Portable 2m EME Station:

The 2M EME station is coming together. A lot of time and resources has been spent getting the station “dialed” in for the expedition. Anyone who has ever took a stab at EME knows that building a permanent station is a challenge, building one for portable use has a whole new set of challenges.

The 2M station will consist of the following gear:

Up to this point the pair of 9 element yagi’s were positioned vertically using an aluminum cross boom from the M2 Leo Pack kit. Since CY9 will be within reach of many states on 2m meteor scatter, I have decided to modify the antennas and mount them horizontally for terrestrial contacts. This will also allow me to take advantage of “ground gain” during my moonrise and moonsets. I could no longer use the M2 aluminum cross boom so I custom built a replacement which consists of a solid rod of aluminum for the center section ( which the rotor gets clamped down on) and very sturdy and strong fiberglass rods for the actual booms.

Here is a picture of the original aluminum cross boom with the yagi’s in V POL.


Here is the new fiberglass cross boom.


Big thank you to Steve W1SMS for donating his time and mad fabricating skilz modifying the Array and boom!




Here is the completed assembly with the yagi’s now mounted H POL.


Here is the gear in the lab being tested.


The K144XV transverter outputs between 8-10w while the Atlas needs about 14-16 watts of drive for full 1KW output. When running the K144XV at full output I would get about 550w output from the Atlas. I prefer to run about 750-800w, this give plenty of overhead and well within the spec of the amp. Luckily the Atlas has a 6db attenuator on the input!


Here you can see the 100-6, this is a 6db pad.


We replaced it with a 3.75db pad taken from a TV transmitter board.


After the operation we now see 750-800w output ūüôā

Another issue was the K144XV is not very stable on its own. RX was ok until you transmitted.



Serious dog legging during TX. I immedietly ordered up the stability control options from Elecraft for the both the K3 and the K144XV with the ability to add a 10 mhz external signal source. The high stability crystal probably would have been fine but I wanted a rock solid signal over the moon, especially since many will doing all the work to see my traces over 477,800 thousand miles and ~250db of path loss. I wanted to mitigate any issues. The final option was grabbing a Leo Bognar GPS 10mhz clock. This little item is great! 5-19v DC and a GPS antenna will give you two BNC connectors with a stratum 0 locked time source.

Powering the GPS clock via USB is fine but when I tried sourcing from a 12v supply the case became so hot I could not hold it. I decided to simply power from USB.

Some contacts made with the system.



It was fun working my first 2m Expedition! 6Y5AZ

Unfortunately, I could not hack together a working yagi to attempt to make q’s on a single yagi, the feed points were destroyed and not enough element pieces could be assembled with the resources we had with us. Lesson learned: Stronger support for the tri-pod and base. The rotor was also a casualty from the fall ūüôĀ

    1. Hi Jurg,

      Actually that is not correct. We were looking at the possibility of trying to get to ZD7 but unfortunately we won’t make it. Looking at alternate locations.
