Don’t forget this article from February. http://www.arrl.org/news/ve7dxw-s-rf-seismograph-may-be-real-seismograph

Ralph,

Thanks for the article.  I have never heard of this before, but I see how it is possible with shearing strata of rocks and piezo electric effects.

It is disconcerting when anything interrupts HF radio, especially during major earthquakes (and I assume aftershocks).  I printed out the article in Scientific American and will read it later.

This came to me from my old ARC in Hayward, CA.

Very interesting.  I have never heard of this before.
I doubt it affected line of sight radio, I think it would be hard to Raf disrupt a repeater, as long as it has ax power and the antenna isn't laying on the ground.

Perhaps for our 120 mile links need more power?  Say a kw?  For 40 perhaps a hillbilly beam.  IE three vertical antennas space out to make a beam, pointed to where we need to get to.

Thanks for sharing this.  This week I have been watching some yutubes about the Apollo project and I was in awe of how good the equipment looked.  The amount of testing (and retesting) performed on every aspect of the project is amazing.  For example, a problem discovered prior to any Saturn V launches was a "Pogo" phenomenon where the rockets would oscillate in thrust and slosh the fuel and oxidizer up and down, violently.  This cycle of more fuel, less fuel caused the thrust to increase and decrease.  The "Pogo" was addressed and fixes made to help insure the smooth fuel/oxidizer flow.  They thought the problem was solved.  During the launch of the first full mock-up of Saturn V, during the burn of the first stage, the problem appeared again and when the second stage was supposed to kick in, it failed and the rocket crashed and burned.  After the crash, parts were inspected, and it was discovered that the "Pogo" was so severe that it damaged the second stage rocket nozzles, rendering them unusable, and would have killed the astronauts, if any would have been on board.

The "Landing Module" descent that you shared with all of us also demonstrates the depth of human backup; there seemed to be a human monitoring every sensor on the spacecraft.  You can here this chatter (on the right side of the screen) where monitors are calling out telemetry data almost real-time, as the astronauts are performing tasks.  This deep field of other engineers (monitoring and calculating solutions to problems) no doubt was the reason that NASA could save Apollo 13.

NASA started out trailing the Russians, but won the race to the moon with slow, steady effort that valued human life.

Re: Inventory/ Technical Committee

James Whitehill
 

I agree with Gary about not making the equipment list public.  I'm not sure also about placing it in the CMRA group website.  Maybe I'm old-fashioned, but why not have the executive committee members hold the list in a way CMRA members can receive a paper or email copy?  Paper copies could be distributed to members in attendance at one or two of the Tuesday nite club meetings each year.  That would keep active members informed and allow for timely updates.

I don't any longer have a copy of that email, so if you need me to detail all that again, please let me know.  Also, to say again, it's not a problem where it is, nobody needs to do anything about it, just want to make sure it's on the list.

I'll take it if nobody else has spoken first.  I have an identical radio in use for many years.  Several years ago an identical one went belly up and by good fortune another became available almost immediately, so if you sell me this one it will be my 4th.  Yep, I love it, good to have a healthy backup.  I presume it come with the Kenwood power supply ?

I have a radio I bought from Don a few years back I would like to sell (See attached pic's).   It is just a little too complicated for me.   I have never made a contact with it, but have listen a lot with it.   I also had it on a antenna at field day and with some help it seem to be transmitting.

 It has a built in antenna tuner and I have the manual.   It did not come with a mic, so there is a new one on unit.

I would like to $200 for this since that is what I paid.

Hi Hank, 

The easiest way to find them is probably using your favorite DX Cluster / Spot list.  If you don't already have a favorite, try this one:  http://www.dxsummit.fi

I pulled up their spot list and see several of the 13 Colonies stations listed in the just past few minutes.  Here are a couple of examples from just a few minutes ago.

14265.0 K2M
14033.0 K2J
