New product from MicroHam (ARCO Modern Rotator Controller)

ARCO

  • ARCO is a modern rotator controller designed for reliable operation with virtually any rotator ever made, commercial or home brew.

  • ARCO provides many unique, present day functions not yet available in any other controller. Rotator motion is carefully controlled using auto-adapting, smoothly graduating/decaying speeds whch reduce inertial stress and prolonging the lifetime of the rotator, antennas and tower.
  • Built to last, built for security, built for total satisfaction!

ARCO is a completely self-contained stand alone rotator controller not requiring computer or any external device or power supply for setup and operation, while providing a wide selection of interfaces for remote control when necessary. It features several ways of controlling azimuth or elevation heading using an uncluttered graphical user interface on the 7” touch screen. Azimuth heading is displayed on a great circle map, user centered to the rotator installation location, with four different radius settings, live grey line projection, several coloring options and automatic day/night color schemes. The controller supports Touch’n Turn feature, the fastest possible heading entry by simply touching the desired direction on a great circle map. In addition, ARCO has the traditional front panel CW and CCW buttons; Point and Shot knob; and heading entry via keypad (either a virtual touch screen keypad or (optional) USB keypad connected to the USB host port).

In addition to manual control, ARCO offers rich connectivity: standard RS-232 port, USB serial port with no driver required on Windows 10, macOS, and Linux, and an Ethernet port to enable control over Internet.

For rotator position feedback, ARCO supports wide range of absolute and relative sensors including rheostat, potentiometer, reed contact, Hall sensor, and PWM sensor. An additional digital sensor port provides three differential lines supporting RS-485 communication, a single ended push-pull, and open collector connections for various quadrature encoders. With high resolution sensors ARCO’s accuracy is better than 0.1º.

For motor control, ARCO uses a high current, 4-channel, PWM driver with overload, short circuit and overheat protections, combined with an automatically operated, current limited internal power supply to prevent driver damage caused by operation failures. This combination is capable of safely driving any DC motor up to 48V or any AC motor up to 24V, including brake control.

Motor start and stop uses configurable, gradual speed ramps to significantly reduce inertial stress to the rotator, tower and antennas prolonging their lifetime. Gradual speed control uses an auto-adapting procedure whch takes into account variable dynamically changing resistance caused by wind or ice.

The built-in control power suppy is linear for silent, interference free operation. The separate, internal motor power supply is turned off entirely when motor is not turning to avoid causing interference to sensitive receivers. For high voltage or high power motors, ARCO provides common control outputs for inverters and industry standard MODBUS RTU control. All rotator settings, including compensation for power loss in the motor cables, are menu driven to allow changes without the need to open the case or change internal wiring.

Networking is another strong point of ARCO. ARCO supports not only LAN networking it also provides a simple yet powerful, isolated two-wire local LINK bus to couple multiple ARCO controllers together for automated stack tracking; multi-directional beaming; and counter rotation for rotating towers. A unique feature of ARCO is a direct control of rotators connected to another ARCO controllers located either on the same LINK bus or anywhere in the world using Internet connection. All this complex control is greatly simplified with just two, easy to use SYNC and ALIGN buttons and a single ANTENNA button which allows the choice of: one of three antennas installed on the same rotator with different heading offsets; any other antenna present on the local LINK network (other ARCO controllers); or another ARCO controllers conncted over the internet (along with any other controllers on its LINK network).

For unattended remote operation, ARCO offers an autonomous parking function and physically disconnects all wires coming to the rotator port from the rotator hardware when connection is closed; breaks; or if ARCO goes to the power down mode in order to minimize possible damage by high static or nearby lightning during storms.

Firmware provides wide range of additional protections and self explaining error messages for quick troubleshooting in the event of failure. All of this housed in a copact, aluminum enclosure with always free firmware updates.

3A/IW1RBI – Activation from the Principality of Monaco

JW0W SVALBARD DXPEDITION NEWS @LA7GIA #jw0w

Ken, LA7GIA, posted the following on FaceBook, May 21st :
“Unfortunately 2 operators had to withdraw due to personal reasons, but we have managed to replace those and hope to be 6 operators when departing in July. Going to Prins Karls Island in JW requires a dedicated expensive vessel that will transport us from Longyearbyen to the island located in the nature reserve at the west coast. Last activation of this island was in 2001. When arriving we will be doing dinghy landing with all equipment. The 3Y0J team members will do some additional practice runs with the dinghy We will focus on NA and Asia outside the IOTA contest, and we will do all modes CW, SSB and FTx. Our antennas will be VDAs and verticals at the shore close to saltwater with excellent take-off in all directions! Due to the high risk for polar bear all over the island, we will have mandatory 24/7 polar bear watch. We will have several rifles, flare guns and other protection. Safety is a high priority and all team members will do training at a local shooting range.
Our budget is roughly 13,000 USDs and we will appreciate donations via PayPal to: jw0wpk@gmail.comThank you for supporting this trip! All the support will go to offset the expensive vessel cost! 73, JW0J team”
* Erwann, LB1QI, posted the following on FaceBook, May 21st [edited]: New members onboard — We are very happy to welcome Allan Batievsky, EA3HSO, and Ronny onboard our Dxpedition to Prins Karls Forland (EU-063) between the 21st and the 26th of July 2021.
Allan, a well experienced contester and Dxpeditioner, will join the operators and Ronny will be in charge of our Security while on the island as the risk of being greeted by polar bears at some point of our stay is high. We will all have polar bears watch duties but he will keep the security at a high level while we concentrate on maintaining the antennas and contacting you! Both fellows are a great addition to the team.We have an internet website (still in construction) but helpful should you wish to learn more about the team or support us: http://www.jw0w.no
Current list of operators now are Allan/EA3HSO, Erwann/LB1QI, Harald/LB2HG, Gjermund/LB5GI, Ken/LA7GIA, Peter/LA7QIA
and Chris/LA8OM. The JW0W FaceBook page is at: https://www.facebook.com/groups/288876866220488

KH6, HAWAII (Update/Special Event).

Several Hawaiian Amateur Radio operatorswill activate the special event station K6K to celebrate “King Kamehameha the Great and Hawaii’s Rich History” on June 11th, between 06:00am HST – (1600z) until 10:00pm HST (0600Z). Excerpts from a press release by Michael, KH6ML, states [edited]: Amateur Radio Operators will activate special-event station K6K to celebrate King Kamehameha the Great and Hawai’i’s rich history. K6K special event station will give HAMS a chance to add Hawaii to their logs to earn WAS or DCXX awards.
Successful radio contacts are eligible to receive a special and inscribed a certificate bearing the full-color rendition of K6K: King Kamehameha Celebration.
After hearing about the cancellation of all King Kamehameha Celebration parade events statewide, Michael Miller – KH6ML , a community emergency coordinator, spoke with amateur radio operators and a few people with the Commission to see if there was a level of interest to make the event happen.
This station is authorized by the King Kamehameha Celebration Commission as an official event.
The Kamehameha Day Holiday was proclaimed by King Kamehameha I’s grand- son, Lot Kapuaiwa – King Kamehameha V, in 1871, followed by an inaugural celebration of events on June 11, 1872. Years later, in 1939, the Com- mission was formed under the Hawai’i Territorial Legislature.
