Portable Aircraft HF Radio Build (Going to Be Long) Multiple Posts....
Hello, Usenet, Jay, Marry, Montblack, And Friends!!!
Since Comcast is so lame and Lost the HF thread will start my own. HF-Box build project, Goal is to simplify next flight T182T to Qatar next week!!! and return airline flight home with equipment not broken. Most all you know what I do for a living fun, fun, fun, :-) yep mostly Single Engine Piston Aircraft Over Oceans it some times requires an HF Radio! Well I got tired of always fumbling with HF wiring Special Flight Permit Allows!! A Power Drop For HF When Tanked!! So I decided to package it all in to one small portable airline carry on size case case. I used a Pelican case just incase I may be harassed and asked to check it as I have in the past (Thanks!! Delta, Virgin, and TSA A-holes) This Case Will Not Be Water Tight It Requires Drilling Holes!!!! Pelican Unconditional Warranty Still Applies Leaving Holes To Min. MADE IN USA WITH GREAT WARRANTY!!! Supply List, Pelican 1450 Case About $75.00 Shipped (No Foam) HF Radio ICOM 706MKIIG 100 Watt $949.00 On Sale Ham Radio Outlet (Remote Mount Kit Required It's UsuallyFree + a $50 to $100 Rebate) Look Here http://www.icomamerica.com/amateur/hf/index.html#706 Automatic Antenna Tuner SGC 237 100 Watt (or 239) $359.00 Astron 24 to 12V Converter 20 Amp 24 Peak About $150.00 2 Nice Size Pieces Of Aluminum ($ Varies Mine Was Donated By Horizon Air Trash Can! Yea, I Dumpster Diving Again!!) A Bunch Of Mics. Items Don't feel like Listing them All Use Your Brain!!! (Jacks PL235 1000UF 25V Cap And 10K Resister, 1 or 2 Computer Fans Etc.) MCM, Norvac, Etc. ($$ Varies) Tools, Tin Snips Left, Right, Straight, Soldering Iron, Solder, Drill And Assorted Bits, Rivet's And Rivnuts...Lots of Heat Shrink, Epoxy, Your Brain, and Harbor Freight If you have a local one!!! (My Case Friends Snap-On Truck & My Own Good Tool Collection) You will need Soldering Skills, An Adult Beverage I Like Whiskey, Kitchen (Aka, Workshop) And AN Understanding Wife!!! For making a Big Mess!!! This Pelican Case will give you enough Space to Pack The Radio, Long Wire Antenna, Tools, And Universal Mounting Hardware Cessna, Piper, Grumman, Etc... Single And Multi All Connections Antenna's. Power, Ground And Control head will be External Mount Quick Connect. Photos Will Be Out Of Numerical Order, The Case, Pelican 1450 Perfect Size About $70.00 No Foam http://www.internationalferryflights...X/S4010546.JPG http://www.internationalferryflights...X/S4010544.JPG Take You Sheet Of Aluminum Cut it To Fit The Bottom Of the Pelican Case. Don't Cut your Fingers....I did not want to use my CNC mill for this to much work to clean the Garage to get to the dam thing. Ok, Mount the Radio Mount To This!!! I Used 1/8" Pop Rivets... http://www.internationalferryflights...X/S4010541.JPG http://www.internationalferryflights...X/S4010542.JPG Verify Fit In Case, Looks Ok! http://www.internationalferryflights...X/S4010545.JPG Remove Frome Case and Mount Radio http://www.internationalferryflights...X/S4010547.JPG http://www.internationalferryflights...X/S4010548.JPG Verify Fit In Case, You want About 1/2 Inch for Cable Clearance On Front Remote Mount Cable. http://www.internationalferryflights...X/S4010549.JPG http://www.internationalferryflights...X/S4010550.JPG Time To Mount The Antenna Tuner, Ok I used scotch bright pads with a right angel die grinder to remove the paint off the bottom of the SGC-237 (No Photo) because if you have not guessed it by now we are using the aluminum sheet as a ground for this project. A good ground with a wire antenna is key for this set up. http://www.internationalferryflights...X/S4010552.JPG Verify Fit In Case, Make Another Adult Beverage!!! http://www.internationalferryflights...X/S4010553.JPG http://www.internationalferryflights...X/S4010554.JPG Find A Spot For Cooling Fan Placement, (I Do Have A Guard For The Fan) http://www.internationalferryflights...X/S4010555.JPG Remove Lid Re Clock 180 Degrees Add Auto Tune Cap & Resister To the Inside Of Tuner At The Terminal Connector. http://www.internationalferryflights...X/S4010559.JPG More Inside the SGC237 http://www.internationalferryflights...X/S4010560.JPG Preview Of Mounting Astron Voltage Converter to lid Of SGC-237 Antenna Tuner, http://www.internationalferryflights...X/S4010557.JPG http://www.internationalferryflights...X/S4010558.JPG Tomorrow!!! Mounting Voltage Converter, And Selector Switch 14v or 28v Systems, Adding External Fuse's, Cutting Top Plate, Adding Antenna And Power Connectors, Airflow Cooling Tests, Etc... You, Want to use Nylon Screws When Mounting the Astron Voltage Converter dure to the High Voltage In The Antenna Tuner. This box is nowhere done I may find problems and Issues along the way and correct...will post trial and error. I will try and be strait fwd as possible.. All input will be accepted. Used?? BBL!!! Photo's Of Diesel 182 Coming Soon Trip to Tanzania is Delayed Due to FAA B.S. Supplemental Type Cert Update From SMA!!! Oops!!! OH!!

When the TSA gobs see this at the airline terminal, you are going to be sooo strip searched... It seems like you have a good grasp on the basics, but let me mumble on a bit here anyway... Don't depend on the negative battery lead as your RF return... Have a short (relatively speaking) lead from your grounding plate with a clamp on the end, to clamp to bare metal on the airframe - a small gauge automobile jumper cable with the clamp, will work nicely... How are you going to lead the antenna wire out of the cabin? It will be RF hot from the connector on the tuner, outwards... I assume it will be a drag wire off a reel or some such... Or will there be an ADF wire from fuselage to fin? In my nefarious past I have been in industrial electronics and I have been an active ham for nearly 50 years, so always glad to obsfucate anything you might want to discuss... You can drop me an email at cheers ... denny - k8do |

wrote in : Airflow Cooling Tests Interesting write-up. Thanks. Personally, I would mount the cooling fan at the bottom of the case (dependent on how you intend to orient it during use), so that it pulled outside air into the case. Then I would provide a hot air exhaust port/register at the top of the case. This arrangement will take advantage of convection to enhance airflow, and may even work in the event that the fan becomes inoperative. But you've probably already considered this. |

Perhaps it would be better to establish a contact within the FAA who can be contacted at check-in time by the airline/TSA to verify Steven's legitimate right to transport such an "interesting" piece of "luggage". |

His right to transport? Good grief. Bertie |

It would probably be better to go visit the boss of the TSA at the closest large airport before he needs to travel and see if he could get a letter or something from him. I don't think the TSA gives much of a damn what the FAA thinks. |

But I already get looks showing up with a bag full of electronics and lots of wires and tools. |

As for an antenna I belive I posted some photos of mounting on a cessna and piper. Here is the cessna 172 Antenna is 3 strands of magnet wire twisted and inserted in to a yellow heatshrink and 1" red was added about every 2'for visibility (hurts to walk in to a wire. With my radio set up it will tune 3-5mhz good on as little as 14' http://www.aircraftdelivery.net/me/HF1ANT.JPG http://www.aircraftdelivery.net/me/HF2ANT.JPG http://www.aircraftdelivery.net/me/HF3ANT.JPG http://www.aircraftdelivery.net/me/HF4ANT.JPG The lead out is high voltage automotive spark plug wire connected to the antenna. |

I don't see any safety wire or other obvious means in the photographs. The lead out is high voltage automotive spark plug wire connected to the antenna. Of course, that high-tension lead has a copper conductor in it, not the noise-suppression type with graphite impregnated cotton cord (or whatever it is), right? |
