1735Z pass. Good up and downlink on a 5 degrees pass to the east and
northeast. No one to work.
Next pass is 1916Z. I it is 78 degrees max ele for us to the west.
We will try to work as many as we can. As a reminder it is much easier
for me to find you in the passband if you just transmit on 145.985. I
am tuning +- 10 or so from my downlink and I can follow your Doppler
without difficulty.
We may try the 2106Z pass tonight but the last one of these skimmers to
the west there was no one on to work.
We have had a great and long opening on 6 meters today all the way to
Colo. Ken worked a couple hundred on CW and some SSB. We think it was
enhanced by tropo here - getting us into the Es spot up near Puerto Rico.
On HF we got the RTTY going after some struggles and it is now a total
zoo on 14.082. We will probably keep RTTY going today and tomorrow.
Tomorrow is our last day of operating.

Hey Jim,
Just to clarify are you wanting us to transmit on 145.985? or 145.925 as
the previous passes were.
Back home now, so hope to catch you on this next pass.. Thanks and 73!

Message-ID: <C3D012C7-2C64-4035-97C2-8C8122F78548@xxxxx.xxx>
Content-Type: text/plain; charset=us-ascii
Hello, AMSAT-BB:
Recently I made a trip to CN74/CN75 and CN84. Here is my report.
A business trip to the Portland, Oregon area (CN85) over the week of June 6,
2015 through June 10, 2015 gave me and my XYL Karen an opportunity to visit
her family. They live in CN84, and the family's favorite Indian Casino is
very near the gridline of CN74/CN75. I saw an opportunity!
Previous remote trips have involved an Icom IC-W32A and an Arrow. This was
effective when there were more FM satellites.
In the time since I have accumulated some gear compatible with linear
satellite work. This is what I took with me:
Uplink:
Yaesu FT-897D with two internal battery packs and W4RT fast charger.
Downlink:
Yaesu FT-817ND with expanded internal battery pack and stock charger.
Antenna:
Arrow II 146/437 with 10BP module removed.
Cables:
Two 10-foot runs of high-quality RG-58, one for VHF and the other for UHF.
Other equipment:
Sony ICD-UX70 MP3 Recorder wired inline with FT-817ND and
Heil Traveler Dual headset.
Tripod purchased at a thrift store.
Garmin 72H GPS using WGS-84 data to verify location.
Audio cable splitter to allow for remote auditing.
Apple iPhone 6 Plus running GoSatWatch 3.2 for pass timing and visualization.
I negotiated with the family to schedule our traditional "casino crawl"
visit around a low eastern pass of FO-29. The normal extemporaneous nature
of scheduling these visits did not allow much advance notification of the
operation, but were were able to send an e-mail to this list and broadcast a
notification on Twitter a couple hours in advance.
DXpedition team members included myself, XYL Karen, and XYL's brother Jason.
We located the grid line in the parking lot of a nearby RV park.
Here is a diagram of our operating location:
Here is a verification of our location:
Our XYL and her brother were especially accommodating in precisely locating
the vehicle at the 45.00000 degree line, and changed the parking spot of our
vehicle four times to get it just right. In accordance with VUCC rules, the
Transmitter must be at the proper location, and it certainly was.
All equipment fit inside a carefully packed and padded standard-sized
airline carry-on wheeled bag. It was necessary to partially break down the
Arrow, but assembly was quickly accomplished.
We set up the tripod, wired in the antenna, situated the radios on the open
back hatch of the vehicle, and wired up the audio cables. Jason-Brother
monitored the audio and XYL Karen took photos of the operation.
After the pass concluded, we disassembled and packed all equipment, and
proceeded to give our semi-annual contribution to the Confederated Tribes of
Siletz Indians.
In all, we made 6 contacts with the following operators:
W0DHB
N8RO
W7LRD
AJ9K
K7ULS
KF7PCL
The use of the MP3 recorder was extremely valuable to clarify callsigns
after the QSO.
Post-Production work:
We use Microsoft Excel to log each pass worked along with its parameters.
We use Audacity 2.0.5 for decoding and processing the MP3 files.
We use Ham Radio Deluxe Logbook 6.2.10.377 for storing QSO records and TQSL
2.0.3 to upload QSLs to Log Of The World.
To post-process the DXpedition, we performed the following steps:
1. Created a new profile in TQSL named KL7CN_W7-CN74xx
2. Created a new log in HRD Logbook named KL7CN_W7-CN74xx-SAT.
3. Created a new My Station entry in HRD Logbook named KL7CN_W7-CN74xx.
4. Copied the MP3 file from the recorder to a special Dropbox folder.
5. Renamed the file to 20150612T2217Z KL7CN_W7 CN74xx FO-29.mp3 for ease of
location later.
6. Made an entry for the pass in the Excel spreadsheet containing all the
pass parameters as generated by GoSatWatch.
7. Listened to each QSO in the MP3 file using Audacity.
8. Made two entries for each QSO -- 1 per grid -- in HRD. Note: HRD has
several issues that add extra work for satellite operators. Notably, the
Band RX and Freq RX fields must be set manually. Have not been able to
convince HRD publisher to fix these issues despite several passionate
requests; especially annoying as these fields were previously available in
HRD 5.x era.
9. Uploaded QSOs to LotW after double-checking the location setting.
Left to do:
10. Generate printed QSL template in MS Word based on another template
previously used for these DXpeditions.
11. Mail QSLs to happy recipients.
CN84 activity:
Repeated these steps for activity in CN84 (at Jason-Brother's house),
operating on two passes. Chose early low eastern passes for the benefit of
east coast operators.
Changes for next time:
1. Obtain a lighter tripod, perhaps a telescope tripod?
2. Establish counter-weight for Arrow, as axial rotation is quite important
for resolving satellite fading issues. Sometimes the Arrow would twist off
in an odd direction when it was axially rotated. (Not sure if telescope
tripods are rotatable axially like camera tripods.)
3. Obtain a powered speaker for audiences.
4. Locate or build some sort of an audio mixer that would allow uplink audio
to be mixed in with downlink recording, as downlink recordings of uplink are
not always especially audible.
5. Label the base of each element of Arrow for even faster assembly.
6. Obtain preamps, possibly.
7. Consider alternative logging software.
Keepers for next time:
1. Although heavy as sin, the extra power of the FT-897D is quite valuable
especially on SO-50. Will continue with this.
2. The Garmin 72H GPS is quite sufficient to prove location.
3. The MP3 Audio Recorder.
4. Taking all the gear as a carry-on in the airplane.
Notes on passing rather odd-looking equipment through the American TSA:
Although the disassembled Arrow and dense batteries of the two transceivers
must surely look like a threat or IED in the X-Ray, no one at the TSA looked
twice or asked about them. However, my body was inspected quite closely and
thoroughly, as extra adipose tissue is surely suspect as improvised plastic
explosives.
Possible next operation:
The grid line of CN94/DN04 is a three-hour drive from Jason-Brother's house
in CN84. If overnight accommodations can be arranged, it may be possible to
activate these relatively rare grids with the support of the family. There
are no Indian Casinos in this area, but it is a beautiful drive.
Thanks for reading! Looking forward the next Grid DXpedition!

Wow,
If I read that correctly the charts are showing almost 20 dB or more higher
noisefloor measurements on VHF than UHF. That is a huge difference.
But in the text they say it is "30 dB" higher. I haven?t had time to dig
out why the say that, but at a first cut, this shows the 9 dB link advantage
of VHF over UHF vanishes at the ground station trying to hear a weak signal
in the noise...
I did not have time to thouroughly digest the report. SO may have jumped
to the wrong conclusion based on the details.

I'm hoping someone can help clear this up! Not sure what happened, but when
I start SatPC32 the "Countdown" window no longer appears. I've tried
reselecting it from the ACCY menu, also did a reinstallation of the program.
Must be something simple I have overlooked but seem at a dead end here.
Any advice or suggestions would be most welcome!

Since SatPC32 started speaking German a few days ago, I take it that
Light Sail has reentered. So I have been listening for BricSAT NO-83,
but I do not hear, see or display any type of data.
I have been monitoring 437.975 MHz FM for 9K6 Packet. Is it supposed to
be repeating 1K2 data from the uplink of 145.825FM as well as telemetry
??? It should be able to hear NO-84 quit well as a source.
Or is the feature not turned on ?
With the two satellites in view of each other, the PSK-31 transponder
would pose a conflict. I would not expect that transponder to be on.
