    I found all three of them
    on an international e-shop platform. Because I'm setting up my Ham radio station in this period, I would appreciate any answer.
    Many thanks 73s SV1DUE

    They're all pretty much the same; Chinese garbage.

    I had once bought one from eBay and it soon went in the trash. Low Q coils, terrible quality caps and relay switches, awful firmware;

    If i were you i wouldn't spend a dime on these. Save your hard earned money for something that is worth it.

    Ευχαριστώ για την απάντησή σου. Ναι, τελικά αμφιβάλλω πολύ αν θα το παραγγείλω. Πάντως ευχαριστώ. Ερώτηση. Η χρήση εθνικών Γλωσσών δεν επιτρέπεται και γι΄αυτό μου απάντησες στα αγγλικά; Είμαι καινούργιος στο QRZ και δεν γνωρίζω τη δεοντολογία. 73ς Χρήστος

    Ναι, η αλήθεια είναι πως ενοχλεί αρκετά και αρκετούς εδώ η χρήση άλλης γλώσσας Χρήστο.

    Τα 73 μου, Θάνος

    If you need a remote tuner (it means your antenna presents more than 3:1 SWR and internal tuner in transceiver cannot handle it), you better get REMOTE tuner and place it NEXT TO antenna. The best tuner for 100W of power is ICOM AH-4.

    Doesn't bother me at all. In fact, Greek is a great language in which to converse. There is no rule, written or otherwise that says you can't use it. The only problem I see with it on this forum is that many can't speak / read / write it here in the US. BUT that is easily overcome with a computer.

    About the tuner: I don't know anything about the three you mention. BUT I do like the MFJ 971 Portable. It works well, and is easy to tune. If there is a vendor new you, it could be a good option.
