 |
|
Someone was asking on this forum about issues with the Icom antenna junction
box installed in their plane. I put in one of those in between my SL-30
Nav/Com and my belly antenna on the RV-6A. I've had a lot of scratchy and
not so great transmissions/reception on that Radio. I didn't think that
maybe if would be that junction box. I like the idea because it makes it
easy to plug in my hand held and use my outside antenna. But I've never had
to do that so if the junction box is causing crappy tx/Rx on that radio I'll
take it out of the loop. I know the SL-30 is a great radio so this has
puzzled me since I finished the RV. Did whomever it was figure out whether
the Icom junction box was causing radio Tx/Rx problems or not? Does the
junction box need to be removed from the loop or is there some I can do to
fix it?
Thanks

It's a simple experiment to take it out and see
if the complaints go away. I'm not encouraged about
'fixing' a poorly performing example of this
product. Best advise is to take it out and add
pilot accessible junctions and coax jumpers
to get your hand-held connected to ship's antenna.

Bob, regarding the coax junctions, what are the specs to look for?

I've never met your radio, but I'd put a small amount of money on a wager that your problem lies in a badly terminated cable - a badly crimped, loose or corroded BNC connector, somewhere.
99% of failures are either the fuse or the connector
