[Flexradio] Brickle/AB2KT and Carnegie Hall
On December 22 at Carnegie Hall, the New Jersey Composer's Guild will present Answer to Job, An Alternative Holiday Concert.Frank Brickle (AB2KT) is the secretary of the Composer's Guild of New Jersey. He has composed an opera which will be performed during this concert: http://www.williamanderson.us/index_body.html Frank's opera is a Townley Mystery Play. Mystery plays or miracle plays are medieval religious dramas based on stories from the Bible. Mystery plays were performed around the time of church festivals, reaching their height in Europe during the 15th and 16th Centuries. A whole cycle running from the Creation to the Last Judgment was performed in separate scenes on mobile wagons by various town guilds. Four English cycles survive: Coventry, Wakefield (or Townley), Chester and York. They were intended for the common person. In many cases, it was the only way people could hear the stories of the Bible in their common tongue, rather than in Latin. Frank's composition, The Creation of the World will be performed during this concert. The tickets are not yet on sale, but you may visit the Carnegie site and soon enough the Buy Tickets button will open. http://www.carnegiehall.org/article/box_office/events/evt_7356.html?selecteddate=1005 Frank is a member of the American Radio Relay League SDR Working Group, a GnuRadio enthusiast, contributor to the ARRL/HSMM/SDRWG OFDM modem project, AMSAT member and a member of the Eagle/Phase 3 Express Software Defined Transponder and CC Rider Team for Eagle, coauthor of the DttSP Software Defined Radio package (the SDR core for the Flex Radio SDR-1000), and recently retired from IDA's Center for Communications Research in Princeton, NJ. He did not stop working on technical problems to return exclusively to music as he is a regular consultant to Isigtech, Inc., has recently consulted for CNS Systems, Inc., and has consulted for many large firms including Agilent. The work he did for IDA CCR earned him a very prestigious award from the U.S. government (the Anne Z. Caracristi award) in 2000. He has consulted with many other firms in matters related to signal processing problems which need statistical detection or classification algorithms. Frank has demonstrated a flair and genius for this type of signal processing problem.Frank is the author of an interesting article in QEX Nov/Dec. 2003, Automatic Signal Classification for Software Defined Radios. This was the first article published in the growing area of cognitively defined radio with a view to amateur radio applications but not limited to amateur radio. A Princeton University alumnus, he studied under one of the most influential American composer's: Milton Babbitt. Under Babbitt's tutelage, he earned his Ph. D in musical composition.Frank was recently an organizer of a festival of music celebrating the life and work of the composer George Antheil: http://www.paristransatlantic.com/festival/index.html As an interesting aside, Antheil and actress Hedy Lamarr are credited with creating frequency hopping spread spectrum for use in torpedo guidance systems during world war II and were granted a patent. One could easily understand why Frank would find a kindred spirit in Antheil. To listen to some of Frank's compositions, one need only use Google. I suggest you search for Brickle Merlin. You will find an mp3 of one of his compositions that will stream. The best word I can think of to describe Frank without listing more achievements or writing an unauthorized biography is polymath. http://en.wikipedia.org/wiki/Polymath It seems appropriate as you can see from this list of recent achievements,interests, and his educational achievements. The word is inadequate, but is a useful beginning place to explore this talented and complex man. It is the best my limited command of language will allow me here. Please join me in celebrating my best friend's achievement and I hope you will enjoy the NJ Composer's Guild offering in Carnegie Hall in December. Bravo Frank! Cheers!

Re: [Flexradio] PowerSDR Beta v1.4.5 Preview 4 has been released.
Eric, So far I have found two problemswith 1.4.5p4. 1 The image calibration comes up with "Error Calculating Image Null. Please try again". It does calibate manually by moving the sliders (I use a local broadcast station on 1.48 MHZ for calibration, works fine on 1.4.5.3). 2. When going to SSB TX (Using MOX) the transmit modeworks fine but on returning to RX there is no audio. If the AF control on the front panel is a differentsetting on RX and TX, it works fine. Whenboth the settings of the AF control are the same it gives no audio upon returning to RX. Everything else seems ok at this time. ( 3 board stack, No RFE, using Santa Cruz ) Jerry WK0J

Re: [Flexradio] CAT CONTROL CHECK BOX P3 P4
I've always thought that using a RPM calculator is a sign of a great mind. :-P I still have all my HP calculators in like new condition, except the case of my 15C it's taken a beating but the calculator itself is in mint shape. No worn out keys, they sure don't build them like that anymore. The batteries died recently, this morning I'm running errands and will be looking for replacement batteries, I hope I can find them. I'm so used to RPN that I really slow down if I have to use a regular calculator, I keep looking for the enter key My HP-41C has the all the accessories and tapes, all in mint condition, maybe in 10 years I'll put them up on EBay.

Re: [Flexradio] CAT CONTROL CHECK BOX P3 P4
I'd like to second Phil's comment on Bob's story WOW! When TI introduced the Datamath 4 banger I bought one via a friend that worked at TI at half of retail price, but as I remember that was still quite pricy. After buying one more TI, I've owned nothing but H-P's. When I was taking my Extra exam, (using my H-P 11C) I paused to think that the first time I worked those reactance, and resonance equations and did polar - rectangular conversions, I was doing them with a slip stick, trig tables, and log tables. Sure was easier to push just a couple of buttons. Hand me down my walking cane. Bill Philip M. Lanese [EMAIL PROTECTED] 11/05/05 01:11PM Two very nice posts Bob.

At 01:59 PM 11/5/2005, Simon Brown (HB9DRV) wrote: RPN is the natural way to think, it's also the way computers work. Reverse Polish *Notation* is just a way to describe (unambiguously) a series of operations without parenthesis. It's true that one can implement it with an ALU that always operates on the end of a stack (which HP calculators do), but it's pretty unusual. I seem to recall that the Burroughs B6700 series did (and it also was directly programmed in a variant of Algol, as well). I think there were a few RISC type computers that used a stack. RPN (aka operator postfix form) is also handy as an intermediate form for compilers after having parsed out all the parenthesis, and is very much beloved of computer scientists for that reason. However, when it comes to building a computer to do things fast, a big set of registers and an ALU that can operate on any of them seems to be a more common approach. The convenience of postfix operators as far as compilers go means that there are a number of processors which make operating on operands in a stack (whether implemented with stackpointer relative addressing, or by having a moving pointer in a register bank). For DSP kinds of applications, where you are doing lots of vector oriented calculations (do a chain of multiply/accumulate operations, as in a FIR filter) or where you are doing things like butterflies in an FFT, a stack is also kind of clunky, because you can spend a lot of time pushing and popping operands. Try writing out the basic complex butterfly used in an FFT in RPN (or Forth). X = A+ W*B Y = A- W*B where everything is complex. You can devise interesting stack ALUs that do things like use operands without consuming them off the stack to make the job easier, but pretty quick, you wind up with something that just looks like a conventional register bank that just happens to be stack relative (your operands start looking like SP+1, SP+3 instead of R1, R3). Once you work with RPN it's more difficult to work with 'standard' calculators. In fact it's much more difficult to create a standard calculator than it is to create RPN, but the basic calculator chips are now so cheap it makes little difference. Jim W6RMK
