Dave, Something like this will work on PCB wih drill set to shallow depth. I use a 1Hp motor stand drill. https://www.amazon.in/Generic-Diamond-Marble-Ceramic-Drilling/dp/B075LKSWWG Raj

Ash, Thanks for the construction tips. What kind of saw do you use cut squares. A table saw set very low?? Maybe an angle grinder? -- 73 Dave ADOB ( https://www.qrz.com/db/AD0B ) Raduino bracket and

Ken, I confess I have been quite new with the RPi series and had not heard of the 3A+, but it looks interesting, although 3X the price. In my case, my son gave me a Pi-zero "kit" to play with and I

Clark Martin KK6ISP Yet another designated driver on the information super highway. In the same lab I previously mentioned, there was another project, a basic power supply, transformer, bridge

In my High School electronics one of first projects was a one or two tube AM radio. The most fun part of the class was being there as students finally powered their weeks of works up, and just waiting

The goal is not 'just' an operational radio, it is also about demonstrating the design and build processes (as I read it). From their website homepage: Educational Value Added This is meant to be an

I prefer al-fresco Manhattan construction...... presenting the Furlough 2040 - based on Pete Juliano's Simple SSB...? not so elegant looking - but a thing of beauty for me! I'm working with a Maker

Jerry Wow half hour, those of us who did previous versions may be groaning. Yes there is no button for fast tuning, hence this feature. You might miss it when its gone, or you may wish to slow it

The doorbell just rang. It was a DHL courier with the UBITX. I just put it together. Calling it a "kit" is IMHO a little overblown. It was all of a half hour effort to bolt everything together. The

Yes. (3) Exhibit no amplification (0 dB gain) between 26 MHz and 28 MHz. Vince - K8ZW.

Didn't say it would work for RF, only that it looked cool. Given all of the LEDs in the photo, it's probably not doing anything at RF. Al and I have fabricated PCB's using the same ground plane/etched

The trouble with neat looking circuits is that they are invariably trouble at RF. In Manhattan construction, the pads for inadvertent capacitors of really poor quality that degrade the rf performance

I purchased the uBitx v6 kit and want to upgrade the case and display to the amateurradiokits.in Universal Case Black For uBitx Nextion Display Fitting 5 Inch I have looked over the case and the pics

There used to be a rule that commercial linears could not work on 10M - companies would make them topping out at 15M, and offer a kit to get 10M to licensed amateurs. Is that still in place? - Jerry

Further, it refers to the input of the amp to the output of the amp, not the internal stage(s). Many LDMOS amps I've seen have an attenuator on the input port inside the amp. The 15db factor comes

Vic, Don't forget the "in-between" Raspberry Pi that sits between the tiny Pi Zero and the full-size Pi 3 and 4 - the Model 3A+ RPi. It has a quad-core processor but lacks the RJ-45 and several of the

Actually, I find that pretty cool!! Jack, W8TEE

It does have a nice Faraday cage for shielding. Jerry, KE7ER

Maybe we should stare constructing like this. (below) Also can't wait to see the papers the students in the workshop produced. Like papers of page after page of pure calculus describing the uBitx in
