Shortwave listening and everything radio including reviews, broadcasting, ham radio, field operation, DXing, maker kits, travel, emergency gear, events, and more
I tuned the 7,390 kHz frequency of Radio New Zealand at 14:10 UTC on November 16 on the 4 receivers. I used the narrow and wide filter on each receiver.
I state that a storm was in progress in the area, the afternoon signal was very discontinuous with a difference on the 3 different antennas.
Surprising the result of the internal cross loops which I use a lot when there are thunderstorms in the area to listen to anyway; their behavior is definitely very good despite being inside my shack.
The Mini Whip is excellent on long and medium waves but gets worse above 7 MHz. In fact I only use this antenna for medium and long waves.
A good signal also from the external naval vertical of 8 meters with a “soft” listening on the Yaesu FRG-8800.
Judge dear friends your comments are welcome!
I wanted to compare these 4 “glories” that have accompanied most of my life and that I still consider excellent.

I wish everyone a good listening …

Thank you so much for sharing this, Giuseppe! We love your videos and demonstrations especially since they so often involve antennas that you have home brewed. Your cross loop antenna is truly amazing!

QSL— Direct to VU2DSI, “SURABHI” MEHERABAD. AHMEDNAGAR.414006. INDIA.
FOR DX STATIONS PLEASE SEND 2IRC’s—–IF POSSIBLE— as many many DX stations are requesting QSL’s.
I will appreciate the GOOD number of used postal stamps instead of IRC as I love collecting stamps.
About
Aacharya J.C.Bose is well known as the “Father of Wireless Communication”.
Acharya Bose’s demonstration in 1895 & 1897 predates all.
Bose transmitted wireless signals to a distance of a mile. Popova in Russia was still trying remote signaling at this time & the first wireless experiment by Marconi was not successful until May 1897.
Bose is a pioneer in microwave optics technology.
Bose’s invention of 1-centimeter to 5 millimeters radio waves is being used in radars, satellite communication& remote sensing.
Bose’s concepts from his original 1897 papers are now incorporated into a new 1.3 mm multi-beam receiver on the NRAO (National Radio Observatory) 12 Meter Telescope.
Bose anticipated the use of P-type& N-type semiconductors & hence 60 years ahead of his time. Bose developed the use of GALENA crystals for making receivers.
In Bose’s presentation to the Royal Institution in London in January 1897, he speculated on the existence of electromagnetic radiation from the sun. This radiation from the sun was not detected until 1942.
My Dad and I took a road trip to tour the 1 MW FM community tower in Crestwood, MO, serving the entire St. Louis metro area combining 10 FM radio signals into two antenna systems.
Special thanks to the Audacy engineers who allowed us to take a peek at their (very clean!) transmitter rooms and equipment!

Many thanks to SWLing Post contributor, Frank, in Germany, who shares the following guest post and review of the Deshibo RD1860BT:
Deshibo RD1860BT report
Hello Thomas,
Today I would like to report on a new portable world receiver. Unfortunately, new devices have not been found on the shelves of electronics retailers for a long time, but now in the depths of the world wide web. And that’s how I came across the Deshibo RD1860BT.
Deshibo is certainly known to many from their GA450 loop antenna. But Deshibo has also produced several radios, including the RD1780L, which is probably a little better known. New to the segment is the RD1860BT, which initially seemed like an old friend to me. An Eton Elite Executive? Yes, there are external similarities, but also differences.
Many months ago I had an Eton Elite Executive for a short time. I had heard of its excellent reception properties, which I can confirm, but the design is reminiscent of older receivers from the 80s, is relatively heavy, operation is sometimes a bit cumbersome, the protective cover does not protect properly. I find the device to be portable overall difficult. We didn’t become friends, so I sold it on to a Swede, who in turn became a friend.
I still missed the Eton. RDS on VHF is not found in any Tecsun , nor are there memory banks that can be written on.
Then I discovered the RD1860BT and couldn’t resist. First of all: the Deshibo is only labeled in Chinese for important function keys. But the friendly dealer on eBay provided me with an English manual before I bought it. That was the deciding factor, because I was sure that after a little use , the Deshibo could be operated blindly.
However, some questions have arisen in the user manual. Some things didn’t seem quite right, others were completely missing from the description. That’s why I decided to write my own manual on a journey of discovery of the new Deshibo. And so that it might also help others who might be interested in radio, I wrote it in English and attach it here.
The Eton’s somewhat unsorted manual was very helpful, but I also added my own drawings. For example, I added an English-labeled keyboard as a back cover, so that the keys can be assigned without a long search.
Here you can already find the first differences to the Eton: the keyboard layout is a bit more orderly. Also, the Deshibo doesn’t have a metallic speaker grille (which frankly I don’t like about the Eton). The display, not the writing, is backlit in orange on the Deshibo . Most importantly, the Deshibo is a lot lighter than the Eton ( around 500g if I researched correctly). And that means: the structure of the Deshibo must be different. Continue reading →
