I used plain old 3 in one

Dirt and dust sticks to 3 in one, and it gets thicker and less "lubey" over time.? There are two products I highly recommend for that sort of thing, both from Caig: Deoxit D5 and MCL Moving Contact Lubricant.? I, and a lot of others, won't use anything else.

So quick attack and slow decay per frequency?
Or only in zero span mode?
Which attack and decay times?

Or another USB cable?

? Quasi-peak detection works more like pulse-width modulation (PWM), the higher the repetition rate the greater the output.? A high repetition rate emission will be close to the value of a peak detector, while a low?repetition rate?emission will be below an average detector.

If so, would it likely go into the tinySA app?

? Best strategy in lieu of not having a quasi-peak detector is to ensure all your emissions are below the peak limit.? The peak emissions should always be higher than the same emissions measured with a quasi-peak detector.? Of course that means that you may spend some time reducing emissions below the peak limit that already meet the quasi-peak limit, but its better than arriving at a test house and finding your device fails the quasi-peak limit.

One of the projects I was asked to 'covertly' develop (one of those jobs where we weren't allowed to share any info with co-workers in the same room what I had been tasked with) was a system to transfer wireless power together with a low data rate (4800bits/s) communications channel to operate across the gap between a door frame and the door (which contained a solenoid lock).

Because it was 4 decades or so ago RF tech wasn't as it is today, so I decided to use cheap readily available parts (costs are always a main concern) which happen to be a couple of 6"ish ferrite rods (as used in LW/MW radios) because they would also easily fit inside a door frame and the door side by side (energy across the 1" gap), I decided on a frequency of 125kHz for the wireless power transfer and comms frequency - might give you a clue as to what it later turned into ;)

Hello iain,
It would be fair to Erik to not only link the first video of Imsay Guy,
where he did not understood (or read) the specified limits of the tinySA.

You should link also/or from Imsay Guy:
#536c TinySA Update: Works well below -30dbm

I never have NFC enabled but thought I'd see how well a tiny RF loop works at NFC frequencies (13.56MHz in this case) ..

Or a different computer, my Dell i5 wouldn't recognize the ID of the tinySA but both my Acer and Toshiba i3 computers had no problems. All have W10.?

Have you tried using STCube?

Did you use a USB 3.0 port? If so please try a USB 2.0 port

I have Windows 10 64bit home on a full desktop; I have tried repeatedly to connect with my tinySA to no avail; what are the proper steps to do this? I'm not getting a new com port connection, and the tinysa APP com interface shows repeats of timeout, no connection

Thank you Bernie!? I wil !!

Welcome to this great group!

Have a look at Erik’s YouTube channel for his excellent videos on the TinySa.

Hello everybody! I just purchased a tinySA and joined this group today. Looking forward to work with the group.
