| Subject: | Altimeter Question |
Would it be possible (or legal) to bypass the new altimeter's internal
encoder and retain the Transcal encoder?

Encoding altimeters are VERY EXPENSIVE to maintain as a
altimeter/encoder
system. It is much cheaper in the long run to keep these separate. Call
up
Kelley Instruments and ask how much an overhual is on one of those
units...
you can buy alot of regular altimeters and encoders for the price of 1
encoding altimeter overhaul. That Trans cal ssd-120 should last a long
life
for you.
As an avionics tech and installer, I emplore you to keep your 3 pointer
system with separate encoder. Save yourself the heartache of failed
pitot
static inspections and costly overhaul bills down the road.

Subject: Avionics-List: Altimeter Question
I'm considering replacing the standard, 3-pointer altimeter in my
single-engine aircraft with a counter-pointer type. The candidates are
an
AeroMech 8141B, an ARC EA-801, and an ARC EA-401. Does anybody know
these
altimeters and/or have any advice on making this change? Since all
three
counter-pointer altimeters are the encoding type, I would have to remove
my
Transcal SSD-120-30K encoder. Is that a wise move? Does anybody have
the
pin-outs for the cannon-plug on the backs of these altimeters?
Thanks in advance,
Don

| Subject: | GX-60 - simulating speed on the ground |
Fellow tron-chasers,
I'm doing some autopilot testing in the hangar to make sure that things are commanded
as designed.
One of the tests involves GPS steering (S-Tec System 30 with GPSS) and requires
velocity to a destination in order to send proper signals to the steering converter.
Has anyone been able to get their GX60 to think it's moving in order to output
roll signals?
Thanks,
Ralph Capen

Fellow tron chasers,
I'm having trouble with my SL-70 transponder. When I turn it on it immediately
says FAIL. When I turn the little knob it displays the individual test results
which all say PASS except SYN, RECV, and TRAN; which I'm taking to mean that
at least the radio portion has issues.
It still reports the correct altitude to the GPS which I'm taking to mean that
the external encoder is OK and the serial connection to the GX60 is OK too.
The attached antenna appears to be intact.
Any recommendations on things to try before I send it in for repair?
Thanks,
Ralph Capen

I don't know if it will do what you need but there is a simulator mode. It's
controlled by a jumper on the connector. Pin 7 on the 37 pin connector goes
to ground (pin 25) for normal operation. If open it's in simulator mode.

Greg Young
