Radio amateur SM5SVM

Hans Sundgren is a licensed radio amateur since July 1988. His call sign is SM5SVM.

About SM5SVM

License

Hans has a CEPT-1 license. That means he must be able to communicate with Morse code at a minimum speed of 12 WPM (Words Per Minute).

He is entitled to transmit on dedicated frequencies ranging from 135.7 kHz to 2450 MHz. This represents a wavelength of 2.2 km to 13 cm.

In 1988 Hans first became a listener member in SSA with the call sign SM5-7419. He received is "C license" #71272 the 5:th of July the same year. This license was later converted to a CEPT-1 license.

Equipment

Hans main transceiver is a Yeasu FT-817 from 2001. This transceiver was occasionally connected to a 9 meter fishing pole antenna on his balcony via a home built miniature Z-match antenna tuner. Otherwise the transceiver is packed in a small case together with an MP-1 antenna and other accessories, ready to go.

Radio associations

Hans is a member, or has been a member, of some radio societies and clubs:

SM5SVM's QSL card

In 2003 Hans designs his QSL card and he prints 1000 pcs year 2005. Before that he used a neutral, single-side card, bought from SSA(?).

Log book

Paper log book

Hans first contacts are made on a hand held 145 MHz transceiver, and always via a repeater. The log book covers 6 contacts in 1989.

Electronic log book

When Hans buys a shortwave transceiver in 2001, he starts logging his contacts on the computer or hand held device.

Hans' Morse code training

Hans has learned the Morse code during 3 times:

Morse code as a radio amateur

He learned the Morse code during Autumn 1988 and Spring 1988 at Västerås Radioklubb. There were evening lessons on Mondays and Wednesdays and he passed the exam without problem.

Morse code as a private pilot

As a private pilot Hans had to learn to interpret audio Morse code, but not to transmit. The air traffic navigation beacons identify themselves by Morse code transmitted on radio frequencies.

For example, Hässlö airport in Västerås has 3 beacons that are identified by Morse code:

The beacons of Hässlö airport highlighted and the complete airport map.

By tuning in the frequency you are quite certain to listen to the correct beacon. But by confirming the Morse code, you are sure.

During the private pilot exam for LFV (Luftfartsverket), the Morse code skill was tested.

Morse code as a signalman in the Swedish Navy

Hans spent 3 months of basic training, including communication with optical Morse code. The training took place in an attic of a military building in Karlskrona. A pair of students used small lamps with integrated key to communicate with each other, from one end of the room to the other.

Hans is practicing optical Morse code on the torpedo boat HMS Spica T121, 1977. Hans received optical messages from ships and announced them on the internal intercom via his throat microphone.

Illegal transmissions

Since 1988 Hans is permitted to transmit on dedicated amateur radio frequencies. But before that, Hans has made some illegal transmissions as a youngster.

This transmitter was later xxxx.

Home build radio-clock transmitter

This transmitter may be classified as illegal, but since the range is only a couple of meters, it can be regarded as a test transmitter.

Immoral transmissions

Blocking electronic car keys

In the years around 2000, cars are equipped with electronic keys as a supplement, or replacement, for mechanical keys. Many of these keys were operating at the ISM frequency 433.92 MHz which is a frequency that does not require a license.

Hans buys an electronic door bell that operates on the same frequency.
