Hi Tony, Another thought about the blank BPF boards... It would be nice if you could offer a blank board with one of the three types of cores used depending on the target frequency.
In this thread, I also saw your reply to Cecil: "Kit with CMOS Si570, $42 for US/Canada and $43 for DX. FIN1002 is still included in the kit although not used if the kit builder uses the CMOS Si570." Why are you offering the CMOS Si570 only, it seems the LVDS part is only a buck or two more, has significantly better stability (50ppm vs. 20ppm for the CMOS part) and somewhat better phase noise performance (see Mike Collins KF4BQ test results in Files section). After-all the FIN1002 is included in the kit regardless. Does it have something to do with lead-time? Speaking of lead-time. Does the lead-time increase if I buy a SRL+Xv8.3 with the Si570? My last Si570 buy via the KM5H Group-Buy took at least a month (which actually isn't too bad for a group-buy), and your price for the CMOS part is $4 less, probably due to volume pricing. 73's Dave WB4ONA --- In [email protected], "Tony Parks" <[EMAIL PROTECTED]> wrote: > > Hi Dave, > > The latest posting of the v8.3 Lite+Xtall board show the outline of the BPF board on top of the Lite+Xtall board.
