Actually I would like to see something like the FT817 does, where you have 6
or so antenna jacks on the back and you can menu select the jack for each
band, so you could put 6m and 2m on one jack if you have a dualband antenna,
or put 2m/70cm on one, etc.

Dear satellite enthusiast and DXers
The 3W6C-Team will activate C?n C? Island (AS-185) on satellite from
April 10 to18. The crew use a FT-897 TRX with homebrewed
"Easysat"-antenna for 2m and 70cm and a homebrewed 10m crossdipol.
Following satellite will be use:
- AO-07*
- AO-51*
- HO-68*
- SO-50
- SO-67
(*first priority - not all overflights and sats will be use)
Please note, that only AO-07 will be activate in SBB/CW-mode. All other
satellite are use in FM-mode.
The main areas in the Foodprint are: East-Asia, Japan, China, India,
Australia and east part of Russia. If possible, so the 3W6C-Team will
use some DX-Windows to near East and west part of Russia.
Operation note:
The main-operator for Satellite is HB9BXE, Hans-Peter. Hans-Peter don't
use a CAT-Interface for doppler correction. The equipment is in full
manual use. It is important to know, that Hans-Peter don't hear his own
downlink. For AO-07, he made no doppler correction in the uplink.
Hans-Peter will search some signals +/- 5kHz arround the
downlinkfrequency. (quasi splitmode like shortwave).
Is there a pileup on the sat, please use only callsign, signalstrenght
and gridsquare.
All Crewmembers are primary shortwave operators. So please be patient,
if they have some troubles with the sat-operation.
For additional information and operating-plan, please contact the 3W6C
Website. www.3w6c.qrv.ch <http://www.3w6c.qrv.ch>
Important:
We still search Pilot-Station for coordinate the activities from
following Areas: Australia, India and central Asia. If you like support
the 3W6C-Team as pilot, please contact the team-leader hb9bxe
(hb9bxe@xxx.xxx
Thanks for support of the 3W6C-DX-Pedition.

Dear Tom:
Thank you very much for reminding us of the Flex product line. They have
progressed a long way since the last time I looked into SDR. I will review
the specifications of the Flex-5000 very closely. It does appear to be
clearly the next generation of competition grade/satellite transceiver

NASA scientist Richard Gross and his colleagues at the Jet Propulsion
Laboratory in Pasadena, Calif., calculated that Saturday's earthquake in
Chile shortened the day by 1.26 microseconds.
An earthquake can make Earth rotate faster by nudging some of its mass
closer to the planet's axis. That's the same way that ice skaters speed up
their spins by pulling in their arms.
Please adjust your satellite passes accordingly.

Message-ID: <203748.57109.qm@xxxxxxx.xxx.xxxx.xxx.xxxxx.xxx>
Content-Type: text/plain; charset="us-ascii"; format=flowed
Mike,
As others have said, just log it twice, once for each grid.
The portable and handheld designations are commonly used on
satellites. Portable can have many meanings. Some use it
to say they are using an HT or operating on batteries.
Originally, the portable designator was used to indicate you
were not at your home QTH.
In the 60's and earlier, the FCC was much more controlling
of amateur radio than they are now. If you were not at home,
you were obliged to sign /mobile or /portable on voice or
on CW, /8 if you were in the 8th call area etc. If you moved
out of your call area, you had to get a new callsign with the
proper number for your new location.
If you were to be away from your home QTH for more than 72 hours,
you had to tell the FCC Engineer in Charge of your district where
you were going to be operating from. If on a trip, you had to
supply an itinerary telling them where you would be on a certain
day. The FCC wanted to know where the transmitters were and who
was operating them.
Another requirement was to log every contact. If the FCC came
calling, you had better have your logbook available. There was
a requirement that you operate so many hours in a certain period
of time in order to renew your license. In the early days, the
FCC was feared. There were lots of rules to follow. A mistake
could cost you your license.
Today things are much different and the rules are very friendly.
But signing portable still has meaning when it indicates you are not at
home and possibly operating in another grid. When you hear "portable,"
it gives a hint that you might want to check your grid list to see
if it's a new one. It also might influence you to give priority to
the "portable" station since it may be operating under less than
desirable circumstances, out in the open, on the side of a road, out
in the rain etc., for the primary purpose of handing out a new grid
for those who are paying attention in their comfortable hamshack.
Of course, many use "portable" when they are at home with an HT. If you
hear me signing portable, you'll know I'm not at home. Time to check your
grid list.
73,
John K8YSE
