Hello,
We are looking for a UHF amplifier (430-440MHz) for a transceiver to go from
10 mW to ~ 75W. Most of the amps were are funding require a much stronger
input power than we can do. Note, it's a transceiver, so we want to be able
to receive through the system as well. This is for half duplex
Armando, that's correct, E1P and RAX-2 are now on different frequencies.
Thanks to the IARU for helping us coordinate!

All, the satellites below are on schedule for launch tomorrow morning.
Launch will be viewable here:
http://gs.engin.umich.edu/predictions/tle_elana3.txt
The initial keps are here.
http://gs.engin.umich.edu/predictions/tle_elana3.txt. RAX-2, MCubed, E1P,
and AubieSat are all trackable by most OSC
Launch was great. PPods have deployed! First transmission in about 30
minutes or so.

Thanks for all the tracking help.
We haven't heard from MCubed yet. Hoping for the best.

Hi Carl, I have not used AGWPE before as a TNC. How does it output it's
data? A virtual serial port?

All,
Thanks for the tracking on RAX-2. Everything is looking great.
Could you try tracking MCubed next? We have been unable to hear so far.
Satellite: M-Cubed (1)
Downlink Freq: 437.485MHz
EIRP: < 1W
Modulation Scheme: FSK
Protocol: AX.25
Baud Rate: 9600

All,
Does anyone have any recommendations on high quality mast-mounted preamps
for UHF? We're using the Icom AG-35 and not happy with the noise figure.
We're going to try an adjustment described here
http://www.eham.net/reviews/detail/6116.
We are looking at the amps from ARR and SSB. Any othe
Mike, that's great! You're the first to decode, well done!
Any idea why the beacons show in the list at the bottom all have the same
time stamp?

Dear Graham,
There was nothing special in the separation systems between the 1U's from
the ELaNa 3 launch. They are certainly close together, in fact there are
three 1Us we think in the link group. Object F appears to be AubieSat and
Object G is E1P. MCubed is somewhere in between it seems.

Dear AMSAT,
Has anyone successfully increased the maximum FM deviation of the 910H when
using the 9600 setting on the radio? We have not been able to. We have
two units, and one is maxed at 2.5 KHz and the other at 3.2 KHz deviation.
We've used the service manual to adjust the deviation to max

Dear AMSAT Community,
As we have done in the past, we are surveying the community for ground
station capabilities. The goal is to estimate how much capacity the
community has and our ability to support a variety of missions.
The survey is located online at: http://gs.engin.umich.edu/gs_survey/

Nick, we think we picked up CAPE-2 this evening during the 5:48 pm pass
over Michigan. We saw a nice Doppler shifted signal centered at 437.325.
See attached figure. It shows 2 doppler curves centered around 437.325
and around 437.405.
