Getting ATC involved. Did you make sure your reg number was set (instead of anon) ? Which ADS-B unit do you have?" Thanks for the replies. The unit was working fine but then I relocated the transponder and made an extension cable to fit. I suspect this might be the culprit. Just strange that Flightaware (uses ADS-B data) sees me but the FAA does not. I will have to go back thru my flight data to verify ground speed but suspect data from GPS to transponder. I have an ADS-B test set so I will check output. My transponder is a Trig TT22 and the GPS is a Safe-Fly 2020 from GRT. -------- KC1DNJ General Radiotelephone Commercial SEL A & P Building scale P51, rebuilding Tailwind W10 Read this topic online here: http://forums.matronics.com/viewtopic.php?p=511171#511171 ________________________________ Message 2 _____________________________________ Time: 08:57:42 AM PST US Subject: AeroElectric-List: EarthX Battery Charging Graph From: "user9253" Suggested Changes to EarthX Graphs: https://earthxbatteries.com/dual-bus-lithium-battery-design/ Remove "TIME" from the graph. Relabel "Voltage" to "Voltage Regulator Setpoint". Of course the setpoint will not change unless adjusted by a mechanic. The graph shows what battery charging current would be at various regulator voltage settings. Putting a diode in series with a battery has the same effect as reducing the voltage regulator setpoint. -------- Joe Gores Read this topic online here: http://forums.matronics.com/viewtopic.php?p=511172#511172 ________________________________ Message 3 _____________________________________ Time: 10:13:20 AM PST US From: Bob Verwey Subject: AeroElectric-List: Motor reversing circuit for trim servo motor using automotive relays I have converted a Luscombe manual trim to work with a linear actuator. 12v. Momentary rocker switch on control stick. While the internet abounds with circuit offerings, I am aware of potential "noise" elements and there are probably a few best practices to adhere to. Any circuit suggestions appreciated. Best...
