Without learning the basics, buying a Rohde & Schwarz CMA180 Radio Test Set is a huge waste of money. It would be more prudent to master a Cobra 138 on your old test equipment before trying to upgrade to more sophisticated equipment with specs beyond your capabilities.
Higher spec equipment does not compensate for lack of skill. Quite the opposite, actually. In fact it's capable of producing a signal much weaker than you will ever hope to detect in any of your customers receivers due to your inability to tune them, plus It creates a learning curve in how to conceal distortion from unsuspecting customers who don't have a clue. I don't expect many videos until he figures out how to hide the bad stuff. Perhaps learning how to follow a service manual verbatim would be a step in the right direction. Mikes Romper Room CB Radio Repair and alignment Shop. There's no such thing as "a little bit of distortion". Any amount of distortion is always a bad thing. If they can't eliminate the distortion, how can they justify charging you money? A big red flag would be when "Captain Splatterwatt" blames a microphone for producing sounds the radio is incapable of reproducing instead of accepting responsibility for his inability to tune the transmitter. Don't drink the Kool Aid!
Beware of shysters who make videos to protect themselves from a PayPal dispute but keep the video private because they don't want the public to see how their skills are truly lacking. If they can't tune a simple single final AM radio, how could you possibly expect them to tune a more complicated sideband export radio with multiple nonlinear stages, ie: a buffer a pre driver and a driver and dual finals? That's a lot of stages. If all of those stages aren't perfectly linear, and if the final two transistors aren't a matched pair, you will have distortion and a splatterbox as demonstrated here:

If they try to tell you some sort of cop out excuse like "everyone's voice is different and one microphone might work better than another microphone with your particular voice" then they are either clueless or a con artist. For example a Neumann U-87 sounds great with anyone's voice regardless of the pitch or tone of that voice. When you plug that microphone into misaligned equipment then all bets are off if that equipment has any Distortion in it. Anyone with integrity would never blame the microphone.
If anyone tries to tell you that linearity and matched components are snake oil, they are either Clueless or a con artist.
If anyone tries to tell you Distortion doesn't matter or that Distortion can be a good thing, they are either clueless or a con artist.
If they tell you the laws of physics don't apply at 27 mhz they are either clueless or a con artist.
Watch out for con artists. They can often be spotted when they label the people who expose them as con artists as being con artists themselves. This is called projection. It's a typical sociopathic/narcissistic tactic when they project their own guilt or limitations upon others to avoid accepting responsibility for their own guilt or limitations.

Some folks should stick to recapping old radios, replacing meter lights, and leave the tuning for someone with a real bench. Simply purchasing a Rohde & Schwarz CMA180 Radio Test Set doesn't make it a real bench. If the components are not configured for the proper test frequency, all measurements will be slightly off and all adjustments will be off in direct proportion to the lack of accuracy of those measurements.
If you never hear them or any of their customers in DX, yet they make grandiose claims of being some sort of "guru" or "teacher" that should be a huge red flag. The airwaves don't lie, but people do. Use a little common sense and pay attention to the airwaves. If you never hear them or their customers over the airwaves, why would you let them inside your radio without knowing how it will perform in the real world? Even worse, if every radio you heard that was "tuned" by this person sounded muddy and faded out quickly, or was incapable of hearing you at a distance greater than 5 miles due to extreme amounts of noise in their misaligned receiver, why throw your money away only to be disappointed a third or fourth time? As the saying goes:
"Fool me once, shame on you; fool me twice, shame on me"
