Preparation for satellite communications: Elevation rotator KR-500 acquired (2025/09/25)
An elevation rotator required for satellite communications setup.
The YAESU G-5500DC costs over 80,000 yen, so I can't afford it.

So I was searching around and my satellite communication mentor DU9JJY told me 'There's someone selling it, so get in touch'

4G9JQU, who lives in Cotabato, Mindanao, the same place as DU9JJY, has agreed to sell it for 1,000 pesos (2,650 yen).
I'm currently negotiating the price at 'I'm willing to sell this 430MHz cross Yagi, but how much would you buy it for?'.
Is 1,500 pesos (4,000 yen) too much?
Apparently there are no U-bolts or mast hardware.
DU9JJY had some spare parts and offered to sell them to me.
Genuine Kenpro KR-500 Made in Japan.
Video of the operation.
It might be a little loud.
Once you get it, you'll need to do some maintenance such as greasing.
Also, when you turn it from 0 degrees to 130 degrees in the latter half of the video, the display suddenly changes to 0 degrees at around 130 degrees.
The potentiometer may be faulty, but since it is normally only used between 0 and 90 degrees, it may not cause any real harm.

The payment is to be sent to 4G9JQU on October 1st.
Well, it was a great birthday present for someone born on September 25th.
I'm now 66 years old.
