Motorola SATCOM Terminal LST-5B

When you need to get a message out this is the way to go!

SATCOM/TACSAT Portable Antenna for your own Zero Dark Thirty

The SATCOM Communication system requires a specialized antenna that offers a right hand polarized method for improved reception. The satellites are also geostationary so for better reception you must have the tactical antenna pointed at the desired satellite within your reception footprint.

Thats why you see the comms guy pull out his tacsat antenna and point it where needed out in the field.

A popular antenna is the Dorne & Margolin DMC-120  which offers 6db of gain

My portable version offers similar gain and robustness, however it is not easily field packable. I magnetic mobile mount is still on the drawing board.

Either antenna is ideal for the Motorola LST-5B lightweight satellite terminal

Portable Operations from the Back Deck

Here is a simple easy to grab and go radio set up.

The foundation is the battery box.

I have a 12A 12V  SLA mounted inside and added a 4 pole anderson pole on the side.

I also added a 3/8" female stud antenna mount and ground/radial binding post. I can now connect my Buddistick or Hustler RM17 antenna to the box.

In order to accommodate the Elecraft KX3, I made up a shelf assembly and added a front foot to stabilize the box.

My list of improvements are to:

 Add a higher capacity battery to power a FT857D possibly
Add a USB socket with voltage monitor
Add a collapsible antenna that fits in the box
Add a magnetic mic holder
Add a light for night time log keeping and operating

ITALY - Private MW legal in Italy.

Private MW legal in Italy

To The Community Amateurs Radio, Shortwave Listeners, lovers of radiolistening DX and
Broadcasters of stations in Medium Wave Band.

Dear Friends, I have the very pleasure to inform you that, in the History of the Italian Radio, today
- 18th August2015 - has borned a star ! In fact the scene of the radio band “Medium Wave” from
Italy, today is a turning point. After 11 years since the beginning of the switch-off of historical
transmission plant in mid wave of the Public Service of RAI broadcasts on a radio band (MW)
that has made the history of radio, will no longer be confidential or restricted to public service but
they will be free to be privately operated. This opens the way for an interesting world in which
broadcasts Band "Medium Wave" will become the protagonists of a NEW media and the future of
the radio hobby. This is the first, interesting milestone reached by the new Law nr. 115 of 29 July
2015 which will open the door to new radio operators <private>.
I wish inform you that a more detailed presentation of this initiative of the Law, is available on
the web: . (italian version). The ARI is supporting this initiative and for the
protection of an important band in the history of radio, is in first place in the development of a body
of opinion to support transmissions in Band "MW". I invite everyone to read the web page on the
website recommended ARI: . (Alfredo Gallerati , IK7JGI, A.R.I Italian Amateur
Radio Association via Mediumwave.Info)

HAM FAIR 2015 - Alex PY1AHD and Japan MLA-48 Group

I was lucky to meet Alex (PY1AHD) at Pacificon 2014 and he was hanging in the HRO booth. I owned his antenna and it does work very well. He did mention something about Ham Fair. Well he did attend as a reporter and ham on the street and antenna manufacturer  of the Alex Loop fame and had his excellent antenna as part of the Yaesu-Musen booth.

Alex has been a tireless supporter of QRP and Magnetic Loop antennas

Our buddy Phil AD5X does a nice review of the walkham

Wimo has a nice page

But check our Alex's web page and operating ideas
