It's time again for another net tonight Thursday the 16 th of April. We have our nets alternating Thursdays on the Mt Beacon repeater 146970 PL 100 and on Echolink (n2eyh-l). We are located about 70 miles north of NYC. Please join us and share your satellite knowledge with the group. 73 Gary WA2AQH **************Great deals on Dell’s most popular laptops – Starting at $479 (http://pr.atwola.com/promoclk/100126575x1220029082x1201385915/aol?redir=htt…)

A couple of years ago, I had an '88 Citroën CX 25DTR turbodiesel, which was so (electrically) quiet I could pick out individual interference sources in cars parked beside me. Mechanically it sounded like a Caterpillar D9, though - not the smoothest diesel I've ever had but then 300lb/ft at 1800rpm with 16psi boost will do that. I had it running electricall silent once, when the main power fuse blew disconnecting everything except the starter motor feed - no electrics at all. All I did was remove the brass slug from the stop solenoid valve, tickle the starter lead (there's a handy plug and socket beside the battery for doing this) and ran about 40 miles with no electrics. Lack of brake lights was a bit scary, but the roads were quiet ;-) Gordon

FCC 70cm Proposal
by Keith N4ZQ 16 Apr '09

16 Apr '09

This is interesting.... N4ZQ FCC Proposes to Allocate 20 MHz of Spectrum in 413-456 MHz Band For Implanted Neuromuscular Devices The FCC has released a Notice of Proposed Rulemaking (NPRM - ET Docket 09-36) seeking comment on a proposal to allocate 20 MHz of spectrum in the 413-457 MHz band for use by wireless medical devices that could be implanted into the human body and used to restore sensation and mobility to paralyzed limbs and organs. The devices would act as a wireless medical micro-power network (MMN) within the patient. Among the conditions that could be treatable using MMNs include polio, ALS (Lou Gehrig's disease), cerebral palsy, and spinal cord injuries. The 400 MHz band is targeted because it is optimal for RF propagation through body tissue. The devices would require at least 5 MHz of bandwidth to function and would operate on a low power, secondary non- interference basis. Twenty MHz of spectrum in four band segments are proposed so that the device would have four options in case one band segment was already in use in a given area. The NPRM seeks comment on the feasibility of four different band segments: * 413-419 MHz * 426-432 MHz * 438-444 MHz * 451-457 MHz Comment is also sought on: * Potential for interference between MMNs and incumbent users * Service rules (licensed or unlicensed, definitions, permissible communications, eligibility, etc.) * Technical rules (power limitations, bandwidth, frequency stability, channelization, antenna locations, etc.) The text of the News Release is available at: http://hraunfoss.fcc.gov/edocs_public/attachmatch/DOC-289482A1.doc ____________________________________________________________ Learning Centers - Click Here. http://thirdpartyoffers.netzero.net/TGL2241/fc/BLSrjpYXVv0gKYPqCr8IkCaCq5KA…

AO-51 2100 UTC pass on 4/15/09

I was listening with my AO-40 S band equipment to the AO-51 2100 UTC pass onApril 15 up the US north east. But heard nothing. Was anybody active? It was a work day and most of the footprint was in the ocean. 73 de WB2LLP Gene

Solid QSO with K4YYL mode L/S, great to know my AO-40 (sobsob) gear is still working! Now, where's that HEO? 73 Bob W7LRD

Hey Jeff, I hear ya. I have a blast with the Elk and my FT-60. Part of the fun for me is figuring out how things work and experimenting. I could buy a M2 antenna and be done with it, but this just keeps the hobby new for me. I worked AO-50 and ISS on my first attempt with the elk long periodic, and man did the big hit me!

Im sorry. I sent my last email prematurely. As i was saying, I did copy W6DXO, EX1ROR, W6RO, AND W7OJ during the last pass of AO-27. It wasnt spectacular copy, but i am still smiling that it worked at all. It had the best receive at nearly 90 degrees. I was hoping to improve my lower angle reception. This will be fantastic when I figure it out. Thanks again to Rick WA4NVM for getting me on the correct bird! Cheers! Steve KI6OQU

Hi Dave, Dont be too suprised. It probably not the antenna, but my construction of it. I am building it and I new to the theory. I wish I had been born with an engineer's mind instead of good looks! I also had not been listening to the correct birds. Thanks to Rick WA4NVM, I did copy some of the AO-27 pass at approx. 3:00pm pacific time. It wasnt great copy, but i heard On Wed, Apr 15, 2009 at 3:01 PM, Dave hartzell <hartzell(a)gmail.com> wrote: > Hi Steve, > > It is surprising to read that you are not hearing anything.
