Hi All!
I will be operating portable from the EN90/EM99 gridline tomorrow afternoon
from about 1800z-2045z. I know these are not rare grids, but I have spoken
with a few of you that need them. I finally got a little break in school, so
it sounded like a good time to make a road trip.

I received this query in an email from Luis, LU6QI. Perhaps someone is
in a position to respond.
I am trying to attempt a qso with USA via AO7 or FO29. It could be
possible with some station from Florida, Do you know
who could be in conditions to make this try?

I could try, could you send me his email address? I've worked northern
Argentina before on LEOs, and would like to try some of the other
countries there as well.

There is a link off of the AO-7 resource page for a logger for scheduling
contacts but it doesn't work.
Does anybody know of a real time/near time reflector for scheduling more
specifically AO-7 contacts or even a general reflector covering all the
satellites?
Thanks in advance and 73,
I know that when stacking antennas for different bands on the same mast, the
general rule of thumb is to space them at least 1/2 of the boom length for
the higher frequency antenna. Does this rule also hold true for stacking 2
antennas on a horizontal crossboom? If I want to put a 2m and 70cm
No, not what WE call a full-duplex radio.
But you can monitor the FMN broadcast band ion the left side, and have a ham
freq on the right side.

... but Kenyeacomco Model XYZ-123 claims it is full-duplex ...
Several of us have tried for years to properly educate the manufacturers and
marketing departments of ham radio transceivers. What they term full-duplex
is usually a radio with two, independent VFOs - but the sub-band can NOT be
He asked, if it would do V/U or U/V full duplex, and yes, it most certainly
does.

AO7-mode A. I need my 8-element 2m yagi to do better. Since the
support tower is out of commission until spring, I could move the

LVB Tracker with KR-5400A Controller.
EEPROM does not hold calibration after Controller is turned off for a while.
Do I have to go thru the calibration procedure every time it is turned on?
Am I missing something here?

Spot on. It has to be full duplex for cross band repeat to work, whether
the guys who write the manual, marketing literature, or QST review
realize it.
That's correct, except that the radio doesn't need to be able to use
the mic or speaker while in crossband receive mode, so it is

Hi John. That old rule of thumb does not apply for modern antennas (and
never did except for fairly short antennas). You need to know the aperture
size of the antenna, and stack them at half of that measurement - for
maximum gain, but somewhat closer if you are interested in a better pattern
... It cross-band repeats, which means it will receive on on band while
transmitting on the other, doesn't it?
But the AMSAT mantra for working the FM birds has been work 'em full duplex,
so you can monitor the downlink as you transmit. Being able to cross-band
repeat does not necessarily
Hi again John and all.
Sorry, I made an error in my description. For minimum interference (or max
gain) you need to stack so the apertures just 'touch'. So for two identical
antennas, if the aperture is 9 feet then the 'edge' of that aperture is 1/2
the aperture diameter, or 4.5 feet. That was
This might give some insight John

It would be better if the other antenna was anything but 432.
