I’ve spent some time during the past weeks remodelling my pedestrian mobile chest table (which can also be used in /P situations where tables/chairs etc are not available).

The main aims of the remodelling were
a) To make it lighter and more ergonomic in use
b) to allow the mounting of a CW paddle and/or straight key
c) mount an external speaker to make sure received and transmitted audio are acceptable for recording on an action cam - I intend video documenting my /PM excursions this year.

Today I tested the table in my back garden. I’m pleased to report that it seems fine and fit for purpose. For the test I coupled the KX3 to the small DIY magloop. Despite today’s poor propagation I managed to hear a number of stations on 40m - but could not work any - the loop is very inefficient on 40m even though the added capacitance (coax loop) allowed it to tune quite nicely. On 20m, without the added capacitance, I managed a difficult QSO with a station in Sicily. This QSO was recorded by the action cam. The recording, attached below, was very satisfactory.

Also attached are two photos of the magloop with and without the outboard capacitor. Also attached are two photos showing the arrangements for mounting the paddle and straight key.

Hopefully the /PM chest table will see some action tomorrow (as a /P with the magloop and proper /PM with a backpack fastened whip) when I attend the St. Georges Day special event station GB1STG

I found this little gem on AD5X's website for QRP rigs but im trying to determine if it can be mod'ed to handle more amperage draw than 3 amps and up it to say 30 amps instead. This way i can use a LiPo s4 config with a 16.8VDC max charge on my ft857. I have located cells that can handle the continuous discharge required for my application.

Other than replacing the diodes and relay do i need to mod any of the rest of the circuit? Also what parts would you recommend as replacements. I don't believe i need to mod the rest because its appears to be simply a parasitic circuit with a 26ma draw at 16.8VDC that detects the voltage to operate the relay. If i am wrong let me know.

I now own a working radio station. I pcked up the modest shack from an SK. I should now be able to do the next RaDAR activation day. I do plan on doing some preparation setups and figure out what I need. I saw a video on YouTube on a 55,800 mAh battery/charger pack that is sold on Amazon. I might buy one of those for a portable power supply.

When I get home and have everything sorted that I am going to use for my RaDAR setup I will post it and get some recommendations for additions.

I don't remember if i shared this youtube vid here from my youtube channel. I had shared it on some other ham groups and i think you all would like it as well.
