Club Experiment on Sunday, September 28th

We plan on conducting a "club experiment" on Sunday September 28th, starting at 6 PM.  Purpose of the experiment is to compare "ground wave" propagation between 40m and 30m, as well as conventional propagation on 2m (both SSB and FM).  Our intent is to see which digital modes can be worked consistently at which distances.  Three club members are currently in the planning stages for a combination radio/modem package that will be small and easy to deploy.  We will use the results of Sunday's experiment to decide upon which frequencies and modes to use for the final design.


If you have equipment, you are welcome to participate.  Here are the details:

6 PM         (7036 khz, 1500 hz center frequency)

6:30 PM   (10140 khz, 1500 hz center frequency)

7 PM        (145.01 Mhz, FM, 1500 hz center frequency)

7:30 PM   (144.16 Mhz, USB, 1500 hz center frequency)

Required equipment: Multi-band HF transceiver, VHF multi-mode transceiver, Soundcard interface, FLDIGI software.

 

All operations will be at 5 watts or less to establish a low power basis for contacts.  No long transmissions (bulletins or messages) this time around.  Primarily will be quick transmissions to establish if station is being heard and if text is readable.  Will start out on PSK 125, then go to PSK 500, then finish at PSK 1000.  Once again, will compare stations being heard and readability of text.
