Re: [Flexradio] Processor Affinity for PowerSDR

2008-03-29 Thread stoskopf
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? N0UU ___ FlexRadio Systems Mailing List FlexRadio@flex-radio.biz

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 of

I gave a talk at CSVHF some years ago on Stochastic Resonance. Strictly prepared from reading about something I found interesting and not from any real experience or knowledge of the subject formally. At the same time, in Vienna happened to meet someone working on speech compression, etc. on the

While I'm getting a round tuit for that...I decided to try some things to decrease the load on the XP. The one thing that really helped was just going from 192K to 96K. It cut the CPU load almost in half. As graduate economics major before I went into medicine: OTOH, (supposed to be a

For hams building their own equipment, there's no real requirement to prevent out of band transmissions by automatic means. Different post Interestingly, hams just have to use good engineering practice, and aren't required to demonstrate compliance, so, while it's nice to have test

From: Joel Harrison [EMAIL PROTECTED] I have about come to the conclusion that my computers just aren't meaty enough to run 192 KHz with the Edirol, as you note. Sadly, Flex-radio says absolutely nothing about minimum system requirements on the web page. This is now the second time I've

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, N0UU

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. N0UU ___ FlexRadio mailing list

I've been a RSGB member since the 70s so that I get first crack at Hawker's TechTopics. If you haven't noticed, RadCom has made a huge format change and is becoming the technical magazine that Ham Radio was. The last few months are more than a quick read. The May 2006 version has a great

Re: [Flexradio] Transverter offset

2005-08-04 Thread Lawrence Stoskopf
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
