Ya Dennis:
Sometimes I wonder what those (Salem, Oregon) guys at UPS AT (previously
Apollo, now Garmin) were smokin when they designed the GA Avionics line. I
just finished wiring my radio stack (all UPS AT bought before the Garmin
takeover, I put both NAV and COM on the E-bus not knowing what you just told
us).
The GX-65 and SL-30 have easy to assemble and install coax antenna
connectors that don't require removing the back of the tray. The SL-70
transponder on the other hand, has as a funky right angle connector that
requires you to take the back of the tray off (with DB-37 connector and
wires) to insert the connector and then you need an E-clip pliers to get the
retaining ring on. Definitely a hassle, especially if you're laying on your
back under the panel (which is the reason I'm installing an access panel in
my top skin).
That seems idiotic enough but this independent power supplies that both need
to be powered to work is ludicrous (I would have powered both units from one
breaker if I'd known that, I was looking to have half the radio working if
the other half went dead but obviously that will not be the case). Oh well,
I just learned that Garmin has also discontinued the SL-30 (they
discontinued the GX-65 a couple years ago) so there won't be many people
running this gauntlet from now on.

I just talked to Garmin tech support, who confirmed that both the
navigation and communication power supplies must be powered for either one
to work

where do you have this information from? I've just checked their website

and SL-30 and SL-40 are still there.
Would be a shame to discontinue that fine line of com/navcom radios!

Dean,
How/where did you hear of Garmin discontinuing the SL30. I don't doubt it,
but it's still listed on their web site.

It would seem especially odd for Garmin to discontinue the SL-30 and 40
series, as they are the VHF components in the GNS-480 as well. Also,
none of the VHF components in the GNS-430/530 compare in quality to the
SL-30. Every navcom on the market, AFAIK, except the SL-30 series use
analog components. The SL-30 gets its flexibility to monitor 2
frequencies simultaneously from doing everything digitally with DSP's
which also improve its sensitivity and spurious frequency rejection. I'd
be surprised if Garmin changes anything until they have a new line of do
everything IFR GPSs to replace the 430 and 480 with something that
combines the best of both.

The only reason Garmin would discontinue the SL-30 is if they could
force buyers to purchase something else that cost less to build and they
could sell at a higher price. The SL-30 is an excellent radio and I
doubt that Garmin will improve on it much, they that doesn't mean they
wouldn't discontinue it for other "marketing" reasons.

Garmin is discontinuing the SL30 ? I just went to their website, they
make no mention of it there. If this is true I hope they are going to
replace it with something even better. Hard to believe though, since it is
such a nice radio a such a small package.

Alternate Viewpoint:
It makes perfect sense for Garmin to discontinue the SL30. Garmin is making
the 1000, 900, GMX200, etc. Those compete with Chelton, GRT, OPTech, etc.
Without the SL30, the competition's customers are faced with installing two
530/430/480 etc for nav/com (a relatively expensive proposition) or using
other older style comms (i.e. KX155), which are relatively outdated in form
and function. Thus, Garmin isn't likely to loose many sales if they
discontinue the SL30/40 - Rather they'll gain business with their other
products and significantly dis-advantage their EFIS competition. I'm not
familiar with many (any) certified GA planes which come with an SL30. So,
there's not much (any) loss there. I'm not saying I like it - but that's
business.
