A common problem with qrp transceivers is a weak frontend . Most end fed antennas use low pass tuners causing high stress due to strong signals coming from BC stations .
The High pas tuner used here helps to reduce these problems. Put 19 turns 1mm transformer wire on a T130-6 torroid to form a 4.8 uH coil. The trimmer used is a 60pF compression type set to about 25pF . Put a 3.3K resistor between the antenna connector and the ground of the coax connector and tune the trimmer for resonance at 14.180 MHz.for ssb or 14.030 MHz for CW. Keep in mind that a thin antenna wire has a higher Z. Use hot glue to fix the toroid and the trimmer.
After tuning the unit, connect the half Lambda wire ( 10.15m PVC covered stranded copper wire) and cut it for lowest swr. A 1:1.2 swr is easily obtained with this unit. The cabinet is a PVC type G302 made by Velleman. Every end fed / vertical needs some kind of counterpoise to pusch against and in this case that's the coax , so don't forget a line choke near to your transceiver.

This pseudo-HTTP waterfall mock illustrates a situation which applies to a lot of web sites out there which have legacy code, mixing inline and external script elements and so on.
This was drawn thinking about how inline and external JS (red) elements block and interfere with page load and rendering. We do a pretty good job of "rolling up" our JS, but there is still a lot of up-front time spent in load and parse, which subsequently affects render.
The less script loaded/parsed up front, the faster you should be able to show a page to the user and affect perceived performance, loading, and so on. YUI 3 does a good job of this with their "seed" loader and new asynchronous-based constructor/require() nature.
Needless to say, ideas are being tinkered with.
