[TowerTalk] AIM4170 calibration help

[Jorge Diez - CX6VM]

Hello

I have an old AIM4170 and I want to run it in a new computer

I open the software and it told me that I need to calibrate

I did standard calibration, when I connect the short circuit connector a
message that say

Cal Load Warning
the load impedance is aproximately 20152.979 instead of 0 ohms. Do you want
to continue? I said yes and it go.

Then I attach the open circuit
Cal Warning
there seems to be a long stub on the RF connector. The cfalibration may not
be accurate around 2 Mhz, Do you wan to continue? I said yes and it go

Then I attach the standard resistor (200 ohms) and another message
Cal Load Warning
The load impedance is aproximately 16659.519 instead of 200 ohms. Do you
want to continue?
I continue

Another message: make sure the loads were correct for the short and open
cal procedure

After that: do you want to save the new data. I save it

Calibration is complete NOTE Zref=50

But when I want to scan an antenna the results are vert strange

Seems something wrong when calibration, right?
