Hmmm, S-band is probably too noisy for the really weak return signal. It might
be physically too small for L-band, though that's a pretty quiet place. Maybe
something on C-band? C-C Rider on Balloon Bounce?
If this thing works, I wonder how big a balloon we can stuff into a Cubesat?

Hi!
Field Day was fun, even if my contest was only a Saturday event.
I did not stay out for the whole time, but enjoyed being in the
mountains in a forest playing radio. I also had a chance to make
some QSOs on HO-68 about an hour or so before the start of Field
Day. A good way to avoid the
Hi Folks,
I have just checked with the hotel, the Holiday Inn at Guildford, and they
have reminded me that they will release our dedicated rooms on 9 Jul. So
there isnt a great deal of time to be sure of a room.

According to the Space Track, NEGAI reentered at 26th June.
As I reported before, Keps data shows the reentry day is around 21th
June.
Which is true, Keps data or Recent Satellite Decays on Space Track???

Hi Greg, KO6TH
Echo-1 A was a passive communication satellite launched on 12 august 1960
in a circular orbit at 1519 - 1687 km and it was a balloon 30.5 meters in
diameter made of 0.0127 mm thick metallized mylar polyester film to reflects
signals transmitted from the earth at 960 MHz and 2390
They've reinvented Echo-1.

Of course, that one was 10x larger.
What makes this a 10m (band) operation?
I expect it would work on the higher bands ...

There is a list of codes somewhere. To speak one of the pre-set
words, you just include the text %XX where XX is a two byte HEX
value of the word you want spoken. I guess you could just try
all 256 codes and write down the words

I remember Echo very well. As Domenico stated it was very visible. I
remember my father taking my siblings and I outside to view. He
certainly had my attention then.

website.
I told them to look at all the satellites.
They found the site had all satellites on it.
When they brought up the sats they didn,t put on the

Dear Friends,
For linear transponders, it is customary to receive in USB.
So, if the transponder is non-inverting, TX in USB. If it is
inverting, TX in LSB.

Jerry,
Linear satellites today use LSB for the Uplink and USB for the downlink by
general agreement.
Also by agreement:
CW is on the lower 1/3 of the downlink bandpass.
Mixed Modes are in the center 1/3 of the downlink bandpass.
SSB is in the top 1/3 of the downlink bandpass.

David and I will be working a few passes tomorrow afternoon from Rulo Nebraska
(EN20gb). We will probably work from the Lewis and Clark Camp Site on the
Nebraska side of the Missouri River if it gives us a fairly clear view of the
passes. We are planning on working the AO-27 pass @ 1922z,
