Video samples with audio
I got
couple problems to see these with My communicator,
so if
your browser dont automaticly start media player, try save these to your
hard disk and play it then.
These
videos work well with MS mediaplayer 6.01 version.
If you
find errors ect. in this page???
please,
let
me know ASAP!
Thank
you to visit here!
These are my hobby related site's and all
information is based my technical experience.
Reason why i made these page is cause i
havent find anywhere possiblity to comparage those receivers togerher or
any real comparison what is not "coloured" so This is my small contribution
to the hobby of monitoring.
maybe i'm too dramatical
when i say above,
in fact AOR 8200 cant
product audio when scope is working.
that's why in first
2 clips dont have audio but all wire's are connected
(as you can hear low
level hum there)
Time what is below file name is time
when video is recorded.
I've made those with
TV camera and Hauppage videocapture card
audio is feeded dicetly
to video card.
If some one know what packin method i should
use to get those videos smaller?
without loosing frame rate of those videos?
All ideas
are wellcome to me!
These first clips are from local WFM station
"Radio Plus"
With discone antenna in 25m high
AR-8200Mk2
(10MHz wide sweep)
2316Kt LONG!!
(no audio! cause AOR is unable to produce
audio when scope is on)
12. aug 2000 GMT 19.39
AR-8200Mk2 (2MHz
wide sweep) 975Kt
(no audio! cause AOR is unable to produce
audio when scope is on)
12. aug 2000 GMT 19.41
MVT-9000Mk2
M3.5 Scope (640KHz wide 10KHz resolution) 747Kt
With Marker function on (widest sweep with
10KHz resolution)
12.aug 2000 GMT 19.26
MVT-9000Mk2
M3.5 (320Khz wide 10KHz resolution) 956Kt
With minimum span (fastest sweep)
12. aug 2000 GMT 19.34
MVT-9000Mk2
M3.5 (+/-800KHz wide sweep) 889Kt
total 1.6MHz wide sweep (widest possible
sweep 25KHz step)
12. aug 2000 GMT 19.36
These Clips are 6.120MHz HF broadcast
station called "Radio Finland"
With 30 meter long wire antenna in 25m high
AR-8200Mk2 in WAM
mode(984Kt)
Not so good performance in HF band
12.aug 2000 GMT 19.58
AR-8200Mk2 in AM mode(616Kt)
12. aug 2000 GMT 20.01
AR-8200Mk2 in N-AM
mode(731Kt)
Best possible result with AOR in HF band
:-(
12. aug 2000 GMT 20.02
Actual program is possible to regonize in
this clip
(other wider AM modes dont give enough good
performance to made it possible)
This is exsample how poorly Ar8200Mk2 perform
in HF band.
AR-8200Mk2 in USB
mode(566Kt)
result is sad when comparared to yupi
When receiving AM transmissions in USB mode,
it cause distorsion
so SSB circuits and AGC in not proberly
desinged
12. aug 2000 GMT 22.11
MVT-9000Mk2 M3.5 in
AM mode(694Kt)
I really like Yupi with real reason ;-)
12. aug 2000 GMT 20.04
Only little squealing is heard but still
program is possible to regonize,
comparare this to AR-8200 N-AM performance
and this is still better than NAM mode with AOR
MVT-9000Mk2 M3.5
in N-AM mode(532Kt)
12. aug 2000 GMT 20.05
Sound is bit dark but it should be cause
filter is just 2.4KHz wide
MVT-9000Mk2 M3.5
in USB mode(1758Kt)
Yes, i do monitor quite ofter use SSB mode
when i monitor HF AM stations
As you can see that other side slope below
6.120MHz its other infering station
Bandscope resolution minimum is 3KHz /step
12. aug 2000 GMT 22.17
My way to get better sound (wider frequency
responce under inference's)
Here is sample of
Yupi's N-AM filter edge.
Quite long (2621Kt long)
With that 3KHz scope resolution and 1KHz
step
12. aug 2000 GMT 22.22
Radio move little bit cause i use arrow
key's to change frequency
Now
new addition
Yaesu
VR-5000 commincations receiver
Quite long klip of VR-5000 with DSP processor.
Taken 06.02-2001 SA 21.01 (Finnish time)
With AM mode, 15.420MHz, bandscope on.
BBC world service?9.493Mt long
VR-5000 AM HF reception
All feed back is wellcome!
