I believe I read, awhile ago, when RXing the FM birds, DO NOT have the "squelch". I believe I may have had mine open, and did not get any data. And thoughts ? W1FXX

SATPC32 GS-232 Rotor Control Protocol
by Robert Bruninga 28 Jan '19

28 Jan '19

A student is trying to build a rotor control to work with SATPC32 via COM1. He wants it to use the "Waaa eee" (AZ/EL) or the AZaaa ELeee Easycomm formats. When we set SATPC32 to track a satellite, it does not seem to send any elevation and only uses the Maaa Azimuth output. How do we tell SATPC32 to output both AZ and EL in either format? Bob

HRD tracking errors
by Francis Geraci 28 Jan '19

28 Jan '19

I use HRD Sat., SatPC32 and Amsat Droid. SatPC32 and Amsat Droid agree on position of FM birds, HRD shows some birds 30 min. earlier than expected. Mainly, AO-91 and AO-85. Anyone else noticed this tracking error ? I have "poured" thru ALL HRD's settings, reloaded keps, etc. Nothing seems to correct this tracking anomaly. Grrrrr. Best to All - WB1FXX

eAntenna
by Les Rayburn 28 Jan '19

28 Jan '19

Wondering if anyone has experience with the eAntenna LFA DUOSAT antenna? My satellite antennas are mounted in the attic of my HOA home. I’m using an Arrow Alaska Antenna, mounted at about 10 degree elevation on a TV rotor. http://www.eantenna.es/?p=3325 The LFA design claims to be a low-noise antenna, which is why I’m interested. Gain is not the limitation of my system, but rather nearby noise sources from my own home and neighbors. If the LFA could reduce that noise, it might offset the lower gain vs. the Alaskan antenna—but I’m not confident. Anyone have direct experience with this antenna? 73, Les Rayburn, N1LF 121 Mayfair Park Maylene, AL 35114 EM63nf Member WTFDA, IRCA, NRC. Former CPC Chairman for NRC & IRCA.

Yaesu G-5500 Elevation read
by Vincenzo Mone 27 Jan '19

27 Jan '19

Hello, today while I was doing satellite activity, I had not under the eye the Yaesu G-5500 control box. I have turned my eyes to the control box and have noticed that The Elevation needle on meter shows 0 degrees. The antenna are moving because if I press the UP button I can see the Antennas moving UP while if I turn them Down I can see them going down. The only problem Is the needle on the meter that does not move and it is stopped on 0 degrees. The Azimuth side is OK. What could it be? Something in the Control Box? What can I try to see if the problem Belongs from the control box in the shack or on the roof? Any help will be really appreciated. Thanks 73 de Enzo IK8OZV EasyLog 5 BetaTester EasyLog PDA BetaTester WinBollet BetaTester D.C.I.

Yaesu G-5500 Elevation read
by jarda 27 Jan '19

Hello Vincenzo, the G5500 rotator requires 6 wires for azimuth (connection between the control unit and the rotator unit) and another 6 for elevation. 3 wires are designed for motor power supply and 3 for voltage from the potentiometer (angle sensor). It seems that one (or more) of the three wires connecting the potentiometer to the control unit is broken. Then the rotor moves up and down correctly, but there is no signal about the antenna position. The connection between the potentiometer and the control unit must be checked. One wire is used as ground, the other one feeds the potentiometer and the third detects voltage from the potentiometer according to the rotation of the antenna. 73 jarda ok2gz --- This email has been checked for viruses by AVG. https://www.avg.com
