#172760 - YOU would sell a suicide candidate a rope
Responding to: ???'s previous message
something in this exchange makes me wish there was a way to force the Ops to state amateur/amateur wanting to produce/pro small qty/pro large quantity.

I recommended that he try using a crystal oscillator, which it is likely he already had on hand, or, at least, could easily find. You, on the other hand, insisted that he didn't need a crystal oscillator. Well, nobody said he needs a crystal oscillator, but I did say it might make things work better, as this is just an experiment.
you recommend in a way that could get him to go out and buy one
Based on the post I answered based on the OP being an amateur and posted based on minimum outlay (buying a crystal is cheaper than buying an oscillator)

Just what did you think you were contributing by your inane remark that he should use the KEIL baudrate parameter calculator? What did you think you were contributing by your remark that he didn't need a crystal oscillator?
"Just what did you think you were contributing by your inane remark that he should use" a calculation at 11 MHz to figure out the baudrate at 33MHz.

Had you suggested a way in which he could obtain a first-overtone crystal of the frequency he needed, that would have been helpful.
digikey, mouser et al when asked

Do you really believe that telling him he should use a SiLabs MCU would help him get his ATMEL-based circuit to function at the nominally 33 MHz rate?
I did no such thing, that I added a bit of an editorial re EMI should not make the OP cry, that it upset you is no surprise, it seems anything that is not of RE origin does.

You're quite apparently promoting KEIL and SiLabs products, Erik,
The only mention of Keil is their handy baudrate calculator which in no way whatsoever requires use of Keil, but has - whatever the brand I used - saved me time. I have not mentioned SILabs in this thread, if preferring chips with a PLL for high clock speeds to minimize EMI is promoting SILabs I suggest you look up 'promoting' in a dictionary

Your most common response to, "How can I do this?" is, "Why would you want to do that? You should do this instead!" Do you really think that helps an experimenter do what he wants?
YES!!!, but YOU would sell a suicide candidate a rope.
