WSPR Frequency: Dial 28.1246 MHz USB (occupied bandwidth 28.1260 - 28.1262 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  

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

Conclusion is that the 40m Sloper Antenna, and the 10m Sloper Antenna have the best performance.
