I have TI SN74CB3253CDR chip in my Softrock Lite + Xtall 8.3. I guess I need one Fairchild chip. I bought 25 of the TI chips from Mouser to play with :-) That's OK they're pretty inexpensive and I can play below 20m. Thanks for your replacement on the 8.3 :-)
I tried to email you off list but it returned the message. Sorry for having to send this to the group :-) It's been one of those days :-) Regards, John kb9yig wrote: > > Good Afternoon All, > > A problem identified by Bodo, DJ9CS, and confirmed by Mike Collins > requires a change in the QSD/QSE switches recently shipped with > SoftRock kits.
