WEAK SIGNAL DX USING THE TECSUN PL680




WEAK SIGNAL DX USING THE TECSUN PL680
Mini DXpedition - September 30, 2016


 Here is a demonstration of the sensitivity of the Tecsun PL680 portable receiver on a visit to Mount Prospect, near Daylesford, Central Victoria during a time of high geomagnetic storm activity. The 680 proves to be remarkably sensitive in detecting weak signals. Click on the YouTube video below for more details.....but watch out for the WILD ANIMALS!!

    Great DXing. I intend to do this too, specially now that summertime is approaching. The weak signal you got on 11780KHz could be from Radio Nacional da Amazonia from Brasilia-DF, Brasil. Most of the frequencies on your video I also tune here in southern Brasil. I wanted to purchase a PL-680, but first I'll give my PL-660 another chance. by trying and making a bypass that will stop that annoying squelch-like filter. I'll follow instructions from a Brazilian ham colleague who in turned learned from an Italian ham operator. Thanks for posting! 73

      Thank you Julio. There's probably not much difference between the 680 and the 660. Other people say that the 680 is a little more sensitive than the 660. But they say that the 660 is better on mediumwave. Any way, good luck with your 660 and good dxing for the coming summer months! Rob.

RETRO RECEIVER REVIEW # 21 - The Kenwood R-5000

RETRO RECEIVER REVIEW #21 (You can click on all photos in this article for a close-up view) KENWOOD R-5000 Performance and Innovation by ROB WAGNER VK3BVW This extended blog post first appeared as a feature article in the February 2024 issue of The Spectrum Monitor magazine. Further details on this excellent publication are available at www.thespectrummonitor.com I have always wanted to own a Kenwood R-5000 receiver. Perhaps I was dazzled by the mystique that appeared to surround this rig. Somehow, it had always been on top of my bucket list of pre-loved rigs that I wanted sitting on the desk of the radio shack.  Finally, one showed up at a local Sunday morning Hamfest, and I happened to have just enough dollars in my pocket to make a purchase. It appeared to have lived a hard life. The case looked knocked around and was pretty dirty inside and out. So, while I would have liked to have owned a unit in better condition, the price was right, and I decided to take it on as a l...

PRODUCT REVIEW: WELLBROOK ALA1530S+ LOOP ANTENNA by Michael Stevenson (Guest Contributor) This is a review and my opinion of the Wellbrook ALA1530S+ P–1 Active receiving Antenna. For further information, details and specifications then please visit: www.wellbrook.uk.com Background I have been a keen shortwave listener since 1970 and have had many receivers and antenna types during this time. Currently I have two wire antennas, a PAR Electronics EF-SWL 15 meter with impedance matching transformer, made in the US; and a home made 17 meter wire with balun. I also have a dedicated multi-stake ground or earthing system to compliment my receiver and antennas. I live in suburbia Port Macquarie, New South Wales on the east coast of Australia. Even though all our electricity wiring is under ground in our housing estate, I live in an environment where there are all types of man-made noises coming from modern electronic and electrical equipment used by my neighbours The wire a...

RETRO RECEIVER REVIEW #20 - The SONY ICF-5900W

RETRO RECEIVER REVIEW #20 SONY ICF-5900W by CRAIG SEAGER VK2HBT This time around, I thought we might direct our attention to one of the many portable receivers of yesteryear, and it is perhaps appropriate that we choose a manufacturer that continued to produce quality equipment featuring shortwave coverage until long after. I’m sure our Japanese friends will concur with the submission that Japan is a land of short-lived, but enthusiastically embraced fads.  Whether it be karaoke, yo-yos with brains, electronics pets or Pokémon, each craze sweeps the country in such a way that captures the attention of the rest of the world and is usually associated with some pretty smart home-grown technology.   In the mid to late 1970s, shortwave listening (or “BCL”) was the flavour of the month, with teenagers (and some older folk!) compiling large QSL collections and forming SWL and DX clubs all over the country.  Nowadays, you’d be fairly hard-pressed to find any external broadcas...
