Re: Direct I/Q and Spectrum Lab
Hi Alan, it's all about dynamic range. 80m bandnoise usually is about -120dB fullscale, input noise of the Anan's somewhere at -150dB FS. You have to make sure that your audio chain and the used spectrum app supports HDR. 16bit resolution is definitly not enought (only 96dB), you need at least 24 bi...

Re: Transverter Questions 7000 DLE MK2-3 whatever?
Hi Robert, the SMA XVTR output is for max. 0.5W only. If you need more you have to use the internal PA on one of the three ANT x BNC's. Use the setting below for PA activation: 5W XVTR.png Don't forget to calibrate PA Gain for maximum allowed input of transverter: XVTR PA CAL.png greets Walter DL2XY

Re: Thetis v2.9.0.8 - meters and then some more
Just calibrate your panadapter!
The value is roughly the attenuation of your coupler, maybe you have to adjust a few dB.
Scale the tx-display and make sure DUP is enabled.

Jay n2gq
-43dBm (S9+30) should be sufficient.
-20dBm(S9+53) would be still better since at least15bits of the 16bit ADC are used.

Re: Anomalous S meter reading on 6m band only
Your values reflect exactly the IARU recommandations for S-meters:
HF: S9 = 50µV = -73dBm
VHF: S9= 5µV = -93dBm
So everthing is perfectly fine.

Re: Not sure how to use Open Collector Jack and Thetis settings...
An OC is simply a switch towards ground if activated.
There is no intrinsic pull up.
If you want to switch inductive loads (Relay coil) it is mandantory to use the COM pin for freewheeling.

Or you may try to patch the database directly.

Re: S Meter issue ( not fixed )
. By default Thetis reports about 7dBm in excess, ( a calibrated -73 turns into -66 dBm.) Do not calibrate at -73dB ! This is an ADC-System, ADC's need to be calibrated near fullscale. -20dBm should be fine. Calibrating at S9 means 1/1000 of fullscale voltage, so the software must extrapolate by a ...

Minimum AM carrier is 0.25W at drive level 1.

The PA calibration is per radio model. You can have both radios (must be different models) in one database.
