Lost Friends
This week has not been a good week, very sad, two of my Ham Radio Friends have passed away.
Doug Phillips - W7RDP (SK) a good friend from the local Pacific QRP Group (pQRP).
Don Sehulster - K7QYP / W7LSC (SK) - a very good Navy Buddy (1968-1972).
73 - My Friends . . . K

A 30m Signal Black Hole
Last night, Oct 8, 2009 about 8pm (local) I checked my WSPR receiver for activity - there was NONE!
It was like the receiver was disconnected from the antenna - in fact, I checked all of the antenna connections looking for a problem. The S meter was indicating near zero for background noise. Only the "heart beat" of my electric fence charger moved the needle off of zero, I unpluged the charger and then, . . . Nothing, Nada, Zip - S Zero!
At intervals, only one station, a friend, Doug W7RDP (about 21 miles away) was being Heard and Reported via WSPR. Which was also unusual in itself, as we do not often report each others WSPR signals. Doug was also not being Heard or Reporting any other WSPR stations.
Also, there were no QRSS signals being heard. My QRSS Grabber was blank - it looked like an off-station TV screen.
I must have been in "A 30m Signal Black Hole"!
This was very unusual, normally about 8pm, 30m is HOT.
The only thing that I suspect, for the lack of signals in-or-out of my QRH, was the strange weather. It had been a clear all day, followed by a very dense low overcast evening.
Could contrasting weather layers trap signals in, and prevent outside signals from reaching my antenna?
I wonder if anyone has ever report this type of signal or weather related condition?
It would be interesting to review the WSPR data base for when the "Black Hole" effect started, how long it lasted, and how large an area was affected.

pQRP P&C Meeting
The following was reported by Wayne, after our Puget Sound QRP (pQRP) Pie and Coffee (P&C) Meeting, republished here as an archive.
Note: I did not invent the Toner Transfer Process to produce PCB's, I used a lot of information form the WEB, thanks to the many people that have gone before me.
Hello All,
We had a great turnout at P&C last evening, with fourteen of us around the table. Here's the list:
Roger, K7RXV
Jeff, KO7M
Rod, WE7X
Eldon, WA0UWH
Charlie, K7KN
Bob, W8MCJ
Rick, K7MW
Lyle, KK7P
Doug, W7RDP
Rich, AC7MA
Brendan, N0BML
Bill, WA7NCL
John, KC7NVE
Although most of us have been busy with summertime activities, there have been a few projects going on.
Eldon, WA0UWH, has worked out a method for producing PC boards, using an ink transfer method involving a laminating machine. He'll have to explain it in detail for us, but it looks very interesting.
He brought his 40 dB Tap project along for show and tell, also, having cut the PCB material to Roger's specifications and now getting ready to build it.
Eldon is making his shop available to any of us on the 3rd Saturday of each month, for radio or other types of building projects. He has everything from wood working equipment through metal working gear, including a lathe and milling machine.
Lyle has built his RF Test Set, and his lack of output from the DDS board was caused by the fact that his DDS60 is an older one with a different DDS chip and clock frequency. Rich is going to try to adjust the firmware so that Lyle will be able to use the older daughterboard.
I have been so busy with being the Commodore of my local yacht club, hosting company, and the usual summertime activities, that I have not been doing any building projects and have not been on the air, either. My time will free up a lot in late October, and the onset of the rainy and dark season will turn my interests back to the workbench and paddles.
Jeff, KO7M, brought his recently built HF Packer Amp, that he built from a kit, and it is very nicely packaged and will be a nice addition which will give his QRP RF output a good boost to help make contacts in this time of low sunspot activity.
Bob, W8MCJ, came with a box of free stuff like coax cables, some ham related books, and gave a copper ground strip with braided connecting wires to tie rigs together and to ground as a door prize. Lyle gratefully received this unit.
As usual, the discussion around the table was varied and lively, ranging from a little teasing towards Doug, W7RDP, about the recent docking mishap with the Wenatchee, the Washington State Ferry he works on, to various computer programs for MAC and Windows Vista, as well as QRP Radios and operating events.
Bill, WA7NCL, talked a bit about operating in a recent "Bumblebee" event, and made a suggestion for next Salmoncon, saying that since we tend to focus on building projects, we should have an operating event at Bowman Bay, where we each put together a portable QRP station, hike over to the point, throw an antenna over a tree, and operate for a while. Could be a lot of fun.
Rod, WE7X, brought in an award that he and Doug, W7RDP, had won in a recent VHF Contest. Roger, K7RXV, had been along on that trip as well, but didn't operate.
Brendan, N0BML, talked about his building project at Eldon's last shop gathering, which was a homebrew charger unit for his cell phone. Brendan is also practicing CW and getting ready for an upgrade to his license.
If I missed anything, it was simply because there was so much being discussed.
In short, it was another very enjoyable evening.
