I totally agree with this. I've too noticed when running the XV144 at more than 10/15 W the xverter case get pretty hot. The Elecraft guys btw are well known to be conservative about component choice, keeping well within the safe limits. On the other hand, just to keep things less hot I'vee added a small cpu fan over the top holes (the ones over the attenuator resistors) to drag out the hot air. Since then the case has been a lot less warm even at full output for some minutes. To avoide excessive noise from the fan I've connected the Voltage supply for the fan at the 12T point, so it runs only when on tx.
These are my cents on the matter... :-) 73 de Giulio IW3HVB AD6XY ha scritto: Snip > Of course the output will be cleaner if under run, so a 25W amplifier > running 10W ought to be cleaner than when running 25W. > > ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
