Here's a quick search on Mouser for an enhancement mode PFET with an Rds of 5 mOhms or less and a continuous drain current of 50 Amps, must be in stock:

Irf4905 @ .020 ohms —. Put two of those in parallel and you’ll get .010 ohms which means you can run 10 A through it and have a dissipation of only one watt. Hopefully once people start returning

USPS delivery varies greatly these days. I haven’t seen mine yet, but today was a holiday in the US. I expect we’ll start seeing them this week. 73 Goody K3NG

Farhan Can’t say. Maybe this week. Will advise when received Art

Art, They were posted a week ago by usps. Do you know how long it takes them? Has anybody received them at all?

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.

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

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

The parts that I suggested have much much lower Rdson which is why I picked them....... Gordon [email protected]> wrote:

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

thanks...that worked.. having a couple of other issues but not related to the code it appers. thanks Vince

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

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:

It may be a step backward for some but I have an assembled uBITX V6 for sale. It has been used very little on SSB with excellent results.? If interested, please contact me by email to discuss

Mac users will need to be running an X11 server (see https://www.xquartz.org/)

Thanks, Jerry. Our County had spent > $100,000 on our group to provide 14 go-boxes with Public Service Motorolla truked radios as well as far less expensive ham radios....because the hurricane

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.
