Mind you I live in a quiet RF area, so a LNA might not have any effect at all.

BUT... he only measured one as far as I know.
AND... I've never noticed the problem he described, on my 910.
However the folklore in the UK is apparently that the TS2kx is a better radio on 1296.
The folklore is also that the 910 only outputs 8 or 9 watts instead of the rated 10. But no-one talks about whether they have had the power output adjusted. The modules in these radios are rated for 15 or 18 watts, so it is probably only that the radio has not really been set up correctly at the factory.

Do you know of any actual measurements of the IC910 LO on a spectrum analyser? I know the reports done by the Germans are fairly damning of all commercial radios, virtually all models since DDS PLL LOs were introduced.
The difficulty for people who don't want to transport multiple bits of gear around for field use, or who don't feel confident enough to assemble their own even from well rated system components (HF rig, transverter, sequencer, power amplifier, rx LNA), the choices are narrow.
The original question was what rig should someone buy, when faced with the IC910 and TS2000 options. The purpose stated was "getting a weak signal station going" and we don't know what RF environment he will have in his part of Tasmania, but I doubt if it will be anything like the situation it can be in the UK or EU. I also doubt if there are too many other weak signal operators nearby, but I suppose he might add a 1kw amplifier!
We have managed to cast doubt on both his suggested options, so what should he do?
