Χρησιμοποιώντας δυο Aσύρματους σαν Repeater

Η ιδέα δεν είναι καινούργια, και μπορεί να το κάνει ο καθένας διασυνδέοντας δύο ασυρμάτους μεταξύ τους ώστε να λειτουργούν σαν Repeater (Επαναλήπτης) για να καλύψει σημεία που δεν έχουν επαφή μεταξύ τους.

Η σύνδεση γίνεται με καλώδιο μεταξύ της εξόδου του μεγαφώνου του πρώτου ασύρματου  (που ακούει), και του δεύτερου που αναμεταδίδει στην υποδοχή του μικροφώνου του.

Στο YouTube υπάρχουν δύο σχετικά βίντεο αλλά κάτι δεν πάει καλά με την συνδεσμολογία τους.

Setting up 2 Radios as a Repeater

There is a good chance that you have already watched at least one of the following Youtube  videos.

So let’s take it from the start.
Below is the Kenwood type interface, applicable to most Chinese radios our there (Baofeng and Wouxons for sure).

Random Thoughts on the BAO(feng)s

If there was a plan for little green Martians to conquer the earth, they would hide inside the Baofeng (UV-5R) radios and then pop out the same exact moment all around the world.

 

And those being so popular and cheap are two of the reasons for trashing them around the web. But are they…

 

Glorified FRS radios or Incentives for new HAMs?

 

Among the preparedness and survivalist communities the BAOs are prevalent. And I do not think there is anyone that has a second radio and it is not a UV-5R. so even the advanced HAMs among us could not resist the temptation of the cheap and “easy” radio.
