First thing to ensure is that the antenna is completely in the clear. After that it may be worth trying another bridge board.
Thanks guys for your suggestions and comments. I have removed the extension cable from the PAW and re-attached the PAW antenna directly to the PAW (that's currently velcro'd on top of the battery under the nose cone). When I next go flying I will try it again.
On the power supply itself, ... I will rectify and fly PAW with the sole device on the Anker ...

Update on my PAW limited range problems ...
I have now wired in a separate dedicated Anker Powerdrive 2 and now
only run PAW from this with a 50cm 20AWG connector cable.
The PAW antennae extension cable has been removed and the PAW antennae directly connected to the bridge board and Brian Montilla kindly lent me a spare PAW bridge board so I've been trying it out on a couple of flights to see if these changes together fix my problems.
The short answer is no, I'm not convinced that it entirely has. With Brian's bridge board in my classic I have been able to see other traffic up to the side of my flight path a maximum of 8 miles away, which is better than I had, but whilst flying today following Jinx who has a Rosetta I found several times that the signal disappeared after about a mile to mile and a half separation.
I appreciate that antennae positioning and attenuation can have a significant effect on signal strength, so its either that I need to extend the antennae again on a pigtail lead, or its the antennae itself that is the root cause of my problems. My PAW classic is currently mounted on top of the battery on the QuikR base tube, so its underneath the flexwing front pod. The antennae is connected straight to the PAW, no extension lead, so is in front of me and behind the glass cockpit and all its electronics.
Although its not connected to any metal parts I am wondering whether the electronics up front is part of the problem and I need to get a pigtail and mount the PAW antennae under the QuikR windscreen or underneath the pod where it can get more 'clear air'?
If so, is there a recommended source of SMA M/F low loss extension leads?
Thanks, Geoffrey
