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

Re; SST transceivers, for those considering a homebrew version: For my 20m SST, I made several worthwhile mods: 1. I added a JFET amplifier after the crystal filter feeding into the '603 product

Looks like a W1AW-specific version of the venerable "Neophyte." Should be fun! --Kirk, NT0Z My book, "Stealth Amateur Radio," is now available from www.stealthamateur.com and on the Amazon Kindle

Daniel The output power depends upon bias voltage and the impedance presented to the output of the final. If this transistor directly feeds the low pass filter, at 12-13 volt bias it will provide 1.5

I finally searched for Dave AA7EE blog site and yeah, wow - that is a beauty. https://aa7ee.wordpress.com/2016/09/09/a-scratch-build-of-n6kr-and-wilderness-radios-sst-for-20m/ Dave has a link to

Werd! Your boards look inventive! When I latched onto DipTrace* my desire to do Manhattan evaporated! From then on, it was look for projects, design, inspect, submit orders, wait, rinse & repeat. The

Edit.. sorry, I forgot the image. William, Here is mine I made with Kicad and made at JLCPCB. ?This was maybe 3 years ago, cheap shipping was higher then. Cost about $6 shipped for the 5 boards. 40

Daniel All is well. Looking forward to you building an SST or something to your liking. Examine AA7EE projects for inspiration, I recall he describes all the details. If you build a modern SST I

Daniel - There are cheap unauthorized knock-offs of QRPGuys' designs on eBay. That is probably what you are seeing, unless you're seeing ads for people selling their genuine gear from QRPGuys. It's

Gary, Below is a board I ordered after a tutorial by Jim Kortge re the panelizing and scoring. Occurred about a year ago. In the PCB below, the math works out to? $4 additional for the scoring as an
