<font color="blue"> (Pretty sure they're in a different freq range (I haven't found it for Ramsey in particular but others seem to be at 533.92 MHz) since the wireless option is now coming out in the larger winches used in vehicle recovery machines.) </font>
They may well be. That was just the first thing that jumped to mind (and an attempt at a little humor). There are all kinds of transmitters in all these unlicensed bands, not to mention interference from things like fencers and VCRs. I mention VCRs as an example, since we have one that interferes with the wireless portion of our burglar alarm. Fortunately, it doesn't set off the alarm because of the encoding (actually, it sets off the built in interference alarm, but we have blocked that from calling the alarm company) .
I seriously doubt that any responsible manufacturer would build a wireless winch without encoding the signal. In fact, that delay you mention may well be due to the complexity of the encoding/decoding process, but being the tech-head that I am, I would be looking for written comfort on the part of the manufacturer. That's just the way I am. /forums/images/graemlins/wink.gif
