This of course leaves the inside completely free to carry the essentials. So far I have managed to pack the water bottles, mast and VX8 hand-held radio to the outside of the pack with specifically designed pouches.
Meaning that you can purchase extra modular pouches, cases and attachments to the outside of the pack. One big advantage of this pack is the MOLLE (Modular Lightweight Load-carrying Equipment) strapping that the back pack has all over it. I decided to go for the 5.11 Rush 24 which has a capacity of 34 litres which is pretty much the same as the previous pack, but this one has may compartments and sections to store the kit. They have 3 packs designed and named the 12, 24 & 72.
BUDD CHURCHWARD MORSE DECODER FULL
The previous pack was excellent initially but I quickly understood its limitations and when full of kit I realised that everything essentially falls down to the bottom and makes the pack really quite uncomfortable to carry.Īfter much research I noticed a few reviews of the 5.11 rush series. Its been some time since I bought myself any new toys but the two purchases I have made really are for when I am QRP with my go pack.įirstly I have changed the rucksack I use. In the next post – I show the LM567, the schematic and give you the list of parts required. This project covers all 3 areas, and only lightly covers each subject area. I wĪnt to create a project that would “inspire” young electronically minded students that might have an interest in radio – (i.e the morse code) some coding experience and some construction / electronic interest. I will go into more technical detail on the next post – but for the reason why I wanted to complete this ? very simple. This did indeed take quite a lot of chasing and head scratching. I used the limited shared knowledge and discovered that the electronics is basally a LM567 – Tone decoder chip that (I have since discovered the chip is used in the ARRL book for Arduino Projects) I discovered takes an audio input and converts this to a HIGH / LOW output suitable for the Arduino to use as a signal for decoding.įinding a suitable project for the LM567 and trying to work out how fellow constructors had configured their LM567s was not an easy task. I ventured further and wanted to know what electronics Budd was using to achieve this excellent little project. I stumbled across a video on YouTube where Budd Churchward showed his Arduino copying and decoding CW straight off the HF band and at a reasonably high speed. I have a number of reasons why I want to combine radio, Arduino and some electronics – more about this later. I recently started looking at some projects that I could get my Arduino Uno involved in with the radio hobby. So, for those who have not been following me on twitter – here is the sales pitch. After a number of retweets, and favorites from other very interested hams – I did promise that I would collate all my knowledge into a blog posts and share the details with you all. If you do follow me on twitter (and if you don’t – you really should) you will have no doubt seen my recent tweets about constructing a CW decoder.
