I doubt if I could have done any better with a $3,000+ radio.
If you want more bells, whistles, buttons and knobs to fit your needs, have at it...spend the money
. Icom, Yaesu, Kenwood, Elecraft, Flex (sorry Stan), etc...they're all good.
Hey Bob, YES you could have done better with a 101MP. I too did CQWWCW last weekend and experienced many many times when I could not have made a Q with a lesser radio, The Africa Q's come to mind, the pile was fierce on them and I worked them all with 100 watts, the big issue was hearing the Africa stations thru all the stupid USA ops calling right on top of them over and over and over with their call letters. It took a really good RX to pull the Africans thru that mess but the 101mp was up to it, especially with the VC tune. No doubt those African Q's would not be in my logbook without the 101MP..
I did the contest this year sans Big AL and legal limit. I did the low power category specifically because I wanted to see how the barefoot 101MP would compete. The majority of my Q's were on 15 mtr (LP Beam) and 40mtr (monoband Vertical)....
As you said, all radios are good but I say some radios are Gooder than others.

Hi Stan,
Of course your 101MP is *gooder* than my 7300

. It better be for an additional $3,200. But I did use the word "doubt". How much better? Let me clarify:
No matter what radio you have, in a pile-up (that's not working split), with perhaps hundreds of stations virtually zero-beat and louder than the DX, you're not gonna hear him until they all shut up. Will you agree with me on that? Busting the pile-up is determined by timing your call, tuning a little off his frequency so he hears a different tone, having enough power for him to hear you in the first place, propagation, and some luck. In other words, mostly operating skill, which I'm sure you have an abundance of. The 7300's DSP filtering can go as low as 50hZ. All the other receiver performance specs are pretty high up on Sherwood's list, for all intensive purposes. But not as good as the 101MP.
Perhaps I could have wrangled some extra Q's by manipulating the various controls on a 101MP, but how much more to make a real difference in my score? Which was 800 Q's (95% S&P) in 27 hours for 553,000 points, using a ground-mounted screwdriver antenna. I could have done more if I was a better operator. But competing against stations with tons more directional/gain aluminum in the air requires a lot of compromise, even with a KW. Trying to keep up my rate, I don't get into pileups (except to JA and Oceania...strangely real strong into those areas), and I'll go back to them later when they're begging for Q's to pick up the mult. And operating from the propagation wasteland of Arizona, I have to wait my turn to get through the midwest and east coast curtain to Europe and Africa. But I did get plenty of them in my log
What I'm trying to say is I don't have two receivers (although I have another 7300), can't put the screen up on an external monitor, don't have "VC Tune", don't have more antenna outputs or I/O options, no 3D panadapter, 1/3 the number of buttons and knobs, 1/2 the size, etc, etc. But the little 7300 gets the job done to my satisfaction.
I have spoken

73 and stay safe,
