ਸਭ ਤੋਂ ਪੁਰਾਣੇ ਰੇਡੀਓ ਸਟੇਸ਼ਨਾਂ ਦੀ ਸੂਚੀ

ਇਸ ਗੱਲ ਨੂੰ ਆਮ ਤੌਰ 'ਤੇ ਮੰਨਿਆ ਜਾਂਦਾ ਹੈ ਕਿ ਪਹਿਲਾ ਰੇਡੀਓ ਪ੍ਰਸਾਰਣ 1895 ਵਿੱਚ ਗੁਗਲੀਏਲਮੋ ਮਾਰਕੋਨੀ ਵੱਲੋਂ ਇੱਕ ਅਸਥਾਈ ਰੇਡੀਓ ਸਟੇਸ਼ਨ ਸਥਾਪਤ ਕਰਕੇ ਕੀਤੀ ਗਈ ਸੀ।  ਇਹ ਪ੍ਰਸਾਰਣ ਰੇਡੀਓ ਵਿਗਿਆਨ ਦੇ ਖੇਤਰ ਵਿੱਚ ਹੋਏ ਉਹਨਾਂ ਅਗਾਂਹਵਧੂ ਕੰਮਾਂ ਦੀ ਅਗਲੀ ਕੜੀ ਸੀ, ਜੋ ਅਲੇਸੈਂਡਰੋ ਵੋਲਟਾ, ਆਂਡਰੇ-ਮੈਰੀ ਐਂਪੀਅਰ, ਜਾਰਜ ਓਹਮ ਅਤੇ ਜੇਮਸ ਕਲਰਕ ਮੈਕਸਵੈੱਲ ਵਰਗੇ ਵਿਗਿਆਨੀਆਂ ਵੱਲੋਂ ਕੀਤੇ ਗਏ ਸਨ।

"ਸਭ ਤੋਂ ਪੁਰਾਣੇ ਰੇਡੀਓ ਸਟੇਸ਼ਨ" ਦੇ ਖਿਤਾਬ ਲਈ ਕਈ ਦਾਅਵੇਦਾਰਾਂ ਦੀ ਸੂਚੀ ਹੇਠਾਂ ਦਰਜ ਕੀਤੀ ਗਈ ਹੈ, ਜੋ ਆਪਣੇ ਪ੍ਰਸਾਰਣ  ਸ਼ੁਰੂ ਕਰਨ ਦੀ ਤਾਰੀਖ ਅਨੁਸਾਰ ਤਰਤੀਬ ਬੱਧ ਕੀਤੇ ਗਏ ਹਨ। ਇਹ ਰੇਡੀਓ ਪ੍ਰਸਾਰਣ ਤੱਕ ਸੀਮਤ ਨਹੀਂ ਹਨ, ਭਾਵ, ਪ੍ਰਸਾਰਣ ਜ਼ਰੂਰੀ ਤੌਰ 'ਤੇ ਵਿਸ਼ਾਲ ਦਰਸ਼ਕਾਂ ਤੱਕ ਪਹੁੰਚਣ ਲਈ ਨਹੀਂ ਸਨ।
