Tinkertool Für Mac

Posted on

Graduate programsswsmac student group assessment. An Outdoor NO- FRILLS Slim Jim for VHF. To access Ludhiana Repeater from my qth 140 kms away, was looking for a suitable VHF antenna with following properties: 1 . An Omni-directional antenna to get Repeater as well as local hams.

New in 1.53.f (1.53.f40): Updated ImageJ plugin to version 1.53.f40 (Java 14 necessary!) The main view menubar can now be extended if a plugin uses the main menu of ImageJ. Several features of TinkerTool 1.52 have been reactivated in 3.0 and will be available if the tool is started on Mac OS X 10.0. The feature to set the startup and login language has been removed. Basic configuration of Slim Jim is given below. The wave length in Meters for any frequency ‘F’ in Mhz can be calculated as Wave Length (meters) = 300/F (Mhz), considering Velocity Factor of 0.95 for Aluminium pipe, other lengths are Lambda/4 = 71.248/F in meters, Lambda/2= 142.496/F. Gap = 25 mm, S (spacing) =30mm. Global Nav Open Menu Global Nav Close Menu; Apple; Shopping Bag +.

  1. Better gain then other Omni antennae e.g., Ground plane, 5/8 GP, J pole.

3 . Easy to construct, reasonable life for out door use and economical as well. For all these requirements slim Jim fits nicely. It has 3 db gain then a GP, has lower angle of radiation for longer coverage, requires no ground plane radials etc and can be easily made from whatever conductive materials you have !! Basic configuration of Slim Jim is given below. The wave length in Meters for any frequency ‘F’ in Mhz can be calculated as Wave Length (meters) = 300/F (Mhz), considering Velocity Factor of 0.95 for Aluminium pipe, other lengths are Lambda/4 = 71.248/F in meters, Lambda/2= 142.496/F. Gap = 25 mm, S (spacing) =30mm. Feed point will be about 100 to 115 mm from bottom for 50 ohm coaxial cable, to be adjusted for proper SWR. Building Details. For my build I used 6 mm dia TV antenna aluminium pipe. It is available at local hardware material shop in 10 -12 feet length ( 3.04- 3.7 meters approx), costing about 30 ohms per length then. You will require following materials. !. Aluminium pipe 6 mm dia, wall thickness about 0.3 -0.4 mm, about one length 10 feet (3.04 meter)to be cut in to three pieces as per details given and as per your chosen frequency.

  1. Aluminium flat strip of width 10/12 mm and 0.5 to 1 mm thick about 300 mm long for making shortening clamps OR a one foot (300 mm) long piece of the same above pipe to be cut, split and flattened to make a strip for making clamp.
  2. White PVC conduit pipe 1 inch dia (25 -30 mm) 1.5 meter long one pc for slim jim assembly and mounting. Please DO NOT USE GREY OR BLACK COLOUR PVC PIPE. It absorbs RF.

4.Co-axial cable RG58 50 ohms (not longer then 40 feet) For connecting antenna to your rig. You have various choice, a PL connector mounted at the antenna feed point, a small pig-tail of RG58 with PL connector at other end to connect longer RG213 cable ( if required). However it is preferable to have minimum numbers of connectors in the antenna feed lines to avoid connector losses at VHF or UHF.

  1. Cable ties white 100 mm long, M3 screws and nut with washer of SS, Brass or galvanized MS as last choice, M4 screw 50 mm long with nut and washers and one 3.5 mm X 12 mm self tapping screw.
  2. One 4 inch by 8 inches sun-mica board, used for house hold electrical switch board box top, cut and used in Slim Jim assy as insulated mounting!!

Assembly details are shown below for 145.00 Mhz. For other frequency you can calculate the lengths and use.

  1. Make the four clamps first. Two for top and bottom shortening of pipes and two for coaxial fixing on pipes as per the shape shown. Drill suitable holes for tightening screws. The clamps should slide over the element pipe when screw is loose and lock in place when it is tightened.
  2. Cut following sizes from the sun mica board- A. Two pieces of 35mmX 60mm for spacers. Mark the centre. Place the two pieces of 6 mm pipe equal distance from centre on 60 mm side. Drill two holes adjacent to each pipe of 3.5mm dia for cable tie locking. Drill one 3.5 mm hole at the centre. (see the picture)
  3. Cut one piece of 50mm X 100 mm from sun mica board and drill 8 holes as shown in picture for mounting the gap adjustment portion of the antenna.
  4. Cut 3 pieces from 6mm pipe A. Lambda/4 + 12mm(clamp width) –one pc. (0.491 met + 0.012 =0.503 met for 145.00 Mhz). B. Lambda/2 + 12mm – one pc.(0.995 met for 145.0Mhz).C. Lambda/4 +Lambda/2 + 2 X clamp width + Gap- one pc (0.491+0.9827+2X0.012 +0.025 =1.5227 met for 145.0 Mhz).

Cut one pc 40 mm long and split one side to make a tight sliding sleeve on pipe A for adjusting the gap for SWR and reactive impedance matching.

  1. Lay down on floor all the pipes as per picture and fix sun mica boards with cable ties and fix the both end clamps so that the internal lengths of pipe between clamps as per our basic calculated sizes.
  2. Fix the whole assembly on the PVC pipe by a 4mm screw bolted through the PVC pipe and by a 3.5 mm self tapping screw through the centre spacer, as shown in picture. DO NOT forget to insert coaxial cable joining clamps before fixing bottom shortening clamp.

TUNING.

  1. Mount the whole assembly in a clear spot on a terrace or open space so that no metallic objects are there for at least 3 meters around the antenna. You can temporarily mount the antenna by inserting PVC pipe in to sand or earth filled bucket.
  2. Connect the coaxial cable SHIELD to short element side clamp and CENTRE conductor to long element side cable clamp. Position the clamps about 110 mm from inside of bottom shortening clamp. The SWR adjusting sleeve in the gap should be in fully inserted condition on bottom element.
  3. Use a Antenna Analyser or your handy with a SWR meter in series and at low power level feed RF to the antenna. First adjust the coaxial feed clamps up or down for minimum SWR and then fine tune for a minimum by adjusting the gap by sliding the adjusting sleeve .
  4. Very accurate setting of SWR and minimum capacitive reactance setting (desired) can be done with Antenna analyser.
  5. For better performance of the Slim Jim , a common mode choke should be used just below the antenna feed. You can make one by close winding 9 turns of feed coaxial cable 100 mm below the bottom clamp on the PVC pipe mast itself (as shown in picture), or use 4 ferrite clip-on beads on cable.
  6. Now erect the antenna in suitable high spot by clamping the PVC pipe to a suitable metal mast. Making sure that the metal mast is at least ½ meter below the bottom of Slim Jim.
  7. It is observed that as you lift up any antenna above ground the tuning frequency tends to go up few Kcs, due to ground effect, as such you may have to re-tune and re-check the SWR when fully erected for optimum results.

Happy home brewing.

TinkerTool is a freeware application for macOS that allows the user to customise the system by exposing hidden preferences to a graphical user interface (GUI).[1] It is developed by German developer Marcel Bresink Software-Systeme. Its latest release is version 7.4.2, which is optimised for macOS Catalina and many features that came with it.[2]

Features[edit]

TinkerTool gives users access to hidden system and application preferences that Apple has built into macOS, but not integrated into GUI preferences menus. Although users can typically access these through Terminal operations, TinkerTool assembles them and provides a GUI similar to Apple’s System Preferences application for easier access.

By using Apple’s hidden preferences, the application only commits changes that are reversible and affect the preferences of the current user account. Administrative privileges or background processing are not required. The application also supports a reset option to reset all preferences to Apple's defaults, or to the state that existed before using the application.

History[edit]

Initially, TinkerTool worked with all versions of macOS. However, over the years, compatibility with particular versions of macOS was spun off into separate applications: TinkerTool Classic, TinkerTool Classic Generation 2, TinkerTool 4, TinkerTool 5, TinkerTool 6, and the current TinkerTool. Support therefore goes back to Mac OS X 10.1 Puma and later.[3]

Versions[edit]

TinkerTool versions are specific to versions of macOS and are not backward compatible. The program will not work correctly if used with an OS for which it was not designed.
