Michael Schumacher Collectible DNT HT

Old en new accupack

A week ago I found my old DNT walkytalky on the attic. It has been there for years and the accupack was broken. All connections were green of corrossion and the batteries itself leaking. So I made a new one from some 1,2V 2600mAh reacharables. I think this is a special and so a collection item as it seems it is part of a Michael Schumacher CB radio series. Now the only problem is the LCD channel readout, it has been leaking as well and the readout is not complete.



So if time allows I will search for a new LCD. 73, 19AT593 Sebastian

VCO modification

The famous NATO 2000

Long time ago I was in the possession of a NATO 2000 CB radio. It was a unique radio as it offers UK channels besides several bands of 40 channels. It was also a all mode radio and probabely illigal to use. Anyway, the radio got a problem from one day at the other. Receive and transmit refused to work after about 5 minutes of use. I had sleepless nights about this problem as no one could tell me how to solve it. Since I had a manual to repair cybernet radios (this was one) I could measure some voltages and since I got no reading of those of the VCO I thought it was a defective voltage regulator. But after replacing it everything was the same, nothing changed. Replacing several caps besides to VCO that I did not trust didn't do the trick either.

VCO block

So it must be the VCO block. Luckely I had a neigbour station who had a radio with the same cybernet print, the radio came from a car that was driven into water. But according to him the VCO was still intact as it is watertight. I replaced the VCO block with that one and the problem was solved. Years later I found this modification in a dutch magazine called CB Radio. I thought it could be handy to scan the article and place it on the internet.
