The question pool did change effective 7/1/94. A pretty significant upgrade, less than 1/2 of the origninal questions were included. If you are interested in the new pool in a Software Study Guide with lot's of features - graphics, explaninations, analysis etc. -- Call QSO Software at 1 800 GUD DX 73 -- 1 800 483 3973. Jeff
The Iambic chips that are typically used in keyers, the Curtis 8044ABM, does have two modes available -- A&B. I can never remember which is which, but one has a self completing feature where as even if you come off of the paddle while a tone is sending, the subsequent dit or dah will still be sent. You must actually be ahead of the sound with your movement. Supposedly this can allow you to reach higher speeds with the paddle. The bigest impact I've seen, is that if you are used to the non-completing mode and try to use the self-completing you have a heck of a time not getting an extra dot or dash at the end of a character. Not a very detailed explaination I realize but I hope it helps. '73 Jeff WB3B
