[Enrique carbonell madrid]

Hello everyone,

My name is Enrique, callsign EA7LCA, writing from Spain. I’m very glad to join this group of collectors and restorers of U.S. military equipment.

For the past few years, I have been restoring a GRC-142 Shelter station, a project that I am now close to completing. I have managed to acquire almost all the equipment and accessories piece by piece, mainly from the United States. It has been a long and sometimes expensive journey, and many times I ended up buying non-working units which I later repaired myself — fortunately, electronics restoration is something I truly enjoy.

At this point, I am still looking for a few remaining items to complete the station, specifically a TT-76 teleprinter (if I remember correctly the designation) and a J-4024/U crypto unit.

One of the main reasons for my introduction here is to connect with people who might help me locate these final components and possibly assist with shipping to Spain, since many sellers unfortunately prefer not to ship internationally. Any guidance, advice, or contacts would be greatly appreciated.

I also hope to contribute to the group by sharing my restoration experience, technical work, and anything I can learn or help with along the way.

Thank you for having me here, and I look forward to learning from all of you.

Best regards,
Enrique – EA7LCA
Spain
