WSPR - 20m BAND - 31/10/2017
WSPR 20m (14.00 - 14.35 MHz) band activity data recorded from 29/10/2017 to 31/10/2017
Data from the WSPR web site relating to monitoring and transmission from VK6YSF Northam Western Australia.

WSPR Frequency: Dial 14.0956 MHz USB (occupied bandwidth 14.0970 - 14.0972 MHz)

Grid location: OF88II

Local Time = +8:00 hours (0:00 = 8:00AM)

Transmission Power 37 dBm (5Watts)

SSN (Sun Spot Number): 33

Equipment: TS-930 at 5W, Radio computer interface

Antenna:  Doublet Antenna: Multi-band dipole with T-Match tuner and 4-1 Current Balun   

                L Antenna:          L Antenna with T-Match tuner  

 

This exercise was to compare the L antenna with the main station antenna used for operations on the 20m amateur band.

 

Conclusion is that there is no compelling performance deference between the Antennas.

 

WSPR 20m band activity data recorded from 29/10/2017 to 31/10/2017 showing SNR against UTC time, Vertical axis = dB below the noise floor. 

 

WSPR 20m band activity data recorded from 29/10/2017 to 31/10/2017 showing distance in km against UTC time.

Vertical axis = km

 

WSPR data has been graphed using Excel. Horizontal axis = UTC Time, Vertical axis = dB below the noise floor.
