A good friend of many of the WETNET gang, Richard N7RIG, passed away

this afternoon after fighting cancer for the last few months.


Richard was known to many as 'Santa Claus' and the guy who had the

farmland big enough for us to erect the full-size 20M rhombic on

field day.


He will be missed.


Memorial service details to follow as soon as I have them.


Don’t walk behind me; I may not lead.

Don’t walk in front of me; I may not follow.

Just walk beside me and be my friend. — Albert Camus


Richard walked with all of us.

Where does the WETNET gang hangout?

I've been getting a number of requests lately asking for a list of frequencies where at least some of the wetnet gang can be found. 

I'll get around to adding a list to the FAQ but in the meantime here's the current list.

      Location                          Frequency               PL

  • Olympia                        224.08/ -1.6Mhz    103.5
  • Central Puget Sound    224.58/ -1.6Mhz    103.5
  • North Puget Sound       224.78/ -1.6Mhz    103.5
  • Central Puget Sound    441.950/ +5Mhz     97.4

All four machines are linked together (441.950 is the hub machine)   220Mhz is the preferred band although we won't scream if you come in on 441.950.

The Continuing Implosion of the Cellular Phone Industry

While it's not news that over the past couple of decades, the cellular phone business has slowly changed from an exotic, elite high-tech, high-priced business into a cut-throat melee similar to the present day PC business this chart shows the dramatic fall of Nokia and rise of Apple. What's even more interesting is the item in the comments explaining that Tim Cook, Apple's COO, is an (evil) genius that has cemented Apple's place in the computer and cell phone industries not through innovation, low-costs, or other traditional paths, but by cornering the supply of critical components and ensuring that competitors are unable to obtain them:


The real story about Apple isn't the innovation or design of Steve Jobs or Jony Ive, it's that Tim Cook is becoming the greatest monopsonist of modern times. He is to computing and electronics what Walmart is to general stores; a weapon that sucks the life out of everything around it. The reason you can't get a high-end lightweight laptop from anyone other than Apple, or the reason that Macbook Air competitors on the PC side are rather expensive isn't because HP or Lenovo are stupid, it's because Apple cornered Foxconn's assembly line for making metal computer cases. Tim Cook's business skills in completely cornering supply chains is great for Apple's current customers while it lasts, but it is not sustainable for the broader market and it will cause more harm than good if it continues, in the form of less choice and less product at higher prices.

HPSDR Comes to Professional Radio Astronomy

Some people at UC Berkeley have been doing some interesting work with SDR that kind of mirrors what's been going on in the amateur SDR community: They have concluded that building custom systems takes too long and costs too much money, so they've started using the same kinds of components and techniques that the amateur HPSDR community is using.  Check their web site at https://casper.berkeley.edu/

As an example of the kind of things they are doing, consider a 44 receiver array with beamforming and correlation centered at ~1400 MHz with a 200 MHz bandwidth! This takes a _lot_ of processing power, but the compared with what can be done with a single receiver, the contrast is dramatic. To me, this validates the approach of using high-speed direct ADCs and large FPGAs performing the DSP "heavy lifting". I also notice that they are using the Polyphase FFT filtering being championed by Frank Brickle and Robert McGwier for the AMSAT DttSP project.

Field Day wrapup

WOW, what a georgeous weekend for FieldDay this year.  It's been years since we've had weather this good.IMG_0489.JPG

While Friday was a bit on the cloudy side that made it perfect for putting up antenna's.  Richard (n7rig), Tor (ae7ev), Curt (we7u) and I (n7ipb) put up Richards new HF vertical, the forty foot mast for the dipoles and the operations tent.

Considering it was only the four of us (and Richard left early to attend n0fpf's wedding open house) we did pretty well.

Then it was off for beer and food at the Skagit River Brewery.

It's Field Day time again

Once again the WETNET gang will be participating in  ARRL Field Day from the QTH of N7RIG in the beautiful Skagit valley.


Tlhis year, unlike years past we're not doing a special antenna project nor are we putting up one of our previous big antenna's.  No Bruce array,  no 20M rhombic.

Instead we'll be keeping it simple. 

  • One Titan-DX multi-band vertical (destined to eventually become N7RIG's permanent HF antenna)
  • One 160/80/40 dipole and G5RV on a single mast
  • One 6-meter quad.

SeaPac 2011

Our annual outing to the SEAPAC convention in Seaside Oregon is over for this year.  Once again a fun time was had by all with  something like a dozen and a half of the Wetnet gang there as well as countless other acquaitences  there was no lack of activity.

This year Peter (wa7fus) provided a portable 224.22 repeater and ran it from his hotel room.  It made staying in contact with everyone extremely easy and avoided the hastle of finding a clear simplex frequency for our use.

I didn't win anything but I did pick up some clamp-on ferrite filters to see if I can kill the two meter interference in my car and maybe make an attempt at eliminating the 144.39Mhz interference from my Clear modem at home.  I'm not holding my breath but it would be nice not to have to relocate the APRS antenna.

Richard (n7rig) was the real winner this weekend, getting two small prizes ($10 at the booth of the guy with all the soldering equip. and a free pizza at a local place).  

But the biggie was when he came away with a Yaesu VX-3R handheld at the main drawing.

Pictures are here:


Man that Eye-Fi SD card for my camera is great. :-)

DCC Day Two - SDR Cube

George Heron N2APB and Juha Niinikoski, OH2NLT - SDR Cube: A portable SOftware Defined Radio Utilizing An Embedded DSP Engine for Quadrature Sampling Transceivers

George and Juha have designed a complete SDR transceiver in a 4" x 4" cube.  It contains a Softrock RxTx v6.3 and an embedded DSP controller a graphic LCD display and all controls.

It also allows connecting the NUE-PSK Digital Modem for various digital data modes.

They expect to cell kits and assembled versions sometime in the next couple of months.
