| Kenpro KR-400 arrived by EMS (2025/11/19) | ||
|---|---|---|
| I was looking for a horizontal rotator for satellite communications. I found a Kenpro KR-400 on Yahoo Auctions that had unstable meter readings, and it was a bargain. The bid was successful for 15,000 yen($96). I asked a friend in Yonezawa City, Yamagata Prefecture to send it via EMS, and it was delivered to the Philippines in 45 days.  |
||
| Disassemble the KR-400 to replace the potentiometer. Disassemble the bearings in the box to prevent them from falling out. After disassembling it, I found that it was better to remove the bearing housing with the bottom side facing down after removing the bolts. Bearings do not fly off  |
||
Remove the five screws and you'll see the potentiometer. |
||
Since I had disassembled and serviced the elevation rotator KR-500, replacing the potentiometer on the KR-400 was easy. |
||
| Now I have the elevation rotator KenPro KR-500 and the rotator KR-400. The KR-500 was available for 1,000 pesos ($17), and the KR-400 was available for 15,000 yen($96).  |
||
| I purposely chose a controller with the same design. On the left is the elevation rotator KR-500 On the right is the Rotator KR-400 Above is the rotor controller Fox Delta's ST2-USB  |
||
| The ST2 connects to the KR-500 via an 8-pin DIM connector. From KR-500 to KR-400, use a 5-pin DIN connector I modified the case and attached the connector.  |
||
| The Fox Delta ST2 is a 5V open collector, so it cannot turn an AC motor on or off. Therefore, I created a circuit to control the rotor motor with a 5V relay. For detailsOctober 13, 2025.Please see the diary.  |
