Re: Best pc design for SDR
Yes, I was just thinking to some diodes in series ...toggle quoted message Show quoted text
I do so also for the led lighting, I've seen that at 13.8V some does not last, so with led stripes I keep 4 diodes in series and this is vy OK, good light but no heath .
Some car, not too new, may get to 16-17 Volt peak , and it should also be fine to put a coil and a large C to avoid hi-spikes.
With new cars, where electronics aboard is more, the voltage regulators are better, too.
Getting also a model battery pack instead of the car battery may be even cheaper than the PC own battery pack, in some case.
Using the FT-817 a single battery pack could supply both laptop and transceiver, too. But mostly when in /P I use the FT-857 or IC-7000, a bit more current hungry .
I have only to test it; the old laptop is suitable for this, as I do not worry so much if it does QRT ...
73 and thanks, Siegfried !
