Nick, 2 questions: 1 - The last reading is for 80 meters? 2 - What frequency did you use to test 40meters?? There is an anomaly at a setting of 7.000 HMZ on the frequency that could switch in the

Jerry I'm still confused. Can I plug a USB 2.0 micro cable into a USB 3.0 connector? On-line information on the RP2040 chip is somewhat limited, but implies that it is compatible with code written for

HI, I install the Arduino on my Linux machines (Raspberry Pis) directly from the download provided on the Arduino web site. That download and installer is up to date. I have a RPi 4 and I really like

Hello, I n short I have not welded my capacitors and resistances. I did not know that there were differents models of cms, and so those received were in 0805. Impossible to weld them because the

Hi Again... Just an update on the 'low power' situation... While I wait for the dummy load/power meter kit from QRP Guys, and the buts for my RF probe, I managed to borrow an MFJ Power/SWR meter

Arv, First a quick paragraph for those who don't know an RPi-Zero from an RPi-Pico: Using a Raspberry Pi running linux as a host computer has been done, could work well. In post #86951, WA4THR

If replacing the Arduino with a Raspberry Pi then any of the RSPi versions should be more than fast enough. If using a RsPi as the attached PC for interface with an Arduino the fastest and most memory

I use a 10x stereo inspection microscope for my 'small' soldering jobs.? I've found it very useful! and, quite fascinating to watch as the heat from the soldering iron flows to the pad & component

Jerry, We have both , ILI9341 and Si5351 done. What remains is just the spaghetti code to tie up the things. I will do a release of a trivial implementation soon. Venu, VU2BVA build an adapter for the

Farhan, Agreed, the RPi-pico looks like a wonderful long term choice, for many reasons. But most vendors are out of stock on the RPi-pico, and I'm not seeing anybody selling more than one or two at a

Jerry, I have been playing with the raspberry pico. It is easy to program and understand. The getting started book (pdf) issued with the board us fully of examples that we can easily use. I have

Some of us have more rigs and building opportunities than time, while other folk may rely on the ubitx as their primary rig. The designer is suggesting patience not despair over our passion to acquire

May be time to consider units that contain those "becoming rare" items for cannibalization. If a defunct board/unit had become defunct for another reason but the "rare" items are still good, may be a

Regarding those STM32F processors in the LQFP48 package, if I click "Normally in Stock", it shows 101 results. If I then click "In Stock", it shows 8. No easy answers here. Jerry, KE7ER

I’m in Texas, and a month ago we had a historic winter storm that shut down the whole state for a week. One of the unexpected results was that many petrochemical manufacturers had their plants go

For a processor, could go to an STM32F* in a popular package, placed directly on a new Raduino layout. Lots of alternatives if a particular flavor dries up
