WSPR - 12m BAND - 12 ~ 16/11/2017
WSPR 12m (24.890 - 24.990 MHz) band activity data recorded for a 4 x 24 hour periods on the 12 ~ 16/11/2017
Data from the WSPR web site relating to monitoring and transmission from VK6YSF Northam Western Australia.

WSPR Frequency: Dial 24.9246 MHz USB (occupied bandwidth 24.9260 - 24.9262 MHz)

Grid location: OF88II

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

Transmission Power 33 dBm (2Watts)

SSN (Sun Spot Number): ?

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

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

                40m Sloper Antenna:  Sloper Antenna  -  40 & 15m Bands with T-Match tuner    

                10m Sloper Antenna:  10m Sloper with T-Match tuner  

                 L Antenna:                L Antenna with T-Match tuner  

 

 

This exercise was to compare the Multi-band Doublet Antenna, 40m Sloper Antenna, 10m Sloper Antenna and the L antenna for operations on the 12m amateur band.

 

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

 

 

 

WSPR 12m band activity data recorded for 4 x 24 hour period on the 12-16/09/2017 showing SNR against UTC time, Vertical axis = dB below the noise floor. 

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