I agree on the possibility of some line loss to the unit. The longer the
coax run the more problems you may have with it properly switching. I
found this to be especially true of the early models of the Mirage mast
mounted preamps. Even the power "T" can be a problem if the wire run is
long. Presently, I am using my unit on the IC-910 without any problems,
but the coax run is less than 50' of 9913. I would recommend holding
onto the KP-2 for awhile. If the rig is border lined with the output
voltage being around 12 volts instead of around 13.8 volts, there could
be enough loss (even .5 volts) can cause erratic operation. Using the
KP-2 allows you to use a separate voltage allowing sufficient amount to
the preamp.

On this, would it be possible to power preamps for 70cm and 2m through coax
if the antennas are split using a diplexer? Or would 12v go to both on TX
and fry one of them?

My thanks to everyone who has responded. 4 out of 4 say it's ok to use the
847 to power the preamp.
I put up the 432 one today, but with the KP2 control box, just in case. But
I will go ahead and remove the box, and let the 847 power it.
One interesting response was to be careful if there is anything inline
between the rig and preamp. Lightning protection, or even an SWR power

Look carefully at the power consumption on the preamp. If it is less
than the max for the 847 (which I forget the maximum current), you could
use it powered from the radio. BUT pay careful attention that anything
between the radio and the preamp does not provide a dead short from
center conductor to shield. In my case a lightning protection part shows
as a dead short. This would of course zap the internal power supply
parts in the 847. In my case, I just provide external power and hard key
the preamp from the radio. (The preamp is actually in the shack not on
the tower.)
Another problem in my install is I am using a pair of duplexers to
combine the 2m and 70cm to run in a section of 7/8 hardline. The 2m
ports pass voltage. The 70cm ports do not and present yet another short
circuit on the coax. I do this arrangement to gain the low loss for a
150 foot run to the tower base. I also benefit using this technique to
avoid interference problems between 70cm and 2m. This gets me about
120db of isolation between the two ports.
There is also another possible issue to consider in that the 847 when
first powered up sends a full power transmit for a very short time. Also
another stupid pet trick is never plug into the data port when the radio
is on. Seems simple, but when the tip/sleeve/ring cross the right
contacts, a full power transmit occurs. Yup, cost me my best preamp
while playing the Arecibo EME fun a while back.

Depends on how the diplexer is used. In my case, I use two units to
combine and split 70cm/2m after a long run in hardline. The diamond mx62
units I use pass dc only on 2m and 70cm looks like a dead short.

You can't compare reception of ARISSat-1 to the ISS... The Kenwood radio on
the ISS transmits with something like 20 times the power that ARISSat-1
does! How well you hear the OTHER low earth orbit satellites like AO-27,
AO-51, and SO-50 will tell you a lot more about the effectiveness of your
setup.
That being said, a preamp makes a HUGE difference.

Could be this is the missing link explaining why i burn 2 preamp in the
past? but i always put the power knob at minimum when i turned
off the 847. I will have to test it as i measure about 5W even if the RF
power is set to 0!! Full power i'm not sure but even 5W is enough
to kill a preamp

If you do get one, I'd like a copy as well. The tuning bit is easy, you
just multiply the incoming complex signal by a rotating vector. Want to
tune higher? Spin that vector a little faster!

I've successfully run lysdr on a 1400MHz Celeron M at 48kHz, although I had
to back off the screen updates. The FFT is actually quite fast, but screen
updates with the Intel chipset tend to slow things down. I considered using
FFT convolution to replace the FIR filter, because the FIR is *really* slow.

Evidently a very popular download as I see the Google limit for today has
been exceeded.

Strange one this, story appears to indicate that a student satellite from
the Sharif University will go into a 36,000 km orbit.
http://news.xinhuanet.com/english2010/sci/2011-08/09/c_131036680.htm
Their domestic launch capability might appear at best to be 500km, Rasad-1
was 260 km ( pic of 465 MHz downlink at http://www.r00t.cz/Sats/Rasad ).
Might imply an overseas launch or else something got lost in translation.

For those looking for FM27, I'll be on the FM Easy Sats on Saturday the 13th
and possibly Sunday as well. I'll probably be operating from the beach of
Assateague Island IOTA NA-139.
Hope to see you there,
