Re: IARU HF Championship 2009
Congrats Nick. QRP rules!
Between my travels and work on the B29 radio deck project I have not done any field operations for a long time. I understand 15 and 24m have come back. You may have seen a posting by my friend re his QSO between PY1 and KH6 with a mag loop.
On a different note, I happened to discovered a little but well curated museum called the National Electronics Museum near the Baltimore airport. It is well worth a visit if you are in the Washington area.?
I am in Williamstown attending a wedding of a friend's daughter. I saw a group of QRPers operating at the water's edge in Jamestown.
Headed for DC, NYC es BOS from here. ?Back in CA on 11/2.

Re: More on Pacificon Zombie Walk/QRP Activities
Oh, I really wish I could attend these events, even though I have never tried operating in foot mode. It would be great if someone here in the group could provide a synopsis of what happened during these events. Dave/W6DLF --- In QRPops@..., eric norris <gliderboy1955@...> wrote:

Hi Gang,
Finally, I can bring you up-to-date on HFPack fun at Pacificon 2010.
On Friday, 10/15/2010 we are having a joint HFPack/NorCal QRP dinner.
WHEN? Meet in the hotel lobby near the revolving door at 6:15PM.
WHERE? The Pasta Pomodoro Restaurant, which is just a short walk
down to the small shopping mall next to the Marriott. A Target
Store should be on your right, and the restaurant on the left.
They plan to have tables setup for the HFPack Group.
Here is the info...
Pasta Pomodoro
146 Sunset Dr
San Ramon, CA 94583-2340
(925) 867-1407
The restaurant manager said they cannot do separate checks unless
we break up into groups of three at the table. Credit cards are ok, but cash is
preferred for a group bill. Be sure to write down what you had ordered, and how
much it was. The food is good, and the place is within walking distance. If you
must drive, there is plenty of parking space in the mall.
On Saturday,Oct. 16th we have three different events. (Check the HFPack Button
at www.pacificon. org, and keep your Pacificon flyer as a reminder for forum
room locations).
HFPACK 101 BEGINNER'S FORUM at 9:00AM .. Hosted by Glenn WB6W
Don't know a dragging counterpoise from a HFPack Zombie? Huh? Whatzat?
This beginner's forum is for YOU!
HFPACK'S 1Oth ANNIVERSARY FORUM at 1:00PM.. Hosted by Ken WB6MLC
Go back in time with Budd, W3FF. Hear about the early days when
HFPack was not taken seriously at conventions. See the very first
Buddipole! Hear Harry W6DXO take us back to the future with his
/PM SATPack setup. Wayne from Elecraft also has something very important to
share, so don't miss him.
HFPack ZOMBIE/QRP NITE at 7:30PM to ? ..Hosted by the HFPack Zombies!
WHERE?: The evening activities will be held in Forum rooms F,G,and H.
The HFPack Zombie/QRP Nite will have the following INDOOR, and OUTDOOR events:
"IN THE ROOM" ZOMBIE/QRP CW QSO Party... (starts around 7:45pm)
Yes.. you read that right! Bring your favorite battery powered portable rig, or
your backpack,Keyer, a dummy load plus clip leads, or a portable antenna and
some duct tape to setup a Zombie QRP station ANYWHERE inside the room. For 10-15
minutes after signing in, and getting organized, you will work as many CW
stations as possible. You must keep your own scratch paper log. The station with
the most Q's wins a door prize.
When you are done, keep your station intact for the next event..
QRP SHOW and TELL NO TALES...
All in the room and visiting Zombies can now feel free to check out the
stations, or anything else that is on display. If you have something to show,
bring it. Is it alive? Tell us! QRP vendors
will be lurking in the shadows if they can crawl in.
HANGING EYEBALL Meet and Greet.(up to 10:30pm or beyond for niteowls)
The Zombie / QRP Nite was intended as a place for all QRP fans, HFPackers, and
NorCal QRP members to hang out and relax.
Get to know all of the local Ghouls and Zombies staggering around the room.
OUTDOOR ZOMBIE WALK.... Starts at 9:30PM until 11:00PM PDST.
The HFPack Zombie Walk is back, and this time we want everyone to
show up and participate. Bring whatever rig you have, a decent battery, portable
backpack plus antenna, and check into the WALKING
ZOMBIE NET on 7185.00 LSB. Your pack does not have to be fancy,or complicated.
Toss your FT-817, KX-1, Homebrewed special, or a TS-2000
into a knapsack and go for it. WE can operate mixed mode if necessary.
HFPackers in the rest of the country should give the Walking Zombies a call. If
the freq is busy, we can move to 7200.00 LSB if necessary.
Meanwhile, Zombies who must remain INDOORS will have a Zombie Patrol
Station setup in the Zombie /QRP Nite room. Those who chose to
stay inside can talk to a live(?) HFpack Zombie staggering about the
hotel grounds. Call CQ HFPack Zombies on 7.185 LSB. Hope to hear all of you on
the air.
Ok.. the above is the latest. We expect to have special HFPack Celebrities
appearing at Pacificon 2010. 3 of them standing together have 10 legs. Give up?
Steve WG0AT the Goat Guy and 2 HFPack goats
will be outside trimming the lawn for the Marriott. Will Bonnie KQ6XA make an
appearance this year? There is only one way to find out!
See ya all at Pacificon 2010...

HFPack Activities at Pacificon 2010 at the San Ramon CA Marriott 10/

Mon Oct?11,?2010 4:10?pm (PDT)
Hi again gang,
I forgot to mention up front that Pacificon 2010 is being held this
year at the San Ramon, CA Marriott. Pacificon Attendees should not have to pay
any parking fees. Confirmation for this can be found at the Pacificon.org
website.
The forums and exhibits at Pacificon 2010 are looking good, and there should be
something of interest for everyone.
Now.. for some more updates on the HFPack Zombie/QRP Nite.
I mentioned that for the Zombie Walk you can bring any rig that will work no
matter how heavy, or simple it may be. Carry your rig inside a shopping bag if
you must. Be creative! One more thing, since this is a ZOMBIE WALK, feel free to
appear in makeup and/or costume.
It is ok to Zombify yourself in any way you can to fit it and look normal. Don't
worry if folks stare at you. They are probably admiring your backpacks with tall
antennas swinging around as you walk.
This time of the year there are many Zombie Walks taking place all over the
country. We just happen to be Radio Zombies who like to feed on RF in the dead
of nite.
For the IN THE ROOM Zombie/QRP CW QSO Party, I am sorry if some of you cannot do
CW as well as you would like. Grab the nearest Zombie in the room who is CW
proficient, and ask if they can decode or send for you. Next year we may have a
Phone QSO party segment if enough folks demand it. BTW, makeup to zombify
yourselves is also optional. Since Halloween is just around the corner, go ahead
and have some fun.
The NorCal Zombie Shuffle CW QSO party is always held on Oct 31st, so
we are paying homage to these folks. While you are in the room,
you will learn about the infamous Area 51 Zombie Badge created by
NorCal. No radio Zombie should leave the crypt without it!
So on October 16th at 7:30PM, bring your Bloodypoles, and RIP-1 screwdriver
antennas and join the HFPack Zombies for a nite of fun.
Who knows? Steve WG0AT and some Zombie Goats might make an appearance.

Pacificon ZOMBIE WALK IS BACK!
Dear QRPopsters:
I just returned from QRPacificon with some good news.? The ZOMBIE WALK is back!?
It will happen probably at 9:30pm Saturday night, on 40m SSB at Pacificon.? So
kludge up a portable antenna and rig, and JOIN US!? News will be forthcoming
from the HFpack reflector in the next day or two.
There was some talk about my being appointed Head Zombie.? Yeah, that's a
stretch.?
I've abandoned work on my QRO TS-480 backpack as the project weight climbed
above 40 lbs and an old weightlifting knee injury has resurfaced in my new
curling career.? I am now working on a shoulder-holster K1, and a camera
bag/ALICE backpack FT817 setup that will be much lighter.?
I hope to see you at Pacificon.
72,? Eric WD6DBM

new two-way communication system
| I saw the sign (attached photo) on my walk the other day. We have all experienced plug-and-play devices turning into plug-and-pray things. The minister of this church may be onto something. Only in?Silicon Valley!
I hope your day is turning out to be as god as mine.

Backpack frame for QRPer on eBay
I was browsing the eBay site for my Enola Gay radio project and happen to come across this one. If you happen to be looking for a suitable backpack frame to mount your QRP gears, this is exactly the one I have been using and find it very useable. It is light and sturdy. The aluminum frame allows you to drill holes easily to mount antenna, batteries, etc. ?You may be able to get it cheap.?

Hiro's QRPops Eye Ball QSO Party
Hiro,
Anke and I had a great time visiting the home QTH. Good to see everybody and thanks for the great food. I particularly enjoyed seeing your glow in the dark equipment and your interesting collection leading up to a B-29 radio deck.
Hope to see you soon, 73/72 ? Dave? W6VYC

| Hiro,
Thank you for putting on such a pleasant Op at your home. The BBQ was delicious and it was enjoyable to just eat, sit around, and talk with our fellow enthusiasts.?
When I left and walked out to my car, there was a red Prius parked next to the Mini with the license plate 'QRP?CAR'. Nice way to finish off the visit.

| Folks,
After everyone left today I turned on my FT817?about 5pm,?connected to the mag loop all still on my deck. 17 was somewhat open with a few faint signals. Suddenly one loud signal KB0 in Missouri boomed in with 59+. It was Myles whom I met a couple of times before from the Bayshore preserve location. I waited for him to finish the QSO with a W4 (whom I couldn't hear) and I called him with all of 2.5 wtts. He came back to me and we had about 10 minutes QSO. I was 42 or so with QSB at his end. Sure he was running 800 wtts into a 2 element delta loop up at 80 feet. The moral, though, is simply that if the other station has big ears (many QROs don't; they only have big mouths) and experienced enough to listen for QRPs, and, of course, helped with a lucky timing, even a misery 2.5 wtts can get thru. Of course, you kew
that
already.
I had fun having you all. Thanks also to the XYLs and one harmonic who put up with our hobby. I hope this will become our annual event. The condx for the next 5 years plus should be better than this year.

Hiro, thanks for our very pleasant get-together yesterday. Eating, relaxing, and talking together on your deck was beautiful.
Thanks also for finding a creative way for me to have my first SSB contact.
Hope to see you soon,
Take good care,

I'm working on building and all-smt SDR rx design with the objective of size reduction. (Nothing new here, but an interesting challenge) The design/manufacturing process is interesting and your experiences/notes are very valuable.
I can't agree more on your closing perspective of "not to put off building new projects because of some "barrier to entry"?
I've had more fun recently, building things, than in the 15 years of ham radio before. We're certainly fortunate to be living in exciting times for rf tech development - given that a $10 SDR homebrew construction can now achieve the same level of performance of professional grade equipment - costing $1000s.
Being new to PCB manufacturing, I find the process of
parts-selection a little cumbersome.
Especially the minimum-buy constraints for most of the SMT parts.
What is the trick to not have to buy 500 lots and to have the PCB layout dictate the parts selection and not the other way around?
Wonder if you have some tips on parts-selection process when using digi-key (or another vendor)?
Have you worked with any of the FPGA dev boards?
The Xilinx board looks like a decent starting point?

Wonder if you have some tips on parts-selection process when using digi-key (or another vendor)?
Have you worked with any of the FPGA dev boards?
The Xilinx board looks like a decent starting point?

Re: Introducing Ward Harriman, AE6TY
For those interested in how SDR tech is revolutionizing the comms landscape, I found these write-ups really interesting read:

I can't agree more on your closing perspective of "not to put off building new projects because of some "barrier to entry"
I've had more fun recently, building things, than in the 15 years of ham radio before. We're certainly fortunate to be living in exciting times for rf tech development - given that a $10 SDR homebrew construction can now achieve the same level of performance of professional grade equipment - costing $1000s.
Being new to PCB manufacturing, I find the process of parts-selection a little cumbersome.

Ward,
Great articles on SDR. I would love to talk to you about your project. I have a Tony Parks SDR receiver that I have been experimenting with using a E-MU sound card and Rocky software. It would be interesting to see if a portable QRP rig could be built using a DSP chip and a small uP, a la NUE-PSK modem but with SSB and other modes.

Dear QRPopsters:
I'm introducing Ward Harriman, AE6TY, to the group.?? If his name is familiar it
may be because you have read his three-part article in QRP Quarterly, "Making a
Software-Defined Radio for the QRP Enthusiast."?? The final installment is in the
current issue.
Ward also enjoys tinkering with antennas and other QRP equipment.?? He's only
been a ham for a few years but he is clearly making up for lost time.??
