What are they about? That's why the links were posted ... (grin)

Sin'en2's mission is ...

To establish a mutual communication technology between the earth and a space probe in the lunar orbit

And ArtSat's site tells it all ...

OK, what are these payloads suppose to do?

Betreff: [Work-Sat] Diplexer Arrow 10 Watt Duplexer for 146/437-10



Hello,

I have recently got a new duplexer and I made some comparisons with the 10
Watt Duplexer for 146/437-10 I already had.

The 10 Watt Duplexer for 146/437-10 shows nearly 1 ohm dc resistance
between the inner conductor at the output and the VHF input. The other
diplexer shows just zero or so as expected. Where does the 1 ohm
resistance come from?
I checked the SWR with an HF antenna analyzer and a good dummy load. The
VHF part of the diplexer should be a low pass filter so I expected a flat
response at HF. Instead the Arrow Diplexer shows SWR 1:1 only up to 3.7Mhz
then it increses over 2:1 at 14 and then it tends to get better at 50Mhz,
but still not 1:1. The other diplexer is fine. Why these differences? Can
you get similar results?

Re: Diplexer Arrow 10 Watt Duplexer for 146/437-10

clintbrad4d@...
 

What device are you using that measured the "one ohm" result?

Have you worked a satellite with your Arrow antenna? Or seen the improvement it makes with local repeaters? 

Part of me just wants to know WHY you are spending time analyzing an antenna that has made working satellites wonderful for thousands of hams ... instead of walking outside and USING it!!! (grin)

Re: WTB: 2 meter amp for satellite use

Siegfried Jackstien
 

Mount your antenna around 20-30 degrees upwards

Your 7el is not a high gain antenna with a radiation pattern like a needle ... so lift it up somewhat and you should have a good signal to the sat nearly all the time (only when straight above you it would not work)

But ... most sat passes (around 80-90%) are not direct above your location ... so then a slight tilt is okay for working over the sat

What about building a qfh?!? (or eggbeater or tpm2)

Hi Scott,

Don't have elevation or circular polarized antennas-just an old Cushcraft
or Hygain (don't remember which) 7 element horizontal, so it takes a
little more to get into the satellite than my Icom 706 original puts out
at 10 watts.

You won't need that much power to work AO-7. I have never
successfully worked though AO-7 but I have a IC-820 that has 5 and 45 watt
settings and have never needed more than the 5 watts into a gain satellite
antenna on the uplink for FO-29, SO-51, or VO-52 when it was active.
Lower power the better. Scott, KA7FVV
