I've been toying with making some comparisons between the MARK-V and the
PRO. I'll get better at this, but thought this was mildly interesting.
Both the PRO and MARK on a T-splitter to the yagi. Both radios on straight
500 Hz filter. NO APF or anything else applied. I noticed that neither was
perfect print in the Rttyrite windows. They were tuned with the AFC on so
that the yellow lines were aligned, then the AFC was turned off. Then I
turned to the PRO to try the twin peak filters or narrowing the filters etc,
when I noticed PERFECT PRINT on the PRO's main display! I captured the two
radios in the Rttyrite windows with a screenshot - see
http://www.qsl.net/wa9als/print.gif (PRO is left, and MARK is right) If
you're not familiar with Rttyrite, the most recent text is above the red
line.
Then I tried to snap a photo of the PRO's display, but my hands weren't
steady enough for the several second exposure, even at ASA1600! However,
despite the poor photo, you can appreciate the perfect print!

This is not meant to slam Rttyrite in any way. Wide band decode might have
helped, narrowing the filters might have helped etc. I was just a little
surprised by the print in the PRO's decoder!
