Errata in the Part 4 Discrete Audio Amplifier

 
One of the blog readers, W4JED contacted me regarding the "reversed  polarity" of the output capacitor on the discrete component audio amplifier that appeared in Part 4. The schematic error would have most like caused a smoking of the capacitor (or a very loud bang followed by the smoking). Thank you for bringing it to my attention. The corrected schematic is shown below,

  1. Hi Pete,
    I have been working on creating PCBs similar to yours using my homebrew CNC machine.
    I cannot find any software that lets me produce 'etchings' like yours.
    I have put something together using Python to create simple rectangular cells but nothing like what you are doing.
    Can you describe your process? I am sure there are many others similarly interested.

The uBitx is inhaling RF at N6QW

Catch the Wave ~~~ The uBitx is Alive!12/23/2017 ~ On the Air QSO with the uBitx! The uBitx is a real winner --so get off your butt and order one! Listen to the on the air comments and also make the N6QW linear amplifier hack as you will need that during poor band conditions. The fact that you can run a linear amp without hiccups and burps is a testament to the design! Thank you Farhan.

The "Cool Juliano Blue" LCD has to be a factor in how good it sounds! I am also told that the blue display is a major factor in the fight against global warming. OOps forgot there is no global warming or so our leader tells us. Merry Christmas and Happy New Year to All. PS. When you watch the video note that the guy with the FLEX6500 said you sound good and even compared what he spent and what the uBitx costs. The uBitx stands tall with the Big Dogs! Keep in mind my "hack' to add a linear amplifier control. Anymore out here on the left coast when operating on 40 Meters --QRP is some…

Return of the Simpleceiver Plus! 9/12/2017 ~ Arduino Sketch Code for the DCRI have posted the code for the Simpleceiver Plus DCR on my website and you can link to it from here http://www.n6qw.com/Simpleceiver_Plus.html I have also copied the complete blog thread on the Simpleceiver Plus DCR to this page so that there is an easy archive of all of the info that is on this blog. The downside is that it takes a long time to load since it is a huge file. But the plus side in the event we have another ghost in the machine with this blog (like losing the comments) the data will not be lost. This will be the last posting to this thread. The next series will be on the conversion to the SSB transceiver. 73's Pete N6QW My Apologies "The Ghost in the Machine" ate the Comments. I have no idea how that happened or how to get them back.7'3's Pete N6QW 9/08/2017 ~ The Arduino/Si5351/Display Wiring The above is a pictorial wiring diagram since some homebrewer's are new to schematic dr…

Roll Your Own SDR SSB Transceiver N6QW Moves Totally to the Dark Side of the Hobby!11/27/2017 ~ Observations and 1st DX ContactToday I wanted to spend a bit of time comparing the new SDR homebrew transceiver to "filter" type rigs I have built. First though I do want to share that I worked my very 1st DX station with the SDR rig and that was XF1IM who is in lower Baja California. The distance was 1600 miles running 100 watts. So I am beaming from ear to ear. Firstly I do want to acknowledge once again the pioneering work of Charlie, ZL2CTM and his several you tube videos that got me kick started into rolling my own SDR rig. Notwithstanding I do have several SDR kit radios including several Softrocks and the Omnia based on the Peaberry --and even one that uses a Softrock with a Raspberry Pi. So I am not brand new to SDR, but I am new to rolling my own. Above all there seems to be a clarity to the signals and perhaps that is because the bandwidth may be a bit wider. It was even su…
