Angry Synscan - HELP!

I bought my synscan upgrade for my EQ5 last October, and have used it successfully for guiding and tracking without any issues, but whenever I try to do an alignment with it for GOTO, it is way off - WAY off - maybe 15-20 degrees......

Up until now, I have thought it was something that I was doing wrong, but I have been reading a few threads on this forum and others that suggest the handset may be at fault.

However - one thing I cannot get my head around is that if it is the handset, and I am bypassing it using CdC via EQMOD (I am using the cable from the USB-serial converter that plugs into the handset), should it still be an issue?

I tried a few experiments tonight inside to get a feel for what the issue is. The first thing I tried after unparking the mount, was to slew to Antares first with the handset, no PC connection, then with CdC connected via EQMOD. These both gave me the same, way off, position. I tried a star - can't remember which - that should have been just above the horizon, and it gave me 20 degrees below horizon.

I am thinking that I am going to give Ron a call at Sirius Optics, and see what he says.

Any ideas before I do that?

To pre-empt a few:
1. The mount is aligned south with correct latitude set
2. My lat/long is set 27d27m S, 152d 59m E in EQMOD and handset and CdC
3. My time is set to +10.00 hours, and entered in 24hr format
4. clutches are not slipping
5. date is in mm/dd/yyyy format

Cheers
Adam
