Listening to HF Nets With Inverted V Zig-Zag Antenna!

Listening to HF Nets With Inverted V Zig-Zag Antenna!

Couple of days back I had posted on Checking RX on FT-710 AESS with RG 213 and No Antenna and yesterday I had posted on Trying to Build a 40 Meter Inverted V Dipole in Zig-Zag Fashion. Antenna has been hosted, but I could not finish tuning the antenna yesterday. Today morning I thought of checking the reception on the untuned antenna. After attaching the antenna, tuned to 7050 kHz in the radio, the Belgaum Net frequency and found that the reception had improved very much as you have heard in the beginning and so had the noise level, which was 5,9 as well!

Yesterday there was hardly anything to be seen on the 3-Dimension Spectrum Stream (3DSS) colour display. Now the whole display is full, mostly due to the high noise level. The frequency span is shown on the horizontal X axis of the 3DSS while Y axis depicts the signals and their strengths. The receding Z axis represents time. Though the 3DSS is nice to see, it also implies the high noise level in my region. Still, net controller and many of the stations heard were overriding the noise level.

What you heard just now was the Charminar Net on 7080 kHz. There the net controller was heard even louder, being nearer to my location. On 40 m, during daylight time I have noticed that local stations come up better than more distant stations. At night, distant stations may be better because the skip distance increases. During day time, very nearby stations beyond the region of ground wave propagation may be in skip. Those stations are within the skip distance for that band. HF propagation is a dynamic process, with a lot of variation according the level of ionization in the various layers of the ionosphere. In contrast, VHF and UHF propagation are mostly line of sight and less dependent on such factors, though line of sight propagation usually limits the distance of communication very much.
