I bought 4 at random from Victor Tkaschenco, UR7GG in Friedrichshafen this
year. ( ur7gg@tlc.kherson.ua )
I have tested all 4 in mixed configurations in my Acom2000A and got a
consistent output on any combination.
Given the huge amount of scammers on e-bay and the scam-propositions one
receives after bidding I prefer to deal with real human beings with real
addresses and real phone numbers nowadays.
