[GreenKeys] M28 ASR Print Issue

[W2HX]

Hi all,

For the last several years, I've noticed that my ASR does not print traffic the same as my KSR both are on the same loop. I would say the accuracy of the print is much worse than the KSR. But since I had the KSR working well, I never had the impetus to look into in detail. Tonight, I did a simple test and saw some interesting results.

First, I am using a character generator which seems to work well (see attached picture).  The character generator has several modes, QBF (sentence) is one mode, then you can set up two individual characters and send an alternating series of these characters. It also has a "dot cycle" mode, which I believe is simply alternating mark and space.

When I set up R and Y and send them out, both printers work perfectly. However, when I use the DOT CYCLE mode, the KSR again works FB, but the ASR shows RYYRYYRYY. Below are links to the print copy. Note there are two "paragraphs" on the page. The top paragraph is using the individual R and Y characters set up using toggle switches. The second paragraph shows the results of the DOT CYCLE mode. Again, these are on the same current loop.

Anyone have any suggestions where to look?
Thanks
