My best DX on AO-40 was VK5DG south Australia from central england.
70cms up? 2.4GHz down.
Happy days !!

Hi,
For a small club satellite presentation I will be mentioning the
benefits of HEO over LEO and the range advantage.
Can anyone tell me the distance record set when AO-40 was alive?
Thanks

We had another favorable break at midday today when the ship's speed was
slowed by a convergence current for a few hours that caused us to still
be in EJ78 long enough to get that grid into a few logs on AO27.
Later this afternoon, my FT897D failed unexpectedly, but I was
eventually able to bring it back to life for the most part with a
firmware reset. A few of the menu options are still gone - they're not
disabled; they're actually missing from the menu! - so I'll be on the
horn with Yaesu tomorrow to see what they suggest. Hopefully the rig
will remain functional at least until I get to Florida next week.
There were two planned passes while I was up on the flight deck trying
to get the 897 back on line. One was AO51 at 21/2247Z, and the second
was AO7 at 22/0003Z; both for EJ77. I'd just gotten the 897 back up in
time for the AO51 pass and made a few contacts before the rig died
again. More resets later, it came back up and stayed mostly operational
for AO7's pass.
Unfortunately, several ops didn't hear me answering their calls, but for
some reason they kept calling anyway. (HF DXers do the same thing, but I
still don't know why!) After a few minutes of making just a couple SSB
contacts, I gave up on that mode and switched to CW on the same freq.
This move got a few ops into the log who otherwise would have lost out
on the grid because of the non-stop calling QRM. CW comes through again!
We'll be arriving at the Panama Canal Wednesday morning, but we haven't
heard yet from the canal authorities what time we'll begin our transit.
We're expecting to have to sit for a short time, but we'll likely get
into the canal sometime during the morning daylight hours.
In case you're interested, the Canal Authority has a website with a pair
of web cams set up to watch ships passing through at each set of locks.
'll leave my step ladder satellite station set up on the side of the
flight deck nearest the cameras. Let me know if you get any screen
captures of the station and the bald guy next to it!
The web site is:
www.pancanal.com/eng/photo/camera-java.html
Near the top of the screen, you'll see a list of links in a horizontal
line. Look for "Miraflores Locks" and "Gatun Locks". We'll be coming in
from the Pacific side of course, so the Miraflores Locks web cam will be
the first one we pass by. I'll post a note to the BB when I've got a
better idea of when we'll be hitting the Miraflores Locks.
By the way, the images are stills rather than streaming video, but
depending on your connection speed, they'll update every few seconds.
Here's the list of passes for tonight and most of tomorrow. Since we'll
be waiting for arrival instructions from the Canal Authority, I won't
make an extensive list of passes, but the following info will take us
into FJ07 with FJ08 and FJ09 being tomorrow night and Wednesday.
FO29 - 22/0907Z - EJ87
AO51 - 22/0933Z - EJ87
AO7 - 22/1225Z - EJ87 or EJ97
AO51 - 22/2207Z - EJ97 or probably FJ07
FO29 - 22/2223Z - EJ97 or probably FJ07
AO7 - 22/2302Z - if still in Mode B; probably FJ07
VO52 - 23/0149Z - FJ07
FO29 - 23/0813Z - FJ08 or FJ09
AO51 - 23/0853Z - FJ08 or FJ09
Probably, not sure but will try
VO52 - 22/1337Z - EJ97
AO51 - 22/2030Z - EJ97
FO29 - 22/2037Z - EJ97

I thought that the FT-817'a front and rear antenna jacks could only be
switched from the default config out of the box ...
FRONT - 50mHZ, 2M, and 440
REAR - HF work
... and vice versa using Menu Item 7.
But is that Menu Item more sophisticated than that? Someone just wrote me,
indicating that they could make the front jack 2M and the rear 440 - by
choosing Menu 7 while working 440, and selecting "REAR." Then work 2M, and
select Menu Item 7, and choose "FRONT."
I've never had to split it like that, using a diplexer with my sat beams.
Can that be done?
Quizzically yours,
Clint K6LCS

Yes, it can. Just as you describe above, you can select the
antenna socket for each of the 3 non-HF bands, and all of the
HF bands are covered by a single selection through that menu
option.
Keep in mind that you will see slightly higher power consumption
when using the rear (SO-239) antenna socket than with the front
(BNC) antenna socket. The 817s use a relay to switch between
the two ports, and the default (unpowered) setting with the relay
is for the front socket. The relay must remain powered when the
rear socket is selected. In my opinion, this is a minor design flaw,
but one that Yaesu has not changed since the original 817s from
over 10 years ago.
For my operating, using a pair of 817s for SSB/CW satellite work,
I use the front antenna sockets on my 817s to ensure I'm not
drawing more power than necessary to use these radios. I stay
with the front sockets when I use these radios on other bands
for the same reason as I do on the satellites.
73!

Disclaimer: doing this from memory, always dangerous
I believe that the HF bands are treated as one setting but 6M, 2M and 70 cm
can
have the antenna port set individually.
I know that my favorite configuration is to use the rear port for 6M and the
front port for 2M and 70 cm.

Hello John and everyone else.
According to the logbook that contact was around 2.5 degrees
elevation which is very close to my horizon. My best distance would
probably be a contact with EI4HT.
Another feature of AO-40 which may or may not be relevant to your
talk Pete, was the variety of uplinks and downlinks. One of my most
memorable
contacts was with OE1VKW. I was using U/S, he was using L/K. Four
bands for
one contact. Mind you, he was doing most of the work for that one.
Maybe not specific to a HEO, but SSB/CW on K-band on a LEO would
be extremely difficult. Having an almost stationary HEO made it possible.
Happy days indeed.
