> Next Online Club Meeting: January 17
Our January NJQRP club meeting will again be an online meeting. It is set for Tuesday January 17 at 8 pm Eastern. We also plan to have an in-person meeting each quarter (to see projects in-person, demos, etc.), and have the in-between months be for online meetings.

> See Notes & photos of our Group Build
We had a great group build "Workshop" last Dec 11th at the Armstrong Hall Engineering Lab at the College of New Jersey. Great thanks to Professor Al Katz (the famous UHF ham) who let us use the engineering lab to continue the build-up of our Ensemble RX-II kits. A big thanks to Joe Jesson, KC2VGL for arranging this venue, which could become a regular place for the continued stream of Group Build activities that we have planned for the club. The Ensemble RX II is an all-HF band receiver kit that includes the components for building the receiver for HF operation (1.8 MHz through 30 MHz). We're looking forward to getting this compact little receiver working first with the PC, and then shortly thereafter with a small project board (our follow-on group build) to eliminate the need for the PC. "We don't need no stinkin' PC!"
> The SDR Cube Transceiver is available
Think you need a PC to use that "quadrature sampling" Softrock? Think again! Here's a new, compact, killer all-mode transceiver that's perfect for taking to the field ... All the thrill, flexibility and performance of Software Defined Radio, without the hassle of lugging along that darned PC.
> Midnight Design Solutions NUE-PSK Digital Modem
If you think portable PSK31 operation requires a laptop computer, Midnight Design Solutions has a surprise for you! Their NUE-PSK Digital Modem is available now.
> NJQRP Resource Page
We have collected some great sources of information and posted them in a web page called "NJQRP Resources", check it out at http://www.njqrp.org/resources/index.php.
> NJQRP Yahoo! Group
After 10 years of faithful service (thanks to Bob, K2UT) we have retired our old email list server and moved to a Yahoo! Group. This group continues to let us share email with everyone as well as adding many new features. The old mail list server was retired at the end of 2007. Click the image on the left or see this page for instructions on signing up for our Yahoo! group.
> HC908 based VFO
For those of you looking to build station/lab accessories , George posted info about a the Micro908 kit which is a re-usable control and computing platform which can be use for antenna measurement, digital modems, audio filtering, signal source, VFO, memory keyer and more. Take a look at it over on the Midnight Design Solutions site..
> Club Counter Kit
If you were lucky enough to pick up one of the NJQRP Counter Kits at one of our recent meetings (sorry no more kits are available), all of the construction info is available here.
> Rookey kits still available
The Rookey (Remote On-Off-Keyer) kit from Atlanticon 2007 is still available. The kit consists of an audio decoder PC board, all on-board components, small FM receiver, audio patch cord, ear buds, 9V battery clip and an extra blank PC board. The PICAXE microcontroller IC supplied with the decoder board is preprogrammed with a BASIC software program that decodes incoming audio pulses to illuminate any one of four LEDs and activate your own custom remote control circuits (e.g. a driver for a remote antenna switch).
Additional software is available for the Rookey boards, provided by PICAXE enthusiast David Gwillim, KB2TQX. Dave's programs allow the Rookey board to function as a Randon Morse Generator, Iambic Keyer, Koch Method Morse Trainer (KMMT) and a temperature controller. This source code is also freely available here, and we have a limited number of KMMT kits with the PC board and components needed to make up the KB2TQX circuits.

> Micro908 Kit
The Micro908 is a multi-function, handheld computing platform that has a growing number of real useful purposes around the shack: Antenna Analyzer, DSP-based Audio Filter, and (soon) PSK31 modem and a Software Defined Radio receiver. All details and options can be found on the project web page at http://www.amqrp.org/kits/micro908.
> Elmer 160 Course - learn how to program PICs!
John McDonough, WB8RCR has designed an on line introductory course for learning how to program and use PIC micro controllers. As course instructor, he will start off with very basic principles, and take students to the point of designing their own PIC applications. While the focus will be on the PIC16F84 chip, principles are applicable to the entire range of micro controllers from Microchip.
