    Steve, I have found that using a 12" square of 1½" Styrofoam to sort my parts works well. I put strips of cellophane tape across the front to write the part identification on and then push the wire leads into the foam. Nothing runs away to hide until I get it to solder on the board. I have been using the same foam boards for several years and just replace the tape as needed.

    Indeed a 78L05 is a 5v linear voltage regulator. It can't handle much current in the TO92 package so you typically only encounter them in the TO220 package (the package with the heatsink is a TO220)

    Awesome, Steve. Thanks for keeping up the theme, "Cool Hamming On A Budget". Can't believe how expensive some QRP amplifiers are, but this one is a bargain, thanks for keeping QRP Labs in the forefront. K7KS

    OMG TO, You have to ohm-out and or look at a color code cheat sheet for your resistors? Sorry, I did chuckle a bit. $30 is pretty good for this. A perfect companion for my x6100 maybe? I know you will add it to this video series. Staying tuned...

    Great OCD idea to stick them all on paper and label them. I'm gonna have to steal that idea T.O.👍
    It's cheap as chips, hope it works okay with the X6100 or 705 too.🤞🙏

      It will work fine with those radios - as long as you're not running voice modes, its not designed for those.

    Like your organization of the layout. Question-Like when you are reading from the meter on one of the caps (15:19), meter reads 347 but you say and write down 390. How does that add up? Robert KD4YDC ps Like your channel and just subscribed :-)

    • @temporarilyoffline
      @temporarilyoffline  Год назад +1

      Hey Robert! Welcome! Most electronic parts have a tolerance rating, so you'll very rarely (or very expensively) find one that is exact. So if it's 390±10%, then 347 is close enough. On resistors in particular, there is even a tolerance band that indicates what to expect. Coming from a computer programming background, this bugs me, but it is what it is.

    Thank you Steve, I will try to follow along. I am trying to learn how to solder and I am in the process of ordering some soldering kits on amazon, just to learn how to solder without spending too much money. I would love to kit build. Thank You KO4UWU

    • @temporarilyoffline
      @temporarilyoffline  Год назад +1

      The hardest part about soldering is getting the courage to get started. I can honestly say it took me over 20 years from first interest to actually getting a real soldering iron and making something. Very rewarding and now I'm addicted!

    I don't mean to be disrespectful but I think its would be important to point out the $14 shipping charge and the $6 credit card charge. My $19 QRP Labs shop clock cost me over $100 with separate shipping charges for the kit , box, and expidited charges unless you wanted to wait 6 months. I like the product and just ordered another QRP Labs product but don't expect the advertised price to be close to what you will pay when your done. Otherwise, enjoy your brand of you tubes and am enjoying this one.

    • @temporarilyoffline
      @temporarilyoffline  Год назад +1

      Thanks Lance! I usually leave that stuff out because it varies per customer - in my case I picked this amp, case and a qcx mini+case -- all before the world went away. If I told you how much I paid for shipping, you wouldn't believe it.

    What fuses would you recomend for the qcx mini and the 50w pa.

    • @temporarilyoffline
      @temporarilyoffline  Год назад +1

      I'd check the amp draw, I'd guess the qcx mini is less than 2a on TX. I'm. Ot sure about the PA.

    • @brianfields4479
      @brianfields4479 Год назад

      My qcx pa would not produce very much power, eventually found the 50ohm patch leads I got off the internet were actually 75ohm leads, now with good quality 50ohm leads everything works great.
      Just thought you might want to pass that on to another person, who might find themselves in the same predicament.
