Somehow Don's initial reply seemed to disappear into the ether for me. I
had to look it up on Gossamer Threads.

It seems like my signal strength is fine. The HDHR signal meter app
shows 95-100%, but my signal quality fluctuates. Sometimes this is
between 90% and 60% and back again in the space of a couple of seconds.

Thanks for the tips everyone, looks like I'll be climbing on the roof
over the weekend.

Cheers,
