Byggeprosjekt: Transceiver module for CW og WSPR

By |2017-11-25T16:06:15+00:0025.11.2017|Aktiviteter, Digital, HF-SEKSJON|

Eg håper å kunne lodde stemmning for deltakere for eit byggeprosjekt for å sette saman eit radio transceiver module for CW og WSPR for eit band. 80, 60, 40, 30, 20 or 17m bands; dreibar tuning, to VFO, A-B; CW decoder; morse øvings generator, innbygget test utstyr.
Men den ha så mykje meire utover, les sjølv—-

  • Easy to build, single-board design, 10 x 8cm, all controls are board-mounted
  • Professional quality double-sided, through-hole plated, silk-screen printed PCB
  • Choice of single band, 80, 60, 40, 30, 20 or 17m
  • Approximately 3-5W CW output (depending on supply voltage)
  • 7-16V recommended supply voltage
  • Class E power amplifier, transistors run cool… even with no heatsinks
  • 7-element Low Pass Filter ensures regulatory compliance
  • CW envelope shaping to remove key clicks
  • High performance receiver with at least 50dB of unwanted sideband cancellation
  • 200Hz CW filter with no ringing
  • Si5351A Synthesized VFO with rotary encoder tuning
  • 16 x 2 blue backlight LCD screen
  • Iambic keyer or straight key option included in the firmware
  • Simple Digital Signal Processing assisted CW decoder, displayed real-time on-screen
  • On-screen S-meter
  • Full or semi QSK operation using fast solid-state transmit/receive switching
  • Frequency presets, VFO A/B Split operation, RIT, configurable CW Offset
  • Configurable sidetone frequency and volume
  • Connectors: Power, 3.5mm keyer jack, 3.5mm stereo earphone jack, BNC RF output
  • Onboard microswitch can be used as a simple straight Morse key
  • Built-in test signal generator and alignment tools to complete simple set-up adjustments
  • Built-in test equipment: voltmeter, RF power meter, frequency counter, signal generator
  • Beacon mode, supporting automatic CW or WSPR operation
  • GPS interface for reference frequency calibration and time-keeping (for WSPR beacon)

 Eg ha 2-3 moduler for 40m på veg til meg no.

Byggeprosjekt “The Morse Phone 2017”

By |2017-11-25T16:02:00+00:0025.11.2017|Nyheter|

The Morse Phone is a morse sounder which you can use to start playing with morse code. The assembled kit can work independently, or in a network together with one or more other multiple connected units, and can also expand with a separate 433MHz RF module.

The Morse Phone can be used to get started with the Morse code. You can use him to practice, but you can also pair two or more Morse Phones and send messages to each other. In the manual there are some suggestions for fun experiments with the Morse Phone, so you can also make an extra Morse key of a paperclip or cloth knife and use it with the Morse Phone.
A separate RF kit will become available so the kit(s) can communicate at 433Mhz.

When two (or more) modules are connected together the one unit will always send to the other(s)

Det er beholdning av disse sett på Bergen Kringkaster til kr. 125,-. Og me har planer om å lage til eit for demo

Vil du være med å bygge? Ta kontakt med Peter

About Bergensgruppen av NRRL

By |2018-11-12T17:49:00+00:001.1.2014|Nyheter|

Welcome to “Bergensgruppen av NRRL”

LA1B is the callsign of the Bergen branch of “Norsk Radio Relæ Liga” (Norwegian Radio Relay League) The club was established as “Bergens Radio Amatør Klub” (BRAK) 25th November 1922, and received its present callsign in 1949. The club is open to all and sundry with interests in radio communication and radio technique in general.

Regular meetings are held every second Monday through the year (see the calendar) Organized talks are generally given on the Mondays, and can also be set up at other times, to suit the presenters.  A few meetings each year are held near the city centre. Announcements are given in the calendar. Weekend activities are also announced here.

The club building is situated at Totland, a place south of the city of Bergen in a rural setting 300m about sea level. We have antennas for most bands, ranging from 160m to 70cm. One important benefit is that there is not too much human generated noise affecting this site. The building has a lounge, a kitchen, a couple of small bedrooms as well as a well-equipped radio room or shack. These facilities make contest activity easier.

Although there isn’t direct road access there is parking close nearby and the members enjoy the short walk to the club building. Please see section about “public transport” and “parking and how to get there”

The club holds a training course early each year leading up to the test for the license in April-May. These course evening are held in a locale closer to the city. The course is open for recruiting and the book used as basis for the course is titled “Veien til Internasjonal Radioamatørlisens”. See information about the course and the book here

The Club also has an emergency communications section (Sambandsgruppen) who are building up a mobile control room/depot room (in 2018). Equipment is cached in preparation for any call-outs as well as the personal equipment sets belonging to the individual amateurs. And permanent antennas have been installed at a couple of key sites. Exercises are called regularly.

The club has regular contacts with neighbouring clubs and smaller groups, for example a sub-group is being encouraged in Hardanger. Sotra DX Club also comes into this category. And a co-operative project is being started with the Haugesund-Karmøy group, this will hopefully spread to other groups as well in due course.

Please feel free to contact the club address with any queries or requests.
You can use the contact-form page or look at the contactslist for more specific contact persons.

Please come along if you are at a loose end in Bergen, we look forward to making your acquaintance.

LB0K/G8CKB, Peter
