>>> NO NO on the Rat Shack ones.  I've found the (near) best replacements when compared to the Astatic original is one from Mouser Electronics. Almost the same size and in the crystal variety if memory serves me correctly.  Response charts bout the same also. Fellas help me out with the Mouser info as I can't find mine presently for Bob.  Bob, it's kinda like, if your date says she's sick, shoot, ask her sister to go barn dancing that Saturday night as she'll be close enough. Better that giving up and having to end up watch the cows munch grass during the afternoon and growing overnight. Hey, even in the best of ham radio families the other members will never know. In addendum, Bob, in all my years in ham radio I've never run across a ham who could tell how old my D-104 crystal microphone element was in it's life cycle nor how many actual crystals were housed in it case indicating mv output.  Shoot most of us in our well ham radio seasoned time line nearing end of the paper roll can't even discern our birth given names when supper calls go out indicating it's on the table getting cold.   That's why supper bells on the back or front porch (your bride's choice) that rang out CQ were invented in the first place. <grin>

I am looking for anyone who might have a spare laying around that they would be willing to part with. My next step might be to try and replace it with one of those Radio shack elements that I have read about, but want that as a last resort. Anyone have an opinion on those elements?
