Re: Sbitx manual
You could also try the IRF4905 MOSFET P-Channel 55V 74A @$1.50 each which is 0.020 Ohms. The same one used to power the SBITX RF power amp.

Re: #sbitx A cool (kludgy) way to remotely use the sbitx
#sBitx
Oops, yes, if you are running an X11 program on the sBITX, you would need to also install a FULL Linux distribution on your Windows machine, which is another step which I can't remember how to do. But

It's not the "ssh" part that's tricky, it's the "ssh -X" (enable X11 forwarding). No X11 on Windows without heroic measures. As someone else said, an alternative approach that might work on more

Windows 10 and onward includes an SSH client. Just open a cmd window. Can't remember if it needs to be installed. It may be added when you install the Windows Subsystem for Linux. Remember, M$ and

Re: Sbitx manual
Although those Nanos are no-name clones, the key component on them is normally a real Atmel microcontroller. I gather that some clones of the Atmel chip have started to appear; those should be

That's not entirely accurate. VNC does not use the X Windows protocol, It uses its own Remote Frame Buffer protocol, which is a simple one that just sends the bitmap of the screen (compressed to keep

Re: Sbitx manual
Tayda looks like a good steer for a cheap PFET. But be aware that the on resistance of an IRF5305 is 60 milli-Ohms, which is 20 times more than the part Gordon was working with. So if your rig draws

Re: Sbitx manual
If you're looking for a P-Channel MOSFET for a power switch then this may be able to use a IRF5305 - TO-220, 55V, 31A, 0.06Ohm RDS On @$0.78 each:

Correction for the final sentence: If the user does NOT fuse the battery with a fast blow fuse of the appropriate current rating, then a reversed battery can destroy the rig.

Re: Sbitx manual
This isn't a great choice, but it would work for a modest power transceiver such as the sBitx and there are > 400 in stock at Digieky.
