Antenna project part II - The tower and antenna installation

As a sequel to Part I of the Antenna Tower Project here's the tower and antenna setup ... - it was a real effort with up to 10 people working on it. The photos hopefully convey how much sweat it cost to almost finish this - the beam still needs two more sleeve element sets being installed - with luck (weather, help from my fellow antenna installers) we should be able to actually complete this by next Saturday ...

The tower is a Hummelmasten Explora 500 and the beam is an OptiBeam OB16-5 . Pretty impressive 30 feet boom and maximum element length (no traps, nowhere) of 34 feet. But:

See the pictures below and enjoy!

At 07:00 AM work began ... - Hummelmasten delivers the tower.

Unloading stuff ...

The truck-mounted crane - maximum height 55 meters / 165 feet - came half an hour early....

My father-in-law (red shirt) and a neighbor discussing why on earth this thing has to be so large  ;-)





Mr Hummel, designer of the tower and company owner of Hummelmasten, directing the crane guy how to position the tower ...


Almost there !


Goenninger family (two of my three brothers) at work !





Helga Hummel fastening some screws - Hummel family completely here to install the tower. Besides the work and sweat we had a good time together ...

Mr Allenstein, son of Mr Hummel, getting ready to climb the tower.














The crane controller - funny guy with very accurate positioning of the crane - he had to go to 189% of spec'ed limits to cross the 39 meters distance between point of installation of the tower and the location of the crane on the street ! 

Real teamwork ! ;-)


Family was not enough - our neighbor had to help, too.

Installation of the rotor -  a Pro.Sis.Tel PST-61D .

The 20m reflector and the 12m and 17m sleeves being assembled.


After sunset (around 20:00 PM) we stopped work ...

... it was enough for this day. 

A big THANK YOU to all the helpers (Alexander Schwab, Dirk Goenninger, Marc Goenninger, Marian Goenninger, Stefan Hild) and the Hummel family for the superb teamwork and the incredibly good work results ! There will be a topping-out ceremony with real Ham Radio QSOs to demonstrate the capabilities of my new toys ;-)

73, Frank DG1SBG

SLIME, Lisp, Editing - the lost slime-close-parens-at-point

Once upon a time there was a rich SLIME version that had all bateries included in a few files. Now this old, old version is long gone. The Powers Of SLIME deleted the function slime-close-parens-at-point whose use and benefit is described in this blog post of Bill Clementson . For those requiring this exact feature here's the original code of that function: (setq slime-close-parens-limit 16) (defun slime-close-parens-at-point () "Close parenthesis at point to complete the top-level-form. Simply inserts ')' characters at point until `beginning-of-defun' and `end-of-defun' execute without errors, or `slime-close-parens-limit' is exceeded." (interactive) (loop for i from 1 to slime-close-parens-limit until (save-excursion (slime-beginning-of-defun) (ignore-errors (slime-end-of-defun) t)) do (insert ")"))) In addition to putting this in my .emacs file I have also the following line in it: (define-key slime-mode-map (kbd "

Compiling ACE+TAO on Mac OS X

So, what's ACE+TAO? It's big, it's complex, it's middleware! See more info at http://www.cs.wustl.edu/~schmidt/ACE.html and at http://www.cs.wustl.edu/~schmidt/TAO.html . In trying to compile ACE 5.7.5 and TAO 1.7.5 on my Mac OS X 10.5.8 system I encountered some strange error messages while linking. These were duplicate symbol errors I couldn't really track down to their root cause but was able to find simple cures. For those poor souls also hitting those faults the following list of changes may help: File $ACE_ROOT/ace/Based_Pointer_Repository.h File $ACE_ROOT/ace/Obstack.h Re 1. : File $ACE_ROOT/ace/Based_Pointer_Repository.h I had to comment out the ACE_SINGLE_DECLARATION on lines 82 to 84: /* - frgo, 2010-01-03 /// Declare a process wide singleton ACE_SINGLETON_DECLARE (ACE_Singleton, ACE_Based_Pointer_Repository, ACE_SYNCH_RW_MUTEX) */ Re 2. : File $ACE_ROOT/ace/Obstack.h I had to comment out the ACE_SINGLE_DE

Aloha! Wow - I always refused to have a blog. Now, well, here it is - my own blog. I don't know yet how frequently I will post or what the posts will be about. So, this is the all-in-one-you-must-have-a-blog first post. There's some other places I can be found:  USENET newsgroup comp.lang.lisp - watch out for posts from "frgo". On the ether: I enjoy doing Ham Radio. If you listen carefully on the 20m band (14.000,00 kHz to 14.350,00 kHz) you might hear me under my callsign DG1SBG. I am also QRV on 145.450 MHz in the VHF band in FM. You have to be close to my locator JN48rn though to hear me - it's VHF after all. Hope to CU! Yours truly - frgo.
