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. Charles Reiche ----- Original Message ----- From: Don Curry Sent: Sunday, October 28, 2007 7:10 PM 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?

Capen" Subject: Avionics-List: 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 ________________________________ Message 3 _____________________________________ Time: 06:12:11 AM PST US From: "Ralph E. Capen" Subject: Avionics-List: SL-70 issues 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 ________________________________ Message 4 _____________________________________ Time: 07:05:09 AM PST US From: "Greg Young" Subject: RE: Avionics-List: GX-60 - simulating speed on the ground 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.
