Re: [Elecraft] P3: Can the Panadapter be used with a Ten Tec Orion 1?

2011-10-25 Thread Dave Johnson
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.

Re: [Elecraft] P3: Can the Panadapter be used with a Ten Tec Orion 1?

2011-10-25 Thread nr4c
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!

Re: [Elecraft] P3: Can the Panadapter be used with a Ten Tec Orion 1?

2011-10-24 Thread Lu Romero
Hi Don:

Thanks for the response.  

Maybe Im not clear regarding what Im trying to do.

I have a dozen TenTec Orion 1's at a multi multi operation I
play at.  Im tasked with standardizing the audio
parameters for this operation in regards to compression and
frequency response before CQ WW SSB.  We want to make sure
that all the rigs sound as good as they can sound and have
consistent levels.  People play with these radios over the
ensuing months, so they are usually diddled to death by the
time I get there.

I have done this in the past by ear.  That is, I have
plugged a given rig into a dummy load and diddled with the
audio settings until I got it to sound right.  I wrote
down all the settings and went to another radio.  I set that
radio on a dummy load and input all the settings I wrote
down on the first radio.  I used the same microphone, the
same audio path and made sure the radios were at the same
software revision.  Lo and behold, the second radio sounds
different than the first with exactly the same numbers in
the software!  I have found in practice that no two Orions
sound the same, using exactly the same numbers and exactly
the same microphone and exactly the same voice (mine).

What I want to do is inject pink noise from a Flash Memory
WAV player that has a track from the NAB Audio Reference
disk.  I have the WAV player set to loop the file forever. 
Feeding it through a Radio Design Labs line level to mic
level amplifier block, the level coming out is 0 VU mic
level at a nominal 600 ohms impedance.  I want to feed this
into the mic input of the Transceiver under Test and, with a
spectrum analyser looking at the output of the audio
monitor circuit (yes, not ideal, but it gets me in the
ballpark) see where Im at.  I trust my ears, but it would
be nice to be able to see the waveform on the SA.  Knowing
where I am at, I can then adjust the rig's settings and even
pre-distort the audio input from external processing
(several transceivers are driven through W2IHY processors)
to optimize drive, punch and inteligibility.

As I said, I have done this by ear in the past.  But now I
have a P3.  I can do exactly the same thing on my personal
K3 by disconnecting the serial connection.  I can then see
the output of the rig in the P3 via IF leakage, and I was
able to look at what pink noise looks like at my personal
station and the effect of applying EQ to the pink noise
VISUALLY on the P3. I could do what I have to do faster on
the Orions if I could SEE the waveforms.  It would save me
time I can use otherwise at this station. 

What I would like to know is if the P3 can, using any IF
leakage from the Orion's IF out, do the same thing as I can
do on my K3. Im not looking for any laboratory grade results
here, Im just looking for a ballpark image of the modulation
envelope that includes frequency domain information so I can
judge the flatness (or lack thereof) of the audio
frequency response of a given Orion rig.  This way, I can
twiddle the knobs and match the rigs as closely as
possible to a consistent starting point since the same
identical numbers dont seem to have indentical results 
across Orions as they do on K3's.  If the numbers gave
repeatable results across several Orions, I wouldnt have to
do this! I would just input the numbers into all the rigs
and have a consistent starting point for tweaking.  

I want to use what I have on hand, I dont want to go out and
spend money or time building things.  If I was still at my
old TV station, I would borrow the Tek Spectrum Analyser at
the transmitter, or the Anchor audio analyser at the studio
and be done with it, but I dont work there anymore and dont
have access to these tools, so I wanted to use what I had on
hand.  

Guess I will just have to try it and see if it works!  Or
maybe I will look on the web for a freeware or shareware
audio baseband spectrum analyser which runs on a PC laptop
which I can then plug into the headphone output of a given
Orion and observe the waveform there.  

I was just curious if someone had used the P3 for something
like this in the past.

Lu,

I don't like to discourage list members away from Elecraft
products, but 
I do not know if the P3 will do the task you are asking
about - it 
depends on what other equipment you have to use along with
the P3.  Yes, 
the P3 can do the job IF you have the other equipment to run
it for your 
immediate purposes.

I would suggest that you also investigate the Simple
Spectrum Analyzer 
by G4AON used in conjunction with Spectrogram or SpectrumLab
or other 
computer based FFT audio spectrum analyzer.

2011-10-24 Thread Merv Schweigert
If you protect the P3 input with some back to back diodes,  put a piece of
wire on the IF input,  dial up the P3 IF to the the freq you wish to 
listen to,  and the P3
will show you the received signal.
I think the caveat is to protect the input to the P3 or you will burn it 
up..

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.

[Elecraft] P3: Can the Panadapter be used with a Ten Tec Orion 1?

2011-10-23 Thread Luis V. Romero
Hi all:
 
I realize that the P3 can be set to function with various transceivers, but
can it be used with an Orion 1 (the original model, not the current model)?
 
Im not really interested in using the Panadapter for monitoring On Air
received signals (although that might be nice if it worked well for that
purpose as well because the scope in the Orion, well, sucks!).  No, what I
want to do with my P3 is use it as a local spectrun analyser scope to set
audio frequency response and equalization for transmission. Transmitting
into a dummy load and turning monitor on, I can hear the monitor output of
the Orion, but it would be nice to also SEE it as well to better and more
accurately shape the signal.  Yes its better to do it with another receiver,
but time is of the essence in this environment.
 
Lacking a audio spectrum analyser, but having a P3, I thought I could put it
to good use next weekend for setting up consistent audio levels and
processing in this Ten Tec environment.  I have 12 Orion 1 transceivers to
match and not much time to do it, so it would be a helpful tool to have!
 
Thanks in advance.
