I just want to share my experience with the 5TB Seagate Barracuda ST5000LM000 2.5″ Internal Hard Drive.
I am not going to share my own thoughts about this drive her in public.
Instead I will leave it up to you! to do your own judgement.
Back in February 2019 I bought 10 of these drives for stationary use.
After 2 to 3 months, two of these failed totally.
Then in May, I bought one more from a different supplier. Well, this last one lasted for one and a half month.
To summarize; three out of eleven drives failed within three months of use.
I have never seen anything like it before.
UPDATE 2019.09.07. One more drive failed this morning. But at least this one lasted about six months.

Just got hold of a brand new, budget priced Spectrum & Vector Network Analyzer.
It is the SVA1015X by Siglent.
I am heading into testing the unit now, so no time to talk. 😀
Here are some pictures.

Sorry for the site downtime lately.
A server failed and it took some time for me to notice.
But it’s up and running again now 🙂
I was out bicycling the other day, and here is a picture.
Nice shack, a bit hard to reach in winter time, but neat. 🙂

I am so sorry to hear that #Bouvet #3Y0Z #hamr #eme expedition has failed.
I thank you for your effort, and I am sure you will succeed next time.
Santa, ehhh sorry, the postman just brought in a new toy here.
It is a radio, but not HAM-radio, sorry.
It is time to retire my soon to be 30-year-old Sony FM stereo receiver.
The successor is going to be this Yamaha Network/FM/DAB+ receiver, which has all kind of bells and whistles. (Just barely tested it, but it sounds very good)
