Name Your Transmission Preference

[CO Liberal]

If you one more than one vehicle, base it on the vehicle you drive more often.

1. Frequency Modulation for me!

Although it doesn't carry as well as AM, there's a lot less static and better frequency response!

2. You Fm'ers and

your fancy quadrature detectors. :grr: Give me a 455Khz local oscilator to beat my signal against & I'm a happy boy!:crazy:

3. VW has a 6 speed automatic

Most German highlines have at least 5 spd automatics

[Kellanved]

7. the benefit of which is questionable

The "pro" crowd argues that it might lead to a mileage superior to the mileage an experienced driver with a five-gear-manual transmission can achieve. Especially so in inner-city traffic, as the added gear helps at the speeds from thirty to fifty kph.

The "con" crowd argues that the six and seven gear automatic transmissions only result in a marginally improved mileage and driveability, while the transmissions are far more expensive and far more fault-prone.

Then again: nobody uses ATs in Germany anyway ;-) .

4. You Guys Have a Lot of DU-ers Scratching Their Heads

Talk of detectors and oscillators is lost on those with little or no electronics training.

8. DeVry! Thats why!

Basic radio theory, sorry. You Knew it back in '73. Just playing on the play on words. Now hand me that Fallopian tube behind you so I can fix this radio! :silly:

[CO Liberal]

9. Thanks to The Lab Kits We Used at DeVry....

... I thought that everything in the world ran on 12AU7 triode tubes and 2N404 transistors.

:-)

13. Hey! Let's have a DeVry reunion!

I went there too Class of '88

15. Wrong! Wrong! Wrong!

The world runs on the 6L6. :evilgrin:

My buddy Brian, who was one of our radio mechanics until he got out of the service, carried this damn tackle box to the field with him every time he went. No one ever saw him open it. No one knew what was in it.

Finally, curiosity killed Colonel McGuinness's cat and he opened it. It was full of 6L6s. At least fifteen. He carried them around as a talisman, figuring that if he had all these 6L6s in his possession, the all-solid-state gear we used would never go down. I don't remember it working all that well, but if it made Brian happy, what the hell.

10. Uh-Huhhhhhhnnn...He said "Beat"...

I fart in the general direction of your pentagrid convertor and state without reservation that 12 Kcs. COFDM rocks...

16. He said "transmission," not "modulation"

I like space-diversity troposcatter myself--you only need one transmitter and one registered frequency, and you can clear mountains with it. Frequency diversity's not too bad if you have a compliant frequency manager, but it takes multiple transmitters and a bigger generator to drive all of them, if you're on a remote site, or a bigger light bill, if you're in a fixed location.

Polarity diversity's cool too, but if you're running polarity diversity you are by default also running space diversity, because you can't do polarity diversity on one antenna.

Time diversity is too damn hard to get your head wrapped around.

Line of sight sucks ass, man, you gotta put a repeater on top of the mountain to clear it. The Forest Service has a slick way to do LOS down to the crews in the canyons: they put repeaters on top of various hills then run LOS microwave between them.

As far as modulation goes, I love PCM if you've got a digital setup and frequency-division-modulation if you're on an analog carrier. You can lose synch on a time-division radio, but if you're running FDM, you transmit a pilot tone and your receiver knows what to do with it, you're golden.

5. I have fond memories of the old Ford C-4

fourspeed they put in the '62 Falcon. I could bench press that one, which was lucky, since I seemed to have it out of the car several times a year.

[Feanorcurufinwe]

6. oooh I hate automatics. n/t

[BiggJawn]

11. Damn Tempo 5-speed destroyed my left knee!

I swear, that clutch spring must have been out of a E-350 or something.
I have 3-speed Auto with O/D in my Ranger so nice, not to have to stir the cogs constantly in-town...

[BiggJawn]

12. Sturmey-Archer AW...

The 3-speed on my "Pizza Runner"....

14. I'm not all that knowledgeable on transmissions

But I know that when I put my car in drive, it goes. That's all I need. Park, neutral, drive and reverse work for me.
