| Welcome to our web site, this is
my attempt at writing a few lines about my
membership in a radio club situated in a colder
part of Northern Europe. NRHF as it is called in
Norwegian is situated in Oslo, however I live
midway between Bergen and Trondheim out on the
coast near a place called Ålesund. The club has
drop in meetings nearly every Tuesday, field days
are as often as possible but usually 2-3 times a
year. We also have auctions at the clubhouse a
couple of times a year. Being situated minutes
from Ålesund it would entail a days drive each
way to participate at a club meeting, 16 + hours
of driving. Thank goodness we have Internet! The
aim of our club is to preserve radio equipment
that has or will have a historical interest for
future generations. During W.W. II a lot of
fortifications were built in Norway, these were
equipped with electronic equipment which was
indeed cutting edge technology at the time. Even
today some of these items turn up occasionally
and are extremely valuable, fetching high prices
at auctions. Since the W.W.II fortifications in
Norway were almost exclusively equipped with
equipment of German manufacture, many radio
amateurs cut their teeth on just such “Army
/ forces Surplus equipment.” After W.W.II British and US manufactured surplus found its way to Norway, Norway despite its modest population has also had a long tradition of producing quality radio and television equipment. Tandberg and Radionette are just two names that come to mind, the list of others is quite significant. Our club has schematics appertaining to most of the domestically produced sets of Tandberg and Radionette, also information about many of the other sets produced under license for other manufacturers such as Philips. (think I am correct in saying?) I am thankful that Internet has enabled me to participate in club activities, we have information on domestic radios mentioned above, and information online about W.W.II valves (tubes) as used in equipment of German origin. From the club I have obtained some parts for a replica of the Olga suitcase radio used by the Norwegian resistance movement during W.W.II, and some of the parts for a valve / tube short-wave radio that hopefully is pictured elsewhere in this article. My interests are centred around both restoring and constructing replicas of older radio equipment. I feel that despite using a lot of time and energy on producing a replica of top quality it will still only be a replica. My Olga project will include a few discreet modifications to allow it to be better suited to usage in field day events, more of this project another time. ( it wont strictly speaking be an Olga!) Our club has recently started a chat room or discussion forum for radio topics, at present in Norwegian but in the future who knows? Many Norwegians are capable of several languages, many club members are radio amateurs and have current call signs. I am an exception to the rule, bad memory inhibits my learning Morse and therefore construction and restoration are my key interests. I wont say that I write just yet. A few details around my Valve short-wave radio project, it will probably use 12Volt valves / tubes similar to 12BE6, 12AQ5 etc this so that it can be easily run from a 12 car battery if need be. By swapping the valves for 6 volt versions it may also be used on 6 Volt supplies. The metalwork will enable it to be built into a rack system so that it may also be combined with a valve transmitter (what else?), alternative power supply units for mains 220Volt. Aforementioned 12 Volt car battery / AGM type battery power supplies will be plug-ins. The transmitter will be capable of telephony and or CW. Internet is peppered with circuits together with pictures of “glow-bugs” and regenerative receivers, hopefully next time I can post some pictures of my progress. Metalwork is cut and folded, most components are rounded up, just the Inductors and transformers to reckon out and wind. I have some suitable laminations and formers in my junk box. Seasons Greetings Anthony NRHF |
