Hello
Subject: Orion 565 with Firmware 2.064X11
After my S-Meter Calibration with a Generator and the Setting- List with the
normal unknown hidden menue via the Button for MENUES- RX and 15, the Power
Indication for 100W was only 70 Watt. Yes i thing also i must be readjusting
the S-Meter with the Potmeter a little bit again to the S1 Startingpoint,
above the AUDIO Button at the Frontplate , than we can adjusting the
excactly S1 with the Settinglist and again i think only these for all
Settingpoints with a Generator!!!
I startet the alignment with the S9 plus 50dB, because the Output from my
Generator make only 19mV into 50 ohm and with the Multiknob to the desired
S-Meterindication, the maximum is 255 for S9plus 60dB, for S9 plus 50dB my
Settinglist Number is 222 and for S1 is the Settinglistnumber 32. My S-
Meter now is excactly from S4 to S9 plus 50dB with PREAMP off.
The S3 need 1µV instead of 0,794µV and S2 also more.
I know we need a Alignment adjusting procedure from TT.
But these Discussion was very helpfull for me, startet with the before
unknown hidden menue, many Thanks to AL7CR.

calibration
Hmmm...After re-flashing the firmware I find that the S-meter settings in
the "secret menu" are unchanged from what I entered myself. If they are not
loaded by the firmware where do they come from? Doesn't really matter
though, the ones I entered work just fine.
Out of curiosity it would interesting to know what the settings are in other
Orions that have the S-Meter menu available (MENUS..RX..15M button)
Beginning with S-zero my level settings are 0, 16, 27, 38, 46, 54, 62, 70,
78, 89, 99, 113, 130, 148, 171, and 198.
Any others for comparison?

I have sent a message to TT service asking that exact question. but haven't
heard anything yet. But, I have been playing with it enough to know that
there are several interrelated parameters involved.
I decided to start by setting the one parameter which I could verify
externally, the TX POWER. Setting the ALC SET pot to make the TX put out
100W and then adjust the meter pot to make the meter read 100 was my first
step. I figured that would at least set the meter pot in the ballpark for
both TX and RX.
Next I went to the "secret" menu and set each level to the number of counts
that made the meter read the corresponding signal strength. As it turns out,
the S9+60 reading is achieved with a count setting of 198, not the max of
255 that I had expected. If I redjust the meter pot so that 255 counts reads
S9+60, then the TX POWER reading is off.
Then there is the matter of the SWR reading displayed on the Orion. I assume
that this reading is a calculation made by the Orion based on signals
calibrated by the PWR and REF pots which also affect the reading displayed
by the analog meter. I also assume that this calculated SWR is used to tell
the auto tuner when it's done.
I've done a lot of assuming in all of this but I feel there has to be a
methodical procedure for calibration of all these pots and settings written
down somewhere. But the fact that the pots are not labelled makes me think
there is no reference to them in any service manual or other documentation
that the user is intended to use. I'm pretty sure that mis-adjustment of any
of the pots or settings will not result in damage to the radio. With the
exception of the auto-tuner function, I feel that they just affect readings
displayed on the front panel, but that is my opinion and worth what you paid
for it!.
One thing I haven't done yet is to reload the firmware and adjust everything
starting with factory settings of S-meter levels.
Sounds like a good project for after lunch!
