What did you think of Pacificon
5
I would like to hear other opinions of Pacificon. Here are my thoughts in no particular order of importance. 1. Crowd was down. If we want to keep having a big convention in the bay area, we must support it by attending and getting others to attend. 2. Talk selection was poor. We need better speakers with a wider variety of subjects. I'm sure there are 4 or 5 members of this group who could give a great talk on building, operating portable, contesting, chasing dx, qrp. We need to step up! 3. Qrp sessions went well, but definitely need to improve. We have plans to do that. 4. Vendors. They definitely need more vendors. No Icom, no Kenwood??? It was good to see Elecraft, Yaesu and Flex. Where was Hexbeam, Buddipole, and Stepper IR? 5. It was great to see friends although I missed Joy and didn't get to meet Connie. I did see Barry, Dave C., Paul, Bob, Rex, Pete, and Hiroki from this list.. So there were 10 that I know of from this list who attended, good job. Ok, your turn

Silenzio, Per Favore
7
The RF noise level at my QTH has me going berzerko... at times I am seeing S9+15 dB on 20 and 15M, though it sometimes settles down to S6-7 during the wee hours. Nearly S9 at the moment (these readings on my Kenwood TS590SG). The neighbor's new solar/battery setup cannot be helping. My addiction to magloops has me thinking about W6LVP's receive loop. Does anyone have experience with it? See W6LVP.com and https://www.eham.net/reviews/view-product?id=13215. Thanks, and best, --David KM6RI

Comet sighting.
2
Have you guys seen the comet? I went out just after dark with binoculars on Sunday. West SW. About 40 degrees elevation. There was a faint white stripe about a degree long. I understand that in following nights, the comet will get further from the sun. The Good news: it will be in a darker part of the sky. The Bad news: the comet will get fainter.

Good to see many of you in San Ramon. If you are at Pacificon, check WAZE or G Maps or ??? to find alternate routes before you start. Good luck,

Hiroki's article in QRP ARCI magazine

Just arrived today, and looks great! Congratulations! 73, Eric NF6S ex WD6DBM ?

Something is in the air...
Hey folks, I think propagation is likely pretty good right now. On the ship today, 10MHz and 15MHz were booming. In the car, lots of FM BC DX, from Sac and north valley, KCHO. Car on 680 S in San Remote. Right now I don't have a chance to operate, I hope someone does. Cliff K6CLS CM97 right now

Band Pass Filters
12
Very interesting postings. But are we using a cannon to kill a fly? These filters are all good and do the job I am sure. But they are expensive, and handle hundreds of Watts. Joy runs qrp. A KX2 I believe, and she is running 10 W at the most. I don't think I have ever seen anyone out at Baylands who wasn't running qrp. Correct me if I am wrong. So we have one qrp station on 20 meters who wants to avoid interference from other stations on other bands who are also running qrp. Why does she need a filter that will hand hundreds of Watts and is very expensive? One of the things that attracted me to qrp was that you don't need a lot of money for equipment ((at least you didn't before Elecraft came on the scene) and I love and have their gear). It's easy to build a band pass filter in an altoids tin. Hiroki how about you and I build one and see how it works. Build it and test it empirically. Is the challenge accepted? The rest of you are welcome to try too. I love this group because they actually do ham radio. Doug

IC 7300 Clock Battery

How many of us have a 7300 with the clock battery run down and time constantly needs setting. Here is a nice solution by installing a rechargeable battery LR 2032 and a 1K resistor. IC7300 extra clock battery (pa0fri.com) IC7300 extra clock battery Dave W6VYC

S tuner by PA0FRI
This is the original source of the S Tuner design that was in the FARS homebrew contest. The unit at FARS was nicely built in a non-conductive wooden/plexiglass box. He claimed this tuner architecture was more efficient than the Palsar tuner. S-Match universal antenna tuner (xs4all.nl) Dave W6VYC

Dunstar Filters

These are the bandpass filters that have been used for years. Don't know if you can find them anymore. They are coupled resonator type filters using air core inductors. If you really want, you can make your own. See attached.

? Jeff¡¯s call sign, AJ6WX, was corrected in the final printed version. The mag loop has been modified to allow 20m operation by adding an additional 50pF butterfly variable capacitor. Hiroki AH6CY

RadCom October Issue

Hiroki strikes again this month with an article about his mag loop remote controller. He credits Jeff Reagan for the dual stepper motor idea. He also credits 6 others for help preparing the article. I give Hiroki credit for being a very creative inventor. Bob KF6ABC

Interstation interference book
8
Joy was asking about how to use a bandpass filter to limit interference at the Baylands. I don't recommend that you buy the filter. It is difficult to build analog filters good enough to limit interference. There are some good commercial filters that have been used during field events (InRad triplexer). Check out the filters that are used at Pacificon. I found this interesting book that might help. see attached. Dave W6VYC
