REPARING RADIO TRUTH

Dear Friends of Radio Truth:

May I inform you that, beginning yesterday, Thursday December 3, 2009, and the whole day today 4th, we have worked very hard on the reparation of the first short wave module of Radio Truth, with the Technician Angel Custodio Santos. Yesterday morning, I made new electrical installations exclusively for our transmitter, because there were happening strange electrical troubles during the last tour days, for which reason we had come off Internet during three days. On Thursday afternoon, there arrived the Technician with his brother, and we started to review the transmitter’s base. The first thing we discovered was a TOTAL short circuit on the “sparker” defense, the place where the antenna is connected. Both electrodes were melted together. We separated them, and calibrated again. See two of the photographs attached (probably on a following e-mail). I suppose this was the cause why the other module exploded the previous time (several months ago). But, we continued on the revision, and found some other integrated circuits damaged, and substituted them. We had substituted a bipolar diode also, for which it was difficult to find a spare, but we installed the same of an older module. When everything seemed to be alright, we decided to introduce the module into the transmitter in order to make a first test. I turned on the first phase (low voltage), and everything seemed to be alright. But, when I turned the high voltage on, a rely reacted, and cut off the energy. We couldn’t continue with the process. Then, we left the transmitter on without the high voltage for a while and, took off the module to be analyzed. After touching all the parts, we discovered two integrated circuits (voltage regulators) extremely hot. That was the final trouble. But WE DIDN’T HAVE THOSE PARTS AT HAND, and we had to desist. All parts for our Omintronix 1000SW transmitter, are very difficult to get in all the World, and every time we have to find someone to factory them in the United Status. That may take some months.

Now, we are in the efforts to get, as soon as we can, those two integrated circuits (voltage regulators), in order to substitute them, and try again. We trust in God that this one may be the last trouble to solve, in order to return on the air.

In case somebody would have the means to get such parts (both the same), they are identified with the following number: P3055V

Many thanks for the interest you have demonstrated in order that Radio Truth may come back on short wave. We authorize you to publish this information, which we appreciate very much.

May God bless and keep you.
