Can someone please help me to learn how to crimp JST XH connectors?? I have watched over 2 dozen youtube videos that claim to be for JST but are actually for DuPont connectors which are longer than

I think someone was looking for a source for 2N3053 transistors. A pack of 10 pieces on Amazon is $9.90 with 4.2 star reviews. They are sold by and ship from Amazon. Manufacturer is listed as "Major

About a week ago, I had 5 of those transformers in my cart Alan. When I was ready to order, they only had 3 available to ship. In a way, you helped me. I've been ordering an awful lot from Mouser

Here are the updated schematics and board layout pictures for the multifunction tester. 1. The diode tester has been completely revamped. It now has its own adjustable current source, and a way to set

Hi Dave, I already ordered and received 4 audio transformers, 42TM003-RC from Mouser :) Unless I hear different I am comparing the schematics to the parts list and the schematics has priority. The

Thanks everyone for comments and suggestions. It's a good time to be a home-brewer. 73 de Todd W2TEF

I must admit that I don't pay much attention to parts lists. I tend to work from the schematic, and compile my own list of parts. If I were building a 2N2/40+, I'd start with these schematics (

Hi Todd, I rolled my own already, because ordering 10 boards from JLCPCB is already cheaper than other options. https://oshwlab.com/3ym3ym/RF_prototyping_board Look for the second version of the PCB,

Todd For many of us modular construction goes well, and the modules can be enjoyed in more than one project. And means of construction can be varied. Yes having a practical means to mix SMT and leaded

Ryan, thanks for the quick response and link to video. And thank you for a great proto board with free gerbers! To me it makes a lot of sense as a Manhattan-alternative. Dead bug makes sense.

The W7RLF board is designed to use IC's either dead-bug style, or with the grounds being used to mount the IC to the groundplane only, and the rest of the pins being bent up to float above the board

I've bought a few various PCB's but haven't used any yet. Take a look and you might be pleasantly surprised at the variety and price. Amazon is pretty amazing, we buy virtually everything from my

Jim, I did NOT know about that: thank you. I generally avoid Amazon in my own little one-person Quixote protest. But sometimes one just has to admit they've won and go there! Do you have some

Hey Todd, I'm sure you already know but maybe this will help others. There are a ton of protoboards available on Amazon in various sizes and aspect ratios with a variety of trace patterns. They are

I've watched this group for some months, and remember the hey-day of QRP-L and Manhattan construction when I was first getting into Amateur Radio. Recently re-licensed, I've been building back up my

I downloaded the parts list from Jim K8IQY's web site labeled "2n2_40+_new_piggy.pdf" and at the top of the list it says "revised for 11/23/2003 schematics".

Sorry for the email not working. Lots to do since I took over operations of a broadcast radio station and am contract engineer for seven other radio stations. This cuts into my free time but I'm

Hello Rick, I do not think it is premature to post the FAQ so early.? I think it is a good thing because some of us were worried if the store was closing or something because all the radios
