[Lowfer] Argo V1 Build 143.

[Michael Sapp]

Kurt:  I had the "deer in headlights" experience when I first downloaded and 
installed ARGO Build 143 as well.  You need to enter your operating 
frequency with an adjustment for the radio's BFO center frequency. That is 
dependent on your SSB or CW sideband setting on your receiver.  For upper 
sideband, you subtract the BFO center frequency from the dial frequency of 
the radio and enter it in the "Setup" section under "Calibration."

Choose "Setup" on the tool bar, then choose "Calibration" which is the third 
option down the list.

A window will appear called "Argo Frequency Scale Calibration".

For initial setup, enter your receiver's BFO center frequency in the 
"Measured Frequency" and "Displayed Frequency" data field windows (center, 
left)

of the Argo Frequency Scale Calibration window.

In the "Offset" data field window (center, right) enter your "dial 
frequency - BFO center frequency" if you are using the receiver in upper 
sideband (phone or cw).

(If you decide to use LSB, then the BFO center frequency is added to your 
dial frequency and entered into the "Offset" data field window.)

Press "OK" at the bottom of the "Argo Frequency Scale Calibration" to save 
your settings.


Once you have an initial setup, perhaps it would be worth testing it out 
using WWV or WWVB as a reference signal.

For example, once you have the "Hz" scale on the right side of the ARGO 
screen working as you want it, then try using the "Measured Frequency" and 
"Displayed Frequency" data fields in the Argo Frequency Scale Calibration 
window  to fine tune the "Hz" frequency scale.

You can enter small changes to either of those data field's with the BFO 
center frequency entered to have the WWV or WWVB carrier trace shift up or 
down where you want it... (e.g. change a BFO center frequency from 500Hz to 
501Hz or 500.1 Hz, etc.)

If you make a 1Hz or .1 Hz change to the previously entered BFO center 
frequency, it will show up as a carrier trace shifting up or down on the 
waterfall Hz scale. If the waterfall trace moves in a direction away from 
the desired Hz scale frequency, then enter a small correction change to that 
BFO center frequency in the other direction (+ / - ).

I chose to leave my BFO center frequency "as is" in the Measured Frequency 
data field window, and make adjustments to the "Displayed Frequency" window. 
(But it will work in reverse the other way around).

Remember to select the "OK" button at the bottom of the Argo Frequency Scale 
Calibration, window to save the settings.  It's a decent program once you 
get the feel for it....

I wrote these instructions during morning coffee and checked them three 
times. If something above appears to be out of sorts, please bring it to my 
attention
and I will review, correct, clarify as needed.
