Look for the youtube video shot from the roof of the VAB. You can hear the

in their audio feed.

Ollie,
I have used Stuf since the 90's when I was doing Satellite TV installations ie.
BUD dishes. It works very well. The only thing the paste is very slippery like
Teflon, so once a connector is filled with Stuf and tightened, one must wipe
off the excess with a towel or paper towel otherwise

Has anyone on the list tried using a Kenwood TS2000 on full duplex satellite
operatation using a dualband VHF/UHF antenna and a diplexer? Is it possible or
is there too much desensitization thru the diplexer to make full duplex work?

Not that brand but something similar. Used it on TV satellite, and

Hi John
Let me try tomorrow and report back, I have never tested this.

There's probably less desence than using two antennas without diplexers/filters.

It works fine.
Used a TS2000E via a MX2000 tri-plexer to a co-linear both u/v and v/u with
no problems. Worked the States and Canada this way via F0-29.
Also used a Create CLP5130 log periodic connected in the same way.
Just keep the TX power as low as is needed to hear your own signal and no

Hey fellow sat-hams,
I have a few technical question about AO-51.
1) In V/S mode What is the average output power?
2) What kind of antenna is used on 2.4GHz and 1.3Ghz?
3) What is the sensitivity of the 1.3Ghz receiver?
4) Some where I reeded that AO-51 has an HF receiver? If it true, for
what is

Traveling north to upper BC and on into Alaska. Can anyone send me information
on how to use the ISS for APRS positioning and for packet communications. Also
any info on the other other Leo's that I can work with? I think I need the path

The sensitivity is -117 dBm for 10 to 12 dB SINAD.

Hi!
Last weekend was a busy weekend. Starting with a 3-hour drive
from Phoenix to Show Low in eastern Arizona on Friday (4 June)
evening, a hamfest in Show Low on Saturday (5 June) followed by
operating from a nearby grid boundary, to a longer drive north
with a 5-hour drive home on Sunday (6 J
Hi!
I will be in north-central Arizona on Saturday, 12 June, and
should be able to park along the DM34/DM35 grid boundary for
passes in the late afternoon and early evening on 3 satellites:
AO-51, FO-29, SO-50. I should be at the grid boundary around
2300 UTC, in advance of an AO-51 pass at 2336
Thanks David !
My vertical did not pick up AO51 at all, so the experiment
could not be done here. Using my beams all was fine of course.
Funny, I knew this stacked vertical dual band only picks up
signals at low elevation (<10 degrees), at many cubesats (70cm)
and ISS (2 mtrs). But I never experi
