Re: P3: Can the Panadapter be used with a Ten Tec

[Lu Romero - W4LT]

Yes, that would work, but then I would also have to take the
K3 with me as well.  Trying to travel "light".

Several have made the suggestion to place back to back
protection diodes on the P3 input, set the P3 to a
convenient below 22mhz frequency, tune the rig being tested
to that frequency and the P3, being a self contained
receiver, will show the waveform.  I think this is the
direction I will go.

Hi Lu,

Why not just tune the K3 to the RF output frequency of the
Orion?  The
K3's IF output signal is picked off before the crystal
filters, so the
P3 shows the actual unfiltered signal received at the K3
antenna
connector.

I now have that software, so this is also a way to skin this
cat.  

But then I dont get to show off my P3 :)

Lu,

Perhaps an easier method of accomplishing what you want to
do: You stated
that you do not have an audio analyzer, so that is why you
are considering
using the P3 to set up the Orions.

 

Why not oad free Spectrogram or Spectrum Lab audio spectrum
analyzer
software on a laptop, and use that to observe the output of
the monitor
circuits?

 

Bruce, N1RX

Unfortunately, no access to an SDR.  If I did, I would have
a "spectrum analyser" already hi.

It would be even easier if the darn Orions interpreted the
numbers on their software consistently or would even sound
consistently similar.  Some are bassy, some are tinny, some
are mushy, and this with the exact same mic and voice and
exactly the same numbers input into the firmware!  Ah well.
If it was that easy, they wouldnt need me to tweak the rigs
then, right?  :)

Lu, if you have access to an SDR receiver that can record
it's output
on a PC, it might be easier that using a noise source.

When comparing several microphones and headsets on my K3, I
used a
Perseus SDR to play back the results for A/B/C/D comparison
in order
to pick the best equaliser/mic combination. The saved files
from the
Perseus were labelled to match the microphone and can be
played back
very easily, in addition, recording a wide chunk of
frequency means
the bandwidth can easily be checked if that might be an
issue.

True, Bill.  I have also found out that different vintage
Heil ProSet DX4's have different output levels and frequency
response.  The older ones have hotter output than the newer
ones.  Also needed to be taken into account are male vs
female voices (we have female ops as well). And different
mic technique.  Lots of variables!  Im trying to minimize
them as much as possible.

I realize that different voices will give different results,
but if you find a good "normal" from a compression and mic
standpoint and stick with it across all the rigs, and keep
people's fingers out of the settings when they are trying to
"help", you dont end up with mush and splatter.

And the key in any contest is for them to UNDERSTAND the
exchange, so the more articulate and clear we make the
transmission, the easier it is for the other guy to copy us
correctly and log us.  We aint talkin' about broadcast
quality hi-fi here, we're talking about being heard and,
most importantly, being understood above the cacophony in a
phone contest with lots of QRM and mis-tuned amp IMD flying
about.

Actually, last year we decided to "assign" headsets to
particular radios due to the idiosyncracies of the rigs and
the mics. That rule lasted most of last year's contest, lets
see how long it lasts this year :)

You can have a big signal, but if they cant understand it,
you may as well run QRP.  Just cuz the meters are swingin'
WAAAY to the right dont mean they can understand what youre
sayin'

Pardon me, but I have read a lot of the traffic on this
topic, and some
very good ideas have been considered.  Recorded audio into
the mic jack
or a sound source as in a 'pink' noise, or ''white' noise
allows the
radio to be adjusted.  I have a K3, so I can use it with the
P3 to
analyze the audio of my other radio(s) while transmitting
into a 'dummy'
load.

But, none of these account for the difference in mics.  A
station with
a dozen radios and a dozen mic is still going to show
differences in
transmitted audio due to different mics and mic
usage/voices.

I'm glad I don't have to do this!
