Earlier I abbreviated Standiford Field (now Louisville International) as SFD.
In rereading what I wrote I remembered SDF is the old 3letter id.

As hard as I try I guess I will never acheive Mister Know It All status.

O.K., Anymore post about this topic will be in Aviation.

I read it as SDF so I knew what you meant. I am not even sure what the new abbreviation is, and I am a little surprised they changed it.

It's still SDF ...

You may be a bit confused as that is the IATA-naming, while the ICAO is KSDF.

"K" means an airport in the USA, and they just prefix the IATA-code with it.

In other parts of the world it's different, for example:

Brussels IATA > BRU ICAO > EBBR (EB > Belgium)
Amsterdam IATA > AMS ICAO > EHAM (EH > Netherlands)
London Heathrow IATA > LHR ICAO > EGLL (EG > Great Britain)
Paris De Gaulle IATA > CDG ICAO > LFPG (LF > France)
Frankfurt IATA > FRA ICAO > EDDF (ED > Germany)
Madrid IATA > MAD ICAO > LEMD (LE > Spain)

Etc etc etc ...

OK, for some reason I thought they changed it during one of the
renamings but I was mistaken. Thanks for the clarification!

Ed,

Thanks to Ward I learned something in his post.

Oops ... I did something valuable? <swallow>

Well, some clarification.

The IATA-codes are issued by the International Air Transport Association.
It's the trade association for the world's airlines, some 370 with varrying numbers. But not all carriers are a member. It sets technical air-safety standards and assigns the 3-letter airport codes used in reservation systems. One of the problems here is that it allows for a theoretical maximum of 17,576 airports, but in reality that is significantly less as certain combinations are not used.

The International Civil Aviation Organization (ICAO) is one of the UN agencies that manages the administration and governance of the Convention of Chicago (1948, I think, which structured world aviation). It uses 4-character codes where the firstone is a global locator, the 2nd the country, and the 2 remaining a 2-character airport code withing that country. It is less flexible than the IATA-code as "K" is the global locater for the USA and "C" for Canada supplemented by the IATA-code. So you have KJFK for Kennedy airport, KLAX for Los Angeles, CYYC for Calgary, CYYZ for Toronto etc ... also re: the second position there would only be 26 countries in the world, so that doesn't work either.

There's also a third code possible, the "WMO" ... World Meteorological Organisation if the airport has a weather station (not all airports do). The code consists of 5 digits ...the first digit gives the region: 0 to 1 for Europe, 2 to 3 for Russia, 4 for Asia, 5 for the Far East, 6 for Africa, 7 for North America, 8 for South America and Antarctica, and 9 for the Pacific.

So for example 72295 is the WMO-code for LAX-airport, 03772 for London Heathrow, Frankfurt is 10637, Beijing (PEK) is 54511, Johannesburg is 68368, Sydney is 94767 ... and so on.

Warg, Thanks foe EDucating Ed some more.

I carried messages from the Radio Room up to the Weather center on the upper level of the Navy Ships I served on.
It was a whole new world up there. To Me

In civilian life, I worked at a Lock and Dam on a river.
6AM in the morning my shift read the Thermometers in the WX Box and noted the condition of the sky to include in our Morning Report of the river levels abovea d below the Lock.

As a Amateur Radio licensee I attended a SKYWARN class to learn how to report Severe WX.

Rug Rat,
Because a Junior High School friend delivered newspapers to my home, I would often walk along with him as he delivered papers.
He had a Novice license, and was a year older than I was.
He met a fellow in High School who had his Novice license too and one day that friend walked along as the newspapers were delivered.
These two guys talked to each other whistling Morse Code and I had no idea if they were talking about Me.

I went to the Library to find a book to help me learn Morse Code (CW).
The book I found was a U.S. Army Manual called IIRC An Menomic Device for Learning The International Morse Code.

I still recall the instructions for the letter P.
The word Pan was shown as: P = a n
.--. = .- -.

Pan was easy for me to remember.
Z was hard for me to learn until I got issued the Novice Call KN4ZIQ .

My Phonetics for the ZIQ letters is: Zero Intelligence Quoation.
I passed the Novice Test in the summer between 10th and 11th Grade .

Because the wife thiught the wires I had running out of a doorway in one room and going up through the Attic Stairway looked ugly to her I removed them and haven't had a A1 QSO on my HF rig since.
Although when vehicles pass by me on the road I often will look at the letters on their License Plate and "sound out" by thinking of the letters in Morse Code.

As I wrote above I learned Morse Code to defend myself if my Paperboy and his friend ever talked about me in code againwhile Isas walking with them.
That was 70 years ago.

Another story: I was driving through a City in another State, talking to someone on 2Meter Mobile when another ham joined the QSO and accused Me of not owning a Amateur Radio License because my Call Sign now is W9ODR which indicated to him that I lived up North since the Ninth Call Sign Area is Illinois, Indiana, Wisconsin area.

I told him when I got my Novice License I lived in Kentucky and my accent stayed with me when I moved to Indiana , and if he didn't believe I was licensed I would say the alphabet backwards over the microphone, and started saying:
DAH DAH DI DIT, DAH DI DAH DAH, DAH DI DI DAH, DI DAH DAH...
ZYXW... and unkeyed the mike.

If the Audio circuitry fails on your radio you could still use the radio to communicate by clicking the PTT Button ro send code.

I haven't listened to see if anyone still used the CW portion of the Ham Bands, guess I just made a ROUNDTUIT for myself to listen to see if their is any CW attivity now on HF.

Unfortunately there are.. CW will never die.. Though I glad it was removed as a testing requirement.

I am a happy NO CODE extra.. :) Though I did do the code test for the General many many moons ago..

Never liked the code, will never like the code..

I entered a reply but it didn't get rcvd by the BBS
Iguess Maybe I"timed out" the BBS too.

My reply was Longwinded.

Amateur Radio has many Modes to use and some Hams enjoy using one Mode over the others.
My Station has been used on CW, AM, SSB, FM and RTTY.
But that has been a long time ago

I think I could still pass the Avanced test if called to do it.

I really enjoy RTTY, and SSTV...

Advanced test, now there is another test I failed multiple times.

My problem with the Advanced was the MATH, and the new Extra incorporated a lot of it. The books just never did a good job of explaining the MATH! They basically just feed it to you from a garden hose all at once, and I would just get lost in the formula.

The W4EEY Online courses was the first material that could make it make any sense, as they showed you only the formula or operations needed to answer the question. So taken as their seperate elements, I could see okay each of these fomulat represent this part of the big picture, but this question already gives me these values, I only need ONE formulae to solve for what they are asking and it is this....

I probbably could not pass the test today, as I did a brain dump the second I walked out of the testing center.

Just imagine if they did the same kind of tests to earn/maintain a driver's license ... and I mean the level of difficulty.

Don't rememeber the DL test being all that hard, certainly did not study it as much as I studied for my amateur radio license..

Rug Rat, Slow Scan TV I have read about and I may could build a board from what I have read (years ago).

i don't know if Fast Scan TV still has anyone doing it in my area anymore. Years ago I participated in Field Day at a park and heard that near the park a Ham ran FSTV so I walked over to the QTH, introduced myself and got to see the gear
He was running a 432 Mc/s rig and told me several Hams inthe County also were on the frequency.
At that time I never had operated on VHF and didn't desire todo that.
My first VHF experience was listening to 2 Meter QSOs on the same portable radio I could tune to the Air Band. Listening to that Repeater I later bought a friends crystal controlled rig and got in the 2M group.

MATH, read your comments on that subject made me think about when I bought a TI-30 calculator whichalso had a Book called Math on keys.

Plane Geometry was the highest level Math Class I took in HS.
The calculator book helped me learn Trig (somewhat).
Also I have a book published by Howard Sams called Handbook of Electronic Tables and Formulas. It is a big help to me.
I canrecall some formulas but I also have problems with a lot of the deeper stuff.
Nowadays if I need help DuckDuckGo comes to the rescue.

Now IF I could get straightened out on the English Alphabet, ZYXWVUTSRQPONMLKJIHGFEDCBA .

Ward, In my 20's a Taxicab Company offered Driving Lessons and I paid them to teach me how to drive a car and was able to take the test to get a Drivers License ( You're thinking the roads are not safe anymore) .
The driving instructor had me go to rhe area the State did there test at and taught me what I needed todo to pass the driving test, everything including turning the key off after parking.

So I passed and drove the instructor from the test site back to the Cab Company.
Then I took the Bus home (some months later I began shopping for a car.).

LOL. So we can keep this somewhat on Aviaition (before we get yacked at for being off topic...)...

I was thinking of a snarky (I believe sarcasm makes the world go round) way to not only comment you are using the old Mc/s unit, but said 423Mhz was VHF...

This made me think of a "discussion" I had at the aviation school I work at. He called the 220Mhz aviation band UHF.

VHF is 30Mhz to 300Mhz
UHF is 300Mhz - 3Ghz.

So 220Mhz would still fall in VHF, though he would bet his life that it was part of the UHF spectrum, even when I pointed out that everything on the interwebs agreed with me.

So I went home pondering this, and then looking at it on paper it dawned on me what they did, and why they do it.

"VHF AM Phone" band encompasses 118 - 137 Mhz and is open for CIVILIAN use. "UHF AM Phone" avaition encompasses 225Mhz - 400.00Mhz. Even though 225Mhz is clearly in the VHF Range, and is for MILITARY and GOVERNMENT use only.

They are used VHF and UHF not to deliniate the freq. spectrum, but use. It is much easier to tell someone to GO TO Uniform BLAH BLAH BLAH, they say go to VHF hi... Work load is high, so keep it simple. Since 220 and above are probabbly on the same raido, it makes it even simpler. I don't have to rememeber that 220Mhz is on the UHF radio.).

So we were both right... He was just coming at it from the operational side and I was looking at it from the technical side..

Yep!, I use Megacycles per second.

I read many years ago that in America the only time Hertz should be used is if a person touches a 60 Cycle A.C. line.
They will get 60 Hurts per second.
