Ruspo Relay 1 ( ) is a desktop / workstation application, designed to connect various analog audio devices (e.g. two-way radios, intercoms, remote microphones, etc.) via a local network or the Internet.

This program is popular among both radio professionals and hobbyists thanks to its flexibility and vendor-neutrality. Unlike some other solutions, Relay 1 does not, in general, require any third-party services. However, until recently, as any server-client application, to connect, the server side required a fixed IP address.. It is not a problem at all to assign a fixed IP address within the LAN . And, despite lively forum debates on the imminent exhaustion of white IP4 addresses, it is still not an issue to get an IP4 address from the cable provider or LTE carrier. But, anyway, that imposed certain restrictions on the using of the software, say, in the casual places or in the certain networks.

Now the possibilities of using the program have become even wider. Starting from October 2017, users of the software are able to connect different instances of Ruspo Relay 1 through Remote Repeater service. So, if it is impossible to obtain a real IP address for “server” mode, just contact Ruspo tech support — there is a  Remote Repeater solution for an affordable fee ($9.9/mo, prepaid). For this fee, you get a virtual channel, where may be connected up to 5 instances of the program (probably, located geographically in the very different places and connected to the Internet in different ways).

Remote Repeater service have 99.1% average uptime and may be used for constant connection (for example, if Ruspo Relay 1  works as an Internet bridge (repeater) for two-way radios in different locations.

Installing the LetsEncrypt SSL Certificate, and Arranging an Automatic Renewal

Chrome warning…


There are a lot of reasons to use TLS encryption on a website. Some of them are obvious (e.g. the protection of visitors’ safety), and some are related to the subtleties like SEO and user experience. Many analysts recommend switching to HTTPS because the search engine of Google considers HTTPS as one of the ranking signals. Besides that, new versions of browsers, (e.g. Chrome) frighten visitors of non-encrypted websites, marking them as “unsafe”.

Until recently, many webmasters, bloggers and SOHO business owners used to encrypt their resources with free StartSSL and WoSign certificates. Since StartSSL and WoSign certificates were going to be distrusted by Mozilla ( and Google, and there were no other free options to get SSL for a long term, we have chosen a LetsEncrypt ( option. Since the LetsEncrypt certificate is valid for 90 days only, automation is really needed. A recommended automation tool is EFF’s Certbot ( This utility semi-automatically enables HTTPS on your website, deploying Let’s Encrypt certificates.

Hereinafter we share our own experience on initial installation and automation, briefly.
