We have received a lot of enquiries for the English modification guides of various equipment. In general the answer is: please read these pages carefully and often, all information will appear here as soon as we get it. Please remember that most software and guides are and will be for phones that were manufactured for the Scandinavian NMT networks. The modification guides may help you to modify equipment manufactured for your local networks, but the software will not possibly work in other versions. If you need more specific info, please keep your enquiries within the following guide lines:

• Keep your enquiry short
• State the following facts from your equipment:
• Manufacturer
• Type number
• The network system where the equipment was used
• The exact frequency band in MHz where the network operates in your country

If you are interested in software design, we can send you the OH5NXO source code package. Just contact us.

We have been very successful in achieving old cellular equipment from the operators lately. There are some key elements to this:

• The action has to be executed from one contact point only. There is nothing worse than 3694 hams, some of them in a largely intoxicated state, phoning to the directors of a cellular company and demanding that they should have a certain type of phone, preferably between known serial numbers, in mint condition and with all possible accessories, express mailed to them ASAP.
• A letter from the national amateur radio society, underwritten by the president, to the directors of the operator company, stressing the fact that converting old cellular telephones for radio amateur use will help the young hams to understand technology and thus it will generate a drive towards professional engineering in later life
• Hams working for the operator companies must be ready to handle the logistics in their spare time to minimize the costs, they should also come out from their own cubicles and help in advertising our hobby to the directors of the company who often do not have an exact idea what radio amateurs do and why
• The clubs receiving the equipment from the operator company must be equipped to handle them in bulk. Nowadays it is impossible for the competitive operators to sell exctinct equipment one-by-one, especially to demanding customers like individual hams. The underwriters of the club must also accept that they usually shall guarantee in writing that the club will make the equipment unsuitable for further use in cellular telephony before they are forwarded to the individual hams, and that the club will not forward any equipment to other people than licensed radio amateurs.

We would like to thank people at Sonera and Radiolinja, both non-hams and hams, for their support to this great hobby.

We have received offers from Topi OH2LRH and Arjen OH2ZAZ for help in translating the documents in English and Dutch. Welcome on board, gentlemen! If you wish a certain document to be translated, please contact Topi (English documents) or Arjen (Dutch documents) directly.

Some links added, mainly to US pages with Motorola and GE conversions.

We have opened a feedback channel for the hams abroad who are interested in using Finnish made cellular and PMR equipment in radio amateur service. Just drop us a note and we'll answer your problems. Don't expect a speedy answer, though, as the service is operated by only a handful of voluntary experts...
