SWL and QSL cards a love story

 Many listeners like to send a reception report and to receive a QSL card. Now in 2023 you can send you reception report with a mail and receive the QSL also by a mail via intenet. We call this a E-QSL.




reception report is a means by which radio stations (usually short- and medium-wave broadcasters) receive detailed feedback from their listeners about the quality and content of their broadcasts. A reception report consists of several pieces of information which help the station verify that the report confirms coverage of their transmission, and usually include the following information:

  • Date, time and frequency (in kHz) of the transmission
  • Station name
  • Description of the interval signal, if heard
  • Programme details
  • Name of announcers or programme host, if heard
  • Details of the overall signal quality (normally using the SINPO code)

The listener's location relative to the station is also useful; this indicates how well the station's transmitter is performing and in which direction(s) its antenna is beaming the signal. The station also evaluates a reception report in light of the listener's receiver and antenna. Upon receipt of a correct report, a broadcaster sometimes issues a letter or postcard (known as a QSL card) to the sender, thanking them and confirming that the details are correct. "QSL" is part of the amateur radio Q code, meaning "I acknowledge receipt". One aspect of DXing is collecting QSL cards and letters from stations heard (similar to a birdwatcher's "life list"). QSLing a radio station involves writing an accurate reception report, mailing it to the station and awaiting a reply. Since QSLing is a voluntary act on the station's part, several techniques are used to improve a listener's success rate.

In the past it was only possible to send a reception report by a letter and the post office. So you must pay for stamps and some radio ask contribution.

Some listeners use " green stamps " who was a green bank note of 1 US $ !!!

But sometime now answer like for me when i try to comfirm Tunisia 30 years ago. They like my green stamp but they dont send a QSL card !!! Because of these radios who dont send QSL card i decide to listen to amateur radios bands...

Some paper QSL card we realy beautifull like this one from Portugal.

In the past they are many radios on SW, MW and long wave. 

In 50 years we loose 1040 radios on tropical bands 2300 kHz to 5800 KHz


Not only SWL of AM radio love QSL cards. The pirate radios, clandestines radios, utility stations, CB radio operators, Amateur radios echange QSL cards. For amateur radio they are 340 DXCC entities. When i listen to hams 30 years ago i send and receives QSL cards from 250 DXCC. 


It was my paper QSL card to send to amateur radio operators by post office.

Now i make e-QSL for hamsphere 5 who is a program of virtual ham radio via VoIP and internet.



They are a lot of web page and blogs with collection of QSL cards. 

I think the best for listeners of AM radio on SW and Mw is this one

Up to 50,000 broadcast QSL cards from voices from all over the world, confirmation of receipt for the passionate wave hunters: international, regional and local stations, the electronic church, underground stations and pirates, from the pioneer days to today.

Ten-Tec Founder Jack Edward Burchfield K4JU Silent Key

 Jack Burchfield K4JU, 88, last surviving founder of Ten Tec, passed away on 15 July 2023



Jack began his career at Electro-Voice in Buchanan as an acoustic engineer. In the late 1960s, with Albert Kahn and Tom Mitchell, he founded Ten-Tec, a manufacturer of amateur radio equipment in Sevierville, Tennessee. Jack designed the initial product line and most of the radio equipment that followed. His radios were on display at the Smithsonian Museum of American History for many years. He was an amateur radio enthusiast and was inducted into the Amateur Radio Hall of Fame in 2004.

The TEN-TEC name was coined from Tennessee Technology. The company was founded in 1968 with the goal of designing and manufacturing amateur radio equipment. The first products were simple, low cost QRP (low power) transceivers. The more advancedArgonautQRP series was introduced in the early 1970's, staying in the product line with successive models until the early 1980's. TEN-TEC pioneered solid state, no-tune 100 watt H.F. transceivers with the Triton II and IV in the mid 1970's. These early designs spawned development of 16 different H.F. amateur rigs over the next twenty years. TEN-TEC has produced linear amps for over 15 years. Most receiver hobbyists knowTEN-TEC through their model RX-10 or RX-325 models. However, their most successful receiver is the RX-330A commercial, DSP model enjoying wide use in commercial and government markets. TENTEC currently offers two affordable "regen" shortwave radio kits. Expanding several times, TEN-TEC currently has a 40,000 square foot plant with 100 employees. They are active in three businesses today. The largest division is the combined amateur, commercial and government electronics division. TEN-TEC has a tool and die division making molds for the die casting and plastic injection field. The third division makes standard and custom sheet metal for other manufacturers.
