MINUTES of the March 2nd Meeting 
The 50 MHz and Up Group met at the Lockheed-Martin auditorium, Bldg. 212, on Page Mill Rd., Palo Alto, on March 2, 1997. There were 24 people in attendance, and the meeting was called to order at 1:15 PM. Club officers that were present were: Jeffrey WA6KBL, President; Bill AA6PA, Vice President; Will W0EOM, Treasurer; Bill KQ6FY, Secretary; and Jim WB9AJZ; and Art W6RXQ, directors. 

The speaker for May's meeting was announced: Lance Ginner will discuss the communication systems on Mt. Umunum. 
During the Pacificon Conference, in October, the club has reserved time for presentations starting at 1:00 PM on the Saturday of the conference. Antenna testing will be held in the back parking lot in the morning. A call went out for any interested club members to prepare presentations for this event. 

An application was made for ARRL affiliation, and some progress was reported at getting the club incorporated as a non-profit entity. A request was made for someone to make phone inquires to get the necessary non-profit tax forms. 
The treasurer reported that the club had a bank balance of $1307. An contest was announced, related to the upcoming Foothill Flea Market. The first club members to get there before Lars would be winners. No prize was announced. 
There was a brief discussion on the use of GPS as a frequency standard. Tom Clark, the founder of AMSAT, who works at the Goddard Space Flight Center, in Maryland has designed a board that uses the 1 pps signal from GPS receivers to phase lock reference oscillators. This board will be sold by TAPR. Art Lange confirmed that the GPS units sold to club members have the necessary features. 

A requirement was expressed for software to help put the club newsletter on the Web. There was opposition to the expenditure of club funds to buy software for this purpose, so alternatives were discussed. The need was for someone to take Jeffrey's Frame Maker output file and convert it into an HTML file for display on the Web. Kevin Hague N5XSA volunteered to do this. The question was asked whether we should put our newsletter on the Web, so a vote was taken. It was approved 8 - 5 to continue this. 

In other business, it was announced that the club roster has grown to 46. The latest copy of the Western States Weak Signal Society newsletter was circulated. A new award from the NorCal Sidewinders On Two was announced: The worked all California counties. 

Ken Kitlas KD6OBU, gave a very interesting talk and slide show on his exploits in the field of Amateur Rocketry.

Note from John: 

There is some 50 MHz and up activity here. I operated in the January contest with temporary antennas. I have made a new friend in W7GBI, Charlie, who is very active on EME (432, 1296, 2304). I have worked him several time on 1296 and 2304 (terrestrial). I have also talked with Jim Vogler, WA7CJO, of 10 GHz fame! Charlie and I are trying to get more interest going on the microwave bands.

Spread Spectrum Docket 97-12 

Text format see: 

http://www.fcc.gov/Bureaus/Wireless/Notices/1997/fcc97010.txt 

This NPRM was submitted in December by ARRL to allow an increase in the allowable types of spread spectrum emissions allowed by amateurs. It restricts power to be automatically controlled if more than 1 watt is used. In no event is more than 100 watts allowed. It allows SS to be used only in bands above 225 (same as current). 

Comments are due by May 5, 1997, and reply comments by June 5, 1997. For formal comments, you must file an original plus four copies of all comments and reply comments. If you want each Commissioner, to receive a personal copy of your comments, you must file an original plus nine copies. Address them to: 

Office of the Secretary of the Federal Communications Commission, Washington, DC. 20554.

A Call for Amateur Payloads   
The ERAST program, run by NASA is involved in flying remotely piloted airplanes (RPA) with environmental sensing payloads. One of the goals of this program has been to involve as many other groups as possible - hence the ERAST Alliance. This summer, several long duration flights are planned; with some at high altitude. The Program Managers have expressed an interest in flying an Amateur Radio payload, to be built and operated (remotely) by Hams. This would fall under the same category as the SAREX operations on the Shuttle, and would be dependent on getting an FCC waiver and support from interested Hams. The kind of payload envisioned is a cross-band repeater, with periodic CW ID and broadcasts of navigational telemetry via a packet protocol. Once the RPA is airborne, the payload would be switched on and could be used as a mobile repeater by Hams along its flight path. All contacts through the RPA repeater would be logged by each Ham, with the time, signal report, station worked, and any telemetry received. These logs, along with details about the stationís location, antenna, power, etc. would be sent to ERAST, to be used for link analysis. An award certificate would be issued to all participants who provided data. The purpose of this experiment is to evaluate the usefulness of an airborne repeater for emergency purposes. This would likely be a one time experiment and any operational repeater based on this experiment would not use Amateur frequencies. The first level of support for this proposal that ERAST would like to solicit is from amateurs who would like to build the payload. The payload would remain the property of the builder(s), and would be developed with no remuneration. A payload that is light weight, can operate in band despite temperature extremes, and is designed as a compact, self contained package would be desirable.
