Your wish is about to come true...

Since I was digging in to fix the ARRL 10M mixed mode spot problem identified by NX5M, I decided to tackle this as well. The changes have been made to NA, and verified with by TopTen DXDoubler, but the Array Solutions SO2R should work as well.

One slight issue arises when we try to commonize with the "standard" LPT pinouts used by the other programs. None of them (to the best of my knowledge) support the mono/stereo control from the computer. This seems confirmed when I review the schematic for my DXDoubler. If you're using a DXDoubler you'll need to set Jumper1 and Jumper3 as documented for CT/TR/WL, but Jumper2 will need to be set in the NA position. (This jumper does nothing in the CT/TR/WL position.)

The end result should be a set of jumper positions which will alleviate the need to open the box to switch between programs.

These changes will be in 10.60 which will appear on the web site some time this weekend. I originally planned to do this tonite, but I have to clean up some stuff to get an official release together. I'll post a note here on the reflector when the new version is on the site.

I can imagine this is a sore issue with you, and I can well understand, since you were at the forefront of the SO2R protocol development. Others decided to go a different route and complicate the recipe already established.

will a soon to come version of NA be re-arranged so that I do not have to open up my SO2R box and move jumpers around when switching between my Windows based logging software and my DOS based NA ?
