Receiver test data
 
For those interested in receiver specs, Bob Sherwood has added to and
updated his interesting list of receiver specs.
Still nothing to beat the AOR 7030..!!
Receivers listed are from the oldies like the Kenwood R-600 all the way up
to the most exotic offerings.
See http://www.sherweng.com/table.html
The receivers are ranked according to their "Dynamic Range narrow spaced"
which is one of the most important parameters for that really serious DX of
signals with adjacent channel interference.

Don't take the specs too seriously though, as a good DX friend of mine runs
rings around me when it comes to exotic DX results and he has a modest Yaesu
FRG-7 (Frog) that he swears by.

Amen! An experienced DXers with an average radio can run circles around a
beginner with an expensive, hot rod receiver.

Other aspects of the entire signal chain are often overlooked or too quickly
dismissed. Here's my list of criteria, in descending order of importance:

1. ionospheric propagation
2. antenna(s)
3. receiving location (RF-quiet, noisy, at the beach for sea gain
enhancement, etc.)
4. the DXer's experience
5. receiver
6. luck!

Anyone else with a similar or differing list?

I agree with this your list in its order, however, in place of luck I'd
put "Perserverence." You can make your own luck if you keep listening
regardless of your equipment. Conditions are constantly changing.

This Is Why {IMHO} - There are more good AM/MW DX 'catches'
Heard with GE Superadios then all other Radios combined.

1 - The Total Number of GE Superadios being used for everyday
and all night {late night} AM/MW Radio Listening.

2 - The Total Number of Daily and Weekly Hours that
the User's of GE Superadios are :
listening, Listening. LISTENING ! to their Radios.

3 - The Numbers Add-Up and Multiply - IF It Is Out-There -
The-Chances-Are someone with a GE Superadio is searching
for it (what ever it is) or will happen on it and one of them will
"Hear It" on a GE Superadio.


sometimes quantity does trump quality - iane ~ RHF

More than car radios? Doubtful.

David,

Consider the Read Profile of someone who Reads and Posts
to Rec.Radio.Shortwave - They are NOT your average Radio Listener.

Next consider the Listening Profile of someone who Buys a
GE Superadio to Listen to the Radio Every Day and All Night
and again - They are NOT your average Radio Listener.

Then consider the Listening Profile of someone who simply
owns a Car / Truck and Listens to the Radio in it while they
are in it Driving down the Road of Life - Now "They" ARE
your very average casual Radio Listener with :
* One-Eye-on-the-Road
* One-Ear-on-the-Radio
* One-Hand-on-the-Steering- Wheel
* Half a Brain Focused on Traffic
And with the other half of everything just plain doing
something else as they Cruise-Down-the-Road-of-Life !

David,

Yes there are 100s of Thousands of Truckers on the Open Road
but most are not Looking for AM/MW DX like many of the
GE Superadio Owners are . . .

Just like how many Open Road Trucker have a Shortwave Radio
in their trucks and Listen to it while they are Driving -Not Many !

Most likely many Truckers have an XM or Sirius Satellite Radio
and get what ever programming when ever everywhere anytime.

Why? Some receivers use multiple L.O.s in the same band to receive
multiple channels at the same time, and its a simple task to mix
multiple audio sources, or CDs would sound even worse than they already
do. You don't need 24 speakers to listen to a 24 channel recording.

I just checked the prices of SOLD Superadio II's on eBay and the average price
works out to $89.98.

I have seen them go as high as $175.00 or so.

Like eBay reflects reality.

Any 1960 vintage 5 tube superhet will run circles around a
''Superradio''.


Hardly. The reason folks like the GE radio is that it has a tuned RF
stage to get good reception fed to a decent speaker so you get decent
sound. The 6 D cell batteries last days not hours a a sound level
that is usefull in a decent sized room. That's assuming you can't use
the power cord. The 5 tube superhet's were no better if as good for
reception but forget battery life. Most did not do FM.

They used to build some very sensitive radios. I still have a "transistor

I've played with modifying the AGC and it made it even more sensitive.
Biggest problem it has is the small analog dial; very hard to tune small

So,which companies do you think build the best Aircraft Engines,Aircraft
Engines that have never failed,either in the Air or on the Ground?
Heck,I dont know.I dont know which are all of the companies nowdays
which build Aircraft Engines.I can think of a few of them though.I guess
I could look them up on the internet,but I can't see why I would want
to.Mechanical thingys do fail,sometimes,they are not perfect.I think
G.E.Aircraft Engines are A OK.
