I bought a Holux GM-270 to use with my C750 and qpegps. I have a problem with signal strength. With the external antennae attached, it works great, even inside the house, good signal, stable lock.
However, without the external antenna, it is hard to get any signal at all, much less a lock. If I lay it down flat, outside, away from any trees etc I can sometimes get what looks like reasonable signal strength on the qpegps screen for 3 or 4 sats, but it will drop one, pick up another, etc. I never get a lock even after 20 minutes. If I hold the Z in my hand I pretty much lose all signals. What I was hoping for was a setup I could pull out of my pocket and get a quick fix on my location. Not pull out my Z, an external gps, and cables. This defeats the reason for having a CF gps
Does anyone else use a holux and Cxxx? Could this be a bad card, or bad combination of hardware?
