(meteorobs) One Step Closer

[Jay Salsburg]

Hello Jodie

 

Thank you for your reply. 

 

My initial plan is to us a 30 watt amplifier with a custom-made exciter in the Amateur band of 50 – 50.1 MHz, allocated for CW, Beacons. One thing I notice in the allocation chart is the designation “beacon subband” of 50.060 – 50.080 MHz, where I assume CW Beacons must be situated. What these charts do not show is that the “Rules” say all transmissions must announce their “Call Sign” and physical location, every 30 minutes, an inconvenient nuisance of which I assume the modulation index must not produce modulation sidebands outside this narrow band of 20,000 Hz. My first task is to renew my Technical Certificate, which I consider an inconvenient nuisance since I am previously employed by Tektronix, a retired Test and Measurement Engineer. I have the equipment and expertise to build the exciter but I will not even start that difficult project until I renew my certificate.

 

Since a Beacon is not transmitting information, it seems logical to be able to upgrade its effective power after establishing its viability. The usual use of Beacons in this band is to test Skip and Atmospherics, this Beacon is for scientific measurement of Meteors, hopefully upgrading its effective power will be allowed. Thinking ahead, it may be better to improve the Antenna, rather than add more power.

Jay, if you read the past post on this subject, most of your questions can be answered. If you do not have access to the past post please see: 
http://www.arrl.org/files/file/Regulatory/Part%2097%20-%2004-28-2011.pdf 
section §97.203 Beacon station. 
The concept you suggest for the beacon is good. But -- and there is always a BUT -- you must follow the FCC regulations.  Or someone may file an FCC complaint about your operation. 

My earlier suggestion for an experimental license was just that -- a suggestion. A beacon can be set up in the amateur band. But others -ARRL - should also be in the loop. For the the group,  do you know the frequency you plan to use for the beacon?

You are required to meet all requirements, and employ good engineering practice.  You and you alone are responsible for its deviation, stability, etc, so have the equipment on-hand (or rented) to measure and diagnose, and know how to use it.  If you're splattering all over the band, expect problems with the Fed, but if your call sign isn't in the database, expect problems anyway.

I am one step closer to the installation of my 6 Meter Forward Scatter Beacon Transmitter. It appears there is an inexpensive way to make a 30 Watt Brick Amplifier which seems a good choice for an initial experimental Beacon.  I would appreciate any and all advice concerning installation, especially the legal stuff, like FCC certifications/registration/licensing etc.
