Tecsun pl 330 shortwave radio

The Tecsun PL-330 is the latest pocket-sized portable receiver offering SSB capability. This feature, coupled with direct frequency entry makes the PL-330 the ideal receiver for those wishing to listen to shortwave radio utility stations, amateur radio transmissions as well as regular shortwave broadcasts.

Our Tecsun PL 330 has been featured in the latest edition of Australian DX NEWS For those of you considering adding a PL 330 to your collection, this review is thorough and comprehensive.

Tecsun PL330n review.

As mentioned this lightweight SSB radio is feature-packed click here to view all the features of the PL-330 and buy your own. Priced at just $145 this radio is also the perfect gift for fellow radio enthusiasts or soon-to-be hobbyists.

As the weather begins to cool, it is a great time to set up and organise your radio shack.
Crucial for wireless communication, the first radio shacks were aboard ships in the 1900s, several radio units were housed above the bridge in wooden structures.
Similar to a man cave the radio shack is essential for every shortwave listener, it is your place to get away from the hustle and bustle.

Many radio shacks are set up in basements, garages, or spare rooms.
Some important factors to consider are.

Location: Ensure your radio shack is as close to the ground as possible with accessibility for routing wires in and out of your space.
Comfort: Get yourself a large desk that can accommodate lots of radios and a comfortable chair so that the time you spend in your shack is enjoyable. Get yourself a good set of headphones that can plug right into your radio, preferably like our Tecsun communication headphones that feature an extra-long cord so it can reach even the higher up radios in your radio shack.
Ease of use. We mentioned the large desk earlier, it is important to have your units within close reach, at least within arm’s length. Buying some shelving for vertical storage is both a great use of space and helps accessibility.
The Extras, just for fun! Get yourself a big clock that shows Zulu or UTC time so you can always see what time it is overseas, plus these look pretty cool!
Get yourself a corkboard that you can pin your QSL cards, decoded images, and other notes.

For those of you who have a radio shack we would love to see your photos. Take a photo and either email it through to hello@tecsunradios.com.au or post your photo and tag us @TecsunAU and #TecsunAU.

In 1843 the phenonema known as the Solar cycle was discovered by Samuel Schwabe a German astronomer who observed transitions of the Sun from periods of high activity to low activity every 11 years, over a period of nearly 20 years.

Put in simple terms, the Sun is composed of a huge ball of electrically charged hot gas. As this gas moves, it generates a powerful magnetic field. This magnetic field transitions through an 11 year cycle (known as the Solar Cycle) during which the magnetic poles of the Sun are transposed, ie the north and south poles change places.

This cycle affects activity on the surface of the Sun, such as sunspots and solar flares. The energy released by these events charges particles in the ionosphere, affecting radio propagation. More solar flares and sunspots occur at the peak of the cycle than at the bottom of the cycle. Typical values are 80-100 sunspots at the cycle peak and 15 or so at the cycle minimum.

When a strong flare occurs, the increased x-ray and extreme ultraviolet radiation produces ionisation in the lower, D (absorption) layer of the ionosphere, disrupting HF radio broadcasts by absorbing rather than reflecting signals. 

We are currently at the end of Solar Cycle 24 (calculated as mid 2020), and from this point we can expect an increase in solar activity and changed radio propagation as the maximum useable frequency (MUF) for shortwave communications increases with an increase in solar activity.

At the peak of the Solar Cycle, the higher frequencies of the shortwave spectrum are very good. Low power stations can be heard over remarkably long distances. 

At the bottom of the cycle, the current position, those higher frequency signals will not usually support normal propagation via the ionosphere. So propagation at lower frequencies will be better whilst higher frequencies will suffer.
