Hi Everyone!

The SBMS Christmas Party will be held on Saturday, December 11th 2004 at the Lab in Wilmington, CA - same place as last year. Please mark your calendars. This will be a potluck as before and more details will follow as to suggestions for food, gift exchange, etc. Please send e-mail with any questions.

Thanks, Dave - WA6CGR - Party Host wa6cgr@ham-radio.comä

Last meeting- Welcome to new member Brian Yee, W6BY of Alamo CA. and James Morris, K1UJ of Moreno Valley CA. Welcome to visitor Charles Patton of Murrieta. TEB made his first club meeting visit since joining us. Discussion was held about having the Christmas Pot Luck again. Annual Dinner in January or February was discussed. Doug, K6JEY presented a fine talk about the various digital signal processing equipment available on the market with an eye toward using the DSP for noise reduction in IF radios rather than general usage. According to Doug the NIR-10 with version 4.02 software is good for voice operations but poor with CW and costs around $50 on ebay. The NIR-12, the latest model, is good on both voice and cw operations but costs around $200. JPS, the maker of the NIR series, is out of business after being purchased by Raytheon. The Timewave DSP-59+ is good on voice and CW if you have the latest upgrade and goes for a bit over $100. The Timewave DSP-599zx with rev 5 EPROM is a lot like the NIR -12 but better at CW, and not as good at voice, and goes for $300plus. The W4RT/FT-817 is nice and small, and draws much less current that the above. It is good on voice but not CW and costs around $150. It also mounts inside most radios. Radio Shack and MFJ units are poorer than the any of the other units. DSP processing in the newer HF rigs like the IC-746Pro is done at 15 KHz IF and is very good, but means that you have to pay $1,000 or more for a new IF radio. The best deal of the bunch for simple noise reduction was an NIR 10, and second was the W4RT. 25 present
