I think you for your suggestion. Very interesting result. The HRD rotor interface software does not display what the Yaesu rotor box does. HRO displays 180 degrees regardless where the rotor is pointing.. However when I click anywhere on the map the rotor proceeds to 180 degrees regardless of where I tell it to go. 180 degrees is where the LVB box displays the rotor position is all the time and never moves.

I removed the to of the LBV. I removed the connection from the cale to the connector and reinstalled it. It seems tight. Hoping that might remove and oxidation that might have built up. I pushed the IC down and no movement was noticed. Still the same issue exist.

Hi, I think you refer to the lcd display that does not work. Have you tried to check if the info is displayed ok on a pc using for example the program rotator distributed with HRD (via rs232) ? In that case the issue could be in something wrong between the pic and the LCD display connections.

John,

You will get better answers from other people on the list, but a couple of things come to mind:

1. Do the meters still work on the Yaesu G5400B control box? If so, the

potentiometers and wiring between the Yaesu control box and the rotors are probably OK. If not, check for broken or corroded control cable wires and connections.

2. If the meters work, then check the wiring and connections between the

Yaesu box and the LVB tracker.

3. The next thing to worry about after connections is the 5-volt

regulator and analog outputs from the Yaesu that give the position to the LVB Tracker.

Check the above, then let us know what you find.

Well after working for a very long time without issues my LVB and Yaesu control box have stop talking. The rotor box works perfect with the rotor but the LVB display does not indicate any movement. It just sets at 179 "Az" and "0" El. The switches on the LVB will move the rotor but no display movement on the LVB. Anyone got any idea what might be going on here?

Thank << John
