Just tuned in via the Jumonville, PA SDR.  - SIO 454 - Playing Spanish translations of American rock songs.  YL with Spanish-language voice IDs.  It may be worth noting that websites and emails mentioned seem to use "dot com" which I associate with Spanish-speakers who grew up in the US, rather "puntocom" which I associate with Latin-American Spanish.

2105 - OM ID as Radio Humperdoo.  Guess it was a relay.

Another relay of Mix Radio International who's currently on 5125 KHz USB.
SIO 222 on the Westminster, MD Kiwi.  Can't pick it up locally.

1704 - Sign-Off?
1705 - Carrier is back.  There was audio for a second, then back to dead carrier.
1714 - Still on.  Every once in a while I get a little audio, right at the noise level.

From what I’ve read on EEVBlog and reviews on Amazon, the Hantek scopes seem to be coming from the factory “pre-hacked” now.  I’m sure they only guarantee performance for what each model is rated for.  One theory is that they have a tiered Q/A system with the best performing units becoming 200mhz and the worse ones becoming 50-75mhz models.  They all seem to have 200mhz firmware now, but I’m not sure how accurate they are.

First off, thanks for all the great responses!  This community has been one of the most courtious and inclusive I've ever been a part of.

I'm starting to see the benefits of a DSO, and if I can't find a good analog scope for a song, I'll probably end up buying a Siglent or Rigol.

Thanks for the advice on a better soldering station and specific kinds of solder.  I've currently got a Weller WESD51 which has served me well, though I realize it's not something I'd make my living with.

The Nano VNAs are impressive for the price, even if you only use it as an antenna analyzer, which is about all I know how to do on a VNA right now.

Should I be worried about a function generator or spectrum analyzer?  I'm trying not to get overwhelmed learning about every piece of gear until I know I have a use for it.

TLDR: What hobby-level test equipment would you recommend for a first build project, a 100mW medium wave AM transmitter?

Up until now, Iíve just been a user of radios, but never understood at a fundamental level how the parts worked together.  Iíve built crystal receiver kits and arduino-powered robots with the kids, but always following someone elseís instructions.  At present, my troubleshooting ability is mostly limited to making sure I followed directions or a schematic correctly and checking for bad connections/solder joints.  I look at RF circuits with a DC short, and it blows my mind that it works.  But, Iím working on correcting that.

I figure thereís only so much I can learn from reading forum posts and watching YouTube videos.  I want to build something, if not from scratch, then at least with an understanding of why the designer chose the components he did.  My plan is to build several iterations, starting with something super-simple, like using an op-amp to generate a carrier, and modulate it directly with a line-level audio source.  Then Iíd like to improve the design step-by-step to get better quality audio, low-pass filtering, and a usable range with a matched antenna.

Aside from the actual components and tools to assemble them, what am I going to need for this journey?  Iíve got a breadboard, soldering station, multi-meter, etc. as well as the ďend userĒ stuff like a dummy load and SWR meter, but I donít expect to need those until much later.  Iíve been thinking of getting an old analog oscilloscope on eBay or Craigslist since they seem to be available around $50 if youíre patient.  I guess at some point Iíll need to prototype a PCB or order it from China.  Can some of you more experienced guys tell me if thereís something important that Iím missing here?

I realize Iím probably not really giving enough information to get a good answer, but Iíd at least like to get some ideas on what to start thinking about from those who have done it before.

SIO 444 S7 in GA
Don't think this is the same operator that was switching freqs before.  This signal is 3khz wide as opposed to 5khz.

0425 Pink Floyd - Hey You
0427 Pink Floyd - Brain Damage

Nothing locally, but listening on the Westminster, MD Kiwi.  Fading now, SIO 333

1522 Buggles - Video Killed the Radio Star
1527 OM in accented English.  I think he gave out a PO box.
1531 Neil Diamond - Summerlove - Peaking to S7 sometimes now.  SIO 434
1534 OM - did I hear "free radio magazine?
1536 Hot Chocolate - No Doubt About It (needed Google's help on that one)
1540 OM definitely not English this time.  Too weak to make a guess as to what it is.
1543 Pretty sure I heard "PO Box 314" again

S9 in GA.  Really sounded good. SIO 545

0100 caught the end of a song (in Dutch?)
0102 The Show is Over
0105 parody skit

Infrequent fades to S7 and peaks to S9 +10.  On peaks, I could get a decent copy listening to the residual LSB.  Still sounded good during fades.

Nice wide signal as usual.  S7 but not much noise tonight.  SIO 444

0058 B52s - Love Shack
0101 ?
0104 Suspicious Minds

10
Big signal in GA tonight.  SIO 444

0053 Motley Crue - Girls, Girls, Girls
0055 Off-air... Must have just caught the end of the show.

1430 Can hear music at the noise floor, but it's too low for me (or Google Assistant) to identify.  Sounds like Motown

Hearing one half of a conversation.  This frequency is allocated for simplex use on the Mississippi River, but with that small an area, I would expect to hear both sides.

1203 OM - "Yeah, I didn't realize I left mine at home."
1204 OM "No big deal.  I found another one."

14
I'm late to the party.  Sounds great though.  SIO 444.

0032 B52s - Rock Lobster
0037 ID into 80's rock tune
0040 Paul Young - Come back and Stay
Stepped out and missed at least one song
0048 Tom Tom Club - The Genius of Love
0054 dance tune I should recognize, but I don't..
0059 Starting to fade below the noise off and on
Thanks for the show..

Listening via the Westminster, MD KiwiSDR.  Nice wide USB signal at S7 with very little noise.  Unfortunately, I don't have any signal at all for them locally.  Using Shazam to identify the songs, since I'm not familiar with any of them.

1804 Fourplay - Sunnymoon
1807 Concorde - Shadowland
1810 ID - Thank you for tuning in to mix
1810 Atlantis Music Project - Timo&Soia
1814 Google Assistant says: Sorry, I wasn't able to recognize this song.  No prob, Google lady, neither was I.
1817 Dario Carli - New Landscapes (with fades to around S3)
1819 funky synth bass, still can't identify it... Google says it's Menny Fasano - Susan (Love Mix)
1826 Jjos - Fantasy (Terrace Mix)

1830-ish Had to step away from the computer, but it still sounds great playing around the office.  I really enjoyed some of the more upbeat stuff.

1858 ID - Mix - Still going strong.  Signal up to S9 now on the Westminster, MD KiwiSDR.
1858 Night Flyte - Square Root
1901 Chris Standrig - Static in the Attic
1907 ID - Mix Radio International
1907 Chuck Loeb - Happy Hour
