Hello,

Two questions, please:

a. Is there some way to tell if a USB cable is USB 2, or if it is an
older version ? Some symbol on it, perhaps ? What about for USB 3 ?

Is USB downward compatible for USB usages ?

b. Any recommendations for an indoor antenna for HF (30 MHz) that
would be omni-directional, and really small in size ?

Would like to have something reasonably sensitive that might fit on a
desktop, or on top of the radio itself.

Would it have to be an active-antenna to meet this criterian ?

Thanks,
Bob

small hf receivers come with a simple extend able whip and an internal
ferrite stick for the real low bands... this is adequate if you are
just swling and stuff like that. a separate active antenna would give
you more flexibility in case the spot where the radio is has too much
noise from being near a computer or tv or something like that.
dropping a wire out a window or even running it around the frame of a
window is also a way to hide a bigger antenna. for the most part when
you are inside like that you are going to be more limited by local
noise than signal strength on just about any antenna.

Re USB: So far, I've had few issues intermixing USB 1.1 and USB 2.0
devices. The one exception: my old Win-98 laptop doesn't like large
thumbdrives. Maybe it doesn't understand them; they're supposed to be
driverless but the laptop asks for the driver, anyway. New laptop, no
problems.

I have several brands of USB 1.1 and 2.0 memory modules which work
fine on either my old or new computers, with a transfer speed
difference, of course. I have a couple of USB hubs and they seem to
work fine, too. One computer does warn if I'm using a high speed
device on a low speed port, but it goes ahead and works as soon as I
close the warning.

Win98 needs drivers installed for any USB device. That was the one
thing that pushed my into Win XP. Win XP has generic drivers for
most common USB devices.

There is no difference between USB 1.0 and USB 2.0 cables.
