Colin Butler from ICQ amateur ham radio podcast shares our ISS / satellite sucess

Radio amateurs at the Chertsey Radio Club have received test transmissions by two satellites inside the International Space Station (ISS)
Early in  July 2017, the International Space Station sent greeting messages in Russian, English, Spanish and Chinese, which were picked up by club members.
The messages were sent during test transmissions from two small experimental Russian amateur radio satellites, known as Tanusha-1 and Tanusha-2. They will be deployed from the ISS during a spacewalk in August.
As part of the celebrations for the 20th Anniversary of Amateur Radio on the International Space Station (ARISS), the ISS sent a set of 12 images using slow scan television (SSTV). The transmissions took place over four days from July 20.
Chertsey Radio Club member James Preece M0JFP was able to receive the signal and convert them into images using a Raspberry Pi 3.

Retevis RT-36 **Robot* Walkie Talkie

Oscar Thomas and Leo Playing with the RT-36 Robot Walkie Talkies at the park. 

The Retevis RT-36 Walkie talkie comes in a set of 2, has rechargeable batteries, belt clip and a really neat double charger (you can charge both radios together from one plug)

Assembly is easy, insert batteries, push the belt clip in place and you are ready to go.
Batteries are hidden behind the belt clip and no concerns that children will get access easily.

Charging is simple, move the robot arm up, insert cable and plug in, few hours is all that is needed for several hours of operation.

As a Parent, I had a concern that the red rubber feet of the robot, could easily be pulled off and therefore swallowed or become potential choking hazard!

The radios have some neat features, you can customise the colour of the screen (7 to choose from)
There is a paging signal, press the power button for a second, you can choose 10 different sounds
You can activate VOX, which means when radio hears your voice it will transmit, useful for smaller children who can't quite press the button
On one of the Robot feet is a small but very bright LED light, which the children found useful when it got darker and at night (kept by the bed)

Thomas really enjoyed playing with the robot walkie talkie, he has autism, but found the radio simple to use and the bright colours and simple design gave him easy access to using them.

Leo and Oscar, both really enjoyed using the radio, they made up several games including using the robot as a Pokemon device (sorry Dad has no idea)
