There is a problem of electronic components and we are not exempt from this worldwide problem.

The pandemic caused the temporary closure of factories but, above all, with the rise of teleworking, the demand for electronic equipment has multiplied and has caused a real problem of supplying low-cost microprocessors and components in general.

To date we have been able to continue manufacturing and supplying our equipment, although in recent months, we have been forced to have access to opportunistic companies that had stock, with which there have been components that we have had to pay x5 or even x10, but we have also found that there are certain components that are not currently available and in some cases there is no plan “B”. There are some components for which our usual supplier gives us delivery dates of February/2023.

Our usual component suppliers tell us that by 2023 we will apparently return to the previous situation, but what is certain is that during this 2022 being able to manufacture some of our equipment is a complex task and our costs have gone through the roof.

We regret this circumstance and we are forced to report it.

Node-RED is a flow-based development tool for visual programming developed originally by IBM for wiring together hardware devices, APIs and online services as part of the Internet of Things.

Node-RED provides a web browser-based flow editor, which can be used to create JavaScript functions. Elements of applications can be saved or shared for re-use. The runtime is built on Node.js and In 2016, IBM contributed Node-RED as an open source JS Foundation project.

Since October 2021 I have been developing different sub-flows and examples to be able to integrate the different devices as ARS-USB, RemoteBox and StackMain into this great platform to be able to be integrated into it.

Thanks to the excellent work of Jordi EA3GCV who has continued to program and support the popular SWISSLOG program, we have a great integration between ARS-USB and SwissLog.

You can see in this link how you have to configure the SWISSLOG so that the ARS-USB is integrated and is really easy to use.

My friend Tobi DH1TW has developed a new web control that supports any of the RemoteBox models & StackMain through a simple and effective web interface. He has used one of the most innovative programming languages known as GO (see golang) developed by Google in 2009.

One of the many advantages of this programming language is that it allows generating code for multiple platforms (GNU / Linux, FreeBSD, Mac OS X or Windows), which means that you only have to maintain a single source code.

You can read more about this exciting program and its implementation in the following link:

We have received during last months many requests to design and supply a simple FrontEnd Limiter based on our 6xBPF-FEL.

The new RX-FEL is already available, a device to help protect receiver front ends from high level signals when operating in the proximity to other transmitters which could damage the receiver.  Some examples where it is necessary to incorporate these protectors are multi-transmitter contest stations, Field Day operations or when we have a station very close to ours.

The equipment includes a gas discharger that derives high voltages to ground, a pair of diodes that limit any incoming signal to low levels and that can no longer saturate or damage the preamplifier of the receiver and two baluns to the input and output that ensure the impedance.

  • RX-FEL

    The RX-FEL is a RF protector and limiter for your radio receiver or SDR. Installed between the RX antenna and the receiver, it will limited any RF signal and will avoid to damage the receiver because strong signals.

    The RX-FEL is a device that will protect the receiver front end from high level signals when operating in the proximity to other transmitters which could damage it. Situations such as multi op contesting, SO2R or Field Day. 

    • Insertion lost better than 0.4dB in HF (1.8Mhz - 50Mhz) 
    • VSWR < 1.06:1 (reception)

It can be downloaded from the Tobi DH1TW page:

the source code and the binaries already prepared for the different platforms.  

The remoteRotator program in addition to providing a simple and dynamic web interface for the control of the ARS, provides access to the traditional program for managing the ARS: ARSVCOM, so that several ARSVCOM clients and web users can be simultaneously connected.
