by Norman W Osborne 11 May '09

Hello to All, Looking for suggestions for feed lines to my preamps, could I use RG213-U ? I am thinking this should be ok as both lines will be only about 10ft in length. >From the preamps, I am using hard line. I also have a UEK3000 receive converter for 2.4 , for feedline, could I get away with RG6, same cable used for sat TV. the run will about 80 ft.... Getting setup for future HEO.s Any suggestion greatly appreciated and many thanks in advance. Norman

Mine is from an Ebay auction, I think the seller has "KAWA" in their name. It works great. 73, Drew KO4MA -----Original Message----- >From: ANTHONY JAPHA <tjjapha(a)earthlink.net> >Sent: May 11, 2009 6:57 PM >To: amsat-bb(a)amsat.org >Subject: [amsat-bb] satpc32 > >Where should I go to buy the cable (CT-62) for the FT-817 that connects the CAT jack to the computer (RS-232 probably) for rig control?

G-5500 Rotor trouble resolved.
by N1HOQ 11 May '09

11 May '09

Hello group. The problem with the rotor has been fixed. Turns out the gears inside had frozen on their shafts. A little penetrant and easy persuasion got things running smoothly again. No parts, just time. This rotor sees intermittent use as its attached to my portable rig, and must sit outdoors.There was a little bit of water in the bottom of the case, as the drain hole was gummed up a bit. I filed it out a bit and regreased everything and she works like a charm again. Thanks to all for the replies and the help. 73 de Shawn - N1HOQ # 33948

Where should I go to buy the cable (CT-62) for the FT-817 that connects the CAT jack to the computer (RS-232 probably) for rig control? Anyone know of a cable that has a built-in serial to USB converter? That would make portable use easier. Tnx and 73, Tony, N2UN

D-Star cubesat
by g0mrf＠aol.com 11 May '09

11 May '09

Following the small satellite developers workshop in April there are a number of interesting papers available online. A cubesat using D-Star which has been selected for launch on the Vega launcher is certainly an eye catching project. http://atl.calpoly.edu/~bklofas/Presentations/DevelopersWorkshop2009/5_Miss… Personally, my favourite so far is the 1U propulsion system capable of propelling a 3U cubesat with a delta V of 400 metres per second. ( This is enough to go from 600km to about 1900km altitude !) Have fun reading... David? G0MRF ________________________________________________________________________ AOL Email goes Mobile!

Kenwood TS-790 w/ 1.2ghz and IF-232 for sell
by R. Chastain 11 May '09

11 May '09

Hi all, I'm selling my Kenwood TS-790 with 1.2ghz, voice module, matching SP-31 external speaker, and (NIB) IF-232 computer module. I'm basically selling most of my gear due to failing health. The TS-790 is one of the best VHF/UHF radio's ever made and will pull those weak signals out that others won't. If you check the reviews for this radio you will see what I'm talking about. CTCSS/PL encode is built in so getting into tone activated systems is a snap. The radio does not have PL decoder modules but those are still available through 3rd party makers. I have the original box for the radio but I'm not sure if I have the speaker box. I do have the manual but it's a bit dog eared from use. Sorry, but I will not seperate the package. Cosmetically, I would rate the radio an 8+ on a scale of 10 only because of a very small scratch on the far right side of the display. If you didn't know it was there you wouldn't know it. It's that small and light. hi hi Also the plastic carrying handle on the side has been romoved by a previous owner. The screws are still there but the handle has been removed. Electrically, the radio is a 10. NO problems whatsoever. Will sell all for $1400.00 plus shipping. Thanks for looking, RoD
