@loriemerson I read the Other Networks: Radio Transmitter book! I had some parts lying around, and will order whatever I'm missing in order to complete the circuit. I wanted to ask, though:
What would the effects of using a 22 gauge copper wire for the coil (instead of 24) be? I think the diameter difference is 0.644 mm (22 AWG) vs 0.511 mm (24 AWG).
Would that render the transmitter circuit useless, or maybe just change the frequency range I could play with?
I'm attaching a photo- the lower components are exact matches (100/103 capacitors et al), the right-hand side is an old coil I bought for some other RF-radio-ish circuit, the top contains similar parts, and my 22 AWG wire.

@ccjoel I had to ask @rose_alibi for an answer to your question. she says "it would just change the frequency and make the coil a little stiffer/harder to make. the original circuit that we adapted chose the 24g because it fits so neatly into the metal on a pencil eraser. but it shouldn't cause a major change really."

@ccjoel @rose_alibi but also, more importantly, thank you for reading and wanting to build your own circuit! this makes us both extremely happy

@loriemerson @rose_alibi Amazing- thanks for the quick feedback!
Some AI assistant suggested the same thing, and that it might affect impedance, but I wasn't sure the repercussions for it. Turns out #ai are great for beginner electronics answers.
I'm all over the place hobby-wise (consistency-wise) but I think I can finish off this project quickly. In that regard, I greatly appreciated the short-book format for this busy homeowner/husband/dad. I can't seem to find the time to wear my maker hat as often as I'd like! The little one is already intrigued and wanting to help (breadboard for now).
I'll let you know once I have it ready and working. May be after a full week while I get the parts shipped.

@ccjoel @loriemerson @rose_alibi buy a few of each of the cheap items, to get your junk box started! I must get that post finished. Uh, and the blog site.
Pete Juliano N6QW is a veteran radio builder; if you were intent on building transceivers his article How to Stuff a Junk Box (2011) would be a great start. https://www.n6qw.com/Images/Sudden/How%20To%20Stuff%20A%20Junk%20Box.pdf (PDF)

@vk2tty @loriemerson @rose_alibi lol I have a few junk boxes already alright. The components I shared earlier are 10 years old. I'm waiting on a delivery to get the BJT, the variable capacitors etc and of course they're in bulk. I'll be able to build 1,000,000 radio transmitters in no time MUAHAHAHAHA

@ccjoel @loriemerson @rose_alibi oh, awesome, you’re waaay ahead of me, sorry. If I’d made that LCSC order a month back I’d have enough junk on hand for mischief; aah well. Which varicaps did you get? Any inductors?
