I agree whole?heartily?with the use of phonetics any time ! anywhere!. lots
of old ears out there, (mine included) but not just that, conditions on any
medium is always subject to?degradation,Faraday,phaseshift,doppler,you name
it-It can happen.especially with the "E" sounding letters,namely T,Z,E,B,C,V
to name a few. I can't count the times I called for another ID to get one of
them that I missed the first time around. Even under ideal conditions, not
everyone's?grammar?and?.diction is?understandable. My other pet peeve is the
use of improper phonetics, The world has one set, use them only, I don't
like hearing "Zebra, Zink,Zorch!!" for Zulu. A few Good operatiing practices
makes for an enjoyable Qso, not just a "zip it lip it,get on with it,and
wheres the next guy?". My two cents worth.:-)Thanks 73 Gud dx ! Happy Dx

Sanjay Srikanth Nekkanti, AB3OE, confirmed that SRMSAT has passed all the
required tests and is now at ISRO's spaceport, Sriharikota, ready for the
Oct 12th launch.
The downlink and ground station details for SRMSAT can be found on AB3OE's
page here:

At the moment, I have no information about JUGNU. Will keep you all posted
as and when I get more details.

Hi,
While I do agree with the below, one thing we should keep in mind though is
that there's a difference
between a pile-up on HF and on an FM sat. Not everybody on the sat may be
actually interested in
working that particular station so we also have to give those some room (in
that 10 minute pass). On
HF the time it takes to work the pile-up is usually a lot longer than that.
One thing I'd be interested to explore though would be how many of the folks
that work the FM sats
regularly actually do work DX on HF and often find themselves in a pile-up
trying to get through
quick and clean. This is out of pure interest and may help make it easier
for some.
The other problem is that before the madness starts, there are always other
stations already working
contacts before the "rare grid" station comes into the footprint.
Of course the best solution would be to get on the linear birds, we all win
the lottery so that we can launch
another Phase III sat or two and it would'nt be a problem anymore. (Ok, ok
.. just teasing).

good operating practices will improve rate. This procedure also satisfies
those, mostly weak signal ops, who want a valid QSO to consist of both
stations copying both calls, a significant piece of information (grid
square), and then confirming that the information has been exchanged. This
is a valid point, although many, particularly on HF do not necessarily agree.

Hi Dinesh,
Perhaps some clarifications are in order.
The IARU has frequency coordinated SRMSAT at 437.425MHz for the down
link with no mention of coordination of the uplink. The link you
provided says the downlink is 434.5 MHz which puts it outside the
435-438 MHz satellite band. Additionally, it mentions an uplink at 145.8
MHz. right at the lower edge of the 145.8 to 146 MHz satellite band.
The referenced web site, www.srmsat.in, is not functional, so recent
information is not available there. Do you have any other reference links?
Regards...Bill - N6GHz

Good points Mike.
I agree that not everyone on a satellite pass is interested in working the
'rare' grid.
However if someone goes to the trouble of setting up a portable station for
the benefit of others to grab a new grid, I think those users who aren't
interested in chasing grids should standby while the others attempt to make
contact with that station. After all, with the short pass on the LEO birds,
there isn't much time to do anything else; unless you get on during the
early morning hours, or during the middle of the day when the activity isn't
as high as on the weekends and you can actually have a 10 minute QSO with
someone.
As far as the linear birds are concerned, I have a Yaesu FT-847 that's
dedicated for satellites. It's interesting that most of the time I get on
the satellites, is on the FM birds! Unfortunately, that's because most of
the time I get on the linear birds, there's either no one on there, or
perhaps just one other station.
It's funny that many times when I do make a contact on a linear bird, the
other station wants to just follow the FM procedure of exchanging grids, and
not much else, even though they still have a lot of time left in the
footprint. I personally like to chew the rag on a linear bird (and on HF),
but that doesn't happen very often on the satellites.
While we can all continue to hope for a HEO, and try to encourage those who
do have the gear to get on the linear birds; the fact is the FM birds are a
victim of their own success.

There are no Global Primary Amateur and Amateur Satellite Service
allocations between 146 MHz and 24 GHz.
Access to spectrum suitable for weak signal work in the 146-3500 MHz region
is crucial for the Amateur Satellite Service. It is encouraging to read on
page 2 of the September issue of the ARRL Spectrum Defense Matters newletter
about the formation of the IARU Spectrum Futures Committee.
The aim of the Committee is to develop strategies for retaining access to
bands above 148 MHz for the amateur and amateur-satellite services globally.
In the past it seemed that IARU was only interested in HF and ignored the
UHF and Microwave spectrum, so the formation of this committee seems a step
in the right direction.
