So we are better off with a fast, single processor CPU than a bit slower
multiple one for the SDR apps if we are going to limit to one?

I saw Ray Petit demonstrate CCW at one of the Washington State Hamfests
about 1971. Was on the mailing list and built one of the keyers, but due
to startup medical practice demands, never got on the air before interest
went away. Ray is gone now, but I discussed with him at Dayton one year

Thanks to Bob, Ken, Al, and Bill for the words of wisdom in setting up the
new computer. Wiped all SDR stuff from the hard drive: Downloaded .Net 1
and 2 and the Service packs for each: Downloaded asio and ran: Set up
the SDR-1000 SVN and ran it. Worked. Then set up the HPSDR version and

Be sure to archive the discussion for us lurkers. I suspect that Linux
will be more and more important for both Flex and the HPSDR groups in the
future as Vista slows the whole system and XP becomes unsupported. Some
"sporterized" OS would really be of future value. Thanks,

1.1 SWR to 1 GHz or so at about a watt. Probably great for 2M IF

Go to www.hpshopping.com and check out QS-265E. Only a AMD Sempron and 256
MB memory, but at least something that works with a good OS. A marginal
system and you get a CRT monitor, but you get what you pay for.

I've been a RSGB member since the 70s so that I get first crack at Hawker's

and is becoming the technical magazine that Ham Radio was. The last few
months are more than a quick read.

Pat Hawker in the RSGB journal RadCom TT, Aug issue just arrived, mentions
FlexRadio in a segment entitled (p.76) "Buying Overseas-Caveat Emptor". The

Not sure how Ham Radio Deluxe does it, but you just enter the offset for
whatever frequency you dial to (after setting up the offset bands) and then
whenever you "tune to that frequency, it applies that offset. So you can
use one of the various signal sources to find the error for that band, a
