Daniel, A preamble: this group is loaded with wizards and these guys (and gals) know a lot about stuff. That I recommend other sources by no means discredits

Tim, Do you have to install some firmware on your nanovna for it to work?? And that you have to make sure it is certain nanovna?? not all will work. Firmware is something called Dislord? I have

In this photo, I have not taken the time to calibrate/zero-out my test setup, so the displayed data is far from accurate. I’m only trying to show how I test crystals. The other pic is my test jig. I

Received today from amazon from an order made yesterday:? 3120 pcs 1/4W 5% Carbon Film Resistor assortment kit.? Price:? $17.99.? Trusty HP-35 calculator says $0.0058 per critter. Measured random

I have a partial ADC 20 conversion receiver section built but I'm not sure the 9 MHz IF filter is working properly--I don't have any 9 MHz crystals that have much Q, for one concern. I decided to

Watching this conversation with interest. I am surprised nobody has mentioned using a nanoVNA to characterize crystals. I did this with a bag of 10MHz crystals, sorting to spreadsheet, and was able to

Thanks Steve. I had another thought on this subject last night and I cobbled together a quick test. Stable frequency generators and high resolution counters might not be on everyone's bench. For fun,

You're going to really enjoy the 2N2/40 Alan. I built mine from the kit, and used it as my only rig for the first few months after building it. My entire station was the 2N2/40, a little straight key,

Steve, I want to get a similar tool. Is there markings on the die that show the size and are they in mm or AWG? I ntice some dies have AWG markings and some in millimeter. 73 Mike N2MS

This might be outside the scope of what you're looking for, but I found this video interesting, with good explanations of how the circuit works. This might be a fun "quick" project for a tool to get a

Highly recommend the “engineer” crimping tools like https://a.co/d/gtzCBBd they are not cheap, and you will want to buy all 3. You also need to individually crimp the wire and insulation prongs,

I have to fiddle with mine a bit too. These tools won't be a perfect match to the contact and will not be as good as the tool you buy from the connector manufacturer. (For several hundred dollars

I'll probably be banished for this, but in a pinch (pun intended) I've used needle nose pliers and hand crimped jst/dupont type connectors.? I wouldn't do it for a connector that sees repeated use

Hello Steve. I actually just received a iCrimp from Amazon: https://www.amazon.com/dp/B01N4L8QMW The jaws even the front thin one is more than 4mm so I had a bit of trouble loading that very short XH

I found this tool on Amazon. Has anyone used this tool? <https://www.amazon.com/gp/product/B0D1FR76Q7> Mike N2MS

I strongly suspect all of these "24 values" use the same die (maybe a different one for PNP types), in packages with different markings. I measured noise levels of 2N3904 and PN2222 from aliexpress,

I like Tayda's diecast enclosures and potentiometers Doug. I bought some sub-mini toggle switches from them that turned out to have intermittent contacts, so I ended up discarding them. I've bought

I use these JST XH connectors in my projects. You need the proper crimping tool to do it right. The choice of crimping tool? and the correct position for your wire gauge ?is vital. A lot of the

I gave up on that crimping and went with pre-crimped from pololu.com https://www.pololu.com/category/19/connectors *Headers, housers, pre-crimped male and female wires, etc.* *Works well for the
