Really??
I'm not an owner or moderater of this group, but if I were I would immediately suspend your posting priveleges, unless you (like I have upon occasion) immediately posted a follow-on message indicating my regret about the intemperance of my post. ? This is technical stuff. Not everyone is as knowledgable about these things as others. A bit of compassion and thoughtfullness is always in order. Teaching is good, belittling is bad.

Thanks to jbammi. The dialup group listing was the key.
sudo has nothing to do with networking, directly and is not a security feature for networking
It simply raises your currently active user to have same/similar privileges?to access system?resources?as root would have
Think of it as local "God Mode" in a way.
In the Windows world, it'd be similar to "Launch with administrator?privileges"

Sudo isn't an issue with this setup. The system is behind 2 secure networks, but I get what you are saying.
You need to add you user account to the dialout group
or whichever group is relevant for you setup

please do not un as sudo as suggested, you use unnecessary elevated privileges if you do, this can have other undesirable side effects and a security risk

Re: Short Vertical (Whip) Antenna Matcher
Am I missing the point?? I certainly did not see any kind of antenna there. Or was this just click bait spam to increase someones lookie-loos??

Yes. My 30+ years of unix told me that. But thanks for refreshing my memory. All good.

If you want an S9 calibrator, then set up the Tiny SA in sig generator mode
to -73dbm.
?
If you want a short vertical thingy to observe stuff upto about 15Mhz then
a typical PA0RDT design could be used, probably with suitable attenuation
so as not to damage the Tiny SA.

yes, coarse tuning is done by injecting current into the COIL- and COIL+ pins (different from the power supply ones)
Fine tuning is done by injecting current into the FM- and FM+ pins

Re: Short Vertical (Whip) Antenna Matcher
I am with the other Jim (Allyn). I went looking for an antenna matching device and found something entirely different..something with a function I already have well covered. If it really does exist as you assert may we a link to the dice in the subject field.

Well, yes it does. A group member here was making them not too log ago. They look similar to the S-meter calibrator listed but with fewer parts.

That is how I installed it. It didn't change anything. The documents I checked also said that sudo was necessary.
Thanks.
May require “sudo” privileges.

Re: Short Vertical (Whip) Antenna Matcher
The active probe, as mentioned, would work nicely as a broadband whip amplifier, with a wide operational bandwidth.

Yes, of course, but unless you know that fact the collection of letters 'dBm' is meaningless!
