Peter ...

Just curious about a few things: 1) how long was your random wire antenna; 2)  in which direction was it pointed; and, 3) what are the specs on the binocular balun?

I've recently put up a 107 foot/ 32.6 meters random wire; it's pointer roughly Northwest; terminate with a 9:1 balun from WiNRADiO.

I didn't measure the wire but it is about 18m. The balun is homemade with a 9:1 ratio. A wire is non-direction on MW at that length, but it is aligned NW/SE.
You terminate a long wire with a resistor not a balun.

1) Wow.

2) I bet the station would love to hear your report.

Another Peter

Thanks other Peter.
I've never collect QSL cards.

Hello Peter ...

Totally forgot to congratulate you on the 9.4 kmile DX. Like, WOW! That is awesome.

Probably poor terminology on my part. No, the antenna is not terminated with a 9:1 Balun; it's terminated with a "dog bone" insulator. The antenna is attached to the coax lead in with a 9:1 Balun. Hoping that makes more sense!

Thank you for writing back; very much appreciated!

... John

Thanks Ola.

Thanks John.
A resistor terminates a long wire to the ground. That makes it uni-directional. An insulator and a balun don't make a wire directional.

WOW. Very impressive!

Thanks Tom.
