It was March 31 in my timezone when I posted.

I managed to change U22 in my Tiny SA Ultra. I used an 852D+ hot air soldering station. Used hot air to remove old one and soldering iron and Ersin multicore? 23SWG solder to solder new one. Used a

Modern digital o'scopes contain many useful add-ons which are impossible with the older strictly analog approaches. I'd also suggest capturing the discharge trace on a modern o'scope and using the

Hi there, I would second the recommendation to use a hot-air station for this repair.? With some practice beforehand, you can become proficient enough to do it relatively easily.? We have a cheap

This power cycling method is a good way to isolate the interference and determine if it is coming from your property or outside. I would also get a DSP Receiver such

Madbrain: You are living in a RF hell due to having way, way too many wireless devices. As an amateur radio operator and having deployed some large outdoor wifi networks (2000+ plus devices), I

Wow. Just wow. You have created what we call RF Hell. You will inevitably have a high rate of signal collisions. Also the combined signal level of all your transmitters and EMI generators across all

Hehehehe!? Well done!? Your problem is not even close to the President's Executive Order to eliminate the Amateur Radio Service!? He hints that the IRS is next... -- Dan N1DH Middleboro MA

Hey Guys, April Fool ………

Hi. Let me conclude: 1. You have a huge house with many WiFi components (only talking about that what is running over WiFi). 2. You have a very high number of WiFi components. Phones (1900

Kindly suggestion: never use a graphite pencil as a pointer to components on a PCB. One might inadvertantly create a conductive path on the board without knowing it. This is just a general rule of

How much metal is part of your home's costruction? Roof, exterior walls (metallized insulation, wire mesh under stucco, etc.), interior walls (are the studs wood or metal?), etc.,

Hello. I don't know your soldering shills, but this definitely is on higher level. Forget soldering irons in this case. There are super-fine T12 soldering irons, but the size is still very small.

Within radio range of each other. Jeff

What do you call close proximity ? This is a 4600 sq ft home on 3 levels indoors. There are many smart bulbs outdoors as well. The devices are not all close to each other. There is a fair amount i can

It is most likely that your problem is that you are just swamping the spectrum with so many devices. You are just overloading the capacity. There will not be just one problem so a spectrum analyser

That's really impractical for the hardwired devices, which are many. Flipping some of the 50 breakers works, but cannot isolate a single device such as a switch or bulb. I can turn off power to entire

If you repeat the pulse and use MAX HOLD, the scanning will eventually capture the generated fundamental and harmonics. Depending on the duty cycle of the generated output this "eventually" may take a

Based on the "fault finding" tab at tinysa.org (

I want to measure the frequency spread of a single pulse arising from capacitor discharge into a coil, but it sounds like from the discussion here on measuring radar pulses that this will not be
