October Meeting VENUE CHANGE!

posted Oct 15, 2014, 4:22 PM by Brian Lawler   [ updated Oct 15, 2014, 4:25 PM ]

Just a reminder, the meeting this month is NOT going to be at the Ferndale library! Instead we are going to be at the Foundry in Bellingham!

The foundry is at 1515 N Forest Street. Here is the google map link and if I did it right you just need to enter in your address and it'll give you directions to the foundry:

For those coming from outside Bellingham:

Take the Lakeway exit
turn right onto lakeway so you are headed into town
keep going on holly street (get in the right lane)
turn right at forest street, get in the left lane (though if there is no parking you'll have to go around the block and get into the right lane and try again)
Find a place to park.

If possible try to share a ride, I'm going to try to keep some of the other spots closer to the door open for those who have issues walking.

If you have any questions feel free to email me. (

CHIRP Primer

My apologies for forgetting to post the CHIRP Primer that I wrote as an adjunct to the presentation I did at the October meeting.  You will now find it in the FILES section under the Digital Group menu.  There are links in the document for local area amateur and public safety frequencies.

At our last Digital Group Meeting a couple of the guys were asking if I could share the document  by John A. Hansen, W2FS. He is the creator of the TNC-Pi. This document includes some notes that are not available on the TNC-Pi web site that might be helpful to anyone building the kit.
I found a link to a digital copy of that document.  Maybe you could post it so those who want it can download it themselves.

April 2013 Meeting Notes

posted Apr 16, 2013, 10:50 PM by Brian Lawler

The April meeting was a help-fest to get people up and running with FLdigi software.  Before the playtime began we discussed whether we should purchase one or more UDR units from  Chuck Keiper moved and Budd Churchward seconded a motion to register the club's INTENT to purchase two radios.  The motion passed with NO dissenting votes.  This was not a vote to make the purchase  since the company is not actually taking $$ yet.  In addition, four individuals registered their intent to purchase single units for their themselves so KN0N collected that info and registered the information on the NWdigitalRadio web site.  By the way the treasurer KC7IJH read the bank balance (which I forgot to write down) but it was North of $1700 and we have 18 paid members for 2013.

November DG Meeting:

Our special guest was Bryan Hoyer who showed  a prototype of the UDR56K-4 "smart radio".  The unit is a transceiver/computer hybrid that can perform just about any digital communication task that you ask it to.  Details are at the NWDigitalRadio web site.

December DG Meeting;

Art Miller has launched his project to provide refurbished PCs to a non-profit organization. For details contact him at

KN0N showed his "Pirate Box" a pocket sized cordless/wireless chat/bulletin/file server.  PirateBox uses a cheap TP-Link wifi router ($23),  USB thumbdrive ($6), and battery ($10) with a modified version of Open-WRT firmware.

KN0N also showed how to use the Signalink USB as a packet TNC to connect to RMS servers via VHF.  The TNC function is performed by the Signalink and UZ7HO SoundModem software.  The Winlink client is Packlink, available from   The final piece required is an email client for sending and receiving through Packlink.  Your favorite will work as long as it supports POP3 and SMTP.  "Popcorn" is my current lightweight choice.  As far as I know, the Soundmodem is only supported on Windows machines.
