Unlike last year, where I participated in ARRL and AMSAT Field Day
concurrently, I did them separately this year.? On Saturday, I worked only
satellites for AMSAT Field Day from the vicinity of my home. I never
operated from my property, only from other operating positions along my
block each optimized for specific pass orientations, all well within an 800
ft circle. All QSOs were made fully pedestrian-mobile, without recharging
any of the batteries during the Field Day period.?

Most of the FM satellites were a mess, as expected. The one daylight AO-92
L/v mode pass, 20 degrees to the west, was pretty empty, but gave me my
first QSO of the day, with WD9EWK. I chose to dual-wield two antennas rather
than attach the two together as I've normally done in the past. I strapped
the DJ-G7T radio to the handle of the 10-element 23cm EBay yagi, where the
PTT button and the VFO A knob were easily adjustable with just my left
thumb; in my right hand, I held the Arrow. This worked pretty well, and I
found it less fatiguing than having one heavier antenna.? Also made QSOs on
PO-101 and AO-85. AO-85 sounded really good, at least for that minute or so
I was on. As soon as I got the QSO, I split to go work another pass. Tried
LilacSat-2 twice, nothing heard.?

The SSB satellites seemed to have few operators on, other than QRO CW
stations. On one FO-29 pass, there were two CW stations calling CQ nearly on
top of each other and on top of a SSB station calling CQ, while most of the
passband was empty. Worked several linear passes, but made only one QSO, and
we really had to work for that one. The far-western XW-2 passes were pretty
empty.?

The packet satellites were underutilized, and could have been a great source
of points had more operators been on. Made several QSOs on FalconSat-3 and
PSAT, although only one counts for AMSAT Field Day credit. Unfortunately,
the ISS digipeater was offline.?

Worked a total of 20 passes, although for five of them the satellite was
inoperative. Total of 6 qualifying QSOs, half of them with WD9EWK. I had
planned to do several more passes that evening and a few more before sunrise
the next morning, but I decided to put this day out of its misery and
conserve my energy for Sunday.? ?

On Sunday morning, I drove to my portable operating location to operate the
rest of the Field Day period for only ARRL Field Day. Since I was going to
operate 2B1B for ARRL Field Day, I used the same operating category for my
AMSAT Field Day contacts for consistency. For the first time, I made a
full-time SO2R effort, with one radio dedicated to CW and the other
dedicated to FT8. Didn't even try SSB.? Also made one FM satellite contact
after 1800z from that operating location for the 100 pt bonus and my sole
phone contact for ARRL Field Day.?


So, how'd everyone else's Field Day go??

the linears were the opposite of empty over here on the east coast... I did
10 passes, making about 40 qsos. The center of the passband on each linear
pass was nuts, with 5-10 different stations all calling cq over one
another. I used a borrowed 910, and my handheld arrow. It was nice to have
the extra power when needed...there was one station in particular that I'm
pretty sure had to be running about 300w lol. Every time they keyed up,
literally every other station in the passband dropped out.

Easiest pass by far was EO-88, I worked N8HM and W4YY, and heard one other
station before the transponder shut off.

It was interesting to work IO-86, there was a handful of STX and FL
stations on, along with the usual south/central american ops. That was a
cool opportunity, and hopefully we will have the chance to do that next
year too. Thanks to AMSAT Ops for coordinating with the LAPANSAT team to
make that possible!

I worked satellites on Saturday only.?? I started off working under the
call sign K5RWK, the Richardson (TX) Wireless Klub, which I am a member.
I was able to get a QSO with W5RRR on AO-91.?? Having satisfied the 100-
point bonus for the club.?? I switched to my own call sign for the sake
of giving demos.?? While I could receive PO-101 fine, I couldn't get a
signal into it, so I might need to check what I programmed into my
radios.?? Of course, being Field Day, it may have just been being out-
classed, power-wise, with my hand-held radios.?? I was able to get two
QSOs on two separate passes of AO-85.?? AO-85 was having a lot of
problems with all of the use.?? It kept cutting out are coming back
after a minute or so.?? I think the drain on the batteries was too
much during each pass.?? I believe that it was worse on the second
pass.?? I'm concerned about the future of AO-85, considering it is
fully out of eclipse.?? I couldn't even get into SO-50, due to the
QRM, both unintentional and intentional.?? I believe that this was
the worst conditions on the satellites for the four years I've done
Field Day.?? That is sad, considering there were more FM satellites
available this year than ever before (AO-85, AO-91, AO-92, PO-101,
and SO-50).

Bruce,

 I have included a link to the SatPC32 manual. Scroll to the CAT Menu
section and the specific instructions start at section aa.

Hi,

The manual is your friend.  The secret sauce is to adjust your uplink on
the CAT menu until you can hear yourself, then save the uplink calibration.
Trying to tune the radio knob caused both the uplink and downlink to change
and is not how you calibrate things, but is exactly the behavior you want
(manually tuning to find someone to call, and being spot on with your
downlink too.   I do feel sorry for the folks, hundreds (thousands?),
vainly sending dots/dashes during Field Day attempting to find themselves.
The secret sauce is to do that before Field Day.  With the exception of
AO-7 which was unusually far off, all the other dozen+ satellites were
within a couple hundred hertz or less of the calibration values I use at
home on my 9100 (in a fairly stable thermal environment).

Good luck, but rest assured that SatPC32 works great controlling Doppler.

73, Bob, WB4SON

Ryan,

First of all, thanks for the QSOs during the day yesterday. Especially the
AO-92 L/V contact just after noon. I was getting concerned with being able
to make an official Field Day QSO on that pass, after working two others
who were not giving Field Day exchanges. It was also good to get you on
AO-91 and FalconSat-3 later in the afternoon.

I drove to a Forest Service day-use area at Cataract Lake, west of Williams
in northern Arizona. Northern Arizona had the best weather for Field Day
this weekend than in the past few years, with the temperatures up there
never exceeding 75F. My plans were like past years - work both HF and
satellites, and have fun doing it. Even though this site is near Williams,
and not far from the I-40 freeway, I had no data service on my mobile
phone. The phone worked for voice calls and SMS messages, so I used SMS
messages to tweet during the day. I don't have my Twitter account set up
to forward tweets to my phone, so I was unable to respond until I was in
Flagstaff for dinner last night.

It took about 2 1/2 hours to make the drive from Phoenix to Williams, and
I knew that there was an SO-50 pass coming by a few minutes after the start
of Field Day at 11am (1800 UTC). As expected, a busy pass. I heard John
K8YSE operating as K8OU through his Arizona station, and that was my first
Field Day QSO. I did not use an HT for this pass; I had my Icom IC-2730
dual-band mobile radio, jumpstart battery, and Elk log periodic in a
clearing near my site. Five watts, and even 15W, would not work on this
and the other FM satellite passes I attempted yesterday not using the 1.2
GHz band.

About an hour later, the one AO-92 pass in the L/V mode for Field Day up
there. I heard Chris VE7CEW initially, but couldn't get back to him for a
QSO. I worked W5SAT and N6NUG before landing a Field Day QSO with AI6DO. I
used my two-radio, two-antenna L/V setup like I normally use at home. It
worked well as I pointed across the lake and made QSOs, easier than last
year's Field Day when I had a smaller 5-element Yagi on top of my Alinco
DJ-G7T. I did not try to adjust my transmit power on my DJ-G7T to its low-
power setting of 300mW on the 1.2 GHz band, keeping it at 1W for the best
possible signals I could send to the satellite. And as the AO-92 pass went
away, a very high AO-91 pass came over. Back to the IC-2730, and I cut the
string holding the 1.2 GHz Yagi on my Elk, as the AO-91 pass started. Many
thanks to Carlos W7QL for a QSO near the end of that pass!

After the AO-91 pass, I set up my HF station - Elecraft K3S running on my
jumpstart battery at 50W, and a Buddipole dipole. I made some QSOs on 20m
SSB before another group of satellite passes came by - PO-101, ISS, and
then a low AO-91 pass to my west.

PO-101 had a good crowd, but not as crazy as the earlier AO-91 pass. I was
able to work Rick VE4AMU for a Field Day QSO. After that, W0IN in Missouri
called me, and I made the exchange. Shortly after these QSOs, I switched to
the ISS digipeater. Unfortunately, it was off, so no ISS packet this Field
Day. AO-91 was coming up for the west coast, and I went on there to help
anyone looking to make their Field Day satellite QSO on that satellite.
AI6DO was there, and we made a quick QSO. This won't count for me, as I
made my AO-91 QSO for points earlier, but I might be a QSO that gets
another station their 100-point bonus, or their Field Day QSO on that
satellite.

Now up to almost 2pm (2100 UTC), I started working 20m and 40m SSB, until
a nice FalconSat-3 pass an hour later. I logged a couple of packet QSOs
with AI6DO and Brad W5SAT in Las Vegas on that FalconSat-3 pass. This time,
W5SAT was ready with a Field Day exchange in the APRS message I received
from him. I had two more FalconSat-3 passes that I worked, just before 5pm
(0000 UTC) and 6.30pm (0130 UTC), with a single QSO on each of those
passes.

I tried FO-29 at 5.30pm (0030 UTC), but one station was overpowering the
transponder really bad. After a few minutes, I gave up on this pass.
I didn't bother to try other SSB passes since it was getting late, and I
needed to ensure I left the site by 8pm (0300 UTC) before the gate was
locked. I overlooked the NO-84 pass just after 6pm (0100 UTC), a mistake on
my part, since packet QSOs using APRS messages have been good for me in
past Field Days. I stayed out there to copy the ARRL's W1AW bulletin on 20m
SSB just before 7pm (0200 UTC), and then I wrapped up my Field Day effort.
I went to Flagstaff to get some dinner, then drove home after that.

During the afternoon, I would periodically check the 10m and 6m bands for
activity. Nothing was heard on those bands most of the day, but a little
before 5pm (0000 UTC) W3AO - a group that loves to put lots of transmitters
on the air for Field Days - was barely coming out of the noise. After 2 or
3 minutes of back-and-forth to get information exchanged, I made a QSO with
W3AO. This was my first Field Day QSO on 10m in a few years, and worth the
extra effort to make the QSO. :-)

I still need to get my logs prepared for both ARRL and AMSAT Field Days,
as there will be some satellite QSOs in my log that won't count for
points in each event. My Field Day QSOs have already been uploaded to
Logbook of the World. If anyone wants a QSL card for a QSO from yesterday,
please e-mail me directly with the QSO details. I will be happy to send a
card, without first receiving a card or SASE from you.

I have an old 5400B that I use at a summer location. I use another old fox
delta serial control interface that emulate GS-232. It has developed a
strange problem with the AZ rotor that seems to occur when it reaches the
extreme S (past E) where  it tends to freeze. The only way to unfreeze it
and gain control again is to shut the control box off for a short time and
then it will run fine manually or under control by SATPC32. I?m guessing
there may be some thermal device inside the rotor itself that is exceeding
a limit and needs to cool down. I?d love to hear some suggestions on what
the problem might be.

Tnx

 Thanks for the QSOs yesterday, Patrick, especially that tough western AO-91
pass!? Also, thanks for the reminder about W5SAT. I do have a message packet
from him with his Field Day exchange on my D72 from that first FalconSat-3
pass, so I have one more QSO (and 3 more points) than I had thought.?

Thanks and 73, Ryan AI6DO

 Ryan,

First of all, thanks for the QSOs during the day yesterday. Especially the
AO-92 L/V contact just after noon. I was getting concerned with being able
to make an official Field Day QSO on that pass, after working two others
who were not giving Field Day exchanges. It was also good to get you on
AO-91 and FalconSat-3 later in the afternoon.

I drove to a Forest Service day-use area at Cataract Lake, west of Williams
in northern Arizona. Northern Arizona had the best weather for Field Day
this weekend than in the past few years, with the temperatures up there
never exceeding 75F. My plans were like past years - work both HF and
satellites, and have fun doing it. Even though this site is near Williams,
and not far from the I-40 freeway, I had no data service on my mobile
phone. The phone worked for voice calls and SMS messages, so I used SMS
messages to tweet during the day. I don't have my Twitter account set up
to forward tweets to my phone, so I was unable to respond until I was in
Flagstaff for dinner last night.

It took about 2 1/2 hours to make the drive from Phoenix to Williams, and
I knew that there was an SO-50 pass coming by a few minutes after the start
of Field Day at 11am (1800 UTC). As expected, a busy pass. I heard John
K8YSE operating as K8OU through his Arizona station, and that was my first
Field Day QSO. I did not use an HT for this pass; I had my Icom IC-2730
dual-band mobile radio, jumpstart battery, and Elk log periodic in a
clearing near my site. Five watts, and even 15W, would not work on this
and the other FM satellite passes I attempted yesterday not using the 1.2
GHz band.

About an hour later, the one AO-92 pass in the L/V mode for Field Day up
there. I heard Chris VE7CEW initially, but couldn't get back to him for a
QSO. I worked W5SAT and N6NUG before landing a Field Day QSO with AI6DO. I
used my two-radio, two-antenna L/V setup like I normally use at home. It
worked well as I pointed across the lake and made QSOs, easier than last
year's Field Day when I had a smaller 5-element Yagi on top of my Alinco
DJ-G7T. I did not try to adjust my transmit power on my DJ-G7T to its low-
power setting of 300mW on the 1.2 GHz band, keeping it at 1W for the best
possible signals I could send to the satellite. And as the AO-92 pass went
away, a very high AO-91 pass came over. Back to the IC-2730, and I cut the
string holding the 1.2 GHz Yagi on my Elk, as the AO-91 pass started. Many
thanks to Carlos W7QL for a QSO near the end of that pass!

After the AO-91 pass, I set up my HF station - Elecraft K3S running on my
jumpstart battery at 50W, and a Buddipole dipole. I made some QSOs on 20m
SSB before another group of satellite passes came by - PO-101, ISS, and
then a low AO-91 pass to my west.

PO-101 had a good crowd, but not as crazy as the earlier AO-91 pass. I was
able to work Rick VE4AMU for a Field Day QSO. After that, W0IN in Missouri
called me, and I made the exchange. Shortly after these QSOs, I switched to
the ISS digipeater. Unfortunately, it was off, so no ISS packet this Field
Day. AO-91 was coming up for the west coast, and I went on there to help
anyone looking to make their Field Day satellite QSO on that satellite.
AI6DO was there, and we made a quick QSO. This won't count for me, as I
made my AO-91 QSO for points earlier, but I might be a QSO that gets
another station their 100-point bonus, or their Field Day QSO on that
satellite.

Now up to almost 2pm (2100 UTC), I started working 20m and 40m SSB, until
a nice FalconSat-3 pass an hour later. I logged a couple of packet QSOs
with AI6DO and Brad W5SAT in Las Vegas on that FalconSat-3 pass. This time,
W5SAT was ready with a Field Day exchange in the APRS message I received
from him. I had two more FalconSat-3 passes that I worked, just before 5pm
(0000 UTC) and 6.30pm (0130 UTC), with a single QSO on each of those
passes.

I tried FO-29 at 5.30pm (0030 UTC), but one station was overpowering the
transponder really bad. After a few minutes, I gave up on this pass.
I didn't bother to try other SSB passes since it was getting late, and I
needed to ensure I left the site by 8pm (0300 UTC) before the gate was
locked. I overlooked the NO-84 pass just after 6pm (0100 UTC), a mistake on
my part, since packet QSOs using APRS messages have been good for me in
past Field Days. I stayed out there to copy the ARRL's W1AW bulletin on 20m
SSB just before 7pm (0200 UTC), and then I wrapped up my Field Day effort.
I went to Flagstaff to get some dinner, then drove home after that.

During the afternoon, I would periodically check the 10m and 6m bands for
activity. Nothing was heard on those bands most of the day, but a little
before 5pm (0000 UTC) W3AO - a group that loves to put lots of transmitters
on the air for Field Days - was barely coming out of the noise. After 2 or
3 minutes of back-and-forth to get information exchanged, I made a QSO with
W3AO. This was my first Field Day QSO on 10m in a few years, and worth the
extra effort to make the QSO. :-)

I still need to get my logs prepared for both ARRL and AMSAT Field Days,
as there will be some satellite QSOs in my log that won't count for
points in each event. My Field Day QSOs have already been uploaded to
Logbook of the World. If anyone wants a QSL card for a QSO from yesterday,
please e-mail me directly with the QSO details. I will be happy to send a

On the AMSAT FM Satellite Frequency Summary it lists the
up-link frequency for PO-101 (Diwata-2) as 437.500 MHz.
On the PHL Microsat website, the up-link frequency is
listed as 437.7 MHz.?? Which is correct??? I tried to
work PO-101 during Field Day yesterday and had no
success getting in with my radio set to 437.500 MHz,
and Doppler-shift adjusted near values.?? Of course,
being Field Day, I could have just been 'out-gunned'.
I do wonder, though.

73,
