Fwd: [eu-amsat] HO-68 versus AO-51
by n5uxt＠email.com 26 Apr '10

26 Apr '10

Found this interesting from another mailing list. -----Original Message----- From: John Hackett <archie.hackett(a)hotmail.com> To: eu-amsat(a)yahoogroups.com Sent: Sun, Apr 25, 2010 3:50 pm Subject: [eu-amsat] HO-68 versus AO-51 HO-68 v AO-51 ??. HO-68 versus AO-51 - and the university downlink only satellites - (aka the FM menagerie). In my honest opinion it's a 'no contest' scenario - with HO-68 winning hands down. The two main reasons for me making this claim are ... 1) HO-68's superior orbit. 2) It's multi-mode transponders. On a typical European pass an HO-68 orbit has a footprint the covers from Spain in the west to India in the east, Norway in the north to Sudan in the south ... and all points in between. Whereas AO-51 is FM only ... HO-68 has transponders for CW, SSB as well as FM. HO-68 is (IMHO) easier to operate due to it needing less power to get into the transponders, albeit, to really take advantage of that, a knowledge of CW is required, which *STILL* shows it's great advantage as weak signal mode. When all else fails ... switch to CW. Igor, RW3XL has been operating cross-satellite with HO-68 to VO-52 and HO-68 to AO-7 ... keying the up down buttons for CW since his keyer is on the blink. For those wanting to learn, the 200mW beacon sends *SLOW* morse and it's copyable on a piece of wet string wrapped round a rusty six inch nail. I've proved this over and over on HO-68 at the beginning of passes when the elevation is under 20 degrees and a SSB just can't make it - switch to CW - Q5 copy - (Domenico, I8CVS will endorse that). I believe that HO-68 is becoming the experienced 'operator's' satellite while AO-51 will remain the platform for the potential newcomer ... where they can QRM eachother to their heart's content ... more power Egon ... MORE POWER !!! ... (with due apologies to the Hollywood film 'Frankenstein'). For me at least, HO-68 has brought the fun back into amateur satellite operating, particularly on CW ... akin to RS-10, the most popular satellite ever - (judged by the amount of users) - after the veritable old AO-7. While everyone is entitled to his or her opinion, operating FM on a satellite is about as much fun for me as watching paint dry and is, in my opinion, the worst possible way to introduce a potential newcomer to amateur satellites. My EU-Amsat co-founder, SV1BSX (SK) first used the word 'zoo' to describe the AO-51 standard of operating. There ought to be a sign on the microphone ... PLEASE DON'T FEED THE ANIMALS. 73 John. <la2qaa(a)amsat.org> __._,_.___ Reply to sender | Reply to group | Reply via web post | Start a New Topic Messages in this topic (1) Recent Activity: Visit Your Group Switch to: Text-Only, Daily Digest • Unsubscribe • Terms of Use . __,_._,___

Fine, I have no issue with that. Stop maligning the BOD though. Try something productive if you want to help AMSAT, HEOs, or linear transponders. 73, Drew KO4MA Evil BOD member

Re: [Moon-net] WX sealed box for Coax Relay
by Dee 26 Apr '10

26 Apr '10

I copied the AMSAT-BB with this as sometimes a hint or kink is passed on to all. You can use an old seaman's type of drain hole hint. If the hole is about 1/4" or so, get a piece of string and put a large knot on one end, pass it through the hole and add another large knot with about an inch or so protruding. As the wind blows, it knocks the string around and assists the draining. I used it in many a situation with tuners and couplers and even in satcom domes. The string acts as a deterrent to things going in and clears the hole when the wind blows. Hope this helps... 73, Dee, NB2F -----Original Message----- From: moon-net-bounces(a)list-serv.davidv.net [mailto:[email protected]] On Behalf Of WB2LLP Sent: Monday, April 26, 2010 3:29 PM To: guenter.koellner(a)mixed-mode.de; JAY Cc: moon-net(a)list-serv.davidv.net Subject: Re: [Moon-net] WX sealed box for Coax Relay Some way must be found to plug the drain holes in such a way that lets the moisture in and out, and keeps the insects out.

Arecibo on Handy
by David Barber 26 Apr '10

26 Apr '10

OK, I know nobody is going to believe this but....on my life... I have been outside with an FT-817 connected via a very short piece of coax to a Diamond A430S10R (small 10 element beam modified for handheld use) and headphones and KP4AO was just audible on SSB. Signals were inconsistent but solid enough to copy their callsign and CQ calls around 19.00UTC and the odd information exchange thereafter. Now they've switched to CW copy is a good 80%. No signal strength showing on S-Meter of course but who cares. I would never have believed it had I not heard it with my own ears. Note: NO preamp was used. David G8OQW JO01FR
