No, 1 cycle per second is 1 Hz 1420 MHz = 1 420 000 kHz = 1 420 000 000 Hz An old but still valid introduction to this matter http://www2.jpl.nasa.gov/radioastronomy/radioastronomy_all.pdf

Yes, I know where You found that. For details would it be intelligent to ask the person who put that on the internet for whatever reason ?

your PC is not to old for an upgrade 160GB HD, Intel 4CPU 3.60 Ghz, 2.00GB RAM, 82945G express chip this means the upgrade from vista to W7 is easy as drivers especially for Win7 for Your chipset are provided by Intel here...

Your last 4 questions relate esp. to lasers. Read a book on that basics before ocupying Yourself with quantum chemistry. In that field, electrons will dance weird orbitals esp. when " the atom is a multi-electron one" TheTruth is, nobody "understands complete" QM, because of its weird quantum...

OK, which simple question should I answer? is this a good one http://arxiv.org/abs/1303.6878 ?

data sheets are provided by the manufacturer, not the seller Yes, there are specific formulas but for each piezo there is another one, depending on materials and them are business secrets. use Your favourite search engine to find data http://lmgtfy.com/?q=piezo+data even the first answer...

when the responding frequency is fixed, the delay applies to the phase. A rate is a proportion of a distortion in size in % and depends on the apllied frequency. The biggest distortion is on the resonance frequency of the piezo. Data are provided by the manufacturer. The piezo returns fully to...

Would it be intelligent to ask the person that offers that paper ?

You wanted first an uninteruptable power supply and now it should be totally disconected? o0) You should know what You want. The Diodes in the link disconect either one line or the other line totally, as current does not flow back while charged. But when needed because of impact, current flows...

the observation is the expansion, so if this is no sf, what then? beyond the main stream? anyway IMHO the wrong forum

3m to 6m - I wish I had that opportunities... but try to contact other HAM Radio Astronomers This guy received Voyager 2006 with his 5,6m Dish 3xfar as Pluto http://www.qsl.net/ct1dmk/dsn.html For deeper space communication You´ll need something like this: its an old but excellent...

Which driver is unavailable for upgrades? If You do not feed Your helper with details about Your HP Modell - how should I help?

charger ---Diode----Battery----Diode----Load charging circuit dimensioned for maintanence load of the battery or something like this http://www.ccareswa.org/resources/tips/061220.php

:biggrin:

Please allways post main system information: Manufacturer+Model Number (RAM size, CPU-speed if available) My crystal ball´s broken so I have to guess...Desktop-PC with cards on mainboard? Vista is born as an inflated resource-eater - who could, avoided it and jumped directly from XP to W7. Make...
