I am also sure that the OP did this post many months ago and it was
flogged over pretty well at the time. (Perhaps with a different
subject?) The solution from memory was to setup a better/higher antenna
at the pump site and improve the one on the vehicle. Both antennas were
also tuned.

There was also some discussion about tuning the RX better and maybe
lowering its response threshold some. There was also talk about PLI
being the main issue.

But yes it is kind of strange that a "power increase" tends to be the
often suggested solution. I guess it is easy for the mind to work in
that way though - bigger equals better. Advertising also seems to
concentrate more on these numbers. (I mean look at the stupid use of
"megapixels" with digcams, without quoting lens distortion) It would be
nice if the world understood that the desired signal has power as does
the general noise and/or interferring signal. The trick being to have a
ratio or difference between the two "powers" that gives a desired
result. eg 10dB for some digital telemetry modes. This of course opens
up a whole spectrum of possible fixes, many of which can result in a
much larger signal to noise ratios than just increasing RFO!

It is funny how people with problems like this always look to boost
transmitter power, which as noted is not legal, and never consider
improving the receiver end, which is both legal and more likely to
work.
