Repost? Just finished the first one,…the other one is 23 seconds difference… (video #389 - #390)

[@w2aew]

Yes, the previous one had an error at the end where the RF Power is adjusted. This has the corrected snippet (starting around 36:36)

Very well done video, Alan. Thanks for sharing.

[@W1RMD]

Looks like a great little radio! Thanks for doing such a good job describing it. 73!

The correction was something I wondered about yesterday when I saw the first version since Bird wattmeters are only really accurate towards the top end of the scale and then it's something around 5-10% if I recall correctly; if you're looking for a peak that would do down beyond a certain point the relative measurement might be ok, but if it in fact then exceeds the rating of the transistor then it could be problematic...good catch in retrospect, thanks Alan! 73 - Dino KLØS

Nice vid Alan :) To ground the crystals, it may have been neater to create a loop at one end of the wire (around a screw driver say) and solder the loop to the inside edge of all four crystals - then run the other end of the wire to the grounding point. That would save obliterating the crystal markings too.

well done! Looked like a fun build!

[@MobiusHorizons]

Nice video! seems like a well built kit!

Hi Alan, I enjoyed this video. I wonder if we have a budding Ten Tec or Elecraft company in the making?

Another good tutorial, thanks for posting -- 73 Lou KT1R

@W2aew - Reminds me of Heathkit... *sigh*...The memories. 😌

কেমন আছেন বড় ভাই আপনার ভিডিও মোটামুটি অসেক ভালো লেগেছে। আমার অনেক বড় শখ যেটা আমিও আপনার মতো একজন ইন্জিনিয়ার হতে চাই। আপনি যেভাবে মেশিন ব্যবহার করেন, যেভাবে মাপামাপি করে কাজ করেন এটা আমি অন্য কোথাও খুব কম দেখেছি।এখন আপনি যদি আপনার ব্যস্ততার মাঝেও একটু সময় করে আমাকে এই ইন্জিনিয়ারিং পড়ার জন্য কিছু দিকনির্দেশনা দেন তাহলে আমি আপনার কাছে কৃতজ্ঞ থাকবো।এই বিষয়ে প্রাতিষ্ঠানিক ভাবে কোনো শিক্ষা আমি অর্যন করতে পারিনি। এবং বর্তমানে আশা ও শখ পূরণের জন্য পড়ালেখা নিয়ে খুবই চিন্তিত আছি সুতরাং আমি এখানে পিছিয়ে আছি। আমি চাই একদম আপনার মতোই দক্ষ হতে। আপনি দয়া করে এই বিষয়ে একটি রোডম্যাপ দিয়ে একটু সহায়তা করুন। যেমন প্রাথমিক ভাবে কি কি বই পড়তে হবে কি কি জরুরী তার পর কি, তারপর কি এভাবে। please brother.

There are no shortcuts to learning. One of the first books I always recommend is "The Art of Electronics" by Horowitz & Hill. This is a great book with a lot of very practical information, without being very heavy on math. The other recommendation is to build, experiment, fail & fix, etc. as much as you can. There is no substitute for experience. You learn a lot more from your failures than you do from your successes.

"First of all, I deeply respect you for responding to my call. Sir, I am a citizen of Bangladesh, and my home is in Barishal. My language is Bengali, and these words are translated using AI. I actually don’t want to learn briefly. I want to be like you. What else will be needed along with this book? And is this suitable for the first step?"

[@w2aew]

@@abubokorsiddiq580 Everyone has a different journey. My journey included: starting with electronics as a hobby when I was a teenager, getting my amateur radio license when in high school, going to college for my BSEE bachelors degree in Electrical Engineering and working for 39 years in electronics, fiber optics and currently in Test & Measurement industry. All along includes a lot of reading, experimenting, building, repair and troubleshooting electronics. That book is good step. I didn't have the benefit of things like the internet, youtube, etc. when I was starting out. So, I would imagine that your journey will be quite different from mine.

[@abubokorsiddiq580]

Thank you sir. I hope you will be my side as a suitable guide and support for me.

Usually the PA gate bias voltage is set by seeing the quiescent current through the drain.

[@w2aew]

Jonathan didn't provide a provision for this, but I suppose you could carefully monitor the overall supply current for the change (supposidly due to Drain current), if we knew what the target drain current would be.

Costs too much

[@w2aew]

It’s a little pricey, but I like supporting the individuals like this.
