While exchanging tall tales at the bar at the RSGB HF Convention over the
weekend the discussion came round to the need for an amplifier specifically
optimised for solo DXpedition use. The holy grail is 500W output on the HF
bands at an all-up weight of around 10Kg. The well known semi-pro MOSFET
amplifier on the market has a dreadful reputation for IMD and is pretty much
unobtainable anyway. Thermionics seem more appropriate, but their power
supplies are heavy.
What is the list?s collected wisdom? Solid state? Valves, perhaps with SMPS?
Theorising is OK (after all, it was a bar room discussion), but what would
really get my attention is a URL to an actual example of a 500W/10Kg
product.
