Hi all, I recently swapped for a Grundig yb400 portable communications receiver!  I'd forgotten how good those little units really are!
It's been several years since I'd operated one, and most of the commands came back to me.  But I can't remember how, in the initial set up mode, you set the 9-or-10KHZ step for the MW band.  Apparently the default is 9khz, as when I use the up-down tuning, it tunes in 9khz steps.
Yes, the step button, below the up-down buttons will modify that default for individual tuning operations; and the direct freq entry keypad operation is always successful:  But when using the up-down buttons, unless the incrament is preset to the 10khz option, the 9khz step always defaults.
I don't have access to a manual, even in my packrat Gmail folder!  I've recently learned that Ccrane sold the yb400 series, and made a cassette available for blind users, outlining its' operation.
Questions, 1, do any of you have one of the Grundig yb400 or 400PE units?
2, do you remember the preset instructions for the 9-10KHZ step?
3, might any of you have the cassette from CCrane that I could listen to?
4, since the rod antenna on this one has only three sections, do you know how many sections the antenna is supposed to have, and
5, might any of you have a "parts radio" from which I might obtain one?

Thanks in advance, Danny Dyer, Wb4idu.
