| Repair of elevation rotator KR-500 (2025/10/03) | ||
|---|---|---|
| I bought a Kenpro KR-500 elevation rotator from 4G9JQU for the incredibly low price of 1,000 pesos (2,650 yen). DU9JJY sent it to me via LBC and it arrived yesterday When I tested it, the meter reading was unstable and the potentiometer was faulty.  |
||
| Operation check video. | ||
Now open the rotator housing and find the potentiometer. |
||
| White plastic gears found when disassembling the gear unit. To the right of it is a gear with a potentiometer attached. By the way, when disassembling it, there were only two photos of the gears.  |
||
| There was so little information that it took me about an hour to put it together. I later found out that there was no need to disassemble the gear to remove the potentiometer.  |
||
| However, the screws on the plate where the potentiometer is attached were rusted. The screw head is damaged and I can't remove it. That's when I found the machine shop HI-TRY Recently, I've become able to drive around the shops by myself.  |
||
The HI-TRY shop is fully equipped with drill presses, lathes, welding machines, and more. |
||
| I used ChatGPT to translate the work instructions into Visayan and had the stuck screws removed. Work cost 300 pesos (800 yen) The owner is very interested in 'What is this machine?' 'It's a motor for an amateur radio satellite tracking antenna.': It seems like you don't understand amateur radio.   |
||
| Finally, the potentiometer came out. Made in JapanVIOLET RA28Y25S B500Ω. I removed the cover of this potentiometer and cleaned it with isopropyl alcohol. The resistance value has improved a little, but it is still unstable.  |
||
| So I searched for the RA28Y20S on Shopee, the Philippine online retailer I usually use. The shaft length seems to be 5mm shorter, but it seems like it can be installed, so I ordered it for 567 pesos (1,500 yen).  |
