They approach square/parallel at the equator, but they are always going to have only the two sides defined by latitude lines parallel (what's that, a rhombus?). And at the pole the north and southmost squares are actually triangles, no? So I would say if you are standing at the pole, unless you have infinitely small feet and can really stand exactly on the pole, the number of grid squares you are in depends on how wide your feet are and how far apart they are when you are standing :-) Fun questions!

Etching a KLM RHCP/LHCP PCB
by WILLIAMS MICHAEL 08 Nov '11

08 Nov '11

I've completed and etched one side#1 of the PCB with Press and Peel. Side#2 needs to be etched. the artwork is very basic and can be completed by hand and Rub-On Etch Resist. I had to drill 8 alignment holes to help line up the artwork to each side. Question #1: I don't want the etching solution to leach through the holes. I had some donuts to cover the holes, but they are so old that the glue is no good. Is there anything that can temporarily fill or cover the holes until side #2 is completed? Question #2: Has anyone used clear packing tape to cover the areas where the copper is to be protected or will the etching solution just eat it up with the copper? You have to admit this isn't a typical AMSAT-BB question. In projects before this, I just used side #2 as the ground plane. 73, Mike (K9QHO)

ESA lunar probe

http://www.bbc.co.uk/news/science-environment-15574653 to bad there cant be an amateur radio payload even a really small one...this probe should be "longer lived" then most as it should have a constant energy source... Wonder why the Europeans are thinking of sending Phase 5A to Mars? It will probably never fly and almost no hams can be a part of that...so well why not send it to L2 in the Earth Moon systems...a halo orbit... Robert G. Oler WB5MZO Life Member AMSAT ARRL NARS

Kenwood TR9500
by John Geiger 08 Nov '11

Has anyone used a Kenwood TR9500 70cm all mode on the satellites? I have found one for sale at a decent price, and am wondering how it would do in a satellite station-coupled with an Icom 706 original. 73s John AA5JG

Any ECHO can be received???
by Luc Leblanc 08 Nov '11

08 Nov '11

With so many High power radio telescope bombarding this tiny 2005 YU55 is it possible to hear something from IT? as an Echo! It was probably the dooms day event forecast for 2012 who used to be a bit earlier than expected... it is not what each of us hope to happen or who expect for the/our ultimate end? Is 2005 YU55 will be maintaining a steady orbital path for his next turn around? Curious no one forecast this event? http://www.radio-canada.ca/nouvelles/science/2011/11/07/002-asteroide-terre… "-" Luc Leblanc VE2DWE Skype VE2DWE HTTP://www.qsl.net/ve2dwe DSTAR urcall VE2DWE WAC BASIC CW PHONE SATELLITE

There would be 360 degrees of longitude there, and each grid square is 2 degrees wide. 73s John AA5JG On Mon, Nov 7, 2011 at 2:19 PM, Wyatt Dirks <wyattdirks(a)msn.com> wrote: > thats what i thought but try and find some proof other then manually > doing the math > > ------------------------------ > Date: Mon, 7 Nov 2011 14:16:28 -0600 > Subject: Re: [amsat-bb] Trivia Question > From: aa5jg(a)fidmail.com > To: wyattdirks(a)msn.com > CC: amsat-bb(a)amsat.org > > 180 > > > > On Mon, Nov 7, 2011 at 2:14 PM, Wyatt Dirks <wyattdirks(a)msn.com> wrote: > > > If you on standing on the north/south pole how many grid squares are you > in? > > 73 Wyatt AC0RA > > > > _______________________________________________ > Sent via AMSAT-BB(a)amsat.org.
