine, since the COM radio uses one side of the back tray and the NAV radio uses the other side. Basically, this would leave your NAV portion disconnected, but you would still have your COM. You would still be able to use NAV on the G430 as well as the IFR GPS. Give me a call on the number below in the morning if I can help you by shipping this radio to you (after I test the functionality of the swap). This is ! > pr! >> obably the most expensive option because of shipping, although many avionics shops are very proud of their connectors (and time, if they won't let you borrow their crimping tools). This would also save you from having to introduce more loss into your antenna cables by using one of the two options below.

Overall this will create more loss in the system, but it should be fairly low loss if you have good connections. >> >> #3 - The other option is to cut the cable near the SL-30 tray (leaving enough room for a reconnection down the road) and putting a male BNC connector on that cable and connecting it to the G430 COM port (this is assuming that there is enough cable to reach the G430 connector). Then you could either run the G430 antenna lead going to your wingtip antenna to a location where you can hook it into your handheld radio, or making an extension cable with a female BNC on one end and a male BNC on the other end and run that to your handheld radio. >> >> GOD BLESS! >> >> Jesse Saint >> Saint Aviation, Inc. >> jesse@saintaviation.com >> C: 352-427-0285 >> F: 815-377-3694 >> >> On May 11, 2012, at 10:34 PM, Bill Watson wrote: >> >>> >>> Coming into town a few days ago my SL30 went intermittent as we flew thru some storms north of Phoenix.

Bill, I highly recommend that you first, before making any other plans or going anywhere, look behind the panel to see if there is a female/male BNC splice about 6" from the SL-30, which would make the temporary fix very easy. I'll let you know what I find out about the -40/-30 swap.
