How Many Watts Dead Key do Aviation radios have

There's been several instances where I've spoken with operators on CB who have claimed to be airborne, most notably a year or so ago with a military air crewman a communications specialist while flying over the Midwest. I believe his claim was legitimate frequently hearing him on 38 LSB he would pop in for a few moments making a few contacts before disappearing. This was happening fairly regularly for several months the station could be easily recognized by it's unique sound.

Interesting post.
I have had several conversations with aircraft over the years, one most notably was a communications operator aboard a "un-specified" aircraft during nighttime touch and go landings.
He did say they were at Edwards AFB, he was also using LSB mode, but would keep changing frequencies a lot.....when asked why, he said that he did not want to be caught on the CB frequencies by his superiors.
We would chat for several minutes, he would say they were going in for another touch and go and I would lose him, then he would pop back up and ask me to QSY to a different Frequency.
Lol, he was surprised that I had the capability to go up into some spectrum he did not think I could get to.

This next one some of you will think is shins, but I can assure it did happen.
I was working DX on the base one time, spinning the dial, when I ran across a guy calling North America.
I answered his call, and he asked me if I had an Internet connection and could pass a message to some friends that were on the old CB tricks Forum.
The message was that he had completed his mission, and would be back in New York in two weeks, he was doing well and everything was OK.
I went to the Forum, posted his message and was thanked by several members for the relay.
I got a PM there from one of his friends.
His Name was Colonel Xavier Stevenson, he was with an elite group of military in Afghanistan , in the Tora-Bora region looking for....Osama Bin Laden.
Turns out he was a part of MI5, the British version of the Secret Service.
About a month later, I got an E-Mail from Xavier, with an attachment.
He thanked me for passing his message along, and sent me a QSL card that featured The MI5 logo and his contact Info.
During the next year or so I keep in contact with him via e mail, he became Ill, and found out he had cancer.
He has now passed many years ago, but I will never forget that contact.
You never know who you will run across on the Air.

I think I misread this post from the start. Are you asking in you put a CB in a plane? If you install a CB in a plane and go up 1500 feet you will have lots of coverage, many many more then you would have on the ground.
 
I wish I could, It was on a old hard drive and I lost it when the drive failed.
Some of the old members on Cb tricks will remember.....this was back when John Mahoney Had his forum up on Panther Electronics.
Chris ( FireBreather), Richard, (SS8541) and a bunch of the guys were there.
When the old CB Tricks forum crashed all of this was lost.
I really wish I had printed the card, had a picture of an Iceberg on it and the phrase:
"Only 10% above the surface" referring to the hidden part of MI5

This whole thread makes no sense, but it does make me thankful I never got into drugs.

As for the power output of aviation radios IIRC the VHF AM mode radios run 25 watts carrier and the SSB mode usually run 100 watts pep with some a bit more. I did some work for a local municipal airport several years ago, rebuilt the power supply/battery charger in their base radio, installed new antenna on the office/ATC building, installed an RF activated landing light system so pilots could turn the runway lights on/off as required from the air when there was nobody at the airfield etc, and this is what I found out anyway. The base radio I worked on was a 25 watt radio turned back to 10 watts carrier as it was all that was required at the location.

As for comparing the range of an aircraft radio to a CB radio we may as well compare apples to golf balls. They are both round but beyond that there is not much in common. A 25 watt VHF aircraft radio at a couple thousand feet can work a base station 100 miles away with great clarity but what does that have to do with a base CB working a mobile CB in a truck anyway? :confused:

CB for the most part is line of sight. There are exceptions to the rule such as skywave propagation....but yes, the more your antenna can see due to elevation, the better your chances are of getting heard further.
 
HF (CB) is far from 'line of sight' like VHF/UHF. Any antenna will benefit from height but the reasons for that 'benefit' vary quite a bit depending on the band of use.

Revisiting an old thread as I spent the Winter based in the Canary Islands and every fourth day had to fly to and from either Finland or Sweden as part of my job. I'd carried out some research on the subject of operating /AM Aeronautical Mobile, and whilst illegal in the UK and Italy, it's legal for everywhere else in Europe.

With the legal issues taken care of it was dependent on route flown and captains decision as to whether I could use the HF radio, it was an absolute blast, with the biggest pile ups I've ever experienced,. As for the output on HF? 400W PEP, I detailed it all, including pictures of the installed equipment, on my Blog here:

Mobile HF Amateur Radio

And here's what is sounds like like:

Significant relative motion between two radio antennas can cause noticeable Doppler shift if you're operating on SSB. If your uncle drives past your place too fast, you might not understand him...:whistle:

The first time I tried 2m SSB was while mobile. I was traveling on the highway and scanning when I heard some SSB activity so I decided to try and join in. They sounded not too band on my end but I got awful reports of sounding "like I was under water and FMing somewhat". I thought I had something wrong with my radio. Later I tried it with someone I knew on both 6m and 2m SSB while mobile and 6m was perfect while 2m was not bad when parked or driving slow but got worse when hitting highway speeds. That was a learning experience that day between the Doppler effect and picket fencing.
