WSPR 40m (7.0 - 7.3 MHz) band activity data recorded for 3 x 24 hour periods on 14 and 15/07/2017 and 17/07/2017

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): 24

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

Antenna:  Antenna#1 Sloper Antenna  -  40 & 15m Bands with T-Match tuner  

               Antenna#2 Multi-band dipole with T-Match tuner and 4-1 Current Balun 

This exercise was to compare the 40/15m band sloper antenna with the main station antenna used for operations on the 40m amateur band.

WSPR 40m band activity data recorded for 3 x 24 hour period on the 14, 15 and 17/03/2017 showing SNR against UTC time, Vertical axis = dB below the noise floor.
