Has anyone replaced the female N connector on the IC 471A, 25 watt
tranceiver PA module? It seems as if the heat sink is trapped between the N
connector barrel and the PA circuit board. Unless the connector barrel pulls
off of the pin, I see no way of removing it, or the circuit board to get at
the pin. I don't want to use to much force in pulling off the barrel.
Perhaps heating the pin might release the barrel. Any suggestions? Should I
send it to Icom and let them worry about it?

We have been very close to the low battery trip points due to continued
attempted use in eclipse in the southern hemispere. I'll try to reset
things first available pass, probably tomorrow AM EDT.

Hi Drew,
Well the southern hemisphere is a big place and I can assure you there is no
operation in eclipse from VK/ZL. I monitor almost all evening passes here
which occur shortly after the eclipse and on a number of occasions I have
noted that the transponder was on at my AOS. It also tends to drop out
shortly after AOS so given the length of the timer this would indicate a
turn on somewhat south of ZL. This would also correspond to the time AO-51
comes out of eclipse. My first guess would be that sometimes the
transponder is triggered as it comes out of eclipse as there are no stations
south of ZL to trigger it. There is also continual switching between the
normal and reduced power levels during the evening passes. I presume this
indicates a marginal condition so perhaps usage down this way should be
limited for a time after eclipse as well to give the batteries time to
recover.

I'm looking at a Whole Orbit Data file right now from 6/12 that
indicates use at 2116Z and 1758Z, over Australia and New Zealand, in
eclipse. Other files show similar patterns. I'm sure however that we
will have the exact same problems, and worse, over the northern
hemisphere during our winter eclipses! It may also be that the PL
decoder is occasionally decoding falsely, which would mean a longer
sample time might help.
The software does not increase power after eclipse until a set voltage
is reached. I think the solution will be to lower the intermediate power
step to zero, as the low one is, and then there will be no use possible
during eclipse, but also with occasional periodic dropouts during poor
attitudes during the rest of the orbit. Regardless, my comment was not
meant as a slight to anyone, and was merely based on observation of the
WOD. We can see pretty much everything that happens in 30s intervals.
Thanks for the observations.

Hi Drew,
The point of my email was to suggest that based on my observations, and
knowledge of operations "down under", the fact that AO-51 is sometimes on in
eclipse may not necessarily be caused by bad operators. There seems to be
evidence to indicate that the transponder can be triggered for other
reasons. There is only a very small group of regular operators in VK and I
am the only currently active ZL on AO-51 and we are all well aware of the
eclipse problem. A turn on at 1758z for example is 3:58am local time in VK.
None of the regular operators operate at that time of the day. I can not
guarantee of course that some rogue operator who never otherwise appears on
the satellites is triggering the system but it seems unlikely.
As a general observation I would point out that operations in this part of
the world differ markedly from the Northern hemisphere. I have never to my
knowledge exchanged a grid square. A typical pass consists of 2 to 5
stations, all well known to each other, and we simply have a round table
discussion. It is this fact that gives me reasonable confidence as to
whether or not there is operation in eclipse.

As much as I hate to say this, but I agree, given the state AO-51 is in. If
only to prolong its life, I vote to turn it off or switch to a less used
mode...just my two cents.

The Southern hemisphere is a fairly large area, please be more specific. The
statement you made creates doubt about our operating habits implying that we
are irresponsible operators.
AO-51 is not in eclipse whilst it in range of Southern Africa. This is based
on the information as given by SatPC32.

While verbal reports like this have their use, I would like to remind
everyone of the excellent service at http://oscar.dcarr.org If you
have reason to believe the satellite is down, be sure to indicate this
fact on that website so that others can confirm their suspicions at a
glance. Likewise, logging successful use is helpful for all concerned,
especially in a volatile situation such as AO-51's current one.

Hi All.
I am looking for any Information on 2 Mutek Preamplifiers I have, One is for
2Mtr operation type GFBA144e and One for 70cms type GLNA 432e.
The 2mtr one has a 4pin female connector on the front labeled "CTRL" and 2
"N" type antenna sockets marked "Ant and Tcvr".
The 70cms one has a 3pin male socket also labeled "CTRL" and the same "N"
type sockets.
Any information regarding where I might purchase these connectors and any
other Info would be very much appreciated.
I have emailed Mutek a number of times over the last 2 months but no
response from them to date, their Web site also seems to be a little out
dated.
Many thanks in advance.
