K3NG Arduino CW Keyer K5BCQ Board Build Part IV

     Due to health issues, the holidays, and waiting on ordered components to arrive this project is going slower than the speed in which most people would do. I don't have an endless supply of parts just laying around the shack. So we will continue as we can. 

    I redid the picture showing what components that have been soldered to the board. I decided to simply color-code each type of component. I have found that this is easier to find parts that I have missed. Again I am not an EE (Electronics Engineer) I'm just an amateur radio operator and the word amateur is the keyword, trying to learn this stuff. This morning I finished all of the resistors. You need to pay attention because some of the resistors are rated for 1/8 watt and some are rated for 1/4 watt. 

Here is a drawing showing my progress so far.

Here is a photo showing the same progress as the drawing above.

Next up I will be doing the ceramic disk capacitors. Once you sit down and take a good look at it, there really aren't that many parts to this. The board itself is only 99mm x 87mm. I know for sure that I will be needing the single-row headers and the transistors. When you do order components, you really should order more than you need. The parts themselves are pretty cheap, sometimes the shipping and handling is more than the actual order of the parts. So order more than you need, like resistors. Even if I need only one resistor that is 1/4 watt 100 ohms is only two cents each. Order at least 100 of them and you will use them in later projects. You should just use your best judgement on the number of parts that you order. 

Stay Radioactive until next time

Japan will put QRP Amateur Radio Transmitter on the Moon

    If you are a Starseeker like me then you may well indeed go nuts over this. This is just pretty darn cool. 

    The Japan Aerospace Exploration Agency (JAXA) is tossing together some bits and pieces to make the OMOTENASHI, the world's smallest moon lander. They say that it is the world's smallest moon lander, so is it the smallest on Earth or the Moon, because if it is the smallest on Earth, then it would not be for long because once it is launched, it will no longer be on Earth. Anyway, OMOTENASHI is an acronym for Outstanding MOon exploration TEchnologies demonstrated by NAno Semi-Hard Impactor. OMOTENASHI is a 6U CubeSat (6U refers to the size of the satellite which is 20 cm x 10 cm x 34.05 cm)

    OMOTENASHI is made up of two separate parts, one part will be placed in lunar orbit, and the second part will land on the lunar surface.  The is expected to last just 4-5 days, so now is the time to start to make sure that your shack can receive the signal because it is not going to last very long. The orbiting module will transmit a 1-watt PSK31 digital telemetry data on 437.31 MHz. The surface probe will also transmit a 1-watt signal on 437.41 MHz but it will transmit using FM, PASK31, and PCM-PSK/PM.

    Japan's JAXA does not have a world wide system of listening posts like NASA does, so they elected to transmit their signals on the 70 cm amateur radio band and allow ham from around the world to report if they have been able to receive the signals. Wataru Torii of the Japan Aerospace Exploration Agency Ham Radio Club said radio amateurs can play a role in gathering data from the spacecraft. 

    At this time OMOTENASHI is expected to launch as early as February 2022 using a NASA SLS Rocket. To learn more visit https://en.wikipedia.org/wiki/OMOTENASHI
