TAPR EasyTrak?
by Joe Leikhim 12 Feb '07

12 Feb '07

Is anyone using the TAPR EasyTrak controller? I have one of these I picked up a while back. I have not tried it out as the documentation I found was limited. Can someone help me out? -- Joe Leikhim K4SAT "The RFI-EMI-GUY"© "Treason doth never prosper: what's the reason? For if it prosper, none dare call it treason." "Follow The Money" ;-P

RAFT Voice
by Paulo Pinto 12 Feb '07

12 Feb '07

Hi, I was trying for the second time RAFT voice with my recorder ready to register any feedback from the satellite. I was repeated 2 or 3 times.it was wonderful. The problem is that I realized after that my recorder was in PAUSE mode. Does anyone has a recording of my TALK message ? UTC was around 00:12. Thanks CT1ETE, Paulo

Hello, I am looking for 2 Used SPDT 4 port type N Coaxial Relays such as the Teledyne CS-29N1S1 or similar. Break - before - Make is a must. Minimum isolation of 60dB @ 432 Mhz, and Capable of 1KW Keydown. Coil voltage 28vdc or 12 vdc. I am not concerned with appearance, as long as its not damaged, and operates flawlessly. If you only have one let me know anyways. Thanks -Steve Raas N2JDQ FN20vg

Re: CW and Doppler Corretcion / other stuff
by Wayne Estes 10 Feb '07

I use a SatPC32 tuning increment of 50 Hz for SSB and 600 Hz for FM. A smaller SSB increment would give more natural sounding audio, but require extremely frequent tuning changes during the middle of a high elevation pass. This could be a problem if you control the radio at 4800 or 9600 baud. I control my FT-847 at 57,600 baud. At the beginning of a satellite pass I use the FT-847's Sub-Tune knob to fine tune my uplink. I never use the SatPC32 uplink and downlink calibration click buttons. If the other station drifts across the passband during a QSO, I tune them with the radio's main tuning knob (which tunes both downlink and uplink). That way my next transmission will come down on the same frequency as their last transmission. In summary, I tune the radio normally and let SatPC32 handle the Doppler correction when I'm not manually tuning. That is the whole concept of "transparent" Doppler tuning.

CW and Doppler Corretcion / other stuff
by sraas＠optonline.net 10 Feb '07

10 Feb '07

Just a quick question , Im running SatPC32... and just got my bencher hooked up to the rig. Worked a few stations and its loads of fun, however.. I'de like to know a few things...I have my program set up for 10 hz resolution, so every 10 hz it changes ( trying to keep it steady). What do most of you have it set for? Also is there a 'portion' of the birds ( any bird ) downlink that should be used for CW .. ie.. keep CW low.. and keep ssb high? I'm sure there is a nice learning curve to working cw on the sats.. pen in one hand... finger on downlink calibrator button for the pc, while sending code. The antennas here are broad enough that i can lead the bird.. and make a cq and be ok with a good downlink...so thats really not becomming an issue... yet. Thanks! -Steve Raas N2JDQ FN20vg

Re: Icom PCR-1000 PC controlled receiver
by Joe Leikhim 10 Feb '07

Bob; Why would that baud rate be a limitation? Could you get a couple RS232 to Fiber Optic modems or at least some copper RS232 line extenders (Try Black Box) and make it work? Message: 2 Date: Fri, 9 Feb 2007 17:05:45 -0500 From: "Robert Bruninga" <bruninga(a)usna.edu> Subject: [amsat-bb] Icom PCR-1000 PC controlled receiver To: <amsat-bb(a)amsat.org> Message-ID: <03fc01c74c96$72bb9590$42577a83@SGSbb> Content-Type: text/plain; charset="us-ascii" Does anyone have a PCR-1000 ICOM remote controlled receiver? How long can the serial port cable be? I heard it was operating at something like 112,000 baud and could not be run the 200 feet to our roof. This makes it a deal breaker. Is there a better all mode all band remote controlled system for roof mount to avoid long cable runs for satellite receiption across all bands..?
