Re: ST-60 speed calibration
These days, no major corporation puts the engineers on the telephone, sadly. Or helps customers to modify circuits beyond "adjust that trimpot", if that much. I agree that it would be nice if they DID go that extra mile, but unless you find a really small company where the guys who answer the phone aren't firewalled by lawyers and accountants...that's not unique to ray-ma-whoever they are calling themselves this year.
I've found their phone support to be reasonably courteous and prompt and on-point in the past, but then again, I haven't asked them to do anything beyond what a customer normally would need assistance with. Modify the circuit? Who knows, who designed it, where it came from, how old it is, whether anyone is intimate with it beyond the usual r&r by the book these days?
The only time I asked them to do anything unusual, was when they were changing names and we had half the displays with Raymarine stenciled on them, and the other half with Raytheon still on them. I called up and asked nicely if they didn't think we'd both look better if they all said the same name, whatever name that was, and they just shipped out a whole new set at no charge. Most corps would have offered to sell us new ones.
Modify a circuit? Track down an engineer and have him invest an hour or two in seeing IF the mod is even possible, when the problem is incorrect installation? Just doesn't same so unreasonable to me, that such a big corporation can't be that flexible, or spend that much money on it.
If it is in the wrong location, there's no guarantee that a modification in the circuit would help, since the error might not even be linear. Most reliable solution would be to place the transducer properly, rather than start hacking up the circuit with no assurance that it would work properly over a whole range afterwards.
