Callum Builds 2025 Spec DXC Expedition Antenna

Callum Builds 2025 Spec DXC Expedition Antenna


PREVIOUS BUILDS:
https://youtu.be/nbBp42bbELo (3-element version)


I used the following element lengths:
40m: 11.2m (as original spec)
20m: 5.02m (as original spec)
17m: 3.83m
15m: (runs off 40m element)
12m: 2.88m (as original spec)
10m: 2.47m (slight cut)
*NOTE* Without 10m connected, I still got a tune on the CW end of 10m band – strange but true!

New Field Coax Distribution Bunker

New Field Coax Distribution Bunker


I finally found a gap in the weather to put up the shed for all the new coax switches and control gear gear – but it needs some work so make it totally rain proof… Easy fix, I’m sure.

Preparing 13 Antennas to 4 Radios – New Project

Preparing 13 Antennas to 4 Radios - New Project


In this video, we pull out the old Coax switching from the antenna field and prepare to bench test 2 x Genius 8×2 4O3A switches together with the 8XAB Switch Matrix box and an OM Module (16 programable relays) as well as their Rotator Genius. The net effect will be 7 Antennas plus another 6 from the RatPak that either station can select as well as 2 rotators that can be controlled – again from either station. But a lot of head-scratching yet to come! Cheers, Callum, M0MCX.

Using Old Ethernet Cables for Controlling Ham Shack Switches


This is to make sure we don’t change antennas while transmitting. Seems easy – but it’s new for me!

20m - When Conditions are JUST RIGHT!


Thanks Hayden! @HamRadioDX I really must do some more early morning DX. This was good fun, beaming VK and ZL (north pole) from UK last November… Then around to 240 degrees for Long-Path VK

Watching the sun go down in England

Watching the sun go down in England


Birds are still singing and the odd aircraft flying over. SOme traffic can be heard between Baslall Commong and Warwick… Other than that, pretty quiet in Warwickshire
