The difference between S-RockMite and the 51 and PIC versions:
Many friends have reported that the 51 version only stores one set of codes internally, and it is inconvenient to use a laptop code to add reply codes on outdoor platforms. The PIC version not only stores one set of codes internally, but also has a low success rate due to the fact that the PIC microcontroller only has 8 pins and requires key configuration, making it impossible to use the automatic transmission function to send reply codes. Based on these reasons, we (LXQQFY) have designed an S-class radio station (S-class Octopus, S-class Frog Roar, S-class 49er), which is very convenient for configuring data on mobile phones.
Another point to note is that the transmission power of S-RockMite and 51 versions is slightly higher than that of PIC version.
Product precautions:
The welding, assembly, and debugging of individual components require a certain level of electronic technology foundation, with the ability to recognize and weld components. There is little need for debugging, as long as the assembly is carefully carried out according to the kit instructions, it can be successfully assembled. If a novice discovers a welding error, Jianyi should not handle it on their own. Please consult customer service for corresponding technical guidance.
1. Introduction
This is a very compact and simple 40 meter band low-power equal amplitude telegraph transceiver, powered by a 9-13.8V DC power supply, which can communicate with amateur radio stations hundreds of kilometers or farther away. Its reception effect is very good, comparable to expensive commercial radio stations.
There are many versions of 'Rock Mite': the initial version (SWL Laboratory, USA), PIC version, and 51 version. Super Octopus (S-RockMite) "is the latest release from LXQQFY.com, with the
following improvements:
Changing the vertical packaging of resistors to horizontal packaging has solved the long-standing problem of resistors being prone to short circuits.
The power input does not distinguish between positive and negative poles, and improves the power supply range. Users can easily use 13.8V communication power supply without worrying about losses caused by reverse polarity connection.
Standard acrylic shell, easy to assemble, beautiful and practical.
Supports WIFI module (optional), automatic key function, and automatic transmission function.
It can be connected to a mobile app to configure data such as transmission speed, sidetone tone tone, automatic transmission content, and display transmission timing. Abandoning computers and facilitating outdoor scaffolding.
You can also use a mobile phone instead of a keyboard to control the radio station to manually transmit messages.
