Band voltage with Hermes-lite 2 don't work

[dl1bz]

I have a Hermes-lite 2. If I activate the option "Band voltage" for the Hermes-lite 2 I ever get the same output voltage from the HL2, independ which frequency I select - no changes.
With other software (in this case Thetis) all is working correct, but not with SDR Console. I use the last beta from December.

I requested this feature but unfortunately I'm not yet in a position to test it for Simon despite it being added some time ago. I assume you are trying to obtain the band volts from the fan output on the modified rear panel of the HL2?

I just checked diagnostics and the address (0x00 [11]) does seem to be set correctly. See attached pictures.

Are you using the IO Board or not?

Sri for late answer. I use the PIN 4 "FAN or BAND VOLTS PWM"of DB1 connector. Depend from initialisation of gateware you can use this output als fan pwm output OR bandvoltage output. I use my own interface, because I put this output to an ADC of an ESP32, which control my XPA125B. If I measure the voltage with SDR Console, I get only one voltage, independly which band I select. As I say before, if I activate this option in Thetis, I can measure different voltages if I switch the bands. Thats ok.

That's odd Heiko. Hopefully Simon will be along and read this soon. It would be good if you can join the Test Team to solve this issue.

Max just alerted me to this - I'll look at it. May I invite you to the test team?

Hi,

I've checked the code, looks good. I've asked for clarification in the HL2 mailing list, will wait for answers.

Thank you Simon. Yes saw your post over there.

I emailed Heiko via QRZ address to ask him to check back and hopefully respond here. "Read receipt" but no response just yet. Hopefully he can come back here and test. If not I will try to verify it if I can but not installed the band-volts mod on my HL2 so not sure if I will be able to just yet.

With pleasure I will join the Test team. Maybe I can help to solve this issue.

Heiko, it looks like Reid on the HL2 Group has solved the mystery.

You must activate TX DSP panel on SDRC in order for the band volts to work. Seems that only when TX frequency set is sent to HL2 that the band volts change.

Sorry, I had assumed in original post that you had TX DSP activated. This is why always useful to post a screenshot with initial question. Must be attached not inserted into text as an image. Also should be full uncropped screenshot:

Anyway, hope the issue is now solved for you?
