Good results with verticals
by Thomas McGrane 02 Aug '09

02 Aug '09

Greetings from pat n2oeq This past week, I installed two seperate magnet mount verticals on two 3.5 foot square galvanized steel sheets on the roof. For mode J, I use a two meter 3 db mobile antenna and for 70 cm, I use a new MFJ 19 inch tall dual band magnet mount antenna on a second sheet of steel. The MFJ mag mount 19 inch antenna is 3 db on 70 cm. I get great results on recieve and transmit above 20 degree satellite elevations. I paid 30 dollars for the small MFJ mag mount and 15 dollars each for the steel sheets. I recieve on the short magmount along with an ARR recieve preamp. I was searching for an alternative to beams and an eggbeater and I remembered reading good reports from some operating the satellites mobile so I bought the small vertical and it works quite well. For satellite elevations below 20 degrees I use the old 7 element homebrew yagi canted up at 10 degrees on a cheap radio shack rotator. For matching the homebrew yagi, I used a delta match which looks like a triangle of wires on the driven element and I think it helps with high angle reception on the fixed angle yagi. I purchased the custom made galvanized steel sheets from a local heating and ventilation company. They make great counterpoises for the magmount antennas. Performance all the way up to the zenith is fantastic and rivals the signal strength of the beam. My great surprise was its performance on FO-29, better than I ever had. Both verticals are spaced about 10 feet apart and are connected to a diamond duplexer which is connected to my yaesu 8800 dual band FM rig. pat, n2oeq

Pollux & Castor Telemetery
by Armando Mercado 01 Aug '09

01 Aug '09

Hi, Is there a central depository for ANDE2 telemetry? I have a couple a days worth stored up. Also, I noticed very few frames from Castor. Most telemetery frames posted are from Pollux. Is Castor running less power? Thanks, Armando, N8IGJ

FO29 question
by John Geiger 01 Aug '09

01 Aug '09

I have been off the satellites and the amsat reflector for a little over a year, but put up a dualband yagi yesterday and have already been having a blast getting back on the sats. I am sorry if this question has been covered recently on the reflector. I had a nice QSO today on FO29. I seem to remember that as of last year, FO29 had been declared dead? Am I imagining things, or did it recently come back to life? If so, how long has it been operating again? Glad to see it is back, it has always been one of my favorite satellites. 73s John AA5JG (ex.

Re: ANDES-2 latest keps

Hi Larry. I'm not aware of decode software yet but the crib to help you is here https://goby.nrl.navy.mil/ANDE/Castor.html and here https://goby.nrl.navy.mil/ANDE/Pollux.html To load the keps into Orbitron, cut the keps from the e-mail and paste into a text editor (notepad for instance) Save it as a plain text file. From Orbitron, click "LOAD TLE" and find your text file. FX25 interface details don't appear to be available yet. I'm confused now about which object is which. Either space-Track has muddled them or they have swapped positions. I think the Space-Track mis-identification is more likely. Larry Teran wrote: > Hi!
