WSPR - 40m BAND - 17/10/2017 ~ 20/10/2017

WSPR 40m (7.0 - 7.3 MHz) band activity data recorded for 3 x 24 hour periods from 17/10/2017~20/10/2017

HOME  > OPERATIONAL >WSPR >

 

Data from the WSPR web site relating to monitoring and transmission from VK6YSF Northam Western Australia.

WSPR Frequency: Dial 7.0386 MHz USB (occupied bandwidth 7.0400 - 7.0402 MHz)

Grid location: OF88II

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

Receive and transmit

SSN (Sun Spot Number): 34

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 40m amateur band.

 

Conclusion is that there is no compelling performance deference between the Doublet Antenna and the L Antenna.

 

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

VK6YSF JS8Call and Olivia 8/250 operations.

Current activity is generally focused - though not restricted to - JS8Call operations on the 30m, and 40m bands.

Olivia 8/250 is used occasionally on the 20m band.

Proposed band and mode activity is often communicated on HamSpots: https://hamspots.net/js8/ or my profile on
